2022 Edexcel A-Level Geography (9GE0) 模擬試題連答案詳解

Step 1: Identify the variables from the question: \(n = 24\) years, \(m = 5\). Step 2: Substitute these values into the formula: \(T = \frac{24 + 1}{5}\). Step 3: Calculate the value: \(T = \frac{25}{5} = 5\). Therefore, the recurrence interval is 5 years.

1 mark for showing correct working: \(\frac{24 + 1}{5}\) (method mark). 0.33 marks for the correct final answer of 5 years (accuracy mark). Accept: 5, 5 years.

Step 1: Calculate the total retreat of the cliff over the 12-year period: \(84.5\text{ m} - 58.1\text{ m} = 26.4\text{ metres}\). Step 2: Calculate the mean annual rate of retreat by dividing the total retreat by the time period (12 years): \(\frac{26.4\text{ m}}{12\text{ years}} = 2.2\text{ metres per year}\). Step 3: Format the answer to two decimal places: 2.20 metres per year (or m/yr).

1 mark for showing correct working of total retreat divided by time: \(\frac{26.4}{12}\) (method mark). 0.33 marks for the correct final answer of 2.20 metres per year (accuracy mark). Accept: 2.20m/yr, 2.20 metres/year, 2.20.

Step 1: Calculate the absolute decrease in carbon emissions: \(520\text{ Mt} - 338\text{ Mt} = 182\text{ Mt}\). Step 2: Divide the absolute decrease by the original 1990 emissions value: \(\frac{182}{520} = 0.35\). Step 3: Multiply by 100 to convert to a percentage: \(0.35 \times 100 = 35\%\).

1 mark for showing correct working of percentage change: \(\frac{182}{520} \times 100\) (method mark). 0.33 marks for the correct final answer of 35% (accuracy mark). Accept: 35.

A high Volcanic Explosivity Index (VEI) represents highly explosive eruptions, typical of viscous, gas-rich silicic magmas at destructive plate boundaries. These eruptions violently eject fine ash and tephra high into the stratosphere, where atmospheric winds can distribute them globally, creating a massive spatial footprint. Conversely, low VEI effusive eruptions involve low-viscosity basaltic magma, resulting in localized lava flows that present hazards primarily at a local scale. Highly explosive eruptions can also generate far-reaching secondary hazards like lahars or tsunamis if they destabilize volcanic flanks, whereas effusive eruptions rarely extend beyond the immediate volcanic slopes.

Award up to 5.75 marks. Level 1 (1-3 marks): Identifies volcanic hazards (e.g. ash, lava) with superficial explanation of how physical characteristics like VEI or viscosity determine their reach. Explanations are descriptive and lack clear links to spatial scale. Level 2 (4-5.75 marks): Outlines clear, detailed connections between magma characteristics (viscosity, gas pressure, VEI) and the specific spatial extent (local, regional, global) of primary and secondary hazards.

Lithology, or rock type, dictates the inherent strength and permeability of cliffs. Unconsolidated rocks like glacial till or permeable sands overlying impermeable clay (e.g., at Barton-on-Sea) are highly vulnerable to water saturation, which reduces shear strength and leads to rotational slumping. Geological structure, such as jointing and the dip of rock strata, determines mechanical pathways for failure. Seaward-dipping strata create a natural slide plane where gravity can pull weakened blocks downwards, increasing the frequency of landslides. Conversely, horizontally bedded or landward-dipping strata are structurally more stable, although vertical jointing can still facilitate freeze-thaw weathering and block fall.

Award up to 5.75 marks. Level 1 (1-3 marks): Simple descriptions of rock types (soft vs hard) or geological joints with weak links to mass movement types. Level 2 (4-5.75 marks): Well-developed explanations showing how specific lithological properties (permeability, consolidation) and structural elements (strata dip, joint networks) directly facilitate distinct mass movement processes.

Deforestation removes the forest canopy, which drastically reduces interception and evapotranspiration rates. With less moisture returned to the atmosphere, local precipitation recycling may decrease, exacerbating dry conditions. On the ground, the lack of vegetation cover reduces soil organic matter and root networks, causing soil compaction. This limits infiltration and percolation, causing a shift from subsurface pathways to rapid surface runoff during storm events. Consequently, groundwater stores are not recharged. During dry seasons, base flow (which relies on groundwater discharge) is severely depleted, causing river levels to fall and triggering hydrological drought.

Award up to 5.75 marks. Level 1 (1-3 marks): Identifies simple changes to the water cycle (e.g. more runoff, less trees) but fails to explain how these changes culminate in depleted river/groundwater stores (hydrological drought). Level 2 (4-5.75 marks): Provides a logical, sequential explanation linking reduced interception and compaction to diminished infiltration, depleted groundwater aquifers, and subsequent base flow collapse during dry periods.

Positive feedback loops amplify the original warming trend. One key mechanism is the thawing of Arctic permafrost: as rising global temperatures warm high-latitude regions, previously frozen organic matter decays, releasing carbon dioxide and methane into the atmosphere, which further traps heat and drives more thawing. Another mechanism is forest dieback: rising temperatures and shifted rainfall regimes induce severe droughts in tropical forests like the Amazon. This leads to tree mortality and widespread wildfires, transferring massive carbon pools from the biomass to the atmosphere as carbon dioxide, which exacerbates greenhouse warming in a self-reinforcing cycle.

Award up to 5.75 marks. Level 1 (1-3 marks): Identifies a carbon store or describes general warming without explaining the sequential, self-reinforcing nature of a positive feedback loop. Level 2 (4-5.75 marks): Clear, step-by-step explanation of at least one (ideally two) positive feedback processes (e.g., permafrost thaw, forest dieback), explicitly detailing how the carbon released amplifies the initial temperature change.

An excellent response should structure the assessment by evaluating the role of economic development against physical factors, supported by precise case study evidence (e.g., Haiti 2010 vs. Tohoku, Japan 2011 or Christchurch, New Zealand 2011).

1. **The Role of Economic Development (Vulnerability & Resilience):**
- **Developed Countries (e.g., Japan, New Zealand):** High levels of GDP allow for investment in earthquake-engineered infrastructure (aseismic design), comprehensive early-warning systems (such as Japan's J-Alert), community education (Earthquake Disaster Prevention Day), and well-equipped emergency response services. This significantly minimises loss of life.
- **Developing/Emerging Countries (e.g., Haiti, Nepal):** Poor economic development often leads to rapid, unplanned urbanisation with substandard building materials and lack of building code enforcement (e.g., in Port-au-Prince, Haiti). Limited medical facilities, poor infrastructure, and weak governance delay rescue and recovery, leading to high casualty rates and long-term economic stagnation.

2. **The Role of Physical Factors (The Hazard Event):**
- **Magnitude and Depth:** A high-magnitude, shallow-focus earthquake (such as the shallow depth of 13km in Haiti or 5km in Christchurch) concentrates seismic energy, causing severe destruction regardless of development level.
- **Secondary Hazards:** Tsunamis (as in Tohoku 2011), liquefaction (as in Christchurch), and landslides (as in Sichuan 2008 or Nepal 2015) can cause disproportionate damage. The Japanese tsunami overtopped sea walls, demonstrating that extreme physical magnitude can bypass advanced technological defences.
- **Location of Epicentre:** An earthquake directly under a major urban area (Christchurch) causes far more damage than a larger event in a remote area.

3. **Synthesis and Evaluation:**
- Economic development is the primary control over the *proportion* of lives lost vs. economic wealth lost (developed nations lose more wealth but fewer lives; developing nations lose a catastrophic percentage of GDP and many more lives).
- However, physical factors set the baseline of the disaster's potential energy. An extreme physical event (e.g., a magnitude 9.0 earthquake and massive tsunami) will always cause severe impacts, but the long-term recovery and immediate survival rate are heavily dictated by economic development and governance.

**AO1 (6 marks):** Demonstrate knowledge and understanding of how economic development and physical factors influence tectonic hazard impacts.
- **Level 4 (5-6 marks):** Precise, detailed, and wide-ranging knowledge of tectonic processes, human vulnerability, and contrasting case studies (e.g., contrasting developed and developing nations).
- **Level 3 (3-4 marks):** Sound knowledge of tectonic hazards and vulnerability, with some appropriate case study details.
- **Level 2 (2 marks):** Generalized knowledge of tectonic hazards and development with limited or unbalanced case study references.
- **Level 1 (1 mark):** Isolated fragments of knowledge showing little understanding of factors.

**AO2 (6 marks):** Apply knowledge and understanding to assess the relative significance of factors in determining impacts.
- **Level 4 (5-6 marks):** Coherent, balanced, and logical assessment that leads to a supported, nuanced conclusion regarding the interplay of physical and human factors.
- **Level 3 (3-4 marks):** Logical assessment showing clear understanding, but may focus heavily on one side (e.g., human factors) or lack a fully balanced conclusion.
- **Level 2 (2 marks):** Some straightforward assessment, but lacks depth; argument is largely descriptive.
- **Level 1 (1 mark):** Descriptively lists factors with no clear assessment or conclusion.

**Accept/Reject Notes:**
- **Accept** any valid case studies (e.g., Indian Ocean Tsunami 2004, Iceland Eyjafjallaj”kull 2010, Chile 2010) as long as they are used to contrast the role of development against physical characteristics.
- **Reject** answers that focus solely on atmospheric or hydrological hazards (e.g., hurricanes, floods) unless explicitly linked as secondary hazards of a tectonic event (e.g., landslide-induced flooding).

An excellent response will clearly define feedback loops and analyze both positive (amplifying) and negative (damping) feedbacks, evaluating their net effect on climate stability.

1. **Positive Feedback Loops (Destabilizing):**
- **Permafrost Thawing:** As global temperatures rise, Arctic permafrost melts, releasing trapped methane (\(CH_4\)) and carbon dioxide (\(CO_2\)) from decaying organic matter. This increases atmospheric greenhouse gas concentrations, leading to further warming. This is a crucial positive feedback loop with global consequences.
- **Albedo Effect:** Warmer temperatures melt sea ice and snow, replacing highly reflective surfaces with dark ocean/land that absorbs more solar radiation, warming the planet further and accelerating ice melt.
- **Forest Dieback (e.g., Amazon):** Rising temperatures and changing rainfall patterns cause drought, leading to forest fires and dieback. This transitions carbon sinks into massive carbon sources, reinforcing warming.
- **Ocean Warming:** Warmer oceans have reduced solubility for \(CO_2\), meaning they absorb less atmospheric carbon, leaving more greenhouse gases in the atmosphere.

2. **Negative Feedback Loops (Stabilizing):**
- **CO2 Fertilisation (Photosynthesis):** Higher atmospheric \(CO_2\) levels can stimulate plant growth and increase photosynthesis (greening), which removes more \(CO_2\) from the atmosphere, helping to temper temperature rises.
- **Chemical Weathering:** Higher temperatures and increased precipitation can accelerate chemical weathering of silicate rocks. This process converts atmospheric \(CO_2\) into dissolved hydrogen carbonate ions, which are eventually washed into oceans and sequestered as carbonate sediments on the seafloor (a slow but significant negative feedback).

3. **Assessment and Synthesis:**
- Students should assess the relative strength and timescales of these feedbacks. Positive feedbacks (especially permafrost melt and albedo reduction) operate on rapid decadal scales and threaten to push the Earth system past "tipping points"—thresholds beyond which self-sustaining changes occur that human mitigation cannot easily reverse.
- In contrast, negative feedbacks like chemical weathering operate over geological timescales (thousands to millions of years), meaning they are too slow to mitigate modern, rapid anthropogenic warming. While terrestrial greening provides some short-term buffering, it is limited by nutrient and water availability.
- Therefore, positive feedback loops pose a profound and disproportionate threat to the stability of the global climate system compared to the stabilizing capacity of negative feedbacks.

**AO1 (6 marks):** Demonstrate knowledge and understanding of feedback processes in the global carbon and water cycles.
- **Level 4 (5-6 marks):** Precise, detailed, and accurate knowledge of specific positive (permafrost, albedo, forest dieback) and negative (weathering, fertilization) feedbacks, using appropriate geographical terminology.
- **Level 3 (3-4 marks):** Sound understanding of feedback loops, but may lack detail on the specific mechanisms or cover fewer processes.
- **Level 2 (2 marks):** Generalized or unbalanced explanation of feedbacks, possibly confusing positive and negative definitions.
- **Level 1 (1 mark):** Identifies basic concepts of warming/carbon sinks without clear linkage to feedback loops.

**AO2 (6 marks):** Apply knowledge and understanding to assess the extent to which these feedbacks threaten climate stability.
- **Level 4 (5-6 marks):** Coherent, balanced, and highly analytical assessment. Clearly contrasts the differing timescales and magnitudes of positive vs. negative feedbacks, arriving at a well-reasoned conclusion regarding the threat of tipping points.
- **Level 3 (3-4 marks):** Logical assessment of the roles of feedbacks, but may lack a deep evaluation of timescales or tipping points, or have an unbalanced focus on positive feedbacks.
- **Level 2 (2 marks):** Basic assessment showing some understanding of effects, but largely descriptive or unsystematic.
- **Level 1 (1 mark):** Descriptive list of feedback effects with no real attempt to assess their threat to overall stability.

**Accept/Reject Notes:**
- **Accept** references to the water cycle (e.g., water vapour feedback) as it is deeply linked to the carbon cycle and climate feedback systems.
- **Reject** essays that do not focus on feedback loops (e.g., simply discussing human causes of carbon emissions without linking them to physical feedback responses).

### Introduction
- Define coastal recession and introduce the debate: whether rates of retreat are primarily driven by natural physical baselines (geology, lithology, waves) or are significantly accelerated/decelerated by human management strategies and interventions.
- Outline contrasting case studies to be used, such as the Holderness Coast (highly active, soft geology, heavily managed in parts) and the Dorset Coast (harder rock, structurally diverse, less intervention or different management approaches).

### Body Paragraph 1: The Dominance of Geological and Marine Factors (The Baseline)
- Discuss the fundamental role of lithology: weak unconsolidated glacial till (e.g., Holderness) retreats at 1.5 to 2 metres per year due to low shear strength, whereas resistant limestone or chalk (e.g., Flamborough Head or Dorset Purbeck cliffs) retreats extremely slowly (millimetres per year).
- Analyze geological structure: concordant vs. discordant coasts. Explain how dip of strata (seaward-dipping vs. landward-dipping) affects mass movement types (e.g., rotational slumping on Holderness, rockfalls on Dorset).
- Analyze marine factors: wave energy (destructive vs. constructive waves), fetch, and storm surges. Wave quarrying and hydraulic action are the active agents of erosion.

### Body Paragraph 2: The Significance of Human Interventions (Altering the System)
- Explain how human engineering can locally halt erosion but accelerate it elsewhere due to sediment starvation (negative feedback loops disrupted).
- Case Study Detail: Holderness Coast. Hard engineering at Hornsea (groynes) successfully protects the town but intercepts longshore drift. This starves Mappleton of sediment, leading to narrower beaches, larger wave energy absorption at the cliff foot, and rapid erosion rates of up to 4m/year south of the defences (terminal groyne syndrome).
- Discuss offshore dredging (e.g., Hallsands, Devon historical context or general modern dredging) which lowers the seabed, allowing larger waves to reach the shore without losing energy, massively accelerating recession.

### Body Paragraph 3: Synthesis and Interplay of Factors
- Argue that human interventions are often a *reaction* to extreme natural processes, but their significance depends on the scale of the sediment cell. On low-energy, highly resistant coastlines (e.g., parts of the Scottish highlands or stable Dorset cliffs), human intervention is minimal and geological factors remain entirely dominant.
- On high-energy, weak-lithology coastlines, human interventions can shift the local locus of erosion, effectively making human action the dominant short-term spatial control on recession rates, even if long-term rates are bounded by geology.

### Conclusion
- Conclude that while geological and marine factors establish the fundamental vulnerability and regional baseline rates of recession, human interventions are highly significant in localizing and accelerating recession rates elsewhere through sediment cell disruption. Ultimately, human actions do not override physical laws but shift the balance of wave energy along a coastline.

### Introduction
- Define hydrological drought: a deficiency in subsurface water, streamflow, and reservoir levels, distinct from meteorological drought (lack of rainfall).
- Introduce the core debate: physical systems (like El Niño-Southern Oscillation - ENSO, and blocking anticyclones) act as primary atmospheric triggers, whereas human activities (such as aquifer depletion, damming, and land-use change) modify basin hydrology and exacerbate water shortages.

### Body Paragraph 1: The Primary Role of Physical Factors (Atmospheric Controls)
- Analyze global atmospheric circulation systems. Shifts in the Intertropical Convergence Zone (ITCZ) cause severe seasonal drought in sub-Saharan Africa (the Sahel).
- Explain ENSO cycles: during El Niño, descending dry air over Australia and Southeast Asia causes prolonged high pressure and severe meteorological drought, leading to dried river beds and reduced groundwater recharge (hydrological drought).
- Detail mid-latitude blocking anticyclones (e.g., the UK 1976 or 2018 droughts) which push rain-bearing jet streams away, leading to extended dry spells, high evapotranspiration rates, and depleted river flows.

### Body Paragraph 2: The Impact of Human Factors on Hydrological Systems
- Argue that human activities directly convert a standard meteorological drought into a severe hydrological crisis.
- Over-abstraction: In places like the Central Valley of California or the Indo-Gangetic Plain, massive groundwater extraction for agriculture lowers water tables rapidly, meaning even normal rainfall cannot easily replenish depleted aquifers.
- Land-use change (Deforestation and Urbanisation): Deforestation in the Amazon reduces evapotranspiration and regional precipitation recycling, which permanently alters the hydrological cycle and streamflow.
- Reservoir construction and management: Upstream damming (e.g., the Grand Ethiopian Renaissance Dam or dams on the Mekong) physically disrupts downstream flows, causing artificial hydrological drought for downstream nations.

### Body Paragraph 3: The Interconnection and Synthesis
- Argue that physical factors are the critical *trigger* of drought, but human factors determine the *vulnerability* and *severity* of the hydrological response.
- For instance, in the Sahel, natural climatic desiccation (physical) was historically manageable, but rapid population growth, overgrazing, and deforestation (human) degraded soils, reduced infiltration, and turned a rainfall deficit into a catastrophic hydrological and socio-economic disaster.
- Conversely, in well-managed catchments, human storage and planning can mitigate the effects of physical anomalies.

### Conclusion
- Conclude that physical factors remain the absolute critical trigger of drought at a global/regional scale. However, human factors are increasingly dominant at local and basin scales, transforming natural climate variability into severe and prolonged hydrological crises by permanently depleting groundwater and disrupting river systems.

First, calculate the absolute increase: \(11.7 - 4.5 = 7.2\) billion. Next, divide this increase by the original 2010 value: \(7.2 / 4.5 = 1.6\). Finally, multiply by 100 to convert to a percentage: \(1.6 \times 100 = 160\%\).

1 mark for showing correct working (e.g. \(11.7 - 4.5\) divided by 4.5, or identifying the increase of 7.2). 1 mark for the correct final answer of 160% (accept 160 or 160.0%).

Sum the GDP values for all five nations: \(30.3 + 11.8 + 4.8 + 3.8 + 4.3 = 55.0\) trillion. Divide this sum by the total number of nations (5): \(55.0 / 5 = 11.0\) trillion.

1 mark for showing correct working (summing the values to get 55.0 and dividing by 5, e.g. \(55.0 / 5\)). 1 mark for the correct final answer of $11.0 trillion (accept 11, 11.0, or 11 trillion).

Award 1 mark for each valid reason identified, and a further 1 mark for explaining/developing how this leads to social or cultural tensions, up to a maximum of 4 marks (2 x 2 marks).

- Reason 1: The rise of globalised Western culture (e.g., through fast food, media, and language) can erode local languages and traditional customs. This causes tension between younger generations who adopt modern lifestyles and older, more traditional populations who seek to preserve historic cultural practices.
- Reason 2: Rapid cultural diffusion through globalisation can provoke nationalist or anti-globalisation movements. Local communities may feel their national identity or job security is threatened by external cultural influences and global networks, leading to political tension or xenophobic backlashes.

AO1 (2 marks): Identify two reasons why cultural diffusion leads to social/cultural tensions.
AO2 (2 marks): Explain/develop both reasons, linking cultural diffusion to specific outcomes (such as generational conflict or political backlash).

Acceptable answers include:
- Loss of traditional diet leading to health concerns and anti-multinational protests.
- Spread of global consumer culture creating wealth inequalities and social resentment.
- Religious groups resisting liberal or secular Western values.

Award 1 mark for each valid soft power mechanism identified (AO1), and 1 mark for a developed explanation of how this extends global influence (AO2), up to a maximum of 6 marks (3 x 2 marks).

- Way 1: Cultural initiatives and educational outreach (e.g., China's Confucius Institutes or India's Bollywood industry). This shapes a positive, familiar national narrative, which increases diplomatic leverage and lowers resistance to economic deals.
- Way 2: Financial aid, low-interest loans, and diplomatic support (e.g., China's Belt and Road Initiative projects in developing countries). This fosters geopolitical goodwill and builds strategic dependency without requiring military coercion.
- Way 3: Hosting high-profile international mega-events (e.g., G20 summits or the Olympic Games). This showcases infrastructural and economic success on the world stage, elevating global prestige and soft diplomacy.

AO1 (3 marks): Identify three ways emerging powers leverage soft power.
AO2 (3 marks): Explain how each identified way translates into extended geopolitical or economic global influence.

Reject points focusing solely on hard military power, trade embargoes, or economic sanctions.

Award 1 mark for identifying a valid way infrastructure investment aids regeneration (AO1), and a further 1 mark for explaining how this benefits a declining urban area (AO2). Max 4 marks (2 x 2 marks).

- Way 1: Transport connectivity enhancements (e.g., high-speed rail links or new highway access). This integrates historically isolated, deprived areas into national economic hubs, prompting businesses to relocate there due to reduced travel times and costs.
- Way 2: Flagship physical developments (such as major sports arenas or technology parks). These projects act as catalysts for the cumulative causation/multiplier effect, as public sector confidence encourages secondary private investments in housing, retail, and services, driving job creation.

AO1 (2 marks): Identify two ways infrastructure leads to regeneration.
AO2 (2 marks): Explain the physical, social, or economic outcomes of this investment on urban decline.

Acceptable ideas include:
- Redeveloping brownfield sites for transit hubs.
- Boosting local tourism and retail spending through improved public realms.
- Attracting high-income workers to reverse brain drain.

Award 1 mark for each valid reason identified (AO1), and 1 mark for explaining how this hinders improvements in human rights (AO2). Max 6 marks (3 x 2 marks).

- Reason 1: Active military campaigns often result in extensive collateral damage, infrastructure destruction, and large-scale displacement of civilians. This creates immediate refugee crises where basic human rights (e.g., shelter, healthcare, safety) cannot be met.
- Reason 2: The removal of an authoritarian regime by foreign forces frequently leads to a severe political power vacuum. Without stable local governance, rival militant groups or warlords may seize power, causing lawlessness and widespread human rights violations that are worse than the original regime.
- Reason 3: Foreign intervention may be seen as illegitimate by the local population. This can trigger prolonged insurgencies and guerrilla warfare, where both sides may commit abuses and human rights are secondary to military survival.

AO1 (3 marks): Identify three reasons why military interventions fail to improve human rights.
AO2 (3 marks): Explain the mechanisms through which these interventions degrade human rights conditions.

Acceptable points can include:
- Economic sanctions accompanying intervention worsening poverty.
- Lack of long-term post-conflict reconstruction funding.
- Abuse of power by occupying or peacekeeping forces.

Award 1 mark for identifying a demographic shift caused by gentrification (AO1), and a further 1 mark for explaining the process of how gentrification produces this shift (AO2). Max 4 marks (2 x 2 marks).

- Way 1: Displacement of low-income, long-term working-class residents. As gentrification increases property values, rents, and local taxes, lower-income households are forced to relocate, and are replaced by higher-income, professional socio-economic groups.
- Way 2: A transition in the age profile of the neighborhood. Redevelopments often cater to young, single, or dual-income-no-kids (DINK) professionals who seek urban lifestyles, leading to a decline in multi-generational families and the elderly who find the area's new amenities and costs unsustainable.

AO1 (2 marks): Identify two demographic trends (e.g., changes in age, socio-economic status, or ethnicity).
AO2 (2 marks): Explain how the physical and economic processes of gentrification (e.g., rent increases, housing stock conversions) cause these changes.

Acceptable answers include changes in ethnic composition due to migration patterns and displacement.

The global shift refers to the movement of manufacturing and services from developed countries to emerging and developing economies, primarily in Asia, Latin America, and parts of Africa.

Economic Benefits:
- **FDI and Economic Growth:** Inward Foreign Direct Investment (FDI) has acted as an economic catalyst. In China, the Pearl River Delta became the 'workshop of the world,' driving GDP growth rates of around 10% annually for decades.
- **Poverty Reduction:** The global shift has lifted over 800 million people out of poverty in China alone since 1978. It has created a burgeoning middle class with disposable income, shifting economies from primary/subsistence sectors to higher-paying secondary and tertiary jobs.
- **Infrastructure and Investment:** Tax revenues and state-directed investments have funded massive infrastructure projects (high-speed rail, modern ports, energy grids), improving domestic connectivity and national wealth.
- **Skills Transfer and Technology:** Workers gain skills, and local companies benefit from technology transfer, allowing countries to move up the value chain over time.

Environmental Costs:
- **Air Pollution:** Rapid industrialisation has led to severe air pollution. Many Chinese and Indian cities frequently record PM2.5 levels far exceeding safe limits set by the WHO, causing chronic respiratory illnesses and reducing life expectancy.
- **Water Contamination:** Industrial effluents have severely polluted major river systems. For example, large portions of the Yangtze and Ganges rivers have suffered from heavy metal pollution and chemical runoff, threatening agricultural irrigation and clean drinking water access.
- **Resource Depletion and Land Degradation:** Deforestation, soil erosion, and open-cast mining to secure raw materials have degraded fragile ecosystems. Global shift often leads to 'pollution havens' where transnational corporations (TNCs) exploit weaker environmental regulations.

Evaluation/Assessment of the Extent:
While the economic benefits have successfully transformed these nations, enabling them to transition from low-income to middle-income status, the environmental costs are often severe, localized, and historically ignored in early development phases. However, the extent depends on the country's stage of development: as economies grow wealthier (e.g., China's current shift towards green energy and stricter environmental regulations), they begin to invest their economic gains back into environmental mitigation. Therefore, in the short term, environmental costs have often drastically compromised local quality of life, but in the long term, the economic benefits provide the capital and technology required to clean up and transition to sustainable development pathways.

AO1 (6 marks): Demonstrate knowledge and understanding of the global shift of manufacturing and its diverse impacts on emerging countries.
AO2 (6 marks): Apply geographical knowledge to assess whether the economic benefits outweigh the environmental costs, utilizing specific case study details (e.g., China, India, Vietnam).

Level 1 (1–3 marks):
- Demonstrates isolated knowledge of global shift with limited case study support.
- Analytical focus is weak; provides a simple list of pros and cons with little structure or evaluation.

Level 2 (4–6 marks):
- Demonstrates some accurate geographical knowledge of both economic and environmental impacts.
- Applies knowledge to evaluate benefits vs. costs, but may lack balance or specific, detailed case study evidence.

Level 3 (7–9 marks):
- Demonstrates good, detailed knowledge of global shift, using specific case study examples (e.g., Pearl River Delta, air/water pollution statistics, GDP figures).
- Explores both economic benefits (poverty reduction, infrastructure) and environmental costs (pollution, degradation) with a clear assessment of their relative significance.

Level 4 (10–12 marks):
- Demonstrates comprehensive, precise geographical knowledge of the global shift and its multifaceted consequences.
- Offers a highly sophisticated, balanced, and structured evaluation, showing how the 'extent' varies over time and space, concluding with a fully justified judgment.

Since the collapse of the Soviet Union, the USA has operated as the world's sole superpower (unipolar world). However, the rise of emerging nations, particularly China and Russia, is increasingly shifting the world toward a multipolar system.

Areas where emerging powers challenge US influence:
- **Economic Dominance:** China's rapid GDP growth has positioned it to overtake the US economy in absolute size in the coming decades. Through the Belt and Road Initiative (BRI), China has exported its economic model, investing over $1 trillion in global infrastructure, thereby securing resource access and building political alliances in Africa, Latin America, and Asia, bypassing Western-led financial systems like the IMF/World Bank.
- **Alternative Institutions:** The establishment of the Asian Infrastructure Investment Bank (AIIB) and the expansion of the BRICS block (introducing the New Development Bank) challenge the post-WWII Bretton Woods system dominated by the US and Europe.
- **Geopolitical/Military Assertiveness:** China's militarisation of artificial islands in the South China Sea directly challenges US naval supremacy ('freedom of navigation') in the Indo-Pacific. Meanwhile, Russia's aggressive actions in Eastern Europe and the Middle East challenge the Western-led security umbrella (NATO).
- **Resource Hegemony:** Emerging nations are securing key strategic resources (lithium, cobalt, rare earth minerals) vital for the future green economy, leaving Western nations vulnerable.

Areas where US dominance remains resilient:
- **Military Superiority:** Despite rising budgets elsewhere, the US military budget still exceeds the next ten nations combined. It possesses unmatched global military projection capabilities via its network of global bases and aircraft carrier strike groups.
- **Soft Power and Culture:** The USA maintains a massive advantage in soft power. Its global brands (Apple, Google), media (Hollywood, Netflix), higher education system, and political ideals of democracy and free speech remain far more globally pervasive than China's or Russia's cultural exports.
- **Financial Centrality:** The US Dollar remains the world's primary reserve currency and the foundation of global trade, giving the USA unmatched leverage via economic sanctions.

Evaluation/Assessment of the Extent:
Emerging powers pose a highly significant challenge to US economic and regional geopolitical hegemony, effectively ending the unipolar era. However, this challenge is currently regional and economic rather than absolute. The USA maintains an overwhelming global military, financial, and cultural lead. Therefore, the challenge is significant enough to create a contested, multipolar geopolitical environment, but not yet sufficient to fully displace the USA as a premier global superpower.

AO1 (6 marks): Demonstrate knowledge and understanding of superpowers, emerging powers, and their relative economic, military, political, and cultural influence.
AO2 (6 marks): Apply geographical knowledge to assess the extent to which emerging powers challenge the USA's established hegemony.

Level 1 (1–3 marks):
- Demonstrates basic, descriptive knowledge of superpowers with little focus on the specific challenge to the USA.
- Lacks structure, clear examples, or a balanced argument.

Level 2 (4–6 marks):
- Demonstrates some accurate knowledge of emerging powers (e.g., China's economic growth or Russia's military action).
- Evaluates the situation but may focus heavily on one aspect (e.g., only military or only economic) without analyzing the broader context.

Level 3 (7–9 marks):
- Demonstrates detailed knowledge of geopolitical mechanisms, including specific examples (e.g., BRI, AIIB, South China Sea, NATO, soft power comparison).
- Provides a balanced assessment of both the strengths of emerging powers and the ongoing resilience of US global hegemony.

Level 4 (10–12 marks):
- Demonstrates comprehensive, nuanced knowledge of the shifting global geopolitical landscape.
- Offers a highly sophisticated, structured evaluation, distinguishing between regional and global influence, and concludes with a clear, well-supported judgment on the 'extent' of the challenge.

AO1 Knowledge and understanding: Explains Joseph Nye's concepts of hard power (military force, economic sanctions, coercion) and soft power (cultural attraction, political values, foreign policy, diplomacy). References players like the USA, China, and Russia. Explains 'smart power'. AO2 Application and evaluation: Evaluates the limitations of relying solely on hard power (e.g., the high economic and diplomatic costs of military interventions like Iraq/Afghanistan, or the international isolation of Russia). Evaluates how soft power helps superpowers shape global norms and international institutions (e.g., US cultural influence, global brands, and aid). Evaluates the limits of soft power (e.g., China's Confucius Institutes and massive investment in soft power have struggled to offset concerns about its military expansion in the South China Sea). Synthesises these points to show that economic strength (a component of hard power) is required to fund soft power initiatives and military capability. Concludes that hard power remains the ultimate guarantor of sovereignty and global influence, but long-term hegemony requires the skillful integration of both (smart power).

Level 4 (16-20 marks): Explains with exceptional detail how soft and hard power maintain superpower status. Evaluates the relative importance of both, showing deep analytical insight. Supported by precise, relevant case studies (e.g., US, China, Russia). Formulates a highly balanced, logical conclusion. Level 3 (11-15 marks): Explains both hard and soft power clearly. Evaluates their relative importance with some structured arguments, supported by good case study details. Level 2 (6-10 marks): Describes soft and hard power but with limited evaluation of their relative importance. Case studies are general. Level 1 (1-5 marks): Shows basic knowledge of superpower power types but lacks structure and evaluation.

AO1 Knowledge and understanding: Explains the role of different players in regeneration, including local communities, national governments, local councils, and private developers. Identifies different measures of 'success' (economic growth, social cohesion, environmental improvement). AO2 Application and evaluation: Evaluates the importance of community engagement (e.g., bottom-up projects like Coin Street Community Builders in London, which prioritize social housing and community facilities, preventing gentrification). Contrasts this with top-down, developer-led schemes (e.g., London Docklands or Stratford Olympic Legacy), where lack of community engagement led to local displacement, social polarization, and accusations of gentrification, despite high economic success. Evaluates the role of other factors, such as government policy (e.g., enterprise zones, deregulation) and massive private investment, arguing that without these, large-scale infrastructural regeneration is impossible. Concludes that the definition of 'success' depends on the player's perspective, but truly sustainable, multi-dimensional success requires balancing top-down financial capability with bottom-up community engagement.

Level 4 (16-20 marks): Demonstrates comprehensive understanding of the players and conflicting views of regeneration success. Evaluates the relative role of community engagement with sophisticated analysis. Supported by precise case studies. Reaches a clear, balanced conclusion. Level 3 (11-15 marks): Shows good understanding of community roles and other factors in regeneration. Evaluates success criteria with structured arguments and relevant case studies. Level 2 (6-10 marks): Descriptive account of regeneration schemes with limited evaluation of community engagement versus other players. Level 1 (1-5 marks): Basic description of regeneration with little or no evaluation of success factors.

An Exclusive Economic Zone (EEZ) is an area of the ocean, prescribed by the United Nations Convention on the Law of the Sea (UNCLOS), extending up to 200 nautical miles from a nation's baseline. Within this zone, the coastal state has sole exploitation rights over all natural resources, including fisheries, minerals, and wind/wave energy.

For Small Island Developing States (SIDS), which possess small land masses but vast ocean territories, the EEZ is critical for sustainable development:
1. Economic diversification and revenue: SIDS can license fishing rights to foreign vessels or develop domestic sustainable fisheries, providing crucial GDP growth and funding for public services.
2. Conservation and Ecotourism: They can establish Marine Protected Areas (MPAs) within their EEZ to conserve biodiversity, attracting high-value sustainable ecotourism while protecting vital coastal ecosystems like coral reefs from destructive overfishing.

Award up to 2 marks for the definition of an Exclusive Economic Zone (EEZ):
- 1 mark for identifying that it is a marine area extending up to 200 nautical miles from the coast/baseline.
- 1 mark for explaining that the coastal state has sovereign/exclusive rights over the exploration, exploitation, conservation, and management of resources (living and non-living) within this area.

Award up to 2 marks for explaining how it supports the sustainable development of SIDS:
- 1 mark for identifying a specific sustainable marine opportunity (e.g., sustainable fisheries management, offshore renewable energy, marine ecotourism, or blue carbon initiatives).
- 1 mark for linking this opportunity to long-term economic, social, or environmental development/resilience (e.g., generating national revenue to invest in climate adaptation, or protecting marine biodiversity to secure future food sources and ecotourism income).

To calculate the Spearman's rank correlation coefficient:

1. Identify the variables: \(n = 6\) and \(\sum d^2 = 14\).
2. Substitute the values into the formula:
\[r_s = 1 - \frac{6 \times 14}{6(6^2 - 1)}\]
3. Calculate the numerator:
\[6 \times 14 = 84\]
4. Calculate the denominator:
\[6 \times (36 - 1) = 6 \times 35 = 210\]
5. Complete the division:
\[\frac{84}{210} = 0.4\]
6. Subtract from 1:
\[r_s = 1 - 0.4 = 0.60\]

Award marks as follows:
- **1 mark** (Method): Correct substitution of values into the Spearman's rank formula, showing \(r_s = 1 - \frac{6 \times 14}{6 \times 35}\) or \(1 - \frac{84}{210}\).
- **1 mark** (Accuracy): Correct calculation of the fraction as \(0.4\) or the intermediate step showing the subtraction.
- **0.67 marks** (Accuracy): Correct final coefficient of \(0.60\) (accept \(0.6\)).

To calculate the Location Quotient (LQ):

1. Calculate the local tourism ratio (Vanuatu):
\[e_i / e = \frac{18,000}{60,000} = 0.30\]
2. Calculate the global tourism ratio:
\[E_i / E = \frac{330,000,000}{3,300,000,000} = 0.10\]
3. Divide the local ratio by the global ratio:
\[LQ = \frac{0.30}{0.10} = 3.0\]

Award marks as follows:
- **1 mark** (Method): Correct calculation of the local employment ratio (\(0.30\) or \(30\%\)) or the global employment ratio (\(0.10\) or \(10\%\)).
- **1 mark** (Method): Correct setting up of the ratio-of-ratios division (e.g., \(\frac{0.30}{0.10}\)).
- **0.67 marks** (Accuracy): Correct final answer of \(3.0\) (accept \(3\)).

To calculate the overall weighted vulnerability score, multiply each indicator score by its respective weight, and then sum the values:

1. Sea Level Rise contribution:
\[9.2 \times 0.45 = 4.14\]
2. Economic Shock contribution:
\[6.4 \times 0.35 = 2.24\]
3. Freshwater Scarcity contribution:
\[5.0 \times 0.20 = 1.00\]
4. Sum the weighted contributions:
\[4.14 + 2.24 + 1.00 = 7.38\]

Award marks as follows:
- **1 mark** (Method): Evidence of multiplying scores by weights for at least two variables (e.g., showing \(9.2 \times 0.45 = 4.14\) and \(6.4 \times 0.35 = 2.24\)).
- **1 mark** (Method): Summing all three correctly computed weighted scores (\(4.14 + 2.24 + 1.00\)).
- **0.67 marks** (Accuracy): Correct final score of \(7.38\).

AO3 (4 marks): Candidates should analyse the table to identify key trends and anomalies. There is a general positive correlation between economic damage from tropical cyclones and reliance on ODA (e.g., Tuvalu has high damage at \(50\) percent of GDP and the highest ODA at \(38.5\) percent of GNI, while Fiji has lower damage at \(20\) percent and low ODA at \(4.1\) percent). However, Dominica is an extreme anomaly where economic damage vastly exceeds ODA (damage of \(220\) percent of GDP compared to \(15.4\) percent ODA), showing that international aid does not scale linearly to catastrophic losses. AO2 (4 marks): Candidates should apply their understanding of SIDS vulnerability and geopolitical players. SIDS are structurally vulnerable due to small domestic markets, remote locations, and narrow revenue bases, making independent recovery from severe hydrometeorological events impossible. This forces heavy reliance on external players (bilateral donors, UN agencies) for financial survival. The mismatch in countries like Dominica highlights the limitations of international aid frameworks, forcing governments into unsustainable external debt to rebuild basic infrastructure.

Level 1 (1-3 marks): Demonstrates isolated elements of geographical knowledge and understanding. Analysis of the data is descriptive and lacks synthesis. Explanations of vulnerability are basic. Level 2 (4-6 marks): Demonstrates clear geographical knowledge and understanding. Applies knowledge to explain the link between hazard impacts and aid dependency. Analysis of the table identifies general trends and makes some connections between variables. Level 3 (7-8 marks): Demonstrates precise and comprehensive geographical knowledge and understanding. Evaluates the data critically, identifying both positive correlations and key anomalies (such as Dominica). Synthesises geographical concepts of vulnerability, scale of impact, and international aid limitations to provide a fully reasoned analytical response.

AO3 (4 marks): Candidates should analyse Table 2 to connect high debt levels with lagging progress toward renewable energy goals. All four SIDS face high debt-to-GDP ratios exceeding \(80\) percent, with Maldives the highest at \(115\) percent. Maldives also has a significant gap to close, currently at only \(8\) percent of its \(20\) percent target. Mauritius has an ambitious \(60\) percent target but has only achieved \(22\) percent despite its \(102\) percent debt load. Candidates should note that high debt correlates with slow transition progress due to restricted fiscal space. AO2 (4 marks): Candidates should apply concepts of sustainable development, financial barriers, and player influence. High national debt requires substantial interest payments, which crowds out public capital investment required for expensive renewable infrastructures (solar fields, offshore wind, battery storage grids). SIDS lack economies of scale, making initial capital expenditure (CapEx) for green energy disproportionately expensive. International financial institutions (such as the IMF) often impose austerity measures on highly indebted nations, further restricting environmental spending. This creates a cycle where SIDS remain locked into importing expensive fossil fuels, compounding their economic vulnerability.

Level 1 (1-3 marks): Explains barriers to sustainable energy in a generic way. Minimal use of the data, perhaps only quoting individual figures without analysis. Limited geographical understanding of why debt restricts investment. Level 2 (4-6 marks): Shows clear understanding of how debt restricts government spending. Analytical use of the data to compare different SIDS and their progress towards targets. Explains the connection between high capital costs of green energy and national debt. Level 3 (7-8 marks): Detailed and nuanced analysis of the data, highlighting the fiscal constraints of all four nations. Applies advanced geographical understanding of systemic financial barriers, the role of international players (IMF/lenders), structural vulnerabilities of SIDS, and how debt servicing locks countries into unsustainable fossil fuel dependencies.

### Introduction
Small Island Developing States (SIDS) face a unique convergence of vulnerabilities, including physical isolation, fragile ecosystems, high economic openness, and severe susceptibility to climate change hazards (such as sea-level rise and intensified tropical cyclones). While some argue that SIDS have negligible global agency and depend entirely on global players (high-emitting superpowers, international financial institutions, and UN agencies) for their long-term survival, others emphasize that localized, culturally embedded, and ecologically sensitive adaptation strategies are critical to securing sustainable futures.

### Arguments Supporting Dependency on Global Players
1. **The Global Mitigation Mandate:** SIDS collectively contribute less than 1% of global greenhouse gas emissions, yet bear the brunt of climate impacts. No amount of local adaptation can withstand a global temperature rise exceeding \(2.0^\circ\text{C}\) (which could submerge low-lying atolls like Tuvalu, Kiribati, and the Maldives). Therefore, their environmental sustainability is structurally dependent on superpowers (USA, China, EU) fulfilling their emissions reductions under the Paris Agreement.
2. **Financial Dependency:** Capital-intensive hard engineering (e.g., seawalls in Male) and complex infrastructural transformations (e.g., utility-scale solar arrays, desalination plants) cannot be financed by SIDS' limited tax bases. They require international players, such as the Green Climate Fund (GCF), World Bank, and bilateral donors, to bridge the massive climate finance gap.
3. **Economic Sovereign Relief:** Global players determine economic sustainability through trade agreements, maritime boundaries, and tourism flows. Post-disaster recovery heavily relies on international aid and debt-relief packages.

### Arguments Supporting the Vital Role of Local Adaptation Strategies
1. **Context-Specific Resilience:** Centrally planned, top-down projects funded by global players often suffer from 'maladaptation' (e.g., concrete seawalls disrupting natural sediment transport and destroying coral reefs). In contrast, local, ecosystem-based adaptation (EbA)—such as community-managed mangrove restoration and coral farming—offers low-cost, self-sustaining coastal defense that supports local biodiversity and fisheries.
2. **Traditional Ecological Knowledge (TEK):** Indigenous farming and water-harvesting practices (e.g., rain-fed taro pits, traditional water storage) are often more resilient to climate shocks than modern imports. Local agency ensures community buy-in, which is vital for long-term project viability.
3. **Decentralised Renewable Energy:** Transitioning to distributed off-grid solar and biomass projects managed by local cooperatives reduces dependence on expensive imported fossil fuels, driving localized economic sustainability.

### Synoptic Synthesis and Evaluation
A balanced perspective reveals that economic and environmental sustainability is not a binary choice but a nested dependency. Local strategies provide immediate resilience, livelihood security, and cultural continuity. However, they operate within strict physical limits. If global players fail to limit warming or default on climate finance commitments, local adaptation will reach its ecological thresholds, forcing displacement and sovereign loss. Conversely, without active local community co-design, global financial injections fail to yield sustainable results, leading to wasted capital and dependency traps.

### Conclusion
Ultimately, while local adaptation strategies are indispensable for day-to-day resilience and the preservation of SIDS communities, their absolute long-term survival remains fundamentally contingent upon the attitudes and actions of global players. SIDS can adapt to the symptoms of global environmental and economic shifts locally, but the causes can only be mitigated globally.

**Marking Criteria (Total: 21 Marks)**

- **Level 1 (1-5 Marks):** Demonstrates isolated and descriptive knowledge of SIDS, climate change, or globalisation. Lacks clear synoptic links. Focuses heavily on generic environmental impacts without assessing the role of specific players or adaptation strategies. Assessment of the question is superficial and lacks structure.
- **Level 2 (6-10 Marks):** Outlines some impacts of global players (e.g., emissions, aid) and local strategies. Shows basic understanding of synoptic connections (e.g., linking climate change to economic vulnerability). The evaluation is present but tends to be unbalanced or largely descriptive rather than critical.
- **Level 3 (11-15 Marks):** Explains a range of physical and human interactions affecting SIDS sustainability (e.g., coastal processes, global trade, aid dependency). Good synoptic integration of Paper 1 (coastal/carbon/water cycles) and Paper 2/3 themes (globalisation, players, futures). Evaluates both global and local levels with clear structure and relevant examples.
- **Level 4 (16-21 Marks):** Formulates a highly sophisticated, balanced, and nuanced synoptic evaluation. Integrates precise case-study details (e.g., Kiribati, Maldives, Caribbean SIDS). Clearly distinguishes between short-term local resilience and long-term existential survival dictated by global emissions. Synthesises physical limitations, economic realities, and geopolitical power dynamics into a coherent, structured argument ending in a logical and justified conclusion.

### Introduction
Small Island Developing States (SIDS) are highly vulnerable to energy and water insecurity due to isolation, reliance on imported petroleum, and fragile hydrological systems (e.g., thin freshwater lenses threatened by saltwater intrusion and over-extraction). Resolving these issues requires immense capital and technological intervention. In recent years, the geopolitical rivalry between established superpowers (such as the USA, EU, and Australia) and emerging powers (specifically China) has intensified in regions like the South Pacific and the Caribbean, presenting SIDS with complex trade-offs between developmental opportunities and geopolitical risks.

### Opportunities of Geopolitical Rivalry
1. **Alternative Financing & Infrastructural Boom:** The competition for diplomatic influence has unlocked unprecedented access to capital. China's Belt and Road Initiative (BRI) has funded vital infrastructure, such as port developments, solar energy grids, and roads. In response, western allies have launched rival initiatives, such as the US-Japan-Australia partnership, providing SIDS with leverage to negotiate favorable aid packages.
2. **Accelerated Desalination and Renewable Energy Projects:** Competitors are eager to showcase technological prowess. For example, bilateral agreements have facilitated the installation of advanced seawater reverse osmosis (SWRO) desalination plants and micro-grids, accelerating SIDS' transition away from fossil-fuel dependence and enhancing water security.
3. **Diplomatic Leverage:** SIDS can utilize their strategic geopolitical location (and their votes in international forums like the UN) to extract concessions, aid, and technology transfers from both sides without aligning exclusively with one power.

### Risks of Geopolitical Rivalry
1. **Debt-Trap Diplomacy & Sovereignty Risks:** A significant risk is the accumulation of unsustainable bilateral debt. If SIDS default on infrastructure loans, they risk losing control of sovereign strategic assets (e.g., deep-water ports), compromising their long-term economic independence.
2. **Maladaptation and Inappropriate Technologies:** Geopolitically driven aid often prioritizes high-profile, high-tech installations (e.g., massive desalination plants) over culturally or ecologically appropriate systems. These systems are prone to failure due to a lack of local technical capacity and the high cost of imported replacement parts, leading to eventual abandonment.
3. **Strategic Militarisation and Domestic Instability:** Rivalry can split domestic political factions within SIDS (some pro-Beijing, others pro-Washington/Canberra), causing political instability and diverting governance away from long-term sustainable resource management.

### Synoptic Synthesis and Evaluation
To synoptically evaluate this issue, we must connect the physical limitations of SIDS (such as their vulnerable hydrological cycles and high solar/wind potential) with human geopolitical systems. While the 'geopolitical bidding war' has undoubtedly fast-tracked investments that would have otherwise taken decades to secure through slow-moving multilateral channels, the risks are highly uneven. SIDS with robust democratic institutions and strategic foresight can successfully navigate the rivalry to build resilient utilities. In contrast, fragile states face a high probability of entering debt cycles and suffering from poorly executed, unsustainable infrastructure.

### Conclusion
In conclusion, geopolitical rivalry offers substantial short-term developmental opportunities for SIDS trying to resolve their energy and water insecurity. However, the associated risks of sovereignty loss, debt distress, and technology mismatch are immense. Over the long term, the opportunities outweigh the risks only if SIDS can maintain strong domestic governance, refuse exploitative debt structures, and ensure that foreign-funded infrastructure aligns with local environmental realities rather than external geopolitical interests.

**Marking Criteria (Total: 21 Marks)**

- **Level 1 (1-5 Marks):** Simple, descriptive accounts of either water/energy insecurity or global politics. Outlines very general ideas of aid or China's influence with limited geographic detail. Synoptic links are absent or highly generalized.
- **Level 2 (6-10 Marks):** Describes how superpowers invest in SIDS (e.g., building roads or solar power) and the challenges of water scarcity.
