Read the following excerpt from paragraph 3:

"Traditional urban landscaping heavily prioritised manicured lawns and non-native ornamental blooms, which demand vast quantities of chemical fertilisers and regular mowing. In contrast, ecological rewilding adopts a deliberate policy of benign neglect. By allowing native shrubs and wildflowers to flourish unimpeded along highway verges and rooftop gardens, city planners can create resilient ecological corridors. These micro-habitats not only attract vital pollinators such as bumblebees and hoverflies, but they also reduce maintenance expenses drastically."

Complete the summary of paragraph 3 below by writing ONE word taken from paragraph 3 in the blank. Your answer must be grammatically correct.

Summary:
Unlike conventional landscaping, urban rewilding leaves native vegetation to grow without human interference. This approach successfully establishes interconnected natural routes termed ecological (i) ____________, which support pollinators while lowering upkeep costs.

Read the following excerpt from paragraph 4:

"Despite these evident ecological perks, public perception remains an obstacle. Many urbanites initially perceive uncultivated plots as neglected eyesores rather than biodiverse sanctuaries, occasionally lodging complaints about overgrown weeds. To combat this resistance, municipalities have introduced 'cues to care'—neatly mown perimeter borders, aesthetic wooden fences, and explanatory signage that clarify the ecological intention behind the wild vegetation."

Complete the summary of paragraph 4 below by writing ONE word taken from paragraph 4 in the blank. Your answer must be grammatically correct.

Summary:
To overcome residents' negative reactions and counteract public (i) ____________ toward untamed flora, local authorities have added decorative fences and informative signs highlighting the purpose of rewilded sites.

Find a word in paragraph 3 that has a similar meaning to 'gathering together into a single whole or system'.

Read the following extract from paragraph 5 of Text 4:

"Algorithmic curation does not merely cater to preexisting tastes; it progressively narrows the user's intellectual horizon, creating ideological echo chambers that insulate individuals from dissenting viewpoints."

According to paragraph 5, how do echo chambers affect an individual's exposure to differing opinions?

Read the following extract from paragraph 7 of Text 4:

"The town council’s pilot initiative to replace synthetic turf with biodiverse micro-forests was initially met with fierce scepticism by local sports clubs, who feared the loss of recreational amenities. However, when ambient summer temperatures dropped by over three degrees Celsius in adjacent residential streets, community resistance evaporated."

According to paragraph 7, what caused the local community to stop resisting the micro-forest initiative?

Read the excerpt from Text 4 below and answer the question.

Paragraph 3: While municipal planners historically favoured manicured turf and non-native ornamental shrubs for their aesthetic predictability, the severe heatwaves of recent summers have prompted a radical rethink. Proponents of 'micro-forests' argue that dense, hyper-local woodlands not only lower ambient temperatures through evapotranspiration but also serve as vital conduits for endangered urban fauna.

According to paragraph 3, what made municipal planners prefer manicured turf and ornamental shrubs in the past?

Text 4 (paragraphs 4–6)
Paragraph 4: Coastal estuaries across the hemisphere have long suffered from severe sediment smothering, where fine silt loaded with chemical pollutants settles onto marine flora, suffocating native seagrass meadows. Traditional dredging operations proved prohibitively expensive and frequently exacerbated the dispersal of toxic particulates into offshore feeding grounds.
Paragraph 5: To overcome these obstacles, marine ecologists developed modular bio-filtration grids constructed from porous volcanic aggregate. These submerged lattices not only physically intercept industrial residue before it enters sensitive nursery zones, but also host colonies of indigenous bio-degrading microbes that neutralise hazardous hydrocarbons.
Paragraph 6: Recent assessments indicate that this non-invasive intervention has successfully reversed habitat degradation. Most notably, the restored water clarity has triggered a rapid resurgence of macroalgae beds, providing crucial shelter for vulnerable juvenile crustaceans and revitalising local fisheries.

AUDIO TRANSCRIPT (for reference):
Rachel: Welcome back to Nature Matters. Today, we're joined by Dr. Derek Fong from the Urban Wildlife Rescue Initiative. Derek, tell us about the primary objectives of the initiative.
Dr. Derek Fong: Hi Rachel. Well, our main mission is twofold: first, to rescue injured stray native species like the Eurasian otter and masked palm civet, and second, to conduct educational outreach in suburban housing estates.
Rachel: That sounds vital. What challenges do you encounter most often during rescue operations in built-up areas?
Dr. Derek Fong: Traffic collisions are by far the leading cause of trauma. In addition, secondary poisoning from unregulated rat baits poses a massive threat to nocturnal predators.
Rachel: When members of the public come across a wounded animal, what immediate steps should they follow?
Dr. Derek Fong: First, maintain a safe distance of at least five metres. Second, avoid feeding the animal any food or dairy products, as this can trigger acute shock. Third, immediately phone our 24-hour hotline at 8122-9090 with the exact GPS coordinates or nearby lamppost number.
Rachel: And what rehabilitation protocols take place at your rescue centre before release?
Dr. Derek Fong: Every admitted animal undergoes three stages: an initial surgical assessment, physical conditioning in open-air flight or prowl enclosures, and finally, a microchipping procedure so our field team can track post-release migration for up to 18 months.

AUDIO TRANSCRIPT (for reference):
Keith Vance: Good afternoon, everyone. As schools integrate generative AI tools into coursework, clear institutional guidelines are essential. Today, I want to highlight three core areas: acceptable classroom applications, ethical pitfalls, and verification techniques.

First, regarding appropriate usage: generative AI shines as an interactive brainstorming partner for idea ideation. Students can also utilise it to obtain immediate grammar debugging and to generate diverse practice quiz prompts tailored to their learning pace.

However, several major risks must be managed. The most pervasive issue is algorithmic hallucination, where tools fabricate non-existent citations. There is also a serious threat of cognitive deskilling, which happens when learners bypass active writing and critical reasoning entirely. Furthermore, data privacy compromises occur whenever students upload confidential personal data or unpublished school research.

Finally, how should educators verify authenticity? Instructors should require students to submit prompt history logs alongside essays, schedule short oral defense vivas for randomly sampled submissions, and deploy multi-layered stylometric comparison rather than relying purely on probabilistic AI detectors, which often yield false positives.

Part A Task 3

You are Kevin, a student reporter for the school newsletter. You are listening to an interview with Clara Lin, a 19-year-old innovator who won the Global Eco-Pioneer Award for her floating solar-powered marine waste collector, 'OceanSieve'. Complete the fact sheet below.

---
AUDIO TRANSCRIPT (for reference):
Interviewer: Clara, congratulations on winning the Global Eco-Pioneer Award! What sparked the concept for OceanSieve?
Clara Lin: Thank you! It started during a beach clean-up in Sai Kung back in 2023. I noticed that conventional cleaning boats were burning diesel fuel and generating heavy carbon emissions while trying to collect plastic. I thought there had to be a zero-emission alternative.
Interviewer: How does OceanSieve operate autonomously on the water?
Clara Lin: It uses a dual-hull catamaran design equipped with high-efficiency monocrystalline solar panels. These power two brushless thrusters. As it glides through coastal waters, a conveyor belt made from recycled nylon mesh scoops up floating debris. An onboard camera with computer vision identifies and sorts items into separate compartments for PET bottles, microplastic fragments, and aluminium cans.
Interviewer: What makes it safe for local marine wildlife?
Clara Lin: That was our top priority. We integrated an acoustic deterrent sensor that emits low-frequency ultrasound pulses. It gently guides fish and marine turtles away from the collection mouth. Moreover, our maximum intake speed is limited to 1.2 knots, ensuring no creature gets trapped.
Interviewer: What are your deployment targets for the upcoming year?
Clara Lin: With support from our seed investors, we are manufacturing eight commercial units by November. Our primary goal is deploying them across three busy fishing harbours in Tuen Mun, Aberdeen, and Tai O to capture an estimated 45 tonnes of marine litter annually.

### Part A, Task 1 (13 marks)

Situation:
You are Kevin, a student member of the Environmental Action Committee at St. Jude's College. You are listening to a podcast episode featuring an interview between the host, Sharon Cheung, and an environmental engineer, Dr Julian Vance, discussing the 'Cool Roofs and Microgrid Scheme' in Hong Kong.

Listen to the recording and complete the notes below. You may write in bullet points or short phrases where appropriate.

---

#### [RECORDING SCRIPT]
(Sharon Cheung: Host | Dr Julian Vance: Environmental Engineer)

Sharon: Welcome back to Urban Horizons. Today we're joined by Dr Julian Vance from the Institute of Sustainable Infrastructure. Dr Vance, urban heat islands have become a pressing issue in high-density areas. Can you explain the core concept behind the new 'Cool Roofs' initiative?

Dr Vance: Thank you, Sharon. At its simplest, a 'Cool Roof' involves applying a specialised elastomeric coating containing titanium dioxide nanoparticles onto conventional flat concrete rooftops. Traditional dark asphalt or bare concrete surfaces absorb up to 90% of solar radiation, heating indoor top floors and driving up air conditioning demands. In contrast, our coated surfaces achieve a solar reflectance rating of at least 82%, effectively bouncing sunlight away.

Sharon: What are the immediate thermal and economic outcomes observed in the pilot buildings in Kwun Tong?

Dr Vance: In the three industrial blocks we retrofitted last autumn, rooftop surface temperatures dropped by an average of 14.5 degrees Celsius during peak afternoon hours. More importantly for building managers, the reduction in thermal transfer cut indoor air conditioning energy usage by 18 percent over a four-month period. That translated into a collective electricity bill saving of around 62,000 Hong Kong dollars for each block.

Sharon: That's impressive. But the scheme isn't just about reflective paint, is it? You've integrated it with a localised microgrid system.

Dr Vance: Precisely. Alongside the reflective coating, we installed bifacial photovoltaic solar panels elevated two metres above the surface. Because the roof reflects sunlight upward from beneath, these panels generate electricity from both sides, boosting solar generation efficiency by 22% compared to standard single-sided arrays. This clean energy is stored in centralised lithium-iron-phosphate battery units located in the building's basement.

Sharon: How is the stored power utilised during peak demand?

Dr Vance: It powers two critical communal amenities: first, the corridor LED lighting networks, and second, the secondary water pumping stations during high-tariff evening hours. This completely off-sets grid reliance during peak rate windows.

Sharon: What are the principal maintenance requirements and longevity of such an installation?

Dr Vance: The coating requires a low-pressure water jet cleaning once every six months to prevent dust accumulation from degrading reflectivity. With regular inspections, the coating layer lasts roughly 10 years before requiring a recoat, while the photovoltaic panels carry an operational lifespan of 25 years.

Sharon: What advice do you have for residential estates considering adopting this scheme?

Dr Vance: First, always conduct a structural load assessment to ensure the rooftop can bear the mounting frames. Second, verify whether the estate qualifies for the government's Green Building Modernisation Subsidy, which can cover up to 40% of the initial capital expenditure.

Write an educational article titled 'Living in Harmony with Northwood's Urban Wildlife' informing local residents about common native wildlife species (such as the masked palm civet and black-crowned night heron), their ecological importance, and practical guidelines on how residents should react when encountering them.

Read the Data File below and write the article in about 220–280 words:

[Data File Extract 1 - Factsheet on Local Species]
- Masked Palm Civet: Nocturnal mammal; feeds on native fruits and insects; acts as an indispensable seed disperser for local secondary woodland regeneration; often seen on rooftops/canopies.
- Black-Crowned Night Heron: Wetland and coastal bird; nests along stream corridors; controls rodent and invasive fish populations.

[Data File Extract 2 - Interview with Wildlife Biologist Dr Vance]
'Human-wildlife conflict occurs mostly due to inappropriate human behaviour. Residents should observe the 3 'No's: (1) Never feed wildlife—it disrupts natural foraging instincts and causes nutritional imbalances; (2) Never approach or corner them for photography, especially mother animals with offspring, to avoid defensive bites; (3) Never use open poison baits for pest control, as secondary poisoning kills non-target predators like civets and raptors. Instead, secure household rubbish bins with latch lids and keep domestic dogs on leashes during evening walks.'

Write the feature article using an informative, engaging, and accessible tone.

Situation:
You are Chris Wong, Assistant Project Officer at GreenRoots Urban Ecology Foundation. Dr Evelyn Vance has instructed you to draft an evaluation report and proposal for the Board of Directors concerning the expansion of the Northwood Wildlife Rehabilitation and Rescue Clinic.

Task 10: Evaluation Report & Proposal
Write an evaluation report and proposal for the Board of Directors reviewing the clinic's first-year performance, identifying existing operational bottlenecks, and recommending two strategic resource allocations for the upcoming fiscal year.

Read the Data File below and write the report and proposal in about 250–300 words:

[Data File Extract 1 - Annual Operations Summary]
- Total wildlife rescue cases handled: 642 animals (42% increase compared to projection).
- Successful rehabilitation and release rate: 71%.
- Current facilities: 1 surgical suite, 4 quarantine holding pens, 2 full-time veterinary surgeons.

[Data File Extract 2 - Veterinary Team Feedback & Bottlenecks]
- Bottleneck A (Quarantine Capacity): Quarantine pens operate at 160% capacity during migratory bird seasons. High risk of cross-infection among injured raptors and wading birds.
- Bottleneck B (Diagnostic Equipment): The lack of an in-house digital X-ray machine forces staff to transport critically injured wildlife to private veterinary hospitals 15 km away, delaying emergency triage and causing transport stress.

[Data File Extract 3 - Proposed Solutions and Budget Estimates]
- Recommendation 1: Modular Isolation Enclosures — Add 6 modular aviaries with climate control (Estimated cost: $180,000; Construction time: 6 weeks). Resolves overcrowding and prevents avian pathogen spread.
- Recommendation 2: Procure In-house Portable Digital Radiography (DR) Unit (Estimated cost: $240,000). Eliminates transit time for trauma cases, raising surgical survival rates by an estimated 18%.

Write the report and proposal using formal reporting conventions.

PART A: GROUP DISCUSSION (8 minutes)

Read the following excerpt from a local youth survey report on screen time:

'A recent survey conducted by the Hong Kong Youth Wellness Association revealed that over 78% of secondary school students spend more than six hours daily on their smartphones outside of school hours. Many respondents cited social media browsing, mobile gaming, and instant messaging as their primary activities. Psychologists have raised concerns over deteriorating sleep quality, diminished attention spans, and reduced face-to-face social interactions among teenagers. In response, educators are exploring school-based initiatives to promote healthier digital habits.'

Your school's Student Union is planning to organize a 'Digital Wellbeing & Screen-Free Challenge Week' to encourage students to develop balanced online habits. You and your committee members are meeting to discuss the details of the campaign.

You may discuss the following:
- The major challenges students might face when reducing screen time and how to overcome them
- Activities or workshops to include during the week (e.g., unplugged hobby workshops, mindfulness sessions, outdoor challenges)
- Ways to promote the campaign and motivate students to participate actively
- Anything else you think is relevant

----------------------------------------

PART B: INDIVIDUAL RESPONSE (1 minute)

The examiner will ask you ONE question based on the topic. Examples of questions include:
1. Do you think schools should completely ban the use of mobile phones during recess and lunch? Why or why not?
2. What is the most effective way for teenagers to manage their time between schoolwork and digital entertainment?
3. Some people believe social media does more harm than good for teenage friendships. What is your opinion?
4. How can parents set a good example for their children regarding smartphone usage?

PART A: GROUP DISCUSSION (8 minutes)

Read the following extract from an editorial on wildlife conservation and stray animal welfare:

'In recent years, encounters between urban communities and local wildlife, such as feral cattle, boars, and stray domestic animals, have risen significantly. While some residents view these animals as a nuisance that poses hygiene and safety hazards, animal welfare advocates argue that urban encroachment on natural habitats is to blame. They emphasize the necessity of humane population control, public education against illegal feeding, and fostering peaceful coexistence between humans and animals.'

Your school's Community Service Club is organizing an 'Urban Wildlife and Animal Welfare Awareness Month'. You and your committee members are meeting to plan the campaign.

You may discuss the following:
- The key animal welfare and urban wildlife issues that secondary students should learn about
- Educational and hands-on activities to organize for students and the local neighborhood
- How to partner with local animal shelters and conservation non-governmental organizations (NGOs)
- Anything else you think is relevant

----------------------------------------

PART B: INDIVIDUAL RESPONSE (1 minute)

The examiner will ask you ONE question based on the topic. Examples of questions include:
1. Why do you think some people abandon their domestic pets?
2. Do you agree that feeding wild animals should be strictly penalized by law? Why or why not?
3. What qualities make a person a responsible pet owner?
4. How can schools encourage students to show greater empathy towards animals?
