解題
Satellite internet overcomes several key spatial challenges:
1. Terrain difficulties: Traditional wired infrastructure (fiber-optic or copper) requires physically digging trenches and laying cables. In mountainous, rocky, or heavily forested areas, this is often physically impossible or extremely expensive.
2. Geographic isolation / Distance: Remote communities are often located far away from central network nodes or metropolitan areas. Satellites broadcast signals from orbit, bypassing the need for continuous physical connections over vast distances.

評分準則
Award [1 mark] for each valid geographical or physical challenge identified, up to a maximum of [2 marks].
Suitable answers include:
- Physical barriers of terrain (e.g. mountains, cliffs, dense forests, or bodies of water) that prevent the trenching of cables.
- Geographic distance / remoteness from existing telecommunication backbones or urban centers.
- High susceptibility of physical ground cables to localized physical disruptions (e.g., landslides, earthquakes in mountain regions) which satellite beams bypass.
Do not award marks for general socioeconomic challenges (e.g., poverty, lack of digital literacy) as the question specifically asks for geographical or physical challenges.
