Social Science (087) — AI-generated practice question

The north-eastern region has high relief, dense forests, numerous river channels, and swampy/hilly terrain, making road and rail construction extremely difficult and costly. The Himalayan ranges and frequent landslides further add to the challenge.

Airways provide the fastest connectivity over this rugged terrain, bypassing physical barriers entirely. Inland waterways, especially the Brahmaputra river (NW No. 2, Sadiya to Dhubri — 891 km), serve as a natural, cheap, and eco-friendly route for carrying heavy goods across this riverine landscape, supplementing road and rail effectively.

• The answer links terrain factors (high relief, forests, rivers, swamps) to construction difficulty — this is the first part examiners look for.
• Then it addresses both airways and inland waterways separately, as the question specifically asks for both — never club them together.
• Citing NW No. 2 (Brahmaputra) shows precise textbook knowledge and earns extra credit.
• At 3 marks, keep it to 3 clear points — no lengthy elaboration needed.
