RAS question
Hyperloop transportation technology proposes to move passengers:
Correct answer: (C) In pods through near-vacuum tubes at very high speeds.
Hyperloop transportation proposes to move passengers in pods through near-vacuum tubes at very high speeds.
Explanation
Hyperloop is not an air, water, or ocean-rail system; it is a tube-and-pod transport concept. Passenger or cargo pods would move through low-pressure tubes at speeds exceeding 1000 km/h, with magnetic levitation and electric propulsion used to minimise friction. NASA's NTRS record for the Hyperloop feasibility study supports the same core mechanism: a passenger pod travels through a tube under light vacuum while being propelled and levitated by permanent and electro-magnets. The low-pressure tube matters because it reduces aerodynamic drag, while levitation and propulsion keep the pod moving without the conventional wheel-on-rail contact implied by older transport systems.
Why the other options are wrong
- (A) Hot air balloons are airborne craft, whereas Hyperloop is described as a ground-based tube system carrying pods through low-pressure or light-vacuum tubes.
- (B) Water-filled tunnels reverse the key design idea: Hyperloop uses low-pressure or near-vacuum tubes to reduce resistance, not water-filled underground passages.
- (D) Magnetic levitation is part of the concept, but the pod operates inside above-ground or underground tubes, not on magnetic rails in the ocean.
Concept
This tests emerging transport technology under Science and Technology, especially how design choices reduce friction and drag. RAS often asks such concepts because they connect current innovation with basic physics and infrastructure awareness.
