Choose the correct alternative:
Food : Stomach :: Fuel : ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Engine
The pair links a source of energy with the part where it is used up: food is digested in the stomach, and fuel is burnt in the engine to give power.
Why the other options are incorrect
Option (1) Truck — Incorrect. A truck is the whole vehicle, like the whole body, not the part that burns the fuel.
Option (3) Automobile — Incorrect. An automobile is again the whole vehicle that carries the engine.
Option (4) Plane — Incorrect. A plane is a whole vehicle too; its fuel is burnt in its engines.
