'Boat' is related to 'Oar' as the manual driving mechanism. In the same way, 'Bicycle' is related to which part that provides manual drive?
Correct Answer: Pedal
Introduction / Context:The analogy captures the component used to manually propel or drive the vehicle. An oar manually propels a boat. For a bicycle, the part that the rider pushes to drive the chain and wheel is the pedal.
Given Data / Assumptions:
- Oar → manual propulsion for boats.
- Bicycle → manual propulsion via pedal and crank system.
Concept / Approach:We match “vehicle : manual driving component.” The pedal on a bicycle is the direct analog to the oar on a boat—both convert human effort to motion.
Step-by-Step Solution:
1) Identify the manual propulsion part for the boat: oar. 2) Identify the manual propulsion part for the bicycle: pedal. 3) Select “Pedal” as the parallel driving mechanism.Verification / Alternative check:Wheels and seats are structural/ride components; handles steer; roads are external surfaces and not vehicle parts.
Why Other Options Are Wrong:
- Wheel: Enables rolling but is not the manually operated driver.
- Seat: For support, not propulsion.
- Handle: Steering component.
- Road: Not a component of the bicycle.
Common Pitfalls:Picking a critical part (wheel) that is necessary but not the manual driver in the same sense as the oar is for the boat.
Final Answer:Pedal
