Which pair represents a similar relationship as pedal : bicycle?

• A. inch : yardstick
• B. walk : skip
• C. tire : automobile
• D. oar : canoe

Answer: (D)

The relationship represented by the pair pedal : bicycle involves a component that is essential for the function or operation of the vehicle. A pedal is a crucial part of a bicycle, as it is what allows the rider to propel the bicycle forward.

In the case of oar : canoe, the relationship is similar because an oar is an essential component used to propel and maneuver a canoe through the water. Just as pedals are necessary for operating a bicycle, oars are necessary for operating a canoe.

The other options do not express the same kind of component-to-whole relationship. While an inch is a unit of measurement related to a yardstick, they do not have the same functional dependency. Walking and skipping are two different forms of movement rather than components of a single operation. A tire is indeed associated with an automobile but represents a different aspect, as a tire is one of many components of the vehicle rather than being essential for its specific operation like a pedal for a bicycle.
