Marathon is to race as hibernation is to what?

• A. winter
• B. bear
• C. dream
• D. sleep

Answer: (D)

A marathon is a specific type of race, emphasizing the idea of a long-duration event. Similarly, hibernation is a specific form of sleep that occurs in some animals during certain seasons, primarily to conserve energy and survive when food is scarce.

The relationship established between the two pairs is that both marathon and hibernation represent a particular category of a more general concept—in this case, race and sleep, respectively. While options like "winter," "bear," and "dream" might relate to hibernation, they do not encapsulate the underlying concept of hibernation in the same manner that "sleep" does. Sleep is the broader category under which hibernation falls, much like race is the broader category under which marathon falls. Thus, the best fit for the analogy is the relationship of hibernation to sleep.
