Explanation
The correct answer to the analogy "MARATHON is to RACE as HIBERNATION is to _____?" is D: Sleep.
In this analogy, the relationship between "marathon" and "race" is that a marathon is a type of race. Similarly, the relationship between "hibernation" and the answer choice must be that hibernation is a type of that answer choice.
While winter, bear, and dream may be associated with hibernation in some way, "sleep" is the best answer choice that reflects a type of activity or state that is commonly associated with hibernation. During hibernation, animals typically sleep for extended periods of time, and their body temperature drops to conserve energy.
Therefore, the correct answer is D: Sleep.
