Answer:
The relationship is problem:solution.
Explanation:
An analogy draws a relationship between two different things. The purpose is to compare those things by finding something that connects them, despite the differences. An example of relationship found in analogies is the performer-action relationship (actor:act; worker:work).
When we analyze the words exhaustion:sleep and try to connect them, we realize that sleep serves to "cure" exhaustion, so to speak. Exhaustion is the feeling of extreme tiredness. It is a problem since it prevents people from working, studying etc. Sleep is what people do when they feel tired. Sleep is restorative, people feel energized after sleeping for a few hours. Thus, sleep is the solution for exhaustion.
