The correct answer is measure.

Explanation:

The purpose of this assignment is to find connections between the first two words and then draw an analogy to figure out the missing word. First, you need to pay attention to the word “develop.”

Developing means planning, elaborating, trying out different ideas, and bringing them to a realization. Soon comes the time when you need to check whether you accomplished the goals that you set for yourself, so you need to “assess.”

Thus, the logic in the first word pair is a process and its evaluation. The same should be applied to the second word pair. If you are training someone or even yourself, you are doing it to have a certain result. Every result is more or less measurable. Thus, the word that you are looking for is measure.
