Answer 1

This exercise is the easiest of all

Answer 2

This exercise is the easiest of all. "Easy" is the comparative form of the adjective "easy." When we use the comparative form, it means that we are comparing two things and stating that one is easier than the other. In this case, we are comparing this exercise to other exercises. Out of all the exercises, this one is the easiest. It implies that there are other exercises that are more challenging or difficult. Using the comparative form allows us to specify the degree of ease in relation to other exercises. It provides clarity and helps us understand the relative difficulty level of different tasks.
