Question

read the text.
many people divide exercise into one of two categories: strength training or aerobic. strength training refers to activity that uses weights or a persons body weight to strengthen muscle, while aerobic exercise refers to activity that increases the heart rate for an extended period of time. athletic trainers often advise people to wait at least forty-eight hours between strength training workouts, to give their muscles time to heal. aerobic workouts, on the other hand, can be done more frequently.
which organizational structure does this text primarily use?
sequential
compare-contrast
problem-solution

Explanation:

The text first introduces two exercise categories, then defines each, and explicitly contrasts their recommended workout frequency using the phrase "on the other hand". This structure focuses on highlighting similarities and differences between the two types of exercise.

Answer:

compare-contrast
