Question 15

To maintain muscle strength with aging, a regular and steady approach (consistently) is needed. "Occasionally" is too infrequent, and "proactively" focuses on taking initiative rather than the regularity required for muscle building. So the correct option is C.

Anatomically, the human heart is approximately the size of a clenched fist. A baseball is too large, and a small apple is not the typical comparison for heart size. So the correct option is A.

Answer:

C. consistently
