A. As the evidence shows, moderate exercise can be beneficial to good health.

The sentence that could appear in a conclusion is option A: "As the evidence shows, moderate exercise can be beneficial to good health."

To determine this, let's analyze each option:

A. This sentence states a conclusion by summarizing the evidence that moderate exercise is beneficial to good health. It directly addresses the main idea of the conclusion.

B. This sentence is more of a question than a statement. It raises a query about whether moderate exercise is as beneficial as intense exercise, rather than providing a definitive conclusion.

C. This sentence presents a specific finding from a study but does not explicitly provide the overall conclusion or implications.

D. This sentence describes the composition of a program but does not offer a conclusion or final remark based on the study or evidence.

Therefore, option A is the sentence that best represents a conclusion as it sums up the evidence and provides a statement that follows from it.
