Question 20

There are physical and psychological reasons for a daily walk.

This sentence effectively encapsulates the main idea of the paragraph by indicating that both physical and psychological benefits will be discussed in relation to walking daily.

A) One of the easiest ways to lose weight is to take a walk on a daily basis.

While this option mentions walking as a means to lose weight, it narrows the focus to weight loss, which may not encompass the broader benefits of walking that the paragraph aims to address, thereby limiting the scope of discussion.

B) Exercise does not have to be difficult; consider walking.

This statement suggests that walking is an easy form of exercise, but it does not explicitly mention the reasons for walking or the benefits associated with it. As a topic sentence, it lacks the depth needed to introduce a discussion on the various advantages of walking.

C) If you want to get in shape, the first step is to get moving.

This option implies that movement is essential for getting in shape but does not specifically highlight walking or the specific benefits associated with it. It is too vague to serve as an effective topic sentence for a paragraph focused on the reasons for daily walking.

D) There are physical and psychological reasons for a daily walk.

This sentence directly addresses both the physical and psychological aspects of walking, making it the most comprehensive choice. It sets the stage for an informative exploration of the various reasons for incorporating walking into daily routines.

Conclusion

The correct answer, "There are physical and psychological reasons for a daily walk," is the most suitable topic sentence as it provides a clear and broad perspective on the benefits of walking. In contrast, the other options either focus too narrowly on weight loss, lack specificity, or do not clearly establish the dual aspects of physical and psychological benefits, thus failing to adequately introduce the core theme of the paragraph.
