Question

the author wrote this text most likely to
a show why running is healthy.
b explain why canada is a big country.
c prove that runners need to practice.
d tell about a person who helped others.

Explanation:

To determine the author's purpose, we analyze each option. Option A is crossed out, so it's incorrect. Option B about Canada's size is unrelated to typical text purposes (unless the text is about geography, but the other options relate to running/people). Option C focuses on runners' practice, but Option D (telling about a helper) is a common narrative purpose. Since A is invalid, and B/C don't align with a likely text focus (vs. a story about a helpful person), D is the best choice.

Answer:

D. tell about a person who helped others.
