Fill in the blanks with the most appropriate words. Max didn’t _____yesterday afternoon; he____at home.

The correct answer is C. Went out / stayed.

The verb “go out” is used to describe the action of leaving one’s home to go somewhere else. The verb “stay” is used to describe the action of remaining in one place. In this sentence, Max is described as not going out, so the first blank should be filled with the past tense form of “go out,” which is “went out.” The second blank should be filled with the past tense form of “stay,” which is “stayed.”

Option A is incorrect because the past tense form of “go out” is “went out,” not “go out.” Option B is incorrect because the past tense form of “stay” is “stayed,” not “stay.” Option D is incorrect because the past tense form of “go out” is “went out,” not “went.”
