Using the outline, answer the following question.

In an essay about the Apollo 13 mission, where should this sentence appear?

The mission should have proceeded normally, but problems arose during the flight.

a in the body of the essay as a topic sentence

b in the body of the essay as a supporting detail

c in the introduction

d in the conclusion

b in the body of the essay as a supporting detail

b in the body of the essay as a supporting detail

To determine where the sentence "The mission should have proceeded normally, but problems arose during the flight" should appear in the essay about the Apollo 13 mission, let's analyze the options:

a) In the body of the essay as a topic sentence: This option suggests that the sentence should serve as a main point for a paragraph in the body of the essay. However, since it states that the mission should have proceeded normally but encountered problems, it would be more suitable as a supporting detail rather than a topic sentence.

b) In the body of the essay as a supporting detail: This option aligns with the idea that the sentence should be a supporting detail in the body of the essay. It can be used to introduce and provide context for the events that occurred during the flight of Apollo 13.

c) In the introduction: Placing the sentence in the introduction would not be the most appropriate choice since it is more focused on outlining the historical importance of the mission, rather than introducing specific problems that occurred during the flight.

d) In the conclusion: Similar to the reason above, including the sentence in the conclusion would not be the best option as it is more concerned with summarizing the key points and lessons learned from the mission.

Based on this analysis, the most suitable option would be **b) in the body of the essay as a supporting detail**.
