Answer:
A. The proposition-and-support structure provides details about school-spirit week in order to illustrate why it is important.
Explanation:
In the question, they asked what organizational structure of the passage helps to develop the main idea. After reading the entire passage, we can tell the main idea is in the first sentence that spirit-week is very important. The rest of the lines are just reasons to support that spirit-week is important. (rally together in line 2, work together in line 3, unwinding in line 4, best memories made in line 5)
For option B, there was no mentioning of what happened first during spirit-week so this is wrong.
For option C, there was no mentioning of what might happen if there were no spirit-week.
For option D, this passage is not a compare-and-contrast structure. Furthermore, there was no mentioning of proposing new student activities.
