Explanation:

In the text provided above, we can see that Andy wanted his letter to be chosen to be read during the break. This was something she wanted very much, but she knew that to achieve this goal she had to write something very good, with no flaws and that would please the students. For that reason, she ran through her goals, read her letter to the students and asked them how she could improve that letter. Each student then gave his suggestion and Andy got a letter that represented everyone, making sure that his letter was chosen.
