This question is incomplete because the text with the sentences is missing; here is the missing text:
1. In 6th grade, I sang in the school choir, and we often traveled to different places for our performances. 2. I didn’t mind traveling short distances, but I was nervous about going out-of-town. 3. Going out-of-town meant being away from home for a few days. 4. I had never been away from home before. 5. Before the first out-of-town trip, she sat me down and shared her own story about leaving home for the first time.
The answer to this question is A. Luckily, Mrs. Greene, the choir director, understood my nervousness.
Explanation:
In this paragraph, the narrator describes personal experiences related to going out of town as part of the school choir. In this text, sentence 4 explain show this was a new experience for the narrator, while in sentence 5 the narrator describes someone shared the experience of going out of town with the narrator; however, the narrator does not explain who is this person. In this context, the best is to add a sentence to introduce the new character in the story by explaining her identity. This is better achieved in "Luckily, Mrs. Greene, the choir director, understood my nervousness."
