Here’s a detailed explanation and completion of the sentences using the correct forms of the verbs in the past simple, past continuous, and past perfect tenses. I'll explain each choice as well to make the reasoning clear:

A. Rachel was embarrassed because she (had brought) her dad’s boxer shorts to school.

• Explanation: The use of the past perfect ("had brought") here is appropriate because Rachel’s action of bringing the boxer shorts happened before she felt embarrassed. The past perfect tense is used to show that one action was completed before another in the past.

B. When I reached school this morning, the classes (had begun). Our English teacher was in the classroom and (was explaining) something. The students (were sitting) at their desks and (were listening) to her.

• Explanation:
  1. "Had begun": The classes had already started before the speaker reached school, so the past perfect tense is used to indicate this earlier action.
  2. "Was explaining": The teacher's action of explaining was ongoing at the time the speaker arrived, so the past continuous tense is used to depict an action in progress.
  3. "Were sitting" and "were listening": Similarly, these are ongoing actions happening at the same time as the teacher’s explanation, so the past continuous tense is used for both.

C. When I (came) yesterday, I (found) that I (had forgotten) to switch off the light in my room.

• Explanation:
  1. "Came": This is a simple past action describing the moment the speaker returned home.
  2. "Found": Another simple past action that happened after the speaker came home.
  3. "Had forgotten": The forgetting of the light happened before the speaker came home and realized it, so the past perfect tense is used to emphasize the earlier action.

D. When I (was going) to music school yesterday, I (met) Lucille in the street. We (had not seen) each other for ages, so we had a lot to talk about. We (chatted) so long that I was late for my piano lesson.

• Explanation:
  1. "Was going": The action of going to music school was ongoing when the speaker met Lucille, so the past continuous tense is used.
  2. "Met": A simple past action that occurred at a specific moment during the ongoing action of going to school.
  3. "Had not seen": The lack of seeing each other extended over a period of time before meeting Lucille, so the past perfect tense is used to describe this earlier state.
  4. "Chatted": A simple past action describing the conversation they had.
  5. "Was": A simple past action indicating the result of chatting too long (being late).
