3. She had never travelled by plane before she went to Egypt last year. (Past perfect for an experience before a past event, and past simple for the past event)


4. I had already finished my homework when my friends arrived. (Past perfect for an action completed before another past action)


5. He had been interested in history before the re-enactment society visited his school. (Past perfect for a state prior to a past event)
