The answer would be 2. By.
1 Mark never used to be that lazy.
2 When they announced that our flight was cancelled, we had been waiting for two hours.
3 I was about to wash the car but then John care over then I never got round to it.
4 I slept until we had arrived at our destination
5 The last bus had left by the time we got to the bus terminal
6 Jason would bite his nails when he was a boy
7 We heard a funny noise coming from the cockpit while flying to Colombo
8 It was the first time I had sushi and i liked it
Personally, I would phrase it like this:
The choir moved the audience to tears with their beautiful voices.
