Ответ:

3. broke, were playing

4. dropped

5. saw, was waiting

Объяснение:

остальное верно

Past Continuous вместе с Past Simple задает фон (описывает длительное действие), а прерывает его короткое действие в Past Simple

например: It was raining. I was cooking dinner, when suddently somebody knocked on the door.

Ответ:

Broke, were playing

Dropped

saw, was waiting
