1. We had just started lunch when the telephone rang.
   Телефон зазвонил после того, как мы начали обедать. Действие с when обозначает последующее событие, поэтому используется Past Simple — rang.

2. When I opened the safe, the money had disappeared.
   Деньги исчезли до того, как я открыл сейф. Более раннее действие выражается Past Perfect — had disappeared.

3. Andrew was late for school yesterday. When he got to the classroom, the lesson had started.
   Урок начался до того, как Эндрю вошёл в класс. Поэтому используется Past Perfect — had started.

4. They waited until everyone was ready and then they started the meeting.
   Сначала они подождали, а затем начали собрание. Это последовательные действия в прошлом, поэтому используется Past Simple — started.

Правильные ответы:

1. rang

2. had disappeared

3. had started

4. started
