Вот как я бы выбрал правильные формы глаголов для каждого предложения, учитывая контекст времени и тип действия:

1. When I _____ home yesterday, my mom _____ dinner.
   Правильный вариант: b) came / was cooking
   Объяснение: Действие "came home" произошло в конкретный момент в прошлом (past simple), а "was cooking" — длительное действие, происходившее в тот момент (past continuous).

2. Sarah _____ to Paris three times.
   Правильный вариант: b) has been
   Объяснение: Здесь используется present perfect, так как речь идет о жизненном опыте до настоящего момента, а не о конкретном прошлом событии.

3. While Tom _____ his homework, his sister _____ TV.
   Правильный вариант: b) was doing / was watching
   Объяснение: Оба действия длились одновременно в прошлом, поэтому используем past continuous для обоих.

4. I _____ my keys. Have you seen them?
   Правильный вариант: c) have lost
   Объяснение: Present perfect показывает, что действие имеет результат в настоящем — ключи потеряны сейчас.

5. When the phone _____, I _____ in the shower.
   Правильный вариант: a) rang / was
   Объяснение: "Rang" — короткое завершённое действие в прошлом (past simple), "was in the shower" — длительное действие в прошлом (past continuous).

6. They _____ each other since high school.
   Правильный вариант: b) have known
   Объяснение: Present perfect используется для действий, которые начались в прошлом и продолжаются до настоящего момента.

7. While we _____ in the park, it started to rain.
   Правильный вариант: b) were walking
   Объяснение: Действие "were walking" длилось в момент, когда произошло событие "started to rain" — past continuous + past simple.

8. Jack _____ his arm when he _____ off his bike.
   Правильный вариант: a) broke / fell
   Объяснение: Оба действия произошли в прошлом, одно за другим, поэтому past simple для обоих.

9. How long _____ you _____ English?
   Правильный вариант: c) have / studied
   Объяснение: Present perfect используется для вопросов о длительном опыте до настоящего момента.

10. The children _____ in the garden all afternoon yesterday.
    Правильный вариант: b) were playing
    Объяснение: Действие происходило в течение определённого времени в прошлом, поэтому past continuous.

✅ Итого правильные ответы:
1-b, 2-b, 3-b, 4-c, 5-a, 6-b, 7-b, 8-a, 9-c, 10-b
