2. _______ you hungry yesterday evening?
3. _______ it cold yesterday?

Ответ:

1. was 2. were 3. was 4. was 5. was

Объяснение:

1) was your mum tired yesterday? (your mum - тоже самое, что и she, поэтому используем вспомогательный глагол was)

2) were you hungry yesterday morning? (для you/we/they используется were)

3) was it cold yesterday? (когда речь идёт о погоде всегда используется местоимение it, то бишь в этом случаем будет was)

4) was your teacher sad yesterday? (teacher = he/she)

5) was your pet hungry yesterday? (для животных в английском языке всегда используют местоимение it)
