Question

5. We ____(to do) all the work by that time a) to do c) had done b) did d) had had​

Answer 1

Ответ:

Варіант ( с) we had done all the work

Answer 2

The correct answer is c) had done. This is the past perfect tense, which is used to refer to a past action that occurred before another past action. The past perfect is formed using had and the past participle of the main verb. For example:

- We had done all the work by that time. - She had gone to bed when he arrived. - They had been painting the house for two hours.

The past perfect tense is often used together with the simple past tense to show the sequence of the events in the past. For example:

- After we had finished dinner, we watched a movie. - He realized that he had left his wallet at home. - She was happy because she had passed the exam.
