Make the sentences interrogative. 1.Mary cleaned her room yesterday.
2.You came home early last Tuesday.
3.He played football in the school yard.
4.We had lunch at 1 o'clock yesterday.
5.The family gathered in the living-room in the evening.
6.My friends wanted to play volleyball.
7.Tom's uncle lived in London last year. ​

1. Did Mary clean her room yesterday?
To make the sentence interrogative, we need to change the sentence structure by starting it with the helping verb "did" and then adding the subject "Mary" before the main verb "cleaned."

2. Did you come home early last Tuesday?
We need to do the same structure change here, starting with the helping verb "did" and then placing the subject "you" before the main verb "came."

3. Did he play football in the school yard?
Again, we apply the same structure change by starting the sentence with the helping verb "did" and placing the subject "he" before the main verb "played."

4. Did we have lunch at 1 o'clock yesterday?
We follow the same pattern, starting with the helping verb "did" and placing the subject "we" before the main verb "had."

5. Did the family gather in the living-room in the evening?
The structure change is applied by starting with the helping verb "did" and placing the subject "the family" before the main verb "gathered."

6. Did my friends want to play volleyball?
Using the structure change with the helping verb "did" and placing the subject "my friends" before the main verb "wanted."

7. Did Tom's uncle live in London last year?
Once again, we start with the helping verb "did" and place the subject "Tom's uncle" before the main verb "live."
