5. ____ you like playing computer games?

- a. Can
- b. Do ✔
- c. Are

7. My mother ____ a doctor. She works in a hospital.

- a. was
- b. is ✔

✔ Answer: b. is

8. There ____ a cake in a fridge. Where is it now?

- a. is
- b. was ✔
- c. were
- Explanation: "Where is it now?" implies the cake was there in the past, but isn’t anymore. So, past tense: was. "A cake" is singular → was.

✔ Answer: b. was

9. We usually ____ at home in the evening.

- a. stay ✔
- b. stays
