Explanation:
We need to choose between don’t and doesn’t for each sentence. Here's how to decide:

- Use don’t with:
- I, you, we, they
- plural nouns (e.g., cows, Ann and I, my sister and I)

- Use doesn’t with:
- he, she, it
- singular nouns (e.g., my sister, the dog, my mum, my cat, this man, her friend)

Now let’s go sentence by sentence:

1. I ___ like chicken.
→ Subject = *I* → use don’t

2. My sister ___ eat pasta.
→ *My sister* = third person singular (she) → doesn’t

3. You ___ buy apples.
→ *You* → don’t

4. The dog ___ bark.
→ *The dog* = third person singular (it) → doesn’t

5. My mum ___ read comics.
→ *My mum* = she → doesn’t

6. Ann and I ___ go to school.
→ *Ann and I* = we (plural) → don’t

7. Cows ___ live in the sea.
→ *Cows* = plural → don’t

8. They ___ play football.
→ *They* → don’t

9. My cat ___ chase mice.
→ *My cat* = it → doesn’t

10. Her friend ___ speak English.
→ *Her friend* = he/she → doesn’t

11. This man ___ smoke.
→ *This man* = he → doesn’t

12. It ___ run very fast.
→ *It* → doesn’t

Let me double-check each:
1. I don’t ✔
2. My sister doesn’t ✔
3. You don’t ✔
4. The dog doesn’t ✔
5. My mum doesn’t ✔
6. Ann and I don’t ✔
7. Cows don’t ✔
8. They don’t ✔
9. My cat doesn’t ✔
10. Her friend doesn’t ✔
11. This man doesn’t ✔
12. It doesn’t ✔

All correct.

Final Answer:
don’t, doesn’t, don’t, doesn’t, doesn’t, don’t, don’t, don’t, doesn’t, doesn’t, doesn’t, doesn’t
