It seems like you're looking for assistance with the correct usage of "do/does" and "don't/doesn't" in sentences. I'll provide a detailed response to your question.

The choice between "do/does" and "don't/doesn't" depends on the subject of the sentence and whether it is singular or plural. Let's go through each sentence one by one:

1. Does your mother ski? - In this sentence, "your mother" is a singular subject, so we use "does" to form a question.

2. Yes, she does. - Here, we use "does" to affirm that your mother does ski.

3. Do Tom and Bob ski? - "Tom and Bob" is a plural subject, so we use "do" to form a question.

4. Yes, they do. - We use "do" to affirm that Tom and Bob do ski.

5. Do you help your mother? - Since "you" is the subject, we use "do" to form the question.

6. Yes, I do. - "I" is the subject, so we use "do" to affirm that you help your mother.

7. Does Tom help his mother? - Since "Tom" is a singular subject, we use "does" to form the question.

8. No, he doesn't. - Here, we use "doesn't" to indicate that Tom doesn't help his mother.

9. Does his aunt swim? - "His aunt" is a singular subject, so we use "does" to form the question.

10. No, she doesn't. - We use "doesn't" to indicate that his aunt doesn't swim.

11. Do his aunts skate? - "His aunts" is a plural subject, so we use "do" to form the question.

12. No, they don't. - We use "don't" to indicate that his aunts don't skate.

13. Do Tom and you see the bird? - "Tom and you" is a plural subject, so we use "do" to form the question.

14. No, we don't. - Here, we use "don't" to indicate that Tom and you don't see the bird.

15. Do they swim? - "They" is a plural subject, so we use "do" to form the question.

16. Yes, they do. - We use "do" to affirm that they do swim.

17. Do you ski? - Since "you" is the subject, we use "do" to form the question.

18. No, we don't. - Here, we use "don't" to indicate that you don't ski.

19. Does this bird sing? - "This bird" is a singular subject, so we use "does" to form the question.

20. Yes, it does. - We use "does" to affirm that this bird does sing.

21. Does that dog jump? - "That dog" is a singular subject, so we use "does" to form the question.

22. No, it doesn't. - Here, we use "doesn't" to indicate that that dog doesn't jump.
