Thank You for responding.

You are always a great help to me. :)

You're welcome. Glad I could help -- and glad you understand these tricky pronouns. :-)

Sure! Let's go through each question and check if they are correct or not.

1. Who is that man?
This question is grammatically correct. It is a generic question asking for the identity of a man.

2. Who made the first moon landing?
This question is also correct. It is asking for the identity of the person or group who made the first moon landing.

3. Whom did the instructor invite to speak to the class?
This question is incorrect. The correct form of this question would be, "Who did the instructor invite to speak to the class?" In informal English, the use of "whom" is becoming less common, so using "who" in this case would be more natural.

4. Whom did you see at the park?
This question is incorrect. The correct form of this question would be, "Who did you see at the park?" Again, the use of "who" is more common in informal English.

5. Whom will you write about?
This question is incorrect. The correct form of this question would be, "Who will you write about?" Using "who" instead of "whom" is more appropriate in this case.

6. Whom did you drive to the store?
This question is incorrect. The correct form of this question would be, "Who did you drive to the store?" Using "who" instead of "whom" is more appropriate here.

7. Who owns that new blue car?
This question is grammatically correct. It is asking for the owner of a new blue car.

8. Whom did you help last week?
This question is incorrect. The correct form of this question would be, "Who did you help last week?" Using "who" instead of "whom" is more appropriate here.

9. Who wrote that clever poem?
This question is grammatically correct. It is asking for the author of a clever poem.

10. Whom will you ask to help you move?
This question is incorrect. The correct form of this question would be, "Who will you ask to help you move?" Using "who" instead of "whom" is more appropriate here.

In summary, most of your questions are grammatically correct, although some of them use "whom" incorrectly. In informal English, it is more common to use "who" in most cases instead of "whom". It's always a good idea to check the grammar rules and usage guidelines for specific question forms to ensure accuracy.
