2 answers

1. Her mother gave her hot soup.
"a" is unnecessary because we are talking about SOME hot soup, not a specific container. You could, however, say "a bowl of hot soup"

3. A mouse is generally smaller than a rat.

4. Technically, you should pronounce every "th"

5. We don't usually use "those" for people. The better Question would be "who are these people?" and then your answer would be correct. A better answer to the question you posted would be "those are apples."

6. Seems fine.

7. We use math here

8. Both are acceptable, but it would be more natural to say "what food do you eat for breakfast/dinner/etc."

9. She has a cough

10. "She has a low fever" is acceptable. "a" is necessary.

11. #11 is correct.
11. Both # 11 and 11a would be correct.
