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.

1. Both sentences are grammatically correct. The difference in usage lies in the specific meaning being conveyed.

- "Her mother gave her a hot soup" suggests that the mother gave the person a serving of hot soup, without specifying the type of soup.
- "Her mother gave her hot soup" implies that the mother gave the person hot soup, emphasizing the quality or temperature of the soup.

2. The main difference between a mouse and a rat is their size. Generally, a rat is larger than a mouse. However, there are different species of both mice and rats, so size variations can exist within each category.

3. In English, the pronunciation of "sixth" and "month" varies depending on the speaker and accent. Generally, the "th" sound is pronounced as a fricative sound, similar to the "th" in "thin." However, when these words are pronounced together in rapid speech, the "th" sound may be reduced, and it may sound more like a linking sound, blending into the following word.

4. The answer "They are my friends" is correct and grammatical. The word "they" refers to multiple friends, indicating that the speaker is claiming ownership of those friends.

5. The sentence "They are my friends" is grammatically correct. The use of "they" implies that the friends belong to the speaker, indicating possession.

6. Both "math" (short for mathematics) and "maths" (short for mathematics) are used as subjects in school, depending on the regional variation. In American English, "math" is commonly used, while in British English, "maths" is preferred. Both are considered correct in their respective contexts.

7. Both "What food do you have for meals?" and "What fruit do you have for meals?" are grammatically correct. The choice between "food" and "fruit" depends on what specific aspect of meals the question is asking about. "Food" is a more general term, while "fruit" refers specifically to that food group.

8. Among the three options, "She has a cough" is the correct one. The use of the article "a" before "cough" indicates that she has one instance of a cough. "She has coughs" and "She has cough" are grammatically incorrect in this context.

9. Both "She has a high fever" and "She has a slight fever" are correct sentences. Regarding the phrase "She has a low fever," it is possible to say, but it may not be as commonly used as "high" and "slight." The use of the article "a" is optional, and it depends on the specific context or emphasis intended.

10. Both options, #11 and #11-1, are grammatically correct. The choice between the two depends on whether Tony is addressing Sally and Tim together or specifically mentioning each individual. If Tony wants to address them as a group, #11 would be appropriate. If Tony wants to address Sally and Tim individually, #11-1 would be suitable.
