Final answer:
The best topic sentence for the paragraph is 'C. There are only a few kinds of housework that I enjoy' because it accurately reflects the specific housework tasks the writer enjoys. Additionally, the revised sentences incorporate proper comma usage.
Step-by-step explanation:
For the example paragraph provided, the best topic sentence is C. There are only a few kinds of housework that I enjoy. This sentence accurately sets up the paragraph which goes on to list the specific types of housework that the writer finds pleasurable. It reflects the content of the paragraph where the writer names only a few tasks (vacuuming, washing dishes, cleaning the garage) they like doing, indicating that they do not enjoy most of the other housework chores.
When reviewing the example sentences provided for comma usage, the revisions would be:
- I finally found my keys, and I got to work just in time.
- Mrs. Contreras threw out her old coffee table and cleaned the carpet.
- Taking the elevator to the roof, we hoped we could see the skyline and the bay.
- Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy.
- I let my neighbor borrow my phone because she said hers was tapped by the police.
As for the mixed-construction sentence, the corrected version is more concise and straightforward: People who have hobbies are happier than others. This eliminates the redundancy and awkward construction of the original sentence.
