Final answer:
The student's English language question pertains to the proper use of commas in sentence structure. Corrections were provided for each sentence, emphasizing the importance of understanding comma usage rules for clear communication.
Step-by-step explanation:
The passage and review questions you have provided are related to comma usage and sentence structure in the English language. The exercise asks for the correction of the placement of commas in various sentences. When punctuating sentences, it is important to know the rules for using commas correctly. For example, commas are often used to separate independent clauses connected by a conjunction, segregate introductory elements, or divide items in a list.
Here are corrections for the comma placement in the provided sentences:
- 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. (No comma needed here because it's not an independent clause following 'and'.)
- Taking the elevator to the roof, we hoped we could see the skyline and the bay. (Here, 'and' connects two objects in a list, so no comma is needed.)
- 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. (No comma is needed here as it's not a separate clause but a reason for the main clause.)
Understanding these rules can prevent confusion and convey the intended meaning clearly to readers.
