Final answer:
The best revision to combine the given sentences stylistically is option A. It conveys clear connection and context within one sentence. Additionally, in the review questions, comma placement is essential for clarity, and the mixed-construction sentence is rephrased to correct the grammatical confusion.
Step-by-step explanation:
The question is asking which revised sentence best combines the given sentences to improve the style. Among the available options, revision A is the one that effectively combines the sentences into a single, cohesive sentence without changing the original meaning. This revision connects the event of the computer crashing with the specific context in which it happened, namely while the student was working on a history term paper due on Friday. The construction of this sentence is clear and precisely conveys the time-sensitive nature of the situation.
Now let's address the review questions provided. When inserting missing commas or omitting incorrectly placed commas, it is crucial to follow grammatical rules to clarify the meaning of the sentences and to separate items correctly.
- 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.
Regarding the mixed-construction sentences, the second example is corrected by rewriting it as: "Starting my general studies classes last semester gave me the opportunity to take classes in my major this fall." This rephrased sentence eliminates the confusion and makes the subject and the verb clear.
