Final answer:
The sentence 'That restaurant is famous for its delicious homemade pies and cakes.' does not need commas as there is no series or non-essential information. Commas are essential for clarity when listing items or separating independent clauses, and they should not be used to split subjects from verbs or essential clauses.
Step-by-step explanation:
When inserting commas in sentences, it's crucial to identify whether the information is essential to the meaning of the sentence or not. In the given sentence about the restaurant, no commas are required because the adjectives 'delicious' and 'homemade' directly modify 'pies and cakes' and are not a list that requires separation. However, when dealing with a series of items, including conjunctions that join two independent clauses, or non-essential clauses, commas become necessary for clarity.
Here's how to correctly use commas in the provided review questions:
- 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.
Notice how commas are used to separate independent clauses, set off nonessential information, and in lists to avoid confusion.
