Final answer:
Sentence A: 'We forgot to pack utensils I will run to the store' is a run-on sentence because it contains two independent clauses without proper punctuation or a conjunction. To fix it, a period, semicolon, or coordinating conjunction can be added.
Step-by-step explanation:
The run-on sentence you've asked about is Sentence A: We forgot to pack utensils I will run to the store. This is a run-on sentence because it consists of two independent clauses incorrectly joined without proper punctuation or conjunctions. To correct it, you can add a period, a semicolon, or a comma with a coordinating conjunction. For example: We forgot to pack utensils; I will run to the store. or We forgot to pack utensils, so I will run to the store.
As for the review questions about comma usage:
- Before and after 'and' if it is connecting two independent clauses. Final sentence: I finally found my keys, and I got to work just in time.
- The comma before 'and' is unnecessary as it is not connecting two independent clauses. Final sentence: Mrs. Contreras threw out her old coffee table and cleaned the carpet.
- A comma after 'elevator' would clarify that the succeeding phrase modifies the taking of the elevator. Final sentence: Taking the elevator to the roof, we hoped we could see the skyline and the bay.
- A comma is needed after 'well' to set off the introductory phrase. Final sentence: Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy.
- The existing comma is correctly placed, making the purpose of borrowing the phone clear. The sentence is correct as written.
