Final answer:
To correct the sentence, insert a comma before the coordinating conjunction 'or': 'I could donate these old clothes to charity, or I could host a clothing swap with my friends.' This separates the two independent clauses, providing clarity.
Step-by-step explanation:
To correct the sentence by inserting one comma, you should place it before the coordinating conjunction 'or' to separate the two independent clauses. The corrected sentence will read: 'I could donate these old clothes to charity, or I could host a clothing swap with my friends.' In this case, the comma serves to clarify the separation of ideas and helps to prevent a run-on sentence.
Reviewing the example sentences provided for the usage of commas:
- '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.'
Remember to use commas with coordinating conjunctions, subordinating conjunctions, and introductory phrases, and avoid using commas around essential information.
