Write three sentences, each using a comma in a different way. Explain why the comma is needed in each sentence. Make one sentence about the store and why

Answer 1

1. After a long day at work, I decided to stop by the store for some groceries.
   The comma is needed after "work" to separate the introductory clause from the main clause, making the sentence clearer and helping with the flow of reading.

2. The store, known for its fresh produce, recently started selling organic products.
   The commas around "known for its fresh produce" set off the non-essential clause that adds extra information about the store without changing the main point of the sentence.

3. I wanted to buy apples, bananas, and oranges.
   The comma is needed before "and" in this list of items (the Oxford comma) to clarify that each fruit is a separate item; it helps prevent ambiguity.
