Write three sentences, each using a comma in a different way. Explain why the comma is needed in each sentence.

Make them short

1. I went to the store, bought some groceries, and then headed home.

In this sentence, the comma is used to separate three independent clauses that are joined by the conjunction "and". It helps to indicate a pause and separate the ideas within the sentence.

2. In my garden, I have roses, tulips, and daisies.
Here, the comma is used to separate items in a series or list. It helps to clearly distinguish each item and avoid confusion or ambiguity.

3. The book I borrowed from the library, which was recommended by my friend, is a thrilling mystery.
In this sentence, the comma is used to set off a nonessential or non-restrictive clause. The phrase "which was recommended by my friend" provides additional information about the book but is not necessary for understanding the main subject and predicate of the sentence.
