Write three sentences, each using a comma in a different way. Explain why the comma is needed in each sentence.(4 points) but one sentance for each

1. I need to buy apples, oranges, and bananas at the grocery store.

In this sentence, the comma is used to separate the items in a list (apples, oranges, and bananas). It helps clarify the different elements being mentioned.

2. After finishing my homework, I decided to go for a run.
The comma is used here to indicate a pause in the sentence, separating the introductory clause "after finishing my homework" from the main clause "I decided to go for a run".

3. The dog, a playful Labrador, was chasing its tail in the backyard.
In this sentence, the comma is used to provide extra information about the noun that comes before it. The phrase "a playful Labrador" is a non-essential clause, as it could be omitted without changing the basic meaning of the sentence. The comma helps set it apart from the rest of the sentence.
