Question

Which sentence does not contain any errors in comma usage?

A.The artist paints landscapes and animals and then she sells her artwork at the outdoor market.
B.Many farmers planted corn, and others planted soy beans.
C.Jeremy sent a letter in the mail, but, later that week Katie replied by e-mail.
D.A factory recently closed in Pittsburgh but, another one is opening soon.

Answer 1

B is the answer because you pit a comma before and when it is used.

Answer 2

The answer is B. A comma rule I learned in school is: Use a comma before and, but, or, nor, for, yet, when there is a complete sentence on either side.

Hope that helped
