Two independent clauses that can each stand alone must be separated by either a period or a semicolon, or connected by a comma followed by a conjunction. Because this sentence doesn't include a conjunction like "and" after its comma, it is incorrect. (This error, where two independent clauses are incorrectly connected by a comma, is known as a "comma splice.")

Sarah wanted to arrive at the store in time to buy the fresh bread cereal, and chocolate sauce. No error

Possible Answers:

to arrive

No error

fresh bread

in time

Example Question #1 : Identifying Punctuation Errors: Commas

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Bill, Jane and Jared went to the movies every Sunday afternoon; they liked to sit at the back of the movie theatre because it offered the best view. No error

Possible Answers:

No error

Bill, Jane and Jared 

afternoon; they

every

it offered 

Correct answer:

Bill, Jane and Jared 

Explanation:

The phrase “Bill, Jane and Jared” should be “Bill, Jane, and Jarred” because the friend’s names are presented as a list. Words, clauses, or phrases in a series should always be separated by a comma. The sentence “Bill and Jane went to the movies” does not require a comma, but adding the third name, Jared, requires a comma between the three names. Be sure to note that there is no comma after the last word or phrase in the sequence.
