Example Question #1 :Identifying Punctuation Errors: Commas For Introductory Or Interrupting Phrases

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

to the beach make sure

If you decide

No error

to wear

Correct answer:

to the beach make sure

Explanation:

The phrase "If you decide to go to the beach" is an introductory phrase, and all introductory phrases need to be set apart from the rest of the sentence by a comma. So, after being corrected, the sentence would read, "If you decide to go to the beach, make sure to wear sunscreen to protect your skin!"

No error

relationship; even

among

sisters, Margot, and

her sister, Margot,

Correct answer:

sisters, Margot, and

Explanation:

Because the sentence states that Margot is not Daisy's only sister, the commas and which frame her name in "their numerous older and younger sisters, Margot, and Daisy" are incorrect. The comma that sets apart Margot's name at the beginning of the sentence ("Daisy and her sister, Margot, shared") is correctly used, because here, Margot is being specified as Daisy's sister in an appositive phrase that renames "her sister" as "Margot."

Perdita the lost princess,wasfound and raisedby a shepherd.No error

Possible Answers:

Perdita the lost princess,

No error

was

by a shepherd.

found and raised

Correct answer:

Perdita the lost princess,

Explanation:

Commas should be used to set off the phrase "the lost princess," as it is in apposition to (gives a description of) the subject Perdita, but the sentence still makes sense without it. So, "Perdita the lost princess," contains the sentence's error, and the sentence should read, "Perdita, the lost princess, was found and raised by a shepherd."
