Question

decide whether each sentence is punctuated correctly. use the drop-down menus to indicate which revisions, if any, are necessary.
the american author, harper lee, published only one novel.
remove both commas
remove comma after author
no revision needed
i won first prize in the pet show.
jeromes brother, a sophomore at my school, is running for student council.

Explanation:

1. For "The American author, Harper Lee, published only one novel.": "Harper Lee" is essential to identify which American author is referenced (it is a restrictive appositive), so commas around it are incorrect and should both be removed.
2. For the incomplete sentence "I won first prize in the pet show.": No commas are needed here as the sentence is a simple, correctly punctuated independent clause with no non-restrictive elements requiring commas.
3. For "Jerome’s brother, a sophomore at my school, is running for student council.": "a sophomore at my school" is non-restrictive extra information about Jerome's brother, so the commas around it are correct, and no revision is needed.

Answer:

1. The American author, Harper Lee, published only one novel.: remove both commas
2. I won first prize in the pet show.: no revision needed
3. Jerome’s brother, a sophomore at my school, is running for student council.: no revision needed
