Example Question #15 : Correcting Punctuation Errors: Commas For Dependent Clauses

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

When you talk to your mother like, that you bring shame on the whole family.

Possible Answers:

When you talk to your mother like that you bring shame on the whole, family.

When you talk to your mother like, that you bring shame on the whole family.

When you talk to your mother like that you bring shame on, the whole family.

When, you talk to your mother like that, you bring shame on the whole family.

When you talk to your mother like that, you bring shame on the whole family.

Correct answer:

When you talk to your mother like that, you bring shame on the whole family.

Explanation:

A dependent clause, or a clause which cannot stand on its own, must be separated from the main clause in a sentence by a comma. The full dependent clause in the example sentence is the introductory phrase "When you talk to your mother like that," not "when you talk to your mother like." Thus, the comma attempting to separate the introductory clause in the sentence above actually creates a comma splice error. The best way to correct the underlined portion above is, "When you talk to your mother like that, you bring shame on the whole family."

Example Question #3995 : Sat Writing

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

He's always bothering his classmates, it's just what he does.

Correct answer:

He's always bothering his classmates, it's just what he does.

Explanation:

A dependent clause, or a clause which cannot stand on its own, must be separated from the independent clause in a sentence by a comma. In the example sentence "it's just what he does" is a dependent clause that explains the main clause, and thus must be separated from the main clause with a comma.
