Question 29

The green paint is a horrible color. I don't want it on my walls.

This sentence is punctuated correctly as it uses a period to separate two independent clauses, maintaining proper grammatical structure.

A) The green paint is a horrible color; I don't want it on my walls.

This option incorrectly uses a semicolon to join two independent clauses. While semicolons can link closely related ideas, the two sentences express distinct thoughts that do not require such a connection, making this punctuation incorrect.

B) The green paint is a horrible color. I don't want it on my walls.

This option is punctuated correctly. It clearly separates two independent clauses with a period, ensuring clarity and proper grammatical structure in the sentence.

C) The green paint is a horrible color. I don't want it on my walls.

This option is identical to option B and is also punctuated correctly. It uses a period to separate the two independent clauses appropriately, thus maintaining proper grammatical integrity.

D) The green paint is a horrible color? I don't want it on my walls.

This option incorrectly uses a question mark instead of a period, suggesting that the first clause is a question. Since the statement is declarative, the question mark is inappropriate and disrupts the sentence's meaning.

Conclusion

Option B is the only choice that accurately employs punctuation to separate two independent clauses, thereby ensuring clarity and grammatical correctness. Other options either misuse semicolons or question marks, leading to confusion or incorrect sentence structure. Thus, B stands out as the definitive correct answer.
