PSAT Writing and Language Question 473: Answer and Explanation

Question: 473

• A. NO CHANGE
• B. One thing is certain there
• C. One thing is certain: there
• D. One thing, is certain there

Correct Answer: C

Explanation:

(C) Both "one thing is certain" and "there isn't a millennial out there who cannot recognize the lightning bolt scar etched into Harry's forehead" could be complete sentences independently. Therefore, proper punctuation is required to separate these two clauses. A colon is the best option here, as seen in choice (C). The colon serves as a sort of lead-in from clause 1 to clause 2. Choice (A) causes a run-on sentence while choices (B) and (D) neglect punctuation entirely.
