Find the part of the sentence that contains an error:
He is a (1) / quick runner and (2) / a smart think (3) / as well(4).
Show answer & explanation
Correct answer: C
Explanation
Correct Answer
a smart think (3)
Explanation
The error is in part (3) because “think” is a verb, but here a noun is required to match “runner.” The correct word should be “thinker,” which is the noun form.
The correct sentence should be:
“He is a quick runner and a smart thinker as well.”
Key Points
Error: Incorrect word form (verb used instead of noun)
Rule: Parallel structure requires matching noun forms
Correct usage: smart thinker
