Answer:
Brennan was worried that his car might break down after he noticed a quiet clunking noise coming from his engine.
Step-by-step explanation:
The word "quite" is used incorrectly in the sentence. It should be "quiet" to indicate a low volume or lack of noise. "Quite" means "completely" or "to a significant extent." Therefore, replacing "quite" with "quiet" makes the sentence grammatically accurate and conveys the intended meaning of a low, subdued noise coming from the engine.
