Show Hint
Pay attention to subject-verb agreement when identifying errors in sentences. Singular subjects require singular verbs.
The error lies in the phrase "Sneezing occur". The subject "Sneezing" is singular, so the correct verb form should be "occurs" instead of "occur." The corrected sentence would be: "Sneezing occurs when irritants aren't caught by nasal hair."
