Subject-Verb Agreement Error Correction

This subject-verb agreement error correction exercise trains you to proofread complete English sentences, not just choose a verb from a gap. Agreement errors happen when the verb matches the wrong noun, misses the third-person -s, or uses the wrong form after there is, there are, either...or, or neither...nor. In each question, read the whole sentence, find the true subject, then decide whether one chunk needs editing.

Wrong: "The folder of receipts are missing." Correct: "The folder of receipts is missing."
Wrong: "There is several reasons to wait." Correct: "There are several reasons to wait."

The key proofreading habit is to ignore distracting nouns. In a phrase like of the receipts, the plural noun is not the subject. With questions and negatives, remember that do, does, don't, and doesn't carry the agreement marker, so the main verb stays in its base form.
