Question

look at the text below. if there is an error with subject - verb agreement, select the incorrect verb and type it correctly. otherwise, submit the text without making any changes. \my chickens are more than thirty weeks old, but none are laying eggs yet,\ mr. quinn told his neighbor, avery.

Explanation:

The subject "none" here refers to "none of the chickens" (a plural subject in context as we're talking about multiple chickens). The verb "are" is correct for a plural subject in the present continuous tense ("are laying") and the first "are" (for "chickens" which is plural) is also correct. So there's no subject - verb agreement error.

Answer:

My chickens are more than thirty weeks old, but none are laying eggs yet,"
Mr. Quinn told his neighbor, Avery.
