Example Question #1 : Identifying Subject Verb Agreement Errors
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
My favorite history professor, as well as some of his administrative staff, were asked to resign because fewer students were taking history courses than ever before. No error
were
than
as well as
No error
because
were
In this sentence, the verb does not agree with the subject. The subject "professor" is singular (“as well as some of the administrative staff” is a modifying phrase and doesn’t count), so the correct verb form should be “was,” not “were.”
Example Question #1 : Identifying Subject Verb Agreement Errors
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Stephanie claims that she wants to attend college after graduation, but her poor attitude about studying during senior year do not indicate that she enjoys being a student. No error
to attend
studying
do not indicate
wants
No error
do not indicate
"Her poor attitude about studying" is the subject of this clause, so the verb must agree with the singular subject "attitude." Therefore, the correct verb should be "does"—her attitude "does not indicate."
Example Question #1 : Identifying Subject Verb Agreement Errors
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
James is a proactive police officer, so although the local rebellious teenagers are annoyed by his strict nature, the overall safety of the town have improved drastically since he was hired. No error
No error
are annoyed
have improved
strict nature
so although
have improved
This is an issue of subject-verb agreement within this independent clause: "the overall safety of the town have improved drastically since he was hired." Simplified, the subject is "safety," which is a singular noun, so the verb must also be singular, making "have improved" incorrect and "has improved" the corrected verb.
