Example Question #1 : Identifying Sentence Errors

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all. 

The recent discovery of the short films and the personal diary of the renowned inventor allow historians to appreciate his genius even more. No error

Possible Answers:

even more

No error

and

allow

of the renowned inventor

Correct answer:

allow

Explanation:

This sentence features an error of subject-verb agreement. The subject of this sentence is singular: "the recent discovery," though the following elaboration of short films and a personal diary can be misleading they do not change the grammatical subject of the sentence. Therefore the verb should be "allows."

Example Question #1 : Identifying Sentence Errors

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Looking down from the summit, Stacy's friends' faces were blurry as they smiled up at her. No error

Possible Answers:

friends'

No error

at her

Looking down

were

Correct answer:

Looking down

Explanation:

"Looking down" is the correct answer. 

The subject of the main clause (after the comma) is "faces" (particularly "Stacy's friends' faces"), which cannot logically be the subject of the first clause. This disagreement creates a dangling clause. It must be the subject (of the whole sentence) who is "looking down," but one can infer that it is Stacy who is at the summit, because her "friends' faces" "smiled up at her."

Possible Answers:

No error

they

to ensure that

it is

interfering with

Correct answer:

it is

Explanation:

In this sentence, the pronoun “it” does not agree in number with its antecedent “efforts.” The corrected sentence reads: While I appreciate your efforts to ensure that the event runs smoothly, they are interfering with my ability to give the artists the flexibility they require.

Possible Answers:

them

makes

emitting from

every time

No error

Possible Answers:

as well as

than 

because

No error

were

Correct answer:

were

Explanation:

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 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

Possible Answers:

wants

studying

to attend

No error

do not indicate

Correct answer:

do not indicate

Explanation:

"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 #2 : Identifying 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

Possible Answers:

have improved 

strict nature

No error

are annoyed

so although

Correct answer:

have improved 

Explanation:

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.

Example Question #2 : 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.

A pair of supportive shoes are important if you are experiencing lower back pain. No error

Possible Answers:

are

No error

supportive

you

are experiencing

Correct answer:

are

Explanation:

The verb "are" agrees with a plural subject, but the subject of this sentence is the singular "pair." Changing "are" to "is" corrects the sentence's error. The corrected sentence reads, "A pair of supportive shoes is important if you are experiencing lower back pain."

Example Question #1 : Identifying Subject Verb Agreement Errors

The paralegal believed that there were an overload of cases in the office, which was creating stress. No error

Possible Answers:

of cases in the office

which

No error

that

were

Correct answer:

were

Explanation:

The verb "were," which is used with plural nouns, corresponds to "overload," which is a singular noun. Therefore, the verb should be "was," to match the singular noun, instead of "were."

Example Question #2 : Identifying 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.

Shana, Joe, and Marcel was incredible in each of their performances and the audience rewarded them through cheers and applause. No error

Possible Answers:

was

through

No error

and

their

Correct answer:

was

Explanation:

Shana, Joe, and Marcel are three nouns grouped together (as indicated by the "and"), and thus are effectively a plural noun. "Was" is used in reference to a singular subject; in this sentence, "was" should be "were" (e.g. "Shana, Joe, and Marcel were incredible . . .").
