Example Question #164 : 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.

I believe that your being difficult just for the sake of being difficult; I would appreciate it if you would stop. No error

Possible Answers:

No error

I believe that

being difficult;

you would stop.

your being

Correct answer:

your being

Explanation:

“You're” is a contraction meaning you are. “your” indicates possession when using the second person pronoun you. This sentence needs a verb, not a possessive pronoun, so the portion of the sentence that needs to be corrected is, "your being."

Example Question #165 : 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.

I bought a lot of you're daughter's Girl Scout cookies last week, and I would appreciate it if you would buy a wreath for my son. No error

Possible Answers:

No error

you're daughter's

you would buy

I bought 

last week, and

Correct answer:

you're daughter's

Explanation:

“You're” is a contraction of "you are." “Your” indicates possession when using the second person pronoun you. In the sentence above, clearly "you are" would be a very strange and grammatically incorrect choice, so "you're" has to be the error in the example.

Example Question #166 : 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.

You need to be sure to feed the dog its' raw meat. No error

Possible Answers:

meat.

No error

Its'

to feed

to be

Correct answer:

Its'

Explanation:

This sentence features a simple error of apostrophe placement. The apostrophe in "its'" should be moved before the "s" in order to indicate singular possession. The rest of the sentence is correct as written.

Example Question #167 : 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.

Possible Answers:

were sure that

a number

No error

it's

The very old boat

Correct answer:

it's

Explanation:

“It’s” is a contraction meaning it is or it has. “Its” indicates possession when using the third person pronoun it. In this sentence, it would not make sense to say "a number of leaks in it is keel," so we know that "it's" should be replaced with "its."

Example Question #168 : 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.

Correct answer:

Explanation:

“It’s” is a contraction meaning it is or it has. “Its” indicates possession when using the third person pronoun it. The portion of the sentence that needs to be corrected is, "its"

Possible Answers:

No error

water?

your

You look

Correct answer:

The team leaders began the process of reforming the organizations structure as soon as the report was issued.

Possible Answers:

reforming the organization's structure

reforming the organizations structures

reforming the organization's structure

reformation the organization's structure

reformed the organization's structure

Correct answer:

reforming the organization's structure

Explanation:

The underlined phrase in the sentence has a problem with the word "organizations." The construction of the sentence indicates it needs to be the possesive form, describing the "structure" of the "organization." The correct answer choice is "reforming the organization's structure."

Example Question #1 : Identifying Quotation Mark Errors

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

Liam told his study group that "he needed to take a break from studying," so the group's members all decided to get sandwiches before beginning to take notes on the textbook's next chapter. No error

Possible Answers:

No error

"he needed to take a break from studying,"

the group's members

before beginning to take notes on

the textbook's

Correct answer:

"he needed to take a break from studying,"

Explanation:

This sentence incorrectly uses quotation marks to set off an indirect quotation from the sentence when no quotation marks are needed. If the sentence said "Liam told his study group, 'I need to take a break from studying,'" then quotation marks would be necessary. However, because the sentence is indirectly telling us what Liam said, and not giving us his exact words, no quotation marks are needed.  Removing the quotation marks around "he needed to take a break from studying" would correct the sentence's error.
