Example Questions

Example Question #1 : Identifying Sentence Fragment And Sentence Combination Errors

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

In particular, the audience’s worry that the vicious dogs might biteNo error.

Possible Answers:

vicious

might bite

No error.

the audience's worry

In particular

Correct answer:

the audience's worry

Explanation:

This sentence is a fragment, because it does not have a main verb. Changing the noun phrase “the audience’s worry” to a noun and verb fixes this nicely: "In particular, the audience worried that the vicious dogs might bite."

Example Question #1 : Identifying Sentence Fragment And Sentence Combination Errors

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

Paul was frustrated because his phone was not working, service was inconsistentNo error.

Possible Answers:

inconsistent

his

No error.

working, service

frustrated because

Correct answer:

working, service

Explanation:

This sentence is a run-on. There are two independent clauses separated only by a comma. Change that comma to a semicolon to fix the problem: "Paul was frustrated because his phone was not working; service was inconsistent."

Example Question #2 : Identifying Sentence Fragment And Sentence Combination 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 museum is hosting a Georgia O'Keefe exhibit until January, we should go this weekend. No error.

Possible Answers:

this

No error.

January, we

Georgia O'Keefe

is hosting

Correct answer:

January, we

Explanation:

This sentence has a comma splice. This is when two independent clauses (clauses which can stand on their own as complete sentences) are separated only by a comma. A semicolon works well here. The corrected sentence reads, "The museum is hosting a Georgia O'Keefe exhibit until January; we should go this weekend."

Example Question #3 : Identifying Sentence Fragment And Sentence Combination Errors

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

Due to global temperature increases, and the polar ice cap is melting at an alarming rate. No error

Possible Answers:

No error

global temperature increases

is melting

and 

alarming

Correct answer:

and 

Explanation:

This sentence is not coordinated correctly. The first clause explains why something is happening, so it shouldn’t be connected to the main clause with an “and.” The corrected sentence reads, "Due to global temperature increases, the polar ice cap is melting at an alarming rate."

Example Question #4 : Identifying Sentence Fragment And Sentence Combination Errors

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

Enjoying the sensation of standing in the warm rain and listening to it hit the pavement. No error

Possible Answers:

rain and listening

it

sensation of 

No error

Enjoying

Correct answer:

Enjoying

Explanation:

This sentence is a fragment because it does not have a subject. Instead of starting out with the gerund ("-ing" verb used as a noun) “enjoying,” we need a subject and a verb that agrees with it. One example of how to correct this sentence would be, "I enjoy the sensation of standing in the warm rain and listening to it hit the pavement."

Example Question #5 : Identifying Sentence Fragment And Sentence Combination 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 cafeteria that was serving "seafood surprise" for lunch and subsequently not attracting many customersNo error

Possible Answers:

"seafood surprise"

subsequently

that

No error

not attracting many customers

Correct answer:

that

Explanation:

This sentence is a fragment; read it out loud and you will hear that it sounds incomplete. This happened because the "that" turned the main part of the sentence into a modifying phrase. Take this out to fix the fragment: "The cafeteria was serving "seafood surprise" for lunch and subsequently not attracting many customers."

Example Question #6 : Identifying Sentence Fragment And Sentence Combination Errors

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

Virtue is, in many ways, a foreign idea to him, every kind gesture he thinks he knows is proven false. No error

Possible Answers:

No error

false.

him, every

Virtue

, in many ways,

Correct answer:

him, every

Explanation:

In this sentence, the independent clauses "Virtue is, in many ways, a foreign idea to him" and "every kind gesture he thinks he knows is proven false" are linked with a comma. This is called a comma splice and should be avoided. Replacing the comma with a semicolon fixes the error.

Example Question #7 : Identifying Sentence Fragment And Sentence Combination Errors

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

Rodrigo will always be wealthy. Even if he were to unknowingly live out the prophecy. No error

Possible Answers:

No error

wealthy.

prophecy.

Always

unknowingly

Correct answer:

wealthy.

Explanation:

"Even if he were to unknowingly live out the prophecy," is a dependent clause. It could be combined with the sentence before it, if a comma were placed after "wealthy," the period after "wealthy" is incorrect.
