Example Questions

Example Question #1021 : 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.

Even though the runners were clearly exhausted and had even begun to limp, the coach wouldn’t let them rest until they had ran the entire course. No error

Possible Answers:

had even begun

they had ran

No error

limp,

Even though

Correct answer:

they had ran

Explanation:

Here we have an error with the present perfect. The correct conjugation is “they had run,” not “they had ran.”

Example Question #1022 : 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.

Although the weather habecame terribly cold and dry of late, a warm front with showers was on its way. No error

Possible Answers:

of late

had became

No error

Although

was

Correct answer:

had became

Explanation:

The error here lies in the verb agreement. Because the past participle is called for, the verb should employ both the past form of the verb "have" (i.e., "had," as it does) and the present form of the verb "become" (i.e., "become," as it does not). Thus, the past form of "become" is incorrect and must be changed to the present form.

Example Question #1023 : Identifying Sentence Errors

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

We anticipated that John and Michael would want to quickly solve the assigned problems so that they could go home and rest. No error

Possible Answers:

quickly

problems

anticipated

No error

and 

Correct answer:

quickly

Explanation:

The phrase "to quickly solve" is an example of what is called a split infinitive: the infinitive form of the verb ("to solve") interrupted by another word. In general, modifiers should not interrupt the infinitive structure. The phrase should be corrected to move the word "quickly" to a new position in the sentence (eg., "...John and Michael would want to solve the assigned problems quickly...").

Example Question #151 : Identifying Punctuation 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 eldest male dog became awfully selfish during feeding time, he would not even let his own pups get a scrap of food. No error

Explanation:

Two independent clauses that can each stand alone must be separated by either a period or a semicolon, or connected by a comma followed by a conjunction. Because this sentence doesn't include a conjunction like "and" after its comma, it is incorrect. (This error, where two independent clauses are incorrectly connected by a comma, is known as a "comma splice.")

Example Question #1 : Identifying Punctuation Errors: Commas

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

Anna, questioning her decision, looked to her brother, however he wouldn't meet her eye. No error

Possible Answers:

decision, looked

No error

Anna, questioning

brother, however

wouldn't meet

Correct answer:

brother, however

Explanation:

The clause, "however, he wouldn't meet her eye," is an independent clause and must be separated by a semicolon or a coordinating conjunction.

Example Question #1 : Identifying Punctuation Errors: Comma Splices

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

I stayed up late last night baking chocolate chip cookies, this morning when I woke up the house smelled so good that it made me hungry. No error

Possible Answers:

baking

cookies,

stayed up late

No error

smelled so good

Explanation:

This is a run-on sentence. The two independent clauses need to be split into two separate sentences, or separated by a semicolon.

Example Question #2 : Identifying Punctuation Errors: Comma Splices

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

Car, bicycle, and bus are the only means of transportation in this city, there is no metro system available yetNo error

Possible Answers:

Correct answer:

city, there

Explanation:

A comma should only be used to separate an independent clause from a dependent clause: here it is separating two independent clauses, so a period or semi-colon is more appropritate.

Example Question #3 : Identifying Punctuation Errors: Commas

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

The kids at the pumpkin patch screeched and spun around in circles all day, they bothered their teacher tremendouslyNo error

Possible Answers:

No error

screeched

in circles

day, they

tremendously

Correct answer:

day, they

Explanation:

This is an example of a comma splice. The two independent clauses should be separated by a period, a semi-colon, or a comma and a conjunction, not by just a comma, which is used to separate independent and dependent clauses.

Example Question #161 : Identifying Punctuation Errors

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

How many times do I have to tell you, you have to tie the garbage bags securely or we will have animals in our trash. No error

Possible Answers:

How many times

you, you

securely

we will have

No error

Correct answer:

you, you

Explanation:

The first clause of this sentence, "How many times do I have to tell you," is actually a rhetorical question.  It is an independent clause and therefore must be separated with stronger punctuation than just a comma.  In this case, it would be appropriate to set it off as its own sentence, ending in a question mark, but regardless, the comma splice in "you, you" is what makes this sentence ungrammatical.

Example Question #4 : Identifying Punctuation Errors: Comma Splices

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

Baking soda, also known as sodium bicarbonate, is a truly useful substance, it can be used for cooking, baking, and cleaning. No error.

Possible Answers:

is

truly useful

No error.

substance, it

soda, also known

Correct answer:

substance, it

Explanation:

A comma cannot be used by itself to join two independent clauses, so "substance, it" contains this sentence's error. The first independent clause in this sentence is "Baking soda, also known as sodium bicarbonate, is a truly useful substance." The second independent clause is "It can be used for cooking, baking, and cleaning." Two independent clauses can be joined into a compound sentence in one of two ways: by using a comma followed by a conjunction or by using a semicolon.
