Jon's mother did not let him organize a garage sale for the family because she did not like the idea of strangers being able to peruse their many belonging. No error

Question

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

After learning that many experts believe that fear is a healthy evolutionary responses, he felt significantly less afraid of the dark. No error

Answer

"Responses" is incorrect in this sentence as it is part of the phrase "a healthy evolutionary responses." The use of the singular indefinite article "a" means that the noun to which it refers has to be singular for the phrase to be grammatically correct. Changing "responses" to "response" would correct the sentence's error.

Question

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

She runs very fast; sometimes it's quite uncanny. No error

Answer

In the example sentence, the word "fast" is used to describe how the subject of the sentence runs, and the word "very" is being used to modify this description. Therefore, it is correct should use an adverb (for instance swiftly or quickly) in place of "fast." Anytime the manner in which an action is performed is described it is correct to use an adverb, rather than a modified adjective (or any adjective at all). Adverbs describe some of the most important aspects of life, not merely the subject and the verb that subject did, but the way that thing was done.

Question

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

"That blond man is real suspicious," said John. No error

Answer

Here, the world "real" is being used to describe "the blonde man's" level of suspicion, and it seeks to do so by modifying the verb "is." Given that the word in question should be an adverb, you need to replace it with a word such as "really."

Compare your answer with the correct one above

Question

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

The replacement referee is supposedly just as good as the regular Mr. Peterson, but I don't trust them. No error

Answer

In the example sentence, the plural pronoun "them" is used to incorrectly refer to the singular "replacement referee." To fix this sentence, "them" should be switched to "him."

Compare your answer with the correct one above

Although many think of them as incredibly fast, my cheetah runs less than half as fast as my pet falcon flies. No error

Question

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

Which of the two track stars will be quickest than the other? No error

Answer

In the sentence above, the phrase "which of the two track stars" is being modified by the word "quickest." Only two things are being compared, so a comparative adjective should be used, rather than a superlative. Superlatives are used when one item is being distinguished from a group of 3 or more items; comparatives are used to directly compare two items. The best way to correct the sentence above is:

"Which of the two track stars will be quicker than the other?"

Compare your answer with the correct one above

The soldiers may well have been the bravest man in the unit, but that bravery cost him his life. No error

Answer

In the sentence above, the word "soldiers" is being modified by the phrase "bravest man in the unit." Therefore, we know that soldiers should be singular. The best way to correct the sentence above is:

"The soldier may well have been the bravest man in the unit, but that bravery cost him his life."

In this city, the strong survive much more frequent than the weak. No error

Answer

In the sentence above, the word "survive" is being modified by the word "frequent." We know that frequent should be an adverb, rather than an adjective. The best way to correct the sentence above is:

"In this city, the strong survive much more frequently than the weak."

Compare your answer with the correct one above

Question

After practicing for hour on end, Sarah finally managed to perform a perfect kickflip on her skateboard. No error

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

Josie ran as quick as the wind; she knew that she needed to gain some distance now, if she wanted a chance to win the race. No error

Answer

The word "quick" is modifying the verb "ran." Any time a verb is modified, it is correct to use an adverb (in this case, "quickly") rather than an adjective. A runner is quick, but that runner runs "quickly."

Compare your answer with the correct one above

Question

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

Jordan and Marvin’s mother has decided that they will become a lawyer when they grow up, but they seem more artistically inclined. No error

Answer

This sentence's error is a discrepancy in number. Two children are mentioned, "Jordan and Marvin," so logically, they would grow up to become two different lawyers. The sentence uses the singular noun "a lawyer" where it should use the plural noun "lawyers," so "lawyer" is the correct answer.

The corrected sentence reads, "Jordan and Marvin’s mother has decided that they will become lawyers when they grow up, but they seem more artistically inclined."

The corrected sentence reads: "Lewis and Clark, the now legendary explorers of the Louisiana Purchase, were chosen for their scientific knowledge and skills as frontiersmen."

All three of the pumpkins that Gerald entered into the contest became a top-ten winner; needless to say, he was thrilled. No error

Question

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

As part of their development, caterpillars form a cocoon and eventually emerge as moths or butterflies. No error

Answer

This sentence's error is a problem with agreement of plurals. Multiple "caterpillars" should form multiple cocoons, but the sentence uses the singular noun "a cocoon," which doesn't make sense. "A cocoon" is thus the correct answer, and the corrected sentence reads, "As part of their development, caterpillars form cocoons and eventually emerge as moths or butterflies."
