He warned the officials that the invasion of new habitats would ruins the city's traditional reputation.

Possible Answers:

would ruining

would ruined

NO CHANGE

would has ruin

would ruin

Correct answer:

would ruin

Explanation:

The subject is "invasion" while the phrase "of new habitats" is only a descriptive prepositional phrase. Because "invasion" is singular, the verb "ruin" must also be singular. Therefore, "would ruin" is correct.

Although the subject "I" is singular, "I" always is paired with the plural form of the verb. Therefore, the correct answer is "NO CHANGE" because the plural form of the underlined verb is "have."

NO CHANGE

Correct answer:

NO CHANGE

Explanation:

The subject, "he," is singular, so the verb must also be singular. Therefore, "he was" is correct, and no change should be made to the sentence.

Example Question #1262 : Act English

“The Dark Ages?” by Matthew Minerd (2016)

There are two different ways to consider the so-called “Dark Ages.” On the one hand, you can think of the period directly after the fall of the Roman Empire, when civilization began to collapse throughout the Western Empire. On the other hand, you can consider the period that followed this initial collapse of society. It is a gross simplification too use the adjective dark to describe the civilization of either of these periods.

As regards the first period it is quite a simplification to consider this period to be a single historical moment. It is not as though the civilization switched off like a lightbulb. At one moment light and then, at the next, dark. Instead, the decline of civilization occurred over a period of numerous decades and was, in fact, already occurring for many years before the so-called period of darkness. Thus, the decline of civilization was not a rapid collapse into barbarism, but instead, was a slow alteration of the cultural milieu of a portion of Europe. Indeed, the Eastern Roman Empire retained much of it’s cultural status during these years of decline!

More importantly, the period following the slow collapse of the Western Empire was much less “dark” than almost every popular telling states. Indeed, even during the period of decline, the seeds for cultural restoration was being sown. A key element of this cultural revival were the formation of monastic communities throughout the countryside of what we now know as Europe. Although these were not the only positive force during these centuries, the monasteries had played an important role in preserving and advancing the cause of culture through at least the thirteenth century and arguably until the Renaissance.

How should the underlined and bolded selection be changed?

Possible Answers:

A key element of this cultural revival was the formation of monastic communities throughout the countryside of what we now know as Europe.

A key element, of this cultural revival, were the formation of monastic communities throughout the countryside of what we now know as Europe.

A key element of this cultural revival was the formation of monastic communities, throughout the countryside of what we now know as Europe.

NO CHANGE

A key element of this cultural revival will be the formation of monastic communities throughout the countryside of what we now know as Europe.

Correct answer:

A key element of this cultural revival was the formation of monastic communities throughout the countryside of what we now know as Europe.

Explanation:

The primary error in this sentence is subject-verb agreement. As written, the sentence has "were" for its main verb; however, subject is singular—"element." Therefore, you will need "was," not "were." Think of the formation, "A key element . . . were." This is clearly wrong! You do not need to change the tense to the future form "will be"; therefore, "was" is the best option among those provided.

“The Dark Ages?” by Matthew Minerd (2016)

How should the underlined and bolded selection be changed?

Possible Answers:

NO CHANGE

Indeed, even during the period of decline the seeds for cultural restoration was being sown.

Indeed, even during the period of decline, the seeds, for cultural restoration were being sown.

Indeed, even during the period of decline, the seeds for cultural restoration were being sown.

Indeed, even during the period of decline the seeds, for cultural restoration was being sown.

Correct answer:

Indeed, even during the period of decline, the seeds for cultural restoration were being sown.

Explanation:

The issue with the sentence as written is the fact that its main verb does not match the number of the sentence's subject. The subject is "seeds." Think of a simple sentence to check the verb: "The seeds were . . ." If you were to say, "The seeds was," you would immediately be aware of the error! The intervening expression "for cultural restoration" can distract you if you are not careful. Now, no additional commas are necessary. The "for" is a preposition, not a conjunction.

Example Question #1263 : Act English

Maybe your thinking of getting a dog; but you are not sure how it will affect your budget. Don’t worry! It’s possible to enjoy the companionship with a dog without spending too much of your precious dollars.

First, you will want to make a list of all the necessary items needed before you bring Fluffy home. Compare costs at different pet stores, grocery stores and big box stores. You will need to buy food, a leash, and purchase toys for your dog.

When it comes to the many dog food choices, you don’t want to just buy the cheaper option. You will want to do some research to see what is healthiest for your dog! One of the best ways to save money on dog food is to buy it in bulk.

Don’t forget to plan for some other big expenses, the vet consultation, wellness exam, and any treatments your dog needs. When you bring your pet to the vet, they may need shots, which can vary for price. Call different clinics in the area and ask how much they charge for the standard immunizations? You might find that there is a lot of differences between offices.

The key to sticking to your budget is planning everything out! With good preparation and organization, a dog will not cost you more money than you planned for.

Choose the answer that best corrects the bolded and underlined portion of the passage. If the bolded and underlined portion is correct as written, choose "NO CHANGE."

Possible Answers:

You might find that there are a lot of differences between offices.

You might find that there are a lot of difference between offices.

You might find that there are a lot of differences between office.

NO CHANGE

You might find that there's lots of differences between offices.

Correct answer:

You might find that there are a lot of differences between offices.

Explanation:

This question asks you to correct an error in subject-verb agreement. The noun, "differences," is plural, so the verb must also be plural to agree. The correct plural form of the verb "to be" is "are."

Example Question #131 : Word Usage Errors

“On the Nature of Belief”

Belief and faith often are critiqued in a scientific culture.  It can seem that mere belief is a replacement for science made available to soothe the ignorant masses.  There is some truth to such accusations, and many people do use belief as a screen to cover their own ignorance about the truths of reality.  Everyone should be aware, however, that almost every single human being have these kinds of “blind spots.”  We all live with many things that we merely believe, all of which are so central to ones world view.

Even if we set aside all such types of beliefs, there still remains a broad terrain of human life in which faith and belief remain—even if we ignore all religious matters whatsoever.  Imagine the scientist who’s work on brain neurons depends upon many discoveries made by many other people.  Yes, if it were possible, it would be better for such a person to know all of the details that they accept merely at the word of other scientists.  In all cases, seeing directly is more fulfilling than merely hearing about something.

However, is the scientist better off when he or she knows only what they have experienced directly.  Although it is preferable that he or she knows such facts. However, it is impossible to investigate everything.  Sometimes, one must extend one’s own vision with the vision of someone else.  In a way, the person who thus “takes it on faith” gains a further vision.

Such faith always relies upon the credibility of the person who shares the experience, of course.  For one person to believe on faith what another person says, it is presupposed that the other person is not a liar and actually could have experienced the matter in question.  This means that even the “scientific believer” must take the risk of placing credibility in someone who has witnessed things that he or she has not seen.  While this does not vindicate every kind of faith that people have had, it does provide a telling sign that faith, as such, is not always the refuge of the ignorant.  Indeed, it is an important part of all of our lives, even the lives of scientists, who’s daring and investigative work is rarely criticized as being a refuge for ignorance!

Choose the answer that best corrects the bolded and underlined portion of the passage. If the bolded and underlined portion is correct as written, choose "NO CHANGE."

Possible Answers:

that almost every single human being have these kinds of, “blind spots.” 

NO CHANGE

that almost every single human being have this kind of “blind spot.” 

that almost every single human being have these kinds of, “Blind spots.” 

that almost every single human being has these kinds of “blind spots.” 

Correct answer:

that almost every single human being has these kinds of “blind spots.” 

Explanation:

To help find an error like the one in this sentence, it is easiest  to cut back some of the extra verbiage. This will help you find your subject, which is "human being" in the singular. (The sentence itself refers to "every single" human being. This should help!) This means that you need a singular form of the verb. Hence, it should be, "Human being . . . has." You are likely to be confused because this verb is followed by the object in the plural, namely "these kinds..." Remember, the verb matches the subject not its object!

Example Question #923 : Correcting Grammatical Errors

Belief and faith often are critiqued in a scientific culture.  It can seem that mere belief is a replacement for science made available to soothe the ignorant masses.  There is some truth to such accusations, and many people do use belief as a screen to cover their own ignorance about the truths of reality.  Everyone should be aware, however, that almost every single human being have these kinds of “blind spots.”  We all live with many things that we merely believe, all of which are so central to ones world view.

Choose the answer that best corrects the bolded and underlined portion of the passage. If the bolded and underlined portion is correct as written, choose "NO CHANGE."

Possible Answers:

NO CHANGE

types of beliefs, they're still remain a broad terrain

types of beliefs, they're still remains a broad terrain

types of beliefs, there still remain a broad terrain

types of beliefs, their still remains a broad terrain

Correct answer:

NO CHANGE

Explanation:

No change is necessary for this sentence, though it is tempting to think that one is needed. Because we were just talking about "beliefs," you might be tricked into thinking that the subject of the sentence is plural. This is not the case. The subject of the main clause is "a broad terrain." To help you see the proper verb form, reorder the sentence to read, "A broad terrain remains." You wouldn't say, "A broad terrain remain." Therefore, leave the sentence as written, for its form is correct!

Example Question #1266 : Act English

In legends and stories passed from generation to generation, people have spoken, and written about the mysterious glimmering beauty of the morning star. This twinkling body of light goes under many names. Some call it the morning star, some have called it the evening star, and some call it the planet Venus. The reason we see the morning star is because the planet Venus is somewhere to the left side relative to Earth. As the Earth rotates and the sun "rises" east of where you are positioned, the morning star also catches the sun's light and the reflection of the light off the planet's surface is what we see in the morning. When the planet has moved to the right of the sun, the opposite occurs, so we only see the reflection off the planet in the evening as the sun sets. As the planet slowly rotate around the sun, it is possible that the planet could be on the left side in the morning and then the right side in the evening, causing us to see it as both an evening and morning star.

Choose the answer that best corrects the bolded portion of this passage. If the bolded portion is correct as written, please select NO CHANGE. 

Possible Answers:

rotates around

are rotating around

rotating around

rotated around

NO CHANGE

Correct answer:

rotates around

Explanation:

The subject to this verb is "planet." Because "planet" is the subject and is a singular subject, the verb must also be singular. Therefore, the correct answer is "rotates," the singular form of the verb.
