Example Question #1171 : Act English

When the patent on Alexander Graham Bell’s revolutionary invention, the telephone, expired in 1894 thousands of new firms entered the telecommunication industry. Among them were a collection of profitable companies that merged to form what would later become known as The Bell System. The Bell System had amassed such weight in the industry that in 1933, when Congress passed a law declaring phone service a public utility, the Bell System quickly transformed into a monopoly. Lawmakers enthusiastic supported a series of provisions intended to stimulate competition. Appointed as the nation’s sole provider of telecommunication services, widespread criticism about the Bell System began to surface

The Federal Communications Act has so far been highly effective and the industry has grown tremendously as a result. In fact, for the past three years, the profitability of the largest three telecommunication companies has been greater than the largest three automotive companies. The number of calls provided by the top three companies range from five billion to six billion per day. Today, virtually everyone has made a phone call over the course of their lives. Most people do not know, however, that payment for swaths of electromagnetic wavelengths have become commonplace.

One explanation for such high call volume and large profits is that calls are becoming much less expensive for companies to provide, regardless for many large fixed expenses such as communication towers, base stations, and paying for utility poles. Over the last century, telephones had become an important part of modern society. In fact, the cost of delivering one telephone call today is about a thousandth of the cost in the 1950s. The increasing affordability and abundance of phone calls mark the progress made since the time of Alexander Graham Bell and the Bell System.

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

Possible Answers:

ranges

have ranged

NO CHANGE

are ranging

Correct answer:

ranges

Explanation:

The subject of the predicate "range" in the sentence is "number", a singular noun phrase. Thus, the predicate must be in singular form as well, which in this case is "ranges." All of the other answer choices—"range", "have ranged", and "are ranging"—contain predicates in plural form, and are therefore incorrect.

Example Question #21 : Agreement Errors

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

Possible Answers:

are becoming

NO CHANGE

has become

become

Correct answer:

has become

Explanation:

In this sentence, we have the subject "payment" and the predicate "have become". "Payment" is singular, so we need the corresponding predicate to be singular as well. The original text, however, contains a plural predicate ("have become"), as do the answer choices "become" and "are becoming."

To express the statement correctly, the singular subject must be paired with a singular predicate. The only answer choice that does so is "has become." The correct way to express the sentence is therefore "Most people do not know, however, that payment for swaths of electromagnetic wavelengths has become commonplace."

Example Question #22 : Agreement Errors

During the final months of 2007, the prices of basic grains nearly doubled in Northern Africa, Latin America, and much of Asia, the high prices caused a global food crisis. The catastrophe sparked and incited an international debate regarding the licensing of new technologies to developing nations. One economist warned that because of the risk of unforeseen price shocks, officials should proceed very cautiously. The construction of private farms pose a serious financial threat to farmers in the United States; nevertheless, of the five most industrialized nations, the United States exports more crops.  

How do some countries cope with food crises better than others. It is technology that accounts for the majority of the difference. The rate at which countries adopt innovations depends significantly on environmental factors. These environmental factors include climate, soil and elevation. The variability in environment inhibits new technologies from gaining worldwide popularity that are suited for one particular region over another. For example, the pesticides used in Europe are much more acidic than North America. Without the different levels of acidity, pests would prevent the crops to grow.

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

Possible Answers:

are posing

have posed

NO CHANGE

poses

Correct answer:

poses

Explanation:

The subject of the sentence "The construction of private farms pose a serious financial threat to farmers in The United States" is "construction," and the predicate is "pose."

Since "construction" is singular and "pose" is plural, the original text contains a subject-verb agreement error. 

The answer choices "has posed" and "is posing" contain subject-verb agreement errors as well—both are plural predicates when we have a singular subject.

The only answer choice in the singular form is "poses." The correct way to express the sentence is "The construction of private farms poses a serious financial threat to farmers in The United States."

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

Possible Answers:

have been depended

NO CHANGE

are depending

depend

Correct answer:

NO CHANGE

Explanation:

Consider the given sentence: "The rate at which countries adopt innovations depends significantly on environmental factors." We see that the subject is "rate" and the predicate is "depends." Since rate is singular and depends is singular, they match in number (i.e. they "agree"). Thus, no change is necessary, and the correct answer is "NO CHANGE."

Example Question #24 : Agreement Errors

Wolfgang Amadeus Mozart has become wide recognized as one of the most brilliant and influential musicians of all time. At only thirteen years old, he skillfully played several instruments and wrote in a variety of musical genres. Over the past century, his orchestral music, along with his many operas, have delighted audiences around the world. Mozart wrote his music for wealthy patrons and aristocrats, yet even the commoners of the time enjoyed his music. The music of Mozart is richer and more textured than his contemporary, Joseph Haydn.  

The Austro-Turkish War, which began in 1787, prompted the redirection of much of Austria’s resources from arts and music to the military. As a result, Mozart faced financial difficulties. In 1788, he discontinued his public concerts and his income declined. In 1790, hoping to improve his financial situation and circumstances, Mozart toured Berlin and several other cities in Germany. The tours were unsuccessful, however, and did not improve his financial problems.

Scholars have proposed several hypotheses regarding the cause of Mozart’s death, such as influenza, smallpox and meningitisTheir is little physical evidence, however, to support these claims. Mozart's funeral belied the elaborate ornamentation of his music: the ceremony was basic and reserved. In the period following his death, Mozart’s popularity increased significantly. Concert halls throughout Europe featured his music, and composers sought to imitate his style. Modern audiences praise Mozart’s music for its liveliness, expressiveness, and the fact that it is sophisticated.

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

Possible Answers:

are delightling

has delighted

NO CHANGE

delight

Correct answer:

has delighted

Explanation:

The subject of this sentence ("his orchestral music") is singular, but the verb "have delighted" is plural (don't be fooled by the intervening phrase that begins "along with . . .").

To match the singular subject, we need a singular verb. The only answer choice with a singular verb is "has delighted," so it is correct. (The other answer choices have plural verbs).

Example Question #23 : Agreement Errors

“Why Text Messaging is a Good Thing” by Chelci Spiegel (2013)

Many people today think that technology such as text messages and social networking sites are creating distant relationships among people. They say that the relationships are false because face-to-face time is diminishing however, I do not believe this to be the case. These are technologies and technologies are very important tools. That’s just it they’re tools. They can be good or bad depending on how they are used. I believe that text messaging is a benefit to society because it provides fast communication with multiple people unobtrusive conversation and responding time for the receiver.

Because text messaging exists we can tell many people something very important very quickly. It is like an SOS message to whomever needs to know. If I have car trouble I can send a text to my father, brother, and friends all at once. Instead of dialing each number separately and maybe or maybe not getting anyone they all get a message then, I receive help more quickly. A more concrete example is from what I was lost in the woods searching for my horse who was also lost late one evening. I sent out one text message to multiple people and by the time I had found my way back to the truck there were seven friends pulled up with trucks mountain bikes and flashlights to help search for the horses all night.  That is not evidence of relationships distanced by text messaging but brought together.

Because text messaging does not require voice it is far less obtrusive in public places. When I was standing in line at the grocery store one of the ladies were using their phone while waiting for their turn. I heard her entire life story her boy troubles, her work troubles her friend troubles and her money troubles. It was very distracting. With texting people can vent all their frustrations to someone privately. If I am trying to set a date for a barbaque, I can text my neighbor to work out details rather than let the entire store know my weekend plans. Texting is a way to conduct private business in public places.

What would make the underlined portion grammatically correct?

Possible Answers:

would be

will be

was

were all

NO CHANGE

Correct answer:

was

Explanation:

In the phrase "one of the ladies were using," the subject of the independent clause is NOT "ladies," but rather "one." The verb must agree with the subject, and we wouldn't say "one were using" in English, but rather "one was using."

Example Question #25 : Agreement Errors

"The Election of 1800" by Alec Slatky (2013)

The presidential election of 1800 was an unusual and unique contest in American history. The opponents were John Adams and Thomas Jefferson former friends who became rivals. Jefferson had actually been Vice President under Adams, but had not supported the latter’s policies. Jefferson leapt at the chance to unseat his former boss. Adams, too, would have enjoyed spending time on his farm more than dealing with political acrimony. Accordingly, he was too prideful to willingly relinquish his office. So, the two men who were most qualified for the position but least excited to have such a stressful job became the presidential candidates.

The campaign was a bitter partisan one and included numerous personal attacks. Critics called Jefferson a Democratic-Republican radical, he would lead the country down the bloody path of the French Revolution. Jefferson’s allies fired back, painting Adams as an anti-liberty autocrat. Adams was from Massachusetts. Adams even faced opposition from some extremists among his fellow Federalists and thus lacked the party unity required to win the election.

In the end, Jefferson emerged victorious, winning 73 of the 138 electoral votes. Thomas Jefferson was inaugurated as President, and Aaron Burr was inaugurated as Vice President. The election was a milestone in American history: it was the first that shifted control of the White House to a different party, the first with a modern mudslinging campaign, and the first that truly tested whether the new nation would remain united despite all its divisions.

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

Possible Answers:

become

NO CHANGE

was

are

Correct answer:

NO CHANGE

Explanation:

"Became" is correct because it is past tense and agrees with the plural subject ("men"). "Was" is a singular verb that does not agree with the plural subject. "Become" and "are" are in the present tense.

Example Question #26 : Agreement Errors

Communist rule in Poland ended in 1989 and the following year proved disastrous for the Polish economy. Prices rapidly ballooned while incomes dropped. Attempting to find a solution, the Balcerowicz Plan was implemented by Polish officials. The plan liberalized the economy by abolishing price controls, exposing markets to international competition, and it discontinued most industrial subsidiesIn the time of the years following these efforts, economic growth has increased steady

After years of negotiations and economic and political reforms, Poland became a member of The European Union on May 1, 2004. Soon after, Polish officials voted in favor for laws that would eventually mend the unemployment problem in Poland significantly. In fact, the unemployment rate improved for the first time in five years immediately following Poland's membership. The involvement of Poland in the Eastern Bloc is currently greater than the Czech Republic. The passage of two policies regarding energy credits from foreign countries provide evidence of the emergence of Poland in the global economy.

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

Possible Answers:

NO CHANGE

have provided

provides

continue to provide

Correct answer:

provides

Explanation:

The subject of the predicate "provide" is "the passage," which is singular (don't be confused by the intervening plural noun phrases!). To agree with the subject, the predicate must be in singular form as well. This is called "agreement in number." 

"Provide," as in the original text, as well as "have provided" and "continue to provide" are in plural forms, so they are incorrect. The only answer that contains a verb in singular form is the correct answer: "provides." 

 

 

Example Question #27 : Agreement Errors

Speech production is a complicated and complex process, that requires the coordination of three different systems: respiration, phonation, and articulation. A deficit in any of these systems will negatively impact the quality of one’s speech.

We all know that respiration, or breathing, is necessary for life, but have you ever thought about it’s usefulness for speech? Try to talk while holding you’re breath and you will see what I mean. Exhalation provides a stream of air that the next two systems shape into what many people like to call speech.

Phonation happens in your larynx, or voice box. A pair of muscles form a shelf-like structure on either side of your larynx, and this pair of muscles is known as your vocal folds. As you exhale during speech, your vocal fold muscles contract and move towards each other. They vibrate as air passes between them, creating a buzzing sound, and this is a process that is known as phonation. The word “phonation” comes from the ancient Greek word for sound.

Finally, the last stage is articulation. At this final stage, you move your tongue, lips, and jaw to affect the way vibrating air leaves your mouth. For example, when you say the “b” sound, you need to squeeze your lips together to stop the airflow before opening your lips again. For the “v” sound, you touch your top teeth against your lower lip and force air through between your teeth and lip.

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

Possible Answers:

forms

that forms

will form

NO CHANGE

forming

Correct answer:

forms

Explanation:

This contains a subject-verb agreement error. The subject of the verb is pair, which is grammatically a singular noun even though we are talking about two of something. The conjugation of the verb "to form" that agrees with a singular noun is "forms". "That forms" introduces a new error by creating a sentence fragment.

Example Question #831 : Correcting Grammatical Errors

Jeremy had no luck convincing the members of the orchestral committee about his suggestions. He pleaded, cajoled, was begging, and even threatened the committee at various times, but yet despite being the conductor, he couldnt get them to agree to his requests. Despite many attempts, the committee would not listen to him. In the end, he decided to go through with the Christmas concert despite him not having his favorite composer on the program. Afterward, one of his friends, whom was in the audience, came up and asked him why was there no Handel on the program? "I did try" Jeremy replied "but the committee were unanimously against me. I nearly begged them all day to put one piece on the program. But try as I might I could not get a Handel on it."

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

Possible Answers:

the committee had been

the committee was

NO CHANGE

the committee have been

Correct answer:

the committee was

Explanation:

In American English, collective nouns, like "committee," take singular verbs; thus "was" is the conjugation that agrees best.
