Example Question #102 : Usage Errors

In 1929, E.F. Lindquist, a professor in the University of Iowa College of Education, began designing tests for the Iowa Academic Meet. The purpose of the meet was to identify exemplary high school students. Test-takers began with a first round of testing. This round occurred during the school day and covered ten core academic subjects. Students who scored well in the first round participated in district-level tests that were more difficult. High-scorers from the second round participated in a third round of testing. The top ten students in each subject area were rewarded with medals at a banquet. Although the test was a success, Lindquist wanted to reduce the competitive aspect of the test. To achieve this goal, Lindquist renamed the test the Iowa Every-Pupil Achievement Testing Program.

The tests popularity provided Lindquist with the opportunity to study how to best write, administer, and score a standardized test. However, Lindquist was not yet satisfied. He grew concerned that the test focused too much on rote memorization of content rather than on skill development. Lindquist began to work on a test for middle school students that would test skills. This test which was first administered in 1935 became known as the Iowa Test of Basic Skills. In 1942, the Every-Pupil test is discontinued and replaced with the Iowa Tests of Educational Development. As Lindquist had hoped, this test focused on testing skills rather than pure content memorization.

By the late 1950s, Lindquist had gained significant renown in the world of standardized testing, so he became involved in the process of developing a college admissions testing program. Although the SAT had been a commonly used admissions test since 1926, it was primarily marketed in the northeast and used as an admissions test for universities in that region. Schools outside this area used a variety of different tests that covered different content and was administered at different times. This led to unreliable results.

In 1958, that a standardized, national test be developed was proposed by Lindquist. He also hoped that, unlike the SAT, the new test would measure academic achievement so that it could be used to gauge each student’s level of preparation for college-level work.

Lindquist and a man named Ted McCarrel began developing the new test. One of McCarrel's main jobs was contacting admissions officers and convincing schools to use the new test. However, like the SAT, the ACT began as a regional test. Unlike the SAT, however, it was primarily used in the Midwest. With time and effort, the test became more popular in other parts of the country.

In 1959, the ACT was administered for the first time. The test was similar to the Iowa Tests of Educational Development. It consisted of four parts; English, math, social studies, and natural science. The social studies and natural science portions required students to interpret readings from each field; thus, Lindquist was able to maintain his goal of testing skills rather than memorized facts. Students had forty-five minutes to complete each section of the test. The ACT quickly became a staple of the college admissions process. In the first year, 132,963 students took the test, and that number grew in subsequent years.

Today, many colleges and universities in the U.S. accept ACT results from students applying for admission. So, don't worry! I'm sure your college will accept it too!

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:

discontinues and replaces with

was discontinued and is replaced with

NO CHANGE

was discontinued and replaced with

is discontinued and was replaced with

Correct answer:

was discontinued and replaced with

Explanation:

Because the passage refers to the year 1942, which is in the past, the past tense of the verb is needed here. Furthermore, the rest of the passage is written in the past tense, so for the sake of consistency, the past tense should be used here. The verb in this sentence ,"is," should be changed to the past tense form "was."

Example Question #103 : Usage Errors

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:

NO CHANGE

have become

has become

are becoming

is becoming

Correct answer:

have become

Explanation:

We notice that the sentence begins with "Over the past half-century", which is a context clue  telling us that some event started in the past and persists until today. The original text contains a tense error: "had become" is in the past perfect, a tense reserved for past events that have stopped or were interrupted. The correct tense for a verb that started in the past and persists until today is the present perfect (e.g., "has eaten", "have seen"). In this case, the  present perfect is "has become," the correct answer.

Although "has become" correctly uses the present perfect tense, it is incorrect because it uses singular rather than plural form, and the subject of the verb ("telephones") is a plural noun.

The answer choice "is becoming" is incorrect for two reasons: 1) it does not use the present perfect tense, and 2) it is in singular rather than plural form.

Example Question #104 : Usage Errors

Alfred Tarski, born on January 14, 1901, became known during his lifetime as a brilliant mathematician and teacher. He is best known for proving several advanced geometric theorems. By the time Tarski moved to the United States, much of Europe has already fallen into the grips of World War II. Hundreds of mathematical problems were solved by Tarski.

Tarski enrolled in Warsaw University in 1920. Originally wishing to study biology, mathematics was the subject in which Tarski ultimately excelled. He graduated with honors, and began his career as a math teacher. A true mathematical virtuoso, Tarski was concerned with neither the application of his research nor publishing his findings.   

Discoveries made by Tarski influenced the work of one of the world’s greatest physicists, Albert Einstein. Einstein and Tarski had many similar interests in common. Unlike Albert Einstein, however, Tarski was especially fond for pure mathematics. Although Tarski and Einstein were contemporaries, Einstein was the most prolific writer of the two.

In 1929, Tarski married his co-worker, Maria Witkowska. An affinity for mathematics ran in the family. Tarski even admitted that his wife knew more about algebra, geometry and trigonometry than did he. Tarski's two children, Jan, and Ina, grew up to be prominent mathematicians themselves; however, neither Jan nor Ina have received a great deal of international attention.

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:

had already fallen

already falls

to fall

NO CHANGE

will have already fallen

Correct answer:

had already fallen

Explanation:

When describing two past events, one of which took place before the other, the appropriate tense for the chronologically earlier event is the past perfect (e.g., "had eaten" or "had heard"). 

The sentence mentions two past events: 1) Tarski's move to the US and 2) much of Europe falling into the grips of WWII. The "already" tells us that Europe fell into the grips of WWII before Tarski moved. The sentence should therefore read "By the time Tarski moved the United States, much of Europe had already fallen into the grips of World War II."

The answer choice "has fallen" is incorrect because it uses the present perfect, a tense reserved for continuous past events that persist up until and including the present.

The answer choice "will have fallen" is incorrect because it uses the future perfect, a tense reserved for continuous events that are going to happen in the future.

The answer choice "to fall" is incorrect because it is an infinitive and does not convey either a specific or relative time at which the falling occurs.

Finally, "falls" is incorrect because it uses the present tense to describe the past event of much of Europe falling into the grips of WWII.

Example Question #84 : Verb Formation 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:

NO CHANGE

was actually being

is actually

has actually been

Correct answer:

NO CHANGE

Explanation:

"had actually been" is correct because it is in the correct tense.  The tense needs to indicate the past, because the event takes place before 1800, and this past perfect tense does so;  "is actually" indicates the present tense, "has actually been" indicates the recent past, and "was actually being" is unnecessarily wordy.

Example Question #1495 : Act English

The ship was having trouble again. Engineer James Ferguson couldn't figure out why the super-duper drive engine kept breaching. Every time he had fixed it, something seemed to go wrong again. He had a capable crew and he was friendly with all of them: but the aliens who had evolved from deer rather than from apes as humans hadhad some problems when it came to fixing things. Their strong arms ended in tiny predicative hooves that sometimes makes it difficult for them to hold large objects. They were good at problem-solving though and he did like them a lot. The nearest one gave him a dough-eyed look of sympathy—appropriate, given her gender. He looked back at the breaching drive engine and sighed. "Once more into the breach, deer friends" he announced.

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:

is fixing

NO CHANGE

has fixed

fixed

Correct answer:

fixed

Possible Answers:

has

have

would have been having

NO CHANGE

Correct answer:

NO CHANGE

Explanation:

The sentence starts off in the past tense; we can tell this because of its use of the past tense verbs "had" and "was." There's no reason presented as to why the underlined verb "had" should not be in past tense as well, so it is correct as written.

Example Question #111 : Usage Errors

Margaret Mitchell the writer was having a horrible day. She just completed her latest novel when the tornado sirens went off. Fast, she rushed down into the basement, barricaded the door, and she sat in a corner of the dank dusty room to wait for the storm to pass. The winds howled noisy and increased in intensity until it sounded like the tornado was right above her. Suddenly, a gigantic bang echoed throughout the basement and Margaret dropped to the floor in terror. Then just as suddenly the noise vanished. Margaret got up and dusted her off before moving hesitantly toward the basement door. She opened it, and found the house above her was completely gone. Despite the horror of the site, she sighed and muttered, "Oh, well." A neighbor came running up to her and said, "Margaret! Thank goodness your alive! But what happened to your house, and what about your new book?" Margaret gave a rueful smile and replied, "Oh, that's Gone With The Wind."

Possible Answers:

completed

just had completed

NO CHANGE

had just completed

Correct answer:

had just completed

Example Question #1152 : Correcting Grammatical Errors

The house stood, at the bottom of a hill, making it hard to see from the street. The owner wants it that way, as he had no use for any of his neighbors. “Nosy sneaks and cheats” he would to say to his son. Not that his son ever really listening. The old man did not see him very much, either at his home or going anywhere else. Every time he did see him, his son would just complain about how his house was dark musty, and filthy. The old man did not need such criticism, especially from only his blood relative. He had lived in that house for fifty years, and planned to live there as long as he possibly could. While he lived there, his neighbors would never see him or his house if he could help it. He could take care of him, and steadfastly refused to allow anyone to help. In his tiny house, at the bottom of the hill, the old man was content to be alone, and believed he was living perfect.

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 owner wanting it that way

The owner wanted it that way

The owner wants that way

NO CHANGE

Correct answer:

The owner wanted it that way

Explanation:

The use of the present tense verb "wants" in the underlined portion is incorrect, as both the preceeding sentence and the second clause of the same sentence use past tense verbs. A passage should always keep the same verb tense when describing action that takes place at the same time. "The owner wanted it that way" is the only answer choice that properly uses a past tense verb.

Example Question #63 : Verb Tense Errors

The bayou was quiet, except for the sounds of insects, water and the occasional alligator. Jim was cleaning his blade, which he had recently used to dispatch one of the undead. His partner Bill and him had come out to the bayou for their nightly patrol and they had found a nest of the undead by an old abandoned dock.

"Hey, Bill!," he shouted gleefully, mindless of whether the noise would attract more undead. "Where'd you go, man?"

A noise to his left had startled him. He turned quick and saw the man who had been closest to him than a brother for the past six months walking slowly toward him.

"Whew," he said: "there you are." He went back to cleaning his blade. "I thought one of those things had got 'cha."

Standing in the dark, the light of the moon did not reach his partners face. The sudden silence caused Jim to look up again. "What's the matter with you, Bill?"

It was only when the thing that was once Bill stepped into the light and Jim saw the fresh bite on it's newly dead face that he realized what the matter was.

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:

was startling him

NO CHANGE

has startled him

startled him

Correct answer:

startled him

Explanation:

The story is being told both in past tense to describe the events that have just happened and in past perfect to show the events that happened before those other past events. Jim being startled is in simple past tense to show that it just happened.
