Example Question #22 : Other Usage 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.

Example Question #23 : Other 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.

Possible Answers:

NO CHANGE

fond in

fond with

fond about

fond of

Correct answer:

fond of

Explanation:

English features many fixed expressions, such as "figure out" or "look for," in which certain verbs are paired with specific prepositions. In this case, the correct fixed expression is "fond of," so it is the correct answer choice. The other answer choices are distortions of this expression.

Example Question #1761 : Act English

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.

Possible Answers:

in favor of

for favor of

in favor with

NO CHANGE

Correct answer:

in favor of

Explanation:

An idiomatic expression is a fixed phrase in a language, such as "in order to" or "find out." The correct idiomatic expression for this sentence is "in favor of." All of the other answer choices are distortions of this idiom, and are therefore incorrect.

Example Question #25 : Other Usage 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:

In his tiny house at the bottom of the hill,

In his tiny house: at the bottom of the hill,

NO CHANGE

In his tiny house at the bottom of the hill

In his tiny house, at the bottom, of the hill,

Correct answer:

In his tiny house at the bottom of the hill,

Explanation:

The comma in the middle of the underlined portion oddly divides the phrase in two, with no real purpose, as the prepositional phrase can be directly attached to the word "house." The comma should be removed to make the sentence flow more smoothly, making the correct answer choice "In his tiny house at the bottom of the hill."

Example Question #21 : Other Usage 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:

NO CHANGE

move your tongue, lips, and jaw; this affects the way vibrating air leaves your mouth

move you’re tongue, lips, and jaw to affect the way vibrating air leaves your mouth

move your tongue, lips, and jaw to affect the way vibrating air leaves from your mouth

Correct answer:

NO CHANGE

Explanation:

The answer choice "move you’re tongue, lips, and jaw to affect the way vibrating air leaves your mouth" is incorrect because it introduces an error. "Your" is correctly used in the original sentence to indicate possession. If one were to say, "move you are tongue, lips, and jaw," it would not make sense.

The answer choice "move your tongue, lips, and jaw to affect the way vibrating air leaves from your mouth" is incorrect because it adds an unecessary preposition, "from."

The answer choice "move your tongue, lips, and jaw; this affects the way vibrating air leaves your mouth" is grammatically correct, but the original sentence was also correct and more concise.

Example Question #31 : Other Usage 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."

Possible Answers:

of

NO CHANGE

to

on

Correct answer:

of

Explanation:

The preposition "of" is the most appropriate choice to go with the verb "to convince" in this context.

Example Question #381 : Usage Errors

Known as Prohibition the political fight in the United States to ban the sale, consumption, and possession of alcohol took a long time. The official ratification of the 18th Amendment, which banned alcohol, took place in January of 1919, after Nebraska became the 36th state to have its legislature ratify the amendment. The Amendment had first been passed of the United States Senate in 1917, and needed vigorous political action taken by its supporters just to get the necessary 36 states to ratify it. Its official enactment on January 1, 1920 was met with equal amounts of relief and joy by it’s proponents.

Most of them had been fighting to ban alcohol for decades. The American Temperance Society was founding in 1826. Frances Willard had been running the Women’s Christian Temperance Union for decades by the time a national debate was taking place on Prohibition. Carrie Nation had banded together women in the Midwest since the turn of the century to destroy bars and saloons with her trademark hatchet. The Anti-Saloon league organized thousands of everyday Americans to vote against any politician that did not support Prohibition. A burgeoning movement had grown into a legitimate groundswell, by the late 1910s.

After the ratification of the 18th Amendment, few of these supporters thought that it would be the abject failure it turned out to be. Most Americans did not want the absolute ban of all sale, consumption, and possession of alcohol. The most enterprising Americans found many illicit ways to profit from alcohol’s new illegal status. Americans looking for alcohol were seldom out of options, as every corner had either a speakeasy or a bootlegger selling imported or homemade liquor. Criminal organizations grew in strength thanks to profits from illegal booze, and federal agents were hopelessly outmanned of mobsters and thugs. On December 5, 1933, the 21st Amendment to the United States Constitution repealed the 18th Amendment, eliminating the Prohibition of alcohol and turning back the work of all of the Prohibition activists.

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:

founding by 1826

founding under 1826

founded in 1826

NO CHANGE

Correct answer:

founded in 1826

Explanation:

The present participle "founding" is incorrect in this sentence, as it is used with the past tense verb "was." The participle needs to be changed to the past participle form. Therefore, the correct answer choice is "founded in 1826."

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:

passed by the United States Senate in 1917

NO CHANGE

passed in the United States Senate around 1917

passed in the United States Senate by 1917

Correct answer:

passed by the United States Senate in 1917

Explanation:

The prepositional phrase "in the United States Senate" is odd and confusing, as the United States Senate is the body that "passed" the amendment. As such, the preposition should be changed to one that better indicates that the Senate is the body taking action, rather than just the location where something happened. Therefore, the best answer choice is "passed by the United States Senate in 1917."

Possible Answers:

NO CHANGE

hopeless outmanned of mobsters and thugs

hopelessly outmanning mobsters and thugs

hopelessly outmanned by mobsters and thugs

Correct answer:

hopelessly outmanned by mobsters and thugs

Explanation:

The preposition "of" is a strange choice in this sentence, as the "mobsters and thugs" are the ones doing the action the prepositional phrase is tied to. A better choice is to use a preposition that conveys this fact. Therefore, the correct answer choice is "hopelessly outmanned by mobsters and thugs."
