Example Question #205 : Punctuation Errors

"Lincoln as a Child" by Caleb Zimmerman (2013)

 Abraham Lincoln's forefathers were pioneers. People that left their homes to open up the wilderness and make the way clear for others to follow them. For one hundred and seventy years, ever since the first Lincoln came from England to Massachusetts in 1638, he had been moving slowly westward as new settlements were made in the forest. They faced solitude, privation, and all the dangers and hardships that beset those who take up their homes where only beasts and wild men have had homes before; but they continued to press steadily forward, though they lost fortune and sometimes even life itself in their westward progress.

Back in Pennsylvania and New Jersey, some of the Lincolns had been people of wealth and influence. In Kentucky, where the future President was born on February 12, 1809, his parents live in deep poverty. Their home was a small log cabin of the rudest kind, and nothing seemed more unlikely than that their child, coming into the world in such humble surroundings, was destined to be the greatest man of his time and true to his heritage, he also was to be a pioneer—not into new woods and unexplored fields like his ancestors, but a pioneer of a nobler and grander sort, directing the thoughts of people ever toward the right, and leading the American people, through difficulties and dangers and a mighty war, to peace and freedom.

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:

Americans up into

Americans, through

NO CHANGE

American people through

Correct answer:

American people through

Explanation:

"American people through" is the simplest, most concise option. "NO CHANGE" and "Americans, through" have a misplaced comma. The comma introduces a pause between a direct object and prepositional phrase, which is rarely necessary. Answer "Americans up into" uses inaccurate and redundant prepositions (a single preposition would suffice).

Example Question #231 : Correcting Grammatical Errors

While the course appeared hard from the outset, when his report card arrived in the mail, Charlie had discovered that all of his studying had paid off. He had successfully passed Chemistry: his father would be proud. His father, a world-renowned chemist was doubtful that Charlie would pass the class but Charlie was sure that he could do it. He had spent all of the fall semester studying the periodic table, memorizing different measurements and learning the parts of an atom.

That terrible semester culminated in the final exam. The day of the big test, his stomach is a tight knot of nerves. He tried to tell his mother that he was feeling ill but she knew that he was lying.1 He shook as he tried to put on his shoes and socks.He woke up with his fingers tightly gripping the bedspread.3 Sitting on the bus, he could feel himself sweating through his light sweater.4 When Charlie finally arrived at school, he walked into his Chemistry class just as his teacher was passing out the test. “You may now begin,” she said.

With the report card now clenched in his hands in victory, Charlie knew that he could tackle anything to which he put his mind.

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

Possible Answers:

NO CHANGE

chemist, was

chemist;

chemist – was

Correct answer:

chemist, was

Explanation:

The commas in this sentence are used to mark a parenthetical phrase describing Charlie’s father. The first comma is present but you must include a second one after “chemist” to close the parenthetical phrase.

"A Unique Journey" by Jasmine Tilley (2013)

While I was studying abroad in Europe, I had the great opportunity to travel to different countries. For one of my adventures, I chose to travel to Switzerland; however, the classmates I usually traveled with were unable to come with me. I was faced in deciding whether to go alone or not at all. This decision was easy for me, I was not going to pass up the opportunity to see Switzerland!

I first had to board a train from where I was staying in Italy to reach the southern part of Switzerland. Unfortunately, the train workers were on strike that day, so I ended up delayed in Milan for several hours. Soon enough I was on my way again.  However, shortly after I reached the Switzerland border, the train stopped because one of the cars was filled with smoke! I still have no idea what happened, but after a few minutes we were moving again.

Once I finally reached Geneva, I had to walk to find the hostel where I was staying that I had booked. It was night, and I realized that I was truly alone. I did not know another soul in this entire country! This thought was both scary and exciting.

The next day, I walked all around Geneva. Being my own tour guide was a fantastic adventure. I saw all the major sites while also experiencing the culture. There was some sort of marathon going on that day, and there was so much excitement all throughout the city. There were live bands. It even rained off and on. Everything was new and interesting, and I loved it.

That evening, I boarded a train to Zermatt. Prior to this journey, I had no idea that the Matterhorn was an actual mountain! The city of Zermatt was very tiny and had no cars, only small electric vehicles that resembled wind-up toys. The whole city was lit up, and though I was walking to my hostel at night again, I felt very safe. Walking through Geneva at night, though, starkly contrasted it.

The next day, I decided to go skiing on the beautiful, snowy mountains in Zermatt. I rented a pair of skis and spent a few hours skiing in my jeans and coat! It was an amazing experience.

My journey to Switzerland is dear to me not just because of the many beautiful and exciting things I experienced, but also because I was alone. I had the time as well as the quiet atmosphere to absorb and contemplate not just what was going on around me but also what was going on inside myself. I felt changed somehow. I felt stronger and more independent.

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:

Switzerland; however

Switzerland, however

NO CHANGE

Switzerland, however;

Correct answer:

NO CHANGE

Explanation:

In the original sentence, the phrase before the semicolon and the phrase after the semicolon are each already independent clauses. When we use a transitional word like ‘however’ after a semicolon, a comma is always needed.

When we begin a sentence with an adverb, we must place a comma after it. Because the phrase after the underlined portion is a complete sentence, we must also place a comma in between.

Example Question #91 : Comma 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:

goal, Lindquist,

goal. Lindquist

goal Lindquist

goal; Lindquist

NO CHANGE

Correct answer:

NO CHANGE

Explanation:

The phrase "To achieve this goal" is a dependent clause that must be attached to an independent clause (a clause with a subject and a predicate that can stand on its own). Dependent clauses are attached to independent clauses using a comma. Semi-colons can only be used when the pieces before and after the semi-colon are independent clauses. The same is true of period. Adding a comma after Lindquist, as in "goal, Lindquist," creates an unnecessary pause.

This test; which was first administered in 1935, became

This test which was first administered in 1935, became

Correct answer:

This test, which was first administered in 1935, became

Explanation:

The phrase "which was first administered in 1935" is a non-restrictive clause. This means that it is not necessary for the sentence to make sense. Non-restrictive clauses are separated from the rest of a sentence with commas on each end. A good way to identify non-restrictive clauses is to read the sentence without the clause. If it still makes sense, the clause in question is probably a non-restrictive clause.

A semicolon cannot be used because semicolons must separate two independent clauses (two clauses with a subject and a predicate).

Example Question #94 : Comma 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.

Possible Answers:

in 1894, thousands

in, 1894 thousands

NO CHANGE

Correct answer:

in 1894, thousands

Explanation:

An introductory phrase that is longer than three words must be followed immediately by a comma. Since "When the patent on Alexander Graham Bell’s revolutionary invention, the telephone, expired in 1894" is an introductory phrase, it must be followed by a comma. 

 The sentence should therefore read "When the patent on Alexander Graham Bell’s revolutionary invention, the telephone, expired in 1894, thousands of new firms entered the telecommunication industry." Thus, the correct answer is "in 1984, thousands." None of the other answer choices contains a comma immediately following the introductory phrase.

Correct answer:

effective, and

Explanation:

Two independent clauses, such as 1) "The Federal Communications Act has so far been highly effective" and 2) "The industry has grown tremendously as a result," can be combined using a comma immediately followed by a coordinating conjunction (such as "and" or "but"). The correct way to express the sentence is therefore "The Federal Communications Act has so far been highly effective, and the industry has grown tremendously as a result."

The original text contains an error because there is not a comma separating the two independent clauses. The answer choice "effective and," is incorrect because it contains a
comma after, rather than before, the coordinating conjunction. The answer choice "effective, and," is incorrect because it contains an unnecessary comma after the coordinating conjunction.

Example Question #233 : Correcting Grammatical 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:

honors, and,

honors; and

honors and

NO CHANGE

Correct answer:

honors and

Explanation:

We see that the subject of the sentence is "He." The sentence goes on to list two predicates: (1) "graduated with honors" and (2) "began his career as a math teacher." When we have two predicates  (i.e. a "complex predicate") and one subject, the predicates must be separated by a conjunction (such as "and" or "but"), and there should not be a comma between the two predicates.

The correct way to express the sentence is "He graduated with honors and began his career as a math teacher." The correct answer is therefore "honors and." Each of the other answer choices introduces unnecessary punctuation between the two predicates.
