Example Question #12 : Semicolon Errors

Adapted from The Origin of Species by Charles Darwin (ed. 1896)

Look at a plant in the midst of it’s range. Why does it not double or quadruple its numbers? We know that it can perfectly well withstand a little more heat or cold, dampness or dryness, for elsewhere it ranges into slightly hotter or colder, damper or drier districts. In this case, we can clearly see that if we wish in imagination to give the plant the power of increasing in number, we should have to give it some advantage over its competitors, or over the animals of the wild that prey on it. On the confines of its geographical range, a change of constitution with respect to climate would clearly be an advantage to our plant; but we have reason to believe that only a few plants or animals range so far, that they are destroyed exclusively by the rigor of the climate. Not until we reach the extreme confines of life, in the Arctic regions or on the borders of an utter desert, will competition cease. The land may be extremely cold or dry, yet their will be competition between some few species, or between the individuals of the same species, for the warmest or dampest spots.

Hence we can see that when a plant or animal is placed in a new country amongst new competitors, the conditions of its life will generally be changed in an essential manner, although the climate may be exactly the same as in its former home. If it’s average numbers are to increase in its new home, we should have to modify it in a different way to what we should have had to do in its native country; for we should have to give it some advantage over a different set of competitors or enemies.

It is good thus to try in imagination to give to any one species an advantage over another. Probably in no single instance should we know what to do. This ought to convince us of our ignorance on the mutual relations of all organic beings; a conviction as necessary, as it is difficult to acquire. All that we can do is to keep steadily in mind that each organic being is striving to increase in a geometrical ratio; that each at some period of its life, during some season of the year, during each generation or at intervals, has to struggle for life and to suffer great destruction. When we reflect on this struggle, we may console ourselves with the full belief that the war of nature is not incessant, that no fear is felt, that death is generally prompt, and that the vigorous, the healthy, and the happy survive and multiply.

What would be the best syntactic form of the boldfaced and underlined selection “ratio; that”?

Possible Answers:

NO CHANGE

ratio and, likewise, that

ratio that

ratio and

Correct answer:

ratio and, likewise, that

Explanation:

Cut out all of the unnecessary portions of this sentence in order to see the basic structure being expressed:

"All that we can do is to keep in mind that each organic being is striving to increase . . . ;that each at some period of its life . . . has to struggle."

The idea is that we must bear in mind that each organic being is struggling to increase in numbers and that it is also struggling against destruction. The semicolon confuses this greatly. As it is written, the portion following the semicolon is a fragment. It would be better to express this just as we did above, using "and that." Among the answers, the best option not only does this but adds the adverb "likewise" in order to show the reader that what follows is a second point to be kept in mind.

Example Question #41 : Correcting Grammatical 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.

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:

Omit the underlined portion

NO CHANGE

messaging, exists we can tell

exists, we can tell

messaging exists; we can tell

Correct answer:

exists, we can tell

Explanation:

Any dependent clause that begins a sentence must be separated from the rest of the sentence by a comma. "Because" is the beginning to a dependent clause: the phrase following "because" needs the rest of the sentence to be a complete sentence with a proper subject and verb, but the rest of the sentence does not need the part that begins with "because."

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:

diminishing however I do

diminishing, however, I do

diminishing; however, I do

NO CHANGE

diminishing, and however, I do

Correct answer:

diminishing; however, I do

Explanation:

"They say that the relationships are false because face-to-face time is diminishing however, I do not believe this to be the case." This is a sentence comprised of two complete sentences ("They say that the relationships are false because face-to-face time is diminishing" and "however, I do not believe this to be the case.") that are separated by the transition word "however." When there are two complete sentences separated by a transition word, that word must be preceded by a semi colon, especially if either sentence already has a comma in it.

Example Question #381 : Act English

"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.

Which of the following would NOT be an acceptable alternative for the bolded selection?

Possible Answers:

President; Aaron

NO CHANGE

President. Aaron

President, Aaron

Correct answer:

President, Aaron

Explanation:

"President, Aaron" is correct because it is a run-on sentence; it connects two full sentences without a period, semicolon, or conjunction. Each of the other choices contains one of those three options.

Example Question #21 : Punctuation Errors

As the class entered the museum, Ms. Johnson noticed that two of her students had fallen behind the group. After all of the tickets had been secured, she approached the two girls, saying: “what on Earth is causing you to go so slow?” The taller girl, whose name was Ashley, was the first to respond:

“Veronica and I were just discussing something very private. Nobody can hear what her and I are discussing.”

“Well, Ashley, I think that our tour guide, Dr. Mitchell, will be offended by your behavior. You and Veronica should find separate places in the group and you should pay attention to him and me.”

The two girls reluctantly joined the rest of the class. Ms. Johnson looked to see if another student was out of their place, but everything seemed to be in order. The tour guide, Dr. Mitchell, introduced himself to the class: 

“Hello everyone! My name is Dr. Mitchell. I’m so glad that you have all come to the Museum of Natural History today; I think you’ll really enjoy our exhibits, which have been curated with the utmost care. The museum has three distinct types of exhibitions. Permanent exhibitions, temporary exhibitions, and space shows. The permanent exhibition and the space show is always available for viewing, but the temporary exhibition changes seasonally.“

Having finished his introduction, the permanent exhibition was the first thing that Dr. Mitchell showed to the class.

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:

today I think you'll really enjoy

today, I think you'll really enjoy

NO CHANGE

today: I think you'll really enjoy

Correct answer:

NO CHANGE

Explanation:

Because these two clauses ("I’m so glad that you have all come to the Museum of Natural History today" and "I think you’ll really enjoy our exhibits") are independent and could function separately, they must either be joined by a comma and a conjunction OR by a punctuation mark that joins independent clauses with no conjunction. These punctuation marks include periods, semicolons, and dashes. In this case, the only answer that included a proper joining of two independent clauses was the original text, therefore no change was necessary.

Having finished his introduction, the permanent exhibition was the first thing that Dr. Mitchell showed to the class.

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 museum has three distinct types of exhibitions: permanent exhibitions, temporary exhibitions, and space shows.

The museum has three distinct types of exhibitions permanent exhibitions, temporary exhibitions, and space shows.

NO CHANGE

The museum has three distinct types of exhibitions; permanent exhibitions, temporary exhibitions, and space shows.

Correct answer:

The museum has three distinct types of exhibitions: permanent exhibitions, temporary exhibitions, and space shows.

Explanation:

"Permanent exhibitions, temporary exhibitions, and space shows" is a list, not an independent clause. It can therefore only be introduced by a colon. It cannot be introduced by a semicolon, as it does not function separately as an independent clause. The list must be introduced by a colon, which is why the answer that provides no punctuation ("three types of exhibition permanent exhibitions, temporary") is incorrect.

Example Question #27 : Punctuation Errors

Thomas placed his quill on the parchment, looking toward the mantel upon which, earlier that morning, he saw the painting of the old monastic saint, Benedict of Nursia. To his surprise, the mantel was empty, not having any items on it’s narrow flat surface. As the image had been a gift from his old schoolmaster; he was concerned at the absence of the item.

He asked himselfWhere could it have went?” Then, he gathered together his work and decided to ask one of his officemates about the cherished image. Leaving the room, he entered the foyer and turning to the secretary asked about the whereabouts of the others’.

The secretary looked at Thomas’ imposing figure and answered, “A group of the professors departed earlier for a University meeting; however, I cant recall exactly when they departed.” Although Thomas was not known for being passionate, the young secretary could see that he was agitated than usual.

The older man did not wish to worry his younger coworker. Smiling slightly, he said, “Don’t worry, Reginald. I seem to have misplaced my image of Benedict, though I know not how.” He continued by telling the younger man the chronology of events. Suddenly, the detailed recounting jogged the latters’ memory. He forgot an obvious detail that he only now remembered.

Looking at Thomas in embarrassment, Reginald, said, “Earlier this afternoon, I came in to your working area take the painting. Bonaventure had come to visit and asked to borrow it. You were so engrossed by you’re work that I did not want to disturb you. He will be stopping by to see you and I later today, so we can ask him to return it.”

What is the best form of the bolded selection, "from his old schoolmaster; he was concerned"?

Possible Answers:

from his old schoolmaster, he had been concerned

from his old schoolmaster, he was concerned

NO CHANGE

from his old schoolmaster; they were concerned

Correct answer:

from his old schoolmaster, he was concerned

Explanation:

The main problem with the sentence as written is its improper use of the semicolon to separate "schoolmaster" from "he." The clause, "As the image had been a gift from his old scholmaster," is subordinate to the main clause. It therefore requires a comma. The wrong answer that has a comma but then alters the verb to be "had been" is incorrect because of the odd use of tense. There is nothing in the sentence calling for the use of the past perfect in this manner.

Example Question #21 : Semicolon Errors

As a child the only thing I wanted to be was a race car driver. My mothers family all lived in central Indiana, and I went to the Indianapolis 500 every year growing up. Between the colors on the cars the speed of the race and the enthusiasm of the crowd, nothing in the world seemed more exciting to a child. I would lay awake at night thinking about getting behind the wheel of my own race car. My bedroom walls were adorned with posters of the all great racers from all over the world.

When I was a teenager, I had the opportunity to race go karts on small tracks against other kids my age. Very quickly I realized I am the terrible driver. Any bumping with another driver was too much for me to handle, and I could not take the turns quick enough to keep pace with the best drivers. None of this diminished my love of racing, however, because just being at the track was such a thrill. The noise, the speed, and rushing were all more exciting from the pits than from the grandstand. If I could never be in the driver’s seat, then I would place myself behind the scenes.

With this new focus, I began studying mechanical engineering and automotive design. I might not have been able to drive a race car; but now I could design a car, build a car, and engineer it to win a race. The drivers still get all the credit for the championships, but everyone knows they would never win without the people like myself.

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:

to drive a race car, but now

NO CHANGE

to drive a race car. But now

to drive a race car; and now

Correct answer:

to drive a race car, but now

Explanation:

A compound sentence, like the one that contains the underlined portion, joins two indpendent clauses together into one sentence to show their relationship. A compound sentence can only be properly joined by either a semicolon or a comma followed by a conjunction. As the underlined portion contains a conjunction, "but," the correct answer choice is "to drive a race car, but now."

Example Question #51 : Correcting Grammatical Errors

Adapted from The Sorrows of Young Werther by Johann Wolfgang von Goethe (1774; trans. Boylan 1854)

That the life of man is but a dream, many a man has surmised heretofore. I, too, am everywhere pursued by this feeling. When I consider the narrow limits within which our active and inquiring faculties are confined, I am silent. Likewise, when I see how all our energies are wasted in providing for mere necessities, which again has no further end than to prolong a wretched existence, I find myself to be silenced. Indeed, discovering that all our satisfaction concerning certain subjects of investigation ends in nothing better than a passive resignation, while we amuse ourselves painting our prison-walls with bright figures and brilliant landscapes—when I consider all this Wilhelm—I am silent. I examine my own being, and find there a world, but a world rather of imagination and dim desires, than of distinctness and living power. Then, everything swims before my senses, and I smile and dream while pursuing my way through the world.

All learned professors and doctors are agreed that children do not comprehend the cause of their desires; however, nobody is willing to acknowledge that the grown-ups should wander about this earth like children, without knowing whence they come or whither they go, influenced as little by fixed motives but, instead, guided like them by biscuits, sugar-plums, and the rod.

I know what you will say in reply. Indeed, I am ready to admit that they are happiest, who, like children, amuse themselves with their playthings, dress and undress their dolls.  They are happiest, who attentively watch the cupboard, where mamma has locked up her sweet things, and, when at last they get a delicious morsel, eat it greedily, and exclaim, "More!" These are certainly happy beings; but others also are objects of envy, who dignify their paltry employments (and sometimes even their passions) with pompous titles, representing them to mankind as gigantic achievements performed for their welfare and glory. However, the man who humbly acknowledges the vanity of all this, who observes with what pleasure the thriving citizen converts his little garden into a paradise, and how patiently even the poor man pursues his weary way under his burden, and how all wish equally to behold the light of the sun a little longer—yes, such a man is at peace, and creates his own world within himself. Indeed, he is also happy precisely because he is a man. And then, however limited his sphere, he still preserves in his bosom the sweet feeling of liberty and knows that he can quit his prison whenever he likes.

What is the best form of the bolded selection?

Possible Answers:

world, however, a world rather of imagination and dim desires, than of distinctness and living power

world; however, it is a world rather of imagination and dim desires, than of distinctness and living power

world; but, a world rather of imagination and dim desires, than of distinctness and living power

world, but a world rather of imagination and dim desires, than of distinctness and living power

Correct answer:

world; however, it is a world rather of imagination and dim desires, than of distinctness and living power

Explanation:

The sense of the conjunction "but" in this sentence is clearly meant to draw out the contrast between what one might expect from this "world" (as a "world") and what it really is: an imaginary world, not one of distinctness and power. Since the style itself obscures the meaning, it would be best to set this off with a semi-colon and start a new independent clause, clearly stating the contrast by using "however."
