Example Question #381 : Act English

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

James chose a large, rusty car, Philip chose a brand new car, and I chose the cheapest, ugliest car on the lot.

Possible Answers:

James chose a large rusty car Philip chose a brand new car and I chose the cheapest ugliest car on the lot.

James chose a large, rusty car, Philip chose a brand new car; and I chose the cheapest, ugliest car on the lot.

NO CHANGE

James chose a large rusty car, Philip chose a brand new car, and I chose the cheapest ugliest car on the lot.

James chose a large, rusty car; Philip chose a brand new car; and I chose the cheapest, ugliest car on the lot.

Correct answer:

James chose a large, rusty car; Philip chose a brand new car; and I chose the cheapest, ugliest car on the lot.

Explanation:

Because the first and third clauses in this sentence contain commas themselves, semicolons are needed to separate the clauses in order to avoid confusion.  Also, because the phrases "large, rusty car" and "cheapest, ugliest car" can also be rendered as "large and rusty car" and "cheapest and ugliest car", the commas separating the adjectives are necessary.

Example Question #1 : Semicolon Errors

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

Sawyer attended that high school his first solo violin performance took place in the auditorium during his sophomore year.

Possible Answers:

NO CHANGE

that high school? His first

that high school; his first

that high school, but his first

that high school, his first

Correct answer:

that high school; his first

Explanation:

Unchanged, the presented sentence is a run-on. The option "that high school, his first" does not fix it completely as it is a comma splice. The option "that high school, but his first" does join the two independent clauses, but it is incorrect as it indicates the two clauses contradict each other. The correct answer, "that high school; his first" correctly joins the two related independent clauses with a semicolon.

Example Question #11 : Semicolon Errors

Adapted from The Apology by Plato (trans. Jowett)

This inquisition has led to my having many enemies of the worst and most dangerous kind and has given occasion also to many false statements against me. And I am called wise, for my hearers always imagine that I myself possess the wisdom which I find lacking in others. However, O men of Athens, the truth is that god only is wise. By his answer he intends to show that the wisdom of men is worth little or nothing. He is not speaking of Socrates, he is only using my name by way of illustration. It is as though he said, “He, O men, is the wisest, who, like Socrates, knows that his wisdom is in truth worth nothing.” And so, I go about the world, obedient to the god, searching and making enquiry into the wisdom of any one, whether citizen or stranger, who appears to be wise. If he is not wise, then I show him that he is not wise. My occupation quite absorbs me, and I have no time to give either to any public matter of interest or to any concern of my own. Indeed I am in utter poverty by reason of my devotion to the god.

There is another thing. Young men of the richer classes, who have not much to do, come about me of their own accord. They like to hear my examinations of others and often imitate me, and then proceed to examine others. They quickly discover that there is plenty of people, who think that they know something but really know little or nothing. Then, those who are examined by them instead of being angry with themselves become angry with me. 

“This confounded Socrates,” they say, “this villainous misleader of youth!” And then, if somebody asks them, “What evil does he practice or teach?” they do not know and cannot tell. However, in order that they may not appear to be at a loss, they repeat the ready-made charges which are used against all philosophers: the teaching things up in the clouds and under the earth, having no gods, and making wrong things appear to be right. 

They do not like to confess that their pretence of knowledge has been detected (which is the truth). And as they are numerous and ambitious and energetic, they have filled your ears with they’re loud and inveterate calumnies.

And this, O men of Athens, is the truth and the whole truth. I have concealed nothing; I have dissembled nothing. And yet, I know that my plainness of speech makes them hate me. Still, what is their hatred but a proof that I am speaking the truth? From this have arisen the crowds’ prejudice against me. This is the reason of it, as you will find out either in this or in any future enquiry.

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

Possible Answers:

He is not speaking of Socrates, but he is only using my name by way of illustration.

He is not speaking of Socrates—he is only using my name by way of illustration.

He is not speaking of Socrates: he is only using my name by way of illustration.

NO CHANGE

He is not speaking of Socrates; he is only using my name by way of illustration.

Correct answer:

He is not speaking of Socrates; he is only using my name by way of illustration.

Explanation:

As written, the sentence contains a comma splice, as it separates two independent clauses with a comma, which is grammatically incorrect. Among the options provided, the best option is the one that uses a semicolon to separate the two clauses. The colon is completely improper. The hyphen could be justified as a rhetorical device, but the more certain answer of the two is the one that uses the semicolon.

Example Question #384 : Act English

Adapted from Looking Backward from 2000 to 1887  by Edward Bellamy (1889)

"Here we are at the store of our ward," said Edith, as we turned in at the great portal of one of the magnificent public buildings I had observed in my morning walk. There was nothing in the exterior aspect (1) of the edifice to suggest a store to a representative of the nineteenth century. There was no display of goods in the great windows, or any device to advertise wares, or attract custom (2). Nor was there any sort of sign or legend on the front of the building to indicate the character of the business carried on there; but instead, above the portal, standing out from the front of the building, a majestic life-size group of statuary (3), the central figure of which was a female ideal of Plenty, with her cornucopia. Judging from the composition of the throng (4) passing in and out, about the same proportion of the sexes among shoppers obtained (5) as in the nineteenth century. As we entered, Edith said that there was one of these great distributing establishments in each ward of the city, so that no residence was more than five or ten minutes (6) walk from one of them. It was the first interior of a twentieth-century public building that I had ever beheld, and the spectacle naturally impressed me deeply. I was in a vast hall full of light, received not alone from the windows on all sides, but from the dome, the point of which was a hundred feet above. Beneath it, in the centre of the hall, a magnificent fountain played, cooling the atmosphere to a delicious freshness with its spray. The walls and ceiling were frescoed in mellow tints, calculated to soften without absorbing the light which flooded the interior. Around the fountain was a space occupied with chairs and sofas, on which many persons were seated conversing. Legends (7) on the walls all about the hall indicated to what classes of commodities the counters below were devoted. Edith directed her steps towards one of these, where samples of muslin of a bewildering variety were displayed, and proceeded to inspect them.

"Where is the clerk?" I asked, for there was no one behind the counter, and no one seemed coming to attend (8) to the customer.

"I have no need of the clerk yet," said Edith (9) "I have not made my selection."

"It was the principal business of clerks to help people to make their selections in my day," I replied.

"What! To tell people what they wanted?"

"Yes (10) and oftener to induce them to buy what they didn't want."

"But did not (11) ladies find that very impertinent?" Edith asked, wonderingly (12). "What concern could it possibly be to the clerks whether people bought or not?"

Choose from the following four options the answer that best corrects the underlined mistake preceding the number (9). If there is no mistake or the original text is the best option, choose "NO CHANGE."

Possible Answers:

NO CHANGE

Edith,

Edith:

Edith;

Correct answer:

Edith;

Explanation:

Edith is making two separate statements rather than uttering a single sentence, so the semicolon would be the most appropriate choice here.

Example Question #11 : Punctuation Errors

From an adaptation of a Letter from Thomas Jefferson to John Adams, On the Occasion of the Death of the Latter's Wife Abigail (1818)

The public papers my dear friend, have announced the fatal event of which your letter of October the 20th had given me ominous foreboding. Tried myself in the school of affliction, by the loss of every form of connection which can rive the human heart, I know well and feel what you have lost, what you have suffered, are suffering, and have yet to endure. The same trials have taught me that for ills so immeasurable, time and silence are the only medicine. I will not, therefore, by useless condolences, open afresh the sluices of your grief, nor, although mingling sincerely my tears with yours, will I say a word more where words are vain, but that it is of some comfort to us both, that the term is not very distant at which we are to deposit our sorrows and suffering bodies in the same soil and to ascend in essence to an ecstatic meeting with the friends we have loved and lost, and whom we shall still love and never lose again. God bless you and support you under your heavy affliction.

Which of the following is the best form of, "Open afresh the sluices of your grief, nor, although mingling sincerely my tears with yours"?

Possible Answers:

open afresh the sluices of your grief; nor, although mingling sincerely my tears with yours

open afresh the sluices of your grief nor although mingling sincerely my tears with yours

open afresh the sluices of your grief, nor, although mingling sincerely my tears with yours

open afresh the sluices of your grief: nor, although mingling sincerely my tears with yours

Correct answer:

open afresh the sluices of your grief; nor, although mingling sincerely my tears with yours

Explanation:

Simplifying the long prose will help you to see the two independent clauses involved here:  (1) "I will not . . . open . . . the sluices of your grief"; (2) "nor . . . will I say a word more where words are vain."

Therefore, it will be best to separate these two clauses either with a semicolon or with a period. Note that this is a somewhat odd use of "nor," for we use it today as a correlative conjunction with "neither." Here, the sense of "nor" is something like saying, "Likewise . . . I will not . . ." Another way that the sentence could be completely rewritten would be something like: "I will neither . . . open afresh . . . nor will I . . ."  However, this is not the question presented here.

Example Question #11 : 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 is the best form of the boldfaced and underlined section?

Possible Answers:

country: because,

country; because,

country because

country; for,

Correct answer:

country because

Explanation:

Admittedly, this sentence is a bit wordy, so it is difficult to come up with a "textbook" form for the answer. Look for the least bad answer among those offered. The independent clause following the "for" indicates the reason for the modifications proposed earlier in the sentence. The sense of the "for" is because or since. The best option among those provided is the one that makes this explicit but does so without using a semicolon. This use of a semicolon creates a fragment for the second complete clause (i.e. the whole portion including the "because" or "for" after the semicolon).

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.

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.
