Example Question #755 : Punctuation Errors

Fashion, that ever-changing entity has thrown us some curveballs in the last year. No one expected that gym pants would become acceptable workwear, but shockingly, that’s exactly what has happened! First seen on the runway these casual, slouchy pants bridge the gap between exercise attire and business casual. They have comfortable, elastic waists but feature crisp lines and smart patterns.

Even though top executives have been seen sporting this edgy look, that doesn’t necessarily mean that you can pull it off too! Think about your office dress code and how relaxed it is. For instance, do you see other people in your office wearing less traditional clothing, and do people push the boundaries without getting in trouble. If every person in your office is wearing a button-down shirt, suits, and a tie, this fun fashion may be best left to the weekend.

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

Possible Answers:

that’s exactly what has happened.

NO CHANGE

that's exactly what has happened,

that's exactly what has happened!!

that's exactly what has happened?

Correct answer:

NO CHANGE

Explanation:

This question asks you about the grammatically correct use of an exclamation point. An exclamation point should be used to add emphasis or express a strong thought. In this sentence, an exclamation point is correct punctuation to add emphasis because the word "shockingly" indicates that this is meant to be a strong statement. Although a period is grammatically correct here, it is not the strongest stylistic choice. A question mark is incorrect since this is not a question. The use of a comma would create a comma splice. It is not grammatically correct to use two exclamation points to add additional emphasis.

Possible Answers:

NONE OF THESE

without getting in trouble?

without getting in trouble!

without getting in trouble

NO CHANGE

Correct answer:

without getting in trouble?

Explanation:

This question asks you about the appropriate punctuation to use at the end of a sentence. Since this sentence is a question, it should end with a question mark. A period or exclamation point should not be used to end a question. A lack of any punctuation creates a run-on sentence.

Example Question #1121 : Act English

“Justice and Parents”

We tend to think of justice as a matter of strict equality.  For example if someone wants to buy an item, they are understandably expected to pay an amount that is roughly equal to its value.  Likewise, when a law declares that the penalty for speeding is $150, it is considered just that one who breaks this law pays the fine.  However, justice can also pertain to matters that are beyond mere equality.

An obvious example of this is the case of the relationship between children and their parents.  Unlike the cases discussed earlier, children will have had little opportunity to repay they’re parents for all that they have done for them.  Technically speaking, strict “equality” would require the child to give birth to the parents.  This is an absurd thing to suggest.  Similarly absurd is the suggestion that children should directly repay the rearing offered by parents.  Once again, strict equality cannot occur in the child-parent relationship.

However, there is a kind of justice between children and his or her parents.  For example, when a parent ages and is in need of assistance, if the adult child can provide assistance but refuses to do so.  This is a kind of injustice to the parents.  On a more positive note.  For example, an adult child might send his parents on a cruise in memory of their anniversary.  Such an action would be a kind of “justice” done to the parents—at least in that it recognizes the immense debt that is owed by the child to the parents in question.

In these (and many other cases), justice is less about equality than it is about paying what one can pay.  That is, in such cases, both justice or injustice is determined by worthiness that surpasses mere equality.  This kind of justice could be called justice above justice.  That is, it is a kind of justice that surpasses the “normal” justice of equality.  Such acts of justice ensure that society does not become reduced to the cold calculation of equality but, instead, has the warmth of true affection and loving gratitude.

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

Possible Answers:

This was an absurd thing to suggest!

This had been an absurd thing to suggest!

This was an absurd thing to suggest.

NO CHANGE

This is an absurd thing to suggest!

Correct answer:

This is an absurd thing to suggest!

Explanation:

As written, the sentence does not require any change in tense. It merely needs to have an exclamation point added. The sentence breaks the flow slightly and sounds like an exclamation that someone might make in surprise. For this reason, it makes sense to end the sentence with an exclamation point in this manner, so as to accentuate the surprise that the words themselves express as well.

Example Question #1 : Errors Involving Hyphens, Dashes, And Parentheses

When I retired I took up sprinting.  I ran for my university track team a D3 team so don’t get too excited—and performed as a top athlete in our conference.  I fell in love with running so much that I even signed up to run cross country in the fall.  Endurance is not my thing and that is part of why I am lazy.  I played soccer one season because the team needed an extra body.  I was an awful terrible soccer player but it was so much fun!  

What would make the underlined portion grammatically correct?

Possible Answers:

track team—a D3 team so don’t get too excited—and

track team which was a D3 team so don’t get too excited—and

track team, a D3 team so don’t get too excited—and

track team a D3 team so don’t get too excited and

NO CHANGE

Correct answer:

track team—a D3 team so don’t get too excited—and

Explanation:

Dashes are used to set apart extra information that is not vital to the sentence, meaning the sentence has a subject and a verb of its own without the portion dashed off; however, if the extra information is located in the middle of the sentence, it must be surrounded by a dash on both sides.

Example Question #2 : Errors Involving Hyphens, Dashes, And Parentheses

What would make the underlined portion grammatically correct?

To begin I should explain how it is that I am a sports-lover but lazy.  I have tried as many sports as have been possible in my life and I have enjoyed all of them.  I had competed in national gymnastics which is probably the most holistically challenging for ten years.  This sport took precedence in all of middle and high school for me.  

Possible Answers:

competed in national gymnastics—which is probably the most holistically challenging of all the sports I did—for ten

competed in national gymnastics; which is probably the most holistically challenging of all the sports I did for ten

NO CHANGE

competed in national gymnastics. Which is probably the most holistically challenging of all the sports I did—for ten

competed in national gymnastics, which is probably the most holistically challenging of all the sports I did—for ten

Correct answer:

competed in national gymnastics—which is probably the most holistically challenging of all the sports I did—for ten

Explanation:

Extra information must be separated from the sentence by commas, dashes, or parenthesis. The same punctuation must be used to open the extra information as is used to close it.  

Example Question #3 : Errors Involving Hyphens, Dashes, And Parentheses

Adapted from Sozein ta Phainomena: An Essay Concerning Physical Theory from Plato to Galileo by Pierre Duhem (translated by Matthew Minerd)

What are physical theories’ value? What relation does it have with metaphysical explication? These are questions that are greatly stirred and raised in our days. However, as with other questions, they are in no manner completely new. It is a question that has been posed in all ages. As long as there has been a science of nature, they have been posed. Granted, the form that they assume changes somewhat from one age to another, for they borrow their various appearance from the scientific vocabularies of their times. Nevertheless, one need only dismiss this outer vestment in order to recognize that they remain essentially identical to each other.

The science of nature offers us up until the 17th century at least, very few parties that managed to create theories expressed in a mathematical language. . . . If we leave aside several exceptions, an historical investigation places before our eyes strong evidence of a type science that would indeed be a prediction of modern mathematical physics. This science is astronomy. That is, where we would say, “Physical theory,” the Greek, Muslim, Medieval, and early Renaissance sages would say, “Astronomy.” However, for these earlier thinkers, the other parts of the study of nature did not attain a similar degree of perfection. That is, they did not express the laws of experience in a mathematical manner similar to that found in astronomy. In addition, during this time, the study of the material realities generally were not separated from what we would call today, “metaphysics.”

Thus, you can see why the question that concerns us takes two related, though different forms. Today, we ask, “What are the relations between metaphysics and physical theory?” However, in past days; indeed, for nearly two thousand years; it was formulated instead as, “What are the relations between physics and astronomy?”

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:

However in past days indeed for nearly two thousand years

However, in past days—indeed, for nearly two thousand years—

However, in past days, indeed, for nearly two thousand years;

However, in past days; indeed, for nearly two thousand years;

However, in past days, indeed, for nearly two thousand years,

Correct answer:

However, in past days—indeed, for nearly two thousand years—

Explanation:

The phrase, "indeed, for nearly two thousand years" functions almost as a pure aside by the author. Since it significantly alters the flow of ideas, it is best to set it off by something more than mere commas. (This is particularly the case here, where there are already many commas involved.) You could do this either with long dashes or with parentheses.

Example Question #4 : Errors Involving Hyphens, Dashes, And Parentheses

Adapted from The Picture of Dorian Gray by Oscar Wilde

As they entered, they saw Dorian Gray who was seated at the piano his back to them, turning over the pages of a volume of Schumann's "Forest Scenes." "You must lend me these, Basil," he cried. "I want to learn them. They are perfectly charming." "That entirely depends on how you sit to-day, Dorian."

"Oh, I am tired of sitting, and I don't want a life-sized portrait of myself," answered the lad, swinging round on the music-stool in a willful, petulant manner. When he caught sight of Lord Henry, a faint blush colored his cheeks for a moment, and he started up. "I beg your pardon, Basil. I did’nt know you had any one with you."

"This is Lord Henry Wotton, Dorian, an old Oxford friend of mine. I have just been telling him what a capital sitter you were, and now you have spoiled everything."

"You have not spoiled my pleasure in meeting you, Mr. Gray," said Lord Henry, stepping forward and extended his hand. "My aunt has often spoken to me about you. You are one of her favorites, and, I am afraid, one of her victims also."

"I am in Lady Agatha's black books at present," answered Dorian with a funny look of penitence. "I promised to go to a club in Whitechapel with her last Tuesday, and I really forgot all about it. We were to have played a duet together: three duets, I believe. I don't know what she will say to me. I am far too frightened to call."

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:

played a duet together three duets, I believe

played a duet together—three duets. I believe

played a duet together; three duets, I believe

NO CHANGE

played a duet together—three duets, I believe

Correct answer:

played a duet together—three duets, I believe

Explanation:

Certainly, there needs to be some separation between "together" and "three." However, it is not correct to use a colon here. Colons are used before the enumeration of lists or directly stating some fact (e.g. "There is only one option: eat the peas!"). Among the options provided, only the hyphen provides an acceptable separation.

Example Question #5 : Errors Involving Hyphens, Dashes, And Parentheses

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.

Consider the boldfaced and underlined selection in the first paragraph. Given that the commas are correctly placed, which of the following would be most closely equivalent?

Possible Answers:

species, or between the individuals of the same species; for

species—or between the individuals of the same species—for

species; or between the individuals of the same species; for

species; or between the individuals of the same species, for

Correct answer:

species—or between the individuals of the same species—for

Explanation:

Although the original use of commas is a bit awkward for contemporary English grammar, if we take them as being correctly placed, we can see that the author is trying to signal an "aside." That is, he is making an additional concession to his reader, as though saying, "between a few species—okay, or even between individuals—for." If we wish to retain the sense of this being an "aside" or extra concession, the best option among those provided is the one that uses dashes.

Example Question #6 : Errors Involving Hyphens, Dashes, And Parentheses

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.

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

landscapes—when I consider all this, Wilhelm—I am silent

landscapes—when I consider all this, Wilhelm, I am silent

landscapes, when I consider all this, Wilhelm, I am silent

landscapes—when I consider all this Wilhelm, I am silent

Correct answer:

landscapes—when I consider all this, Wilhelm, I am silent

Explanation:

This is a long sentence, so let us break it down:

"Indeed, discovering . . . "

Discovering what? "that all our satisfaction concerning certain subjects of investigation ends in nothing better than a passive resignation"

To this is added the subordinate clause: "while we amuse ourselves painting our prison-walls with bright figures and brilliant landscapes"

Now, after this, the author comes to the main clause: "when I consider all this, Wilhelm, I am silent."

This could also be written: "I am silent, Wilhelm, when I consider all this."

Therefore, the best form of this phrase will set off the introductory portion with a long dash and set off "Wilhelm" with commas (because of direct address to a person).

Example Question #5 : Errors Involving Hyphens, Dashes, And Parentheses

How should doctors plan treatments for patients? In Western medicine, many believe that illnesses are just problems that can be fixed with the right combination of drugs: but maybe to really treat illnesses, we also have to examine the ways that illnesses take on meanings in different cultural, social, and historical contexts.

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:

drugs: but maybe, to really

drugs – but maybe to really

NO CHANGE

drugs but maybe to really

drugs but maybe, to really

Correct answer:

drugs – but maybe to really

Explanation:

Here, a dash is the best way to connect the two related phrases. Since the two phrases before and after the colon can be independent sentences by themselves, a semicolon could also work. However, that's not one of the choices. A colon would not work, since it is only used to introduce a list or details that illustrate what is said before the colon. A pause is needed after “drugs”, but is not needed after “maybe”, which is why two of the other answers would not work.
