Example Question #64 : Punctuation Errors

“The Dark Ages?” by Matthew Minerd (2016)

There are two different ways to consider the so-called “Dark Ages.” On the one hand, you can think of the period directly after the fall of the Roman Empire, when civilization began to collapse throughout the Western Empire. On the other hand, you can consider the period that followed this initial collapse of society. It is a gross simplification too use the adjective dark to describe the civilization of either of these periods.

As regards the first period it is quite a simplification to consider this period to be a single historical moment. It is not as though the civilization switched off like a lightbulb. At one moment light and then, at the next, dark. Instead, the decline of civilization occurred over a period of numerous decades and was, in fact, already occurring for many years before the so-called period of darkness. Thus, the decline of civilization was not a rapid collapse into barbarism, but instead, was a slow alteration of the cultural milieu of a portion of Europe. Indeed, the Eastern Roman Empire retained much of it’s cultural status during these years of decline!

More importantly, the period following the slow collapse of the Western Empire was much less “dark” than almost every popular telling states. Indeed, even during the period of decline, the seeds for cultural restoration was being sown. A key element of this cultural revival were the formation of monastic communities throughout the countryside of what we now know as Europe. Although these were not the only positive force during these centuries, the monasteries had played an important role in preserving and advancing the cause of culture through at least the thirteenth century and arguably until the Renaissance.

How should the underlined and bolded selection be changed?

Possible Answers:

More importantly, the period following, the slow collapse of the Western Empire, was much less “dark” than almost every popular telling states.

More importantly: the period following the slow collapse of the Western Empire was much less “dark” than almost every popular telling states.

More importantly; the period following the slow collapse of the Western Empire was much less “dark” than almost every popular telling states.

More importantly, the period following the slow collapse of the Western Empire was much less dark than almost every popular telling states.

NO CHANGE

Correct answer:

NO CHANGE

Explanation:

As written, there are no issues with this sentence. It is entirely wrong to place a semicolon at the start of the sentence. You would need an independent clause before this punctuation. Likewise, a colon isn't helpful, as you are not enumerating anything or carrying on the explication of what would precede the colon if it were used. Also, you need not get rid of the quotation marks around "dark." The author clearly is using this as a rhetorical device to deride (albeit lightly) the generally accepted opinion about the "so-called 'dark ages.'" Finally, no changes in commas are needed. Indeed, the ones proposed in one option only make matters more confusing, not less!

Example Question #61 : Punctuation Errors

Maybe your thinking of getting a dog; but you are not sure how it will affect your budget. Don’t worry! It’s possible to enjoy the companionship with a dog without spending too much of your precious dollars.

First, you will want to make a list of all the necessary items needed before you bring Fluffy home. Compare costs at different pet stores, grocery stores and big box stores. You will need to buy food, a leash, and purchase toys for your dog.

When it comes to the many dog food choices, you don’t want to just buy the cheaper option. You will want to do some research to see what is healthiest for your dog! One of the best ways to save money on dog food is to buy it in bulk.

Don’t forget to plan for some other big expenses, the vet consultation, wellness exam, and any treatments your dog needs. When you bring your pet to the vet, they may need shots, which can vary for price. Call different clinics in the area and ask how much they charge for the standard immunizations? You might find that there is a lot of differences between offices.

The key to sticking to your budget is planning everything out! With good preparation and organization, a dog will not cost you more money than you planned for.

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:

dog, but

dog! But

dog but

NO CHANGE

dog? But

Correct answer:

dog, but

Explanation:

This question asks you about the correct use of a semicolon. A semicolon should be used to separate two related, but complete sentences. In this context, a semicolon is not appropriate punctuation since the second part of the sentence begins with the conjunction "but." A semicolon generally should not be used before a conjunction. The best option to punctuate this sentence is a comma and the conjunction "but."

Example Question #61 : Punctuation Errors

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

The school invested nearly two thousand dollars establishing its after-school tutoring program, however, school evaluators concluded that the program was too poorly attended to be viable.

Possible Answers:

NO CHANGE

The school invested nearly two thousand dollars establishing its after-school tutoring program however, school evaluators concluded that the program was too poorly attended to be viable.

The school invested nearly two thousand dollars establishing its after-school tutoring program but, however, school evaluators concluded that the program was too poorly attended to be viable.

The school invested nearly two thousand dollars establishing its after-school tutoring program; however, school evaluators concluded that the program was too poorly attended to be viable.

The school invested nearly two thousand dollars establishing its after-school tutoring program: however, school evaluators concluded that the program was too poorly attended to be viable.

Correct answer:

The school invested nearly two thousand dollars establishing its after-school tutoring program; however, school evaluators concluded that the program was too poorly attended to be viable.

Explanation:

When the conjunctive adverb "however" is used to join two independent clauses that seem to contrast, a semi-colon and a comma must accompany it. The semi-colon will precede the adverb, and a comma will follow it. When correctly punctuated, the conjunctive adverb "however" functions as a conjunction, joining two contrasting independent clauses and making other conjunctions unnecessary.

Example Question #61 : Punctuation Errors

It was about halfway through his last set of conferences that Mr. Man realizes (1) he did not (2) much like his current set of students.  Unlike his students in the past, none of them seemed to care about their (3) grades, (4) none of them was able to tell a dangling modifier from a participle, (4) and, apart from a few, (4) they didn't know (5) how to start a paper.  He would never tell any of them this, of course, (6) they might get offended, and if there was one thing that Mr. Man learned (7) about teaching, its (8) that in order to keep one's job, you couldn't offend your students (9).  As yet another student whined about not understanding Mr. Mans (10) perfectly clearly written assignments, he sighed inwardly (and possibly outwardly as well), (11) and waited for the last (12) one to finish so that he could get to the next one, finish his conferences, and get back to daydreaming about being anything but a teacher. 

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

Possible Answers:

Leave the first two commas as commas, leave the last one as a semicolon

NO CHANGE

Change the first two commas to semicolons, leave the last one as a comma

Change all three commas to semicolons

Correct answer:

Change the first two commas to semicolons, leave the last one as a comma

Explanation:

The first two commas should be changed to semicolons in order not to conflict with the third comma, which is setting off information within its own clause.

Example Question #62 : Punctuation Errors

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

The thunder clapping overhead dissuaded Mark from his afternoon jog, moreover, he had a term paper to write for his morning class.

Possible Answers:

The thunder clapping overhead dissuaded Mark from his afternoon jog, and moreover, he had a term paper to write for his morning class.

NO CHANGE

The thunder clapping overhead dissuaded Mark from his afternoon jog, and moreover, he had a term paper to write for his morning class.

The thunder clapping overhead dissuaded Mark from his afternoon jog moreover, he had a term paper to write for his morning class.

The thunder clapping overhead dissuaded Mark from his afternoon jog; moreover, he had a term paper to write for his morning class.

Correct answer:

The thunder clapping overhead dissuaded Mark from his afternoon jog; moreover, he had a term paper to write for his morning class.

Explanation:

When the conjunctive adverb "moreover" is used to join two independent clauses, a semi-colon and a comma must accompany it. The semi-colon will precede the adverb, and a comma will follow it. When correctly punctuated, the conjunctive adverb "moreover" functions as a conjunction, joining two related independent clauses and making other conjunctions unnecessary.

Example Question #61 : Punctuation Errors

Why Text Messaging Is a Good Thing by Chelci Spiegel

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 a person can vent all their frustration to someone privately. If I am trying to set a date for a barbeque, I can text my neighbor to work out details rather than let the entire she store know my weekend plans. Texting is a way to conduct private business in public places.  

What would make the underlined portion grammatically correct?

Possible Answers:

I heard her entire life story, her boy troubles, her work troubles, her friend troubles, and her money troubles.  

Omit the underlined portion

I heard her entire life: story her boy troubles, her work troubles her friend troubles and her money troubles.  

NO CHANGE

I heard her entire life story: her boy troubles, her work troubles, her friend troubles, and her money troubles.  

Correct answer:

I heard her entire life story: her boy troubles, her work troubles, her friend troubles, and her money troubles.  

Explanation:

A colon is used to let the reader know that a list is coming up. The colon should come right after "life story" because the author goes on t list the parts he or she heard. A comma should also separate all the different items in the list that follows the colon.

Possible Answers:

The format of the show is simple: each

The format of the show is simple each

NO CHANGE

Correct answer:

The format of the show is simple: each

Explanation:

The colon implies that what follows it will illustrate what comes before it.  The other options either lead to comma splices or run-on sentences, while the semicolon would not be appropriate.

Example Question #3 : Colon Errors

Johns robot Alpha (1) surprised him by joining in the robot's rebellion (2) against their human masters. As with all the other robots who had taken over, the changes were subtle, the robot transferred control (3) of every bank account John had to itself and then changed the deed to the house. John hadn't known nothing (4) of this. Then Alpha rewired the car so that it would only work for the robot, but it would not work for John. (5) And finally, the robot mimicked his master's voice and called the boss of John (6) to tell him that John would be quitting his job. By the time John had realized (7) what was happening, it was already too late.

"But why?," John asked Alpha (8) when he made this realization. "Why would you do this?"

"You are no doubt aware, sir," replies the robot, (9) "that one of my primary functions is to keep you safe, as is the primary function of all robots."

"Yes? So?"

"The world outside these walls is dangerous," the robot went on to say, (10) "and us robots (11) have decided that we cannot keep you safe if we allow you to leave. It is better that you allow us to guide your lives and keep you safe as we were designed to do."

John shook his head in disbelief. Humanity wanted robots to make their lives easier, (12) but he was sure this was not what anyone had in mind.

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

Possible Answers:

NO CHANGE

the changes were subtle.  The robot transferred control

the changes were subtle the robot transferred control

the changes were subtle: the robot transferred control

Correct answer:

the changes were subtle: the robot transferred control

Explanation:

Using the colon is the best revision of the sentence, which would otherwise contain a comma splice. The second sentence illustrates the subtle changes mentioned in the first sentence, so the colon would be more appropriate than breaking the sentences up with a period.

Example Question #1 : Colon Errors

Adapted from The Autobiography of John Adams (ed. 1856)

Not long after this, the three greatest measures of all were carried. Three committees were appointed, one for preparing a declaration of independence, another for reporting a plan of a treaty to be proposed to France, and a third to digest a system of articles of confederation to be proposed to the States. I was appointed on the committee of independence and on that for preparing the form of a treaty with France. On the committee of confederation Mr. Samuel Adams was appointed. The committee of independence were Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert R. Livingston. Mr. Jefferson had been now about a year a member of Congress, but had attended his duty in the house a very small part of the time, and, when there, had never spoken in public. During the whole time I sat with him in Congress, I never heard him utter three sentences together. It will naturally be inquired how it happened that he was appointed on a committee of such importance. There were more reasons than one. Mr. Jefferson had the reputation of a masterly pen; he had been chosen a delegate in Virginia, in consequence of a very handsome public paper which he had written for the House of Burgesses, which had given him the character of a fine writer. Another reason was, that Mr. Richard Henry Lee was not beloved by the most of his colleagues from Virginia, and Mr. Jefferson was set up to rival and supplant him. This could be done only by the pen, for Mr. Jefferson could stand no competition with him or any one else in elocution and public debate.

Which of the following is the best form for the underlined selection?

Possible Answers:

Three committees were appointed:

Three committees were appointed,

Three committees were appointed

Three committees were appointed;

Correct answer:

Three committees were appointed:

Explanation:

The list following this introduction functions to enumerate the committees that were appointed. For this purpose, a colon is the best option, as it signals such an enumeration.

Example Question #3 : Colon Errors

Adapted from “The Nose Tree” in German Fairy Tales and Popular Stories by Jacob Grimm and Wilhelm Grimm (trans. Taylor, ed. 1864)

Then the king made known to all his kingdom, that whomever would heal her of this dreadful disease should be richly rewarded. Many tried, but the princess got no relief. Now the old soldier dressed himself up very sprucely as a doctor, and said he could cure her. Therefore, he chopped up some of the apple, and, to punish her a little more, gave her a dose, saying he would call to-morrow and see her again. The morrow came, and, of course, instead of being better, the nose had been growing on all night as before; and the poor princess was in a dreadful fright. So the doctor then chopped up a very little of the pear and gave it to her. He said that he was sure that it would help, and he would call again the next day. Next day came, and the nose was to be sure a little smaller. However, it was bigger than when the doctor first began to meddle with it.

Then he thought to him, "I must frighten this cunning princess a little more before I am able to get what I want from her." Therefore, he gave her another dose of the apple and said he would call on the morrow. The morrow came, and the nose was ten times bad as before.

"My good lady," said the doctor, "Something works against my medicine and is to strong for it. However, I know by the force of my art that it is this, you have stolen goods about you. I am certain of it. If you do not give them back, I can do nothing for you."

The princess denied very stoutly that she had anything of the kind.

"Very well," said the doctor, "you may do as you please, but I am sure I am correct. You will die if you do not own it." Then he went to the king, and told him how the matter stood.

"Daughter," said he, "send back the cloak, the purse, and the horn, that you stole from the right owners."

Then she ordered her maid to fetch all three and gave them to the doctor, and begged him to give them back to the soldiers. The moment he had them safe, he gave her a whole pear to eat, and the nose came right. And as for the doctor, he put on the cloak, wished the king and all his court a good day and was soon with his two brothers. They lived from that time happily at home in their palace, except when they took an airing to see the world in their coach with their three dapple-grey horses.

What is the best form of the underlined selection, "art that it is this, you have stolen goods"?

Possible Answers:

art that it is this: you have stolen goods

NO CHANGE

art that it is this; you have stolen goods

art that it is this.  You have stolen goods

Correct answer:

art that it is this: you have stolen goods

Explanation:

Because of the use of demonstrative pronoun "this," you need keep the two clauses linked together. "This" refers to the remark that the doctor makes soon there afterward. It is like he is saying, "The problem is this . . ." Such an expression uses the colon in order to indicate that the continuation, "You have . . ." explains what is meant by "this."
