Example Question #661 : 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."

There is no reason to believe that todays’ children will be significantly influenced by current events.

Possible Answers:

today children

today children's

today's children

NO CHANGE

todays children

Correct answer:

today's children

Explanation:

This question is testing your understanding of possessive apostrophes. Because you could substitute the underlined phrase with "children of today," the correct answer choice is "today's children."

When the apostrophe is outside of the s, this implies more than one subject. For example, "the girl's cat" compared to "the girls' cat" would refer to the cat of a single girl compared to the cat of a more than one girl. Because there is only one "today," the apostrophe should be inside the s as "today's."

Example Question #662 : 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."

Its perfectly fair to consider extracurricular activities as important factors in admissions.

Possible Answers:

It'll

It'

It's

It

Its'

Correct answer:

It's

Explanation:

"Its" is used as a possessive. In other words, when one thing belongs to another (ex. its book = the book belongs to it). "It's" is a contraction for "it is" (ex. it's fun = it is fun). In this case, the sentence is trying to say "It is perfectly fair..." Therefore, the correct answer is "it's."

Example Question #112 : Apostrophe 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:

you

are you

you're

NO CHANGE

you were

Correct answer:

you're

Explanation:

This question asks about the correct use of an apostrophe. In this sentence, the context demands the use of the contraction for "you are," so "you're" is the best answer. The use of "your" or "you" leaves the clause without a main verb. This passage takes place in the present tense, so it is not correct to use the past tense, "you were." Since it is not a question, there is no need to use the interrogative form, "are you."

Example Question #111 : Apostrophe 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 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:

your offices dress code

your office's dress code

your offices' dress code

the dress code of your office's

NO CHANGE

Correct answer:

your office's dress code

Explanation:

This question asks about the correct use of an apostrophe to indicate possession. In this sentence, the "dress code" belongs to the "office," so a possessive form should be used. The correct singular possessive form is "office's." Since the author is referring to each reader's individual office, it is not correct to use a plural form of "office."

Example Question #114 : Apostrophe Errors

“On the Nature of Belief”

Belief and faith often are critiqued in a scientific culture.  It can seem that mere belief is a replacement for science made available to soothe the ignorant masses.  There is some truth to such accusations, and many people do use belief as a screen to cover their own ignorance about the truths of reality.  Everyone should be aware, however, that almost every single human being have these kinds of “blind spots.”  We all live with many things that we merely believe, all of which are so central to ones world view.

Even if we set aside all such types of beliefs, there still remains a broad terrain of human life in which faith and belief remain—even if we ignore all religious matters whatsoever.  Imagine the scientist who’s work on brain neurons depends upon many discoveries made by many other people.  Yes, if it were possible, it would be better for such a person to know all of the details that they accept merely at the word of other scientists.  In all cases, seeing directly is more fulfilling than merely hearing about something.

However, is the scientist better off when he or she knows only what they have experienced directly.  Although it is preferable that he or she knows such facts. However, it is impossible to investigate everything.  Sometimes, one must extend one’s own vision with the vision of someone else.  In a way, the person who thus “takes it on faith” gains a further vision.

Such faith always relies upon the credibility of the person who shares the experience, of course.  For one person to believe on faith what another person says, it is presupposed that the other person is not a liar and actually could have experienced the matter in question.  This means that even the “scientific believer” must take the risk of placing credibility in someone who has witnessed things that he or she has not seen.  While this does not vindicate every kind of faith that people have had, it does provide a telling sign that faith, as such, is not always the refuge of the ignorant.  Indeed, it is an important part of all of our lives, even the lives of scientists, who’s daring and investigative work is rarely criticized as being a refuge for ignorance!

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:

all of which are so central to ones worldview

all of which are so central to one's worldview

all of whom are so central to one's worldview

NO CHANGE

all of which are so central to ones' worldview

Correct answer:

all of which are so central to one's worldview

Explanation:

There are two issues with this selection, though one is very minor. The expression "world view" should be combined into the word "worldview." All of the options, however, fix this error. What is also needed is the alteration regarding the word "ones." This is really a possessive form of "one." Hence, you need to place an apostrophe after the "e" in the word, forming "one's."  

Example Question #665 : Punctuation Errors

The rainforest in Borneo which is home to a declining orangutan population is in danger because of the slash and burn agriculture practices of palm oil plantations. As a student of environmental science and policy, I had the opportunity to travel to Borneo with a team of scientists and learn more about the situation.  It was my first time visiting the rainforest, and I was excited to hike, camp, and learning.   At night, we cooked dinner over a small camp stove, but during the day we ate plants along the trail. The biologists's extensive training in botany helped them identify which plants were edible during their trek through the rainforest.  I felt very fortunate to see this beautiful, endangered forest. One of the scientists told me that much of the trails in the forest are impassable during the rainy season. After a few days of trekking, we arrived in a part of the forest that was supposed to be a protected area.  However, the local minister of forestry was known for catering to the wishes of large palm oil plantation owners. The minister was determined to support the lucrative palm oil industry, irregardless of the costs. Consequently, he had recently allowed the area’s largest company to conduct slash-and-burn farming within the boundaries of the protected area. The scientists told me that these practices not only harmed orangutan habitats, and they contributed to global warming by releasing large amounts of carbon dioxide when peat burns on the forest floor.

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:

biologists

biologist

NO CHANGE

biologist's

biologists'

Correct answer:

biologists'

Explanation:

"Biologists" is a plural noun ending in "s" so in order to make it possessive, you put an apostrophe after the s (but do not add an additional s).

Example Question #111 : Apostrophe Errors

Over winter break, our AP Spanish class took a trip to South America to practice the language and learn more about different Spanish-speaking cultures.  Before we left, every student had to get their vaccinations for yellow fever and typhoid. Our first stop was Bolivia. When we landed at El Alto airport the highest in the world, we could see the city of La Paz sprawling up the hillsides in the shadow of the Andes.   The first day in La Paz, we went to the Witches’s Market, run by local yatiri. The yatiri are medical practitioners who perform healing rituals in they’re communities. At the market, we saw dried frogs, llama fetuses, herbs, and seeds, used in various rituals. After we visited La Paz, we traveled to Cochabamba.  Cochabamba is Bolivia’s culinary capital, with delicious specialties such as salteñas and rellenos. In Cochabamba, we also climbed 1400 steps to see the Cristo de La Concordia statue, the tallest of it’s kind in South America. Next, we visited the salt flats of Uyuni.  Several lagoons dotted the high desert landscape, some of who were full of flamingos!

 

On our way out of Bolivia, we stopped at Lake Titicaca on the Peruvian border. Because the lake’s elevation is over 12,000 feet, some of my classmates experienced a bit of altitude sickness.  Despite the altitude sickness, everyone said they loved seeing the beautiful scenery and visiting the mysterious “floating islands” made of reeds.   When we crossed the border into Peru, one of my classmates thought she had lost her passport. I would of had a panic attack! She ended up finding it buried in a pocket of her backpack and we were on our way. 

 

My favorite part of Peru was our trek to the ancient Incan ruins of Machu Picchu. We spent four days hiking in the Andes on a trail to the ruins. Our guides, whom spoke Spanish, English, and Quechua, were very knowledgeable about the history, flora, and fauna in the region.  Upon waking up the next morning, a beautiful sunrise greeted us and cast the mountains in its soft pink glow. After we explored the ruins, we took a train ride back to Cuzco.  The next day, we flew to Lima and prepared to return home. I was sad to leave, but I know I would be back some day!

Select the answer choice that best corrects the bolded, underlined portion of the passage. If the sentence is correct as is, select NO CHANGE.

Possible Answers:

we went to the Witchs Market,

we went to the Witche's Market,

we went to the Witch's Market,

NO CHANGE

we went to the Witches' Market,

Correct answer:

we went to the Witches' Market,

Explanation:

To make a plural noun ending in "s" possessive, simply add an apostrophe to the s. You do not need to add an additional s. Witch's is incorrect because it changes the subject from plural to singular (but for a singular subject would be ok). The other incorrect choices either misplace the apostrophe or do not include one at all.

Example Question #672 : Punctuation Errors

The Common Good: The United Aim of Many” [22]

Among the many topics that are misunderstood [16] in political science, and political philosophy, the notion of the “common good” ranks foremost. Often, we think of the common good as being nothing more than getting “the most things for the most people.” For example, when a person makes multiple millions of dollars, people will often say, [17] “He should give back some of that money, for the sake of the common good.” Whether or not such people [18] should do this with his money, this is really an improper use of the expression the common good.

A better way to understand the common good is to think about common ends or common goals. An example will help to explain this. Think of a group of musicians on a stage. If all of these people came together to practice in the same room, we wouldn’t call them a symphony. [19] A mass of people just playing any music whatsoever are not a symphony. A symphony is an organized group; a mass of people is just a mass of people. Nothing physically differs regarding the mass of people and the symphony. [20] They are both made up of the same “stuff,” namely a group of musicians.

However, a common good changes [21] this mass into something that they never could be without that common good. [22] When these musicians come together to play the Dies Irae of Mozart, they become something that they never were as individuals.  Each member of the group uses his or her personal skill for the sake of a new, common performance. Perhaps the tuba player loves to play loudly.  Perhaps the lead violinist loves playing quickly.  These preferences must be channeled and limited for the sake of the common enterprise of playing Mozart’s stirring piece of music. [23] The desires of the individual instrumentalists, whom play the music, no longer reigns supreme.

The common good unites this group. If you were to ask the tuba player, what are you doing, he would answer, “Taking part in the symphonic playing of the Dies Irae.” [24] Then, if you were to ask any other musician the same question, he or she would answer in the same way. The answer would not be, “playing the Dies Irae my way.” If that were the answer, the musician would not be part of the symphony. He or she would be doing something private, not something that is truly common.

How should underlined selection [22] be changed?

Possible Answers:

When these musicians' come together to play the Dies Irae of Mozart, they become something that they never were as individuals.

When these musicians' come together to play the Dies Irae of Mozart, they became something that they never were as individuals.

When these musicians came together to play the Dies Irae of Mozart, they become something that they never were as individuals.

NO CHANGE

Correct answer:

NO CHANGE

Explanation:

As written, there are no errors in this sentence. All of the tenses are fine, and the word "musicians" does not require an apostrophe.

Example Question #121 : Apostrophe Errors

“John Adams—A Forgotten American Founder”

Sadly, the great exploits of important [46] men and women is often forgotten in the mists of history. The myths and historical tales of a nation can lead the people to forget [47] some of their most important founders and national heroes. In the United States of America, this kind of forgetfulness has occurred in the case of the Founding Father, John Adams. For a number of reasons, President Adams [48] had been forgotten. Recounting the [49] tales of the nations’ founding, many remember figures like George Washington, Thomas Jefferson, and Benjamin Franklin. [50] However, during those early years of the republic, Adams was a pivotal figure in assuring independence to the burgeoning nation.

[51] During the debates concerning the Declaration of Independence, Adams was something of a “chief orator,” tirelessly attempting to convince the gathered parties of the importance of declaring independence from England. [52] Adams a temperamental and passionate man, was the perfect person to fill such a role. In contrast to the judicious Franklin and the controlled and quiet Jefferson, he was fit for performing such oratorical shows and bombasts. [53] Although he joined Jefferson and Franklin on the drafting committee for the declaration, his most important work during this time was arguably this long project of oratory.

[54] In addition, many forget the lonely years Adams spent as a minister to France and as the first minister to England. What a difficult affair such posts would have been at the time. [55] As the minister to France, what weight could he have had with the court of such an old European nation? Furthermore, Adams [56] was not temperamentally [57] suited for French courtly customs being a stern and somewhat moralistic man. [58] Then, to be sent to England—how difficult that must have been. As the minister on behalf of a once-rebel nation, how could he stand before the Court of King James? Nevertheless, Adams served his [59] post nobly and deserves great recognition for this devoted service to his young nation.

Choose the answer that best corrects section [49].

Possible Answers:

NO CHANGE

the tales of the nations's founding

the tale of the nations' founding

the tales of the nation's founding

Correct answer:

the tales of the nation's founding

Explanation:

Since the sentence is speaking of only one nation, you must use "nation" as the base for the possessive form. Once you have this base, you can then merely add the apostrophe and s, giving you "nation's." That is all that is needed!

Example Question #1 : Quotation Mark Errors

Adapted from Great Expectations by Charles Dickens (1861)

As she applied herself to set the tea-things, Joe peeped down at me over his leg, as if he was mentally casting me and himself up and calculating what kind of pair we practically should make, under the grievous circumstances foreshadowed. After that, he sat feeling his right-side flaxen curls and whisker, and following Mrs. Joe about with his blue eyes, as his manner always was at squally times.

My sister had a trenchant way of cutting our bread and butter for us, that never varied. First, with her left hand she jammed the loaf hard and fast against her bib, where it sometimes got a pin into it and sometimes a needle, which we afterwards got into our mouths. Then, she took some butter (not too much) on a knife and spread it on the loaf, in an apothecary kind of way, as if she were making a plaster.  She used both sides of the knife with a slapping dexterity and trimming and moulding the butter off round the crust. Then, she gave the knife a final smart wipe on the edge of the plaster and then sawed a very thick round off the loaf: which she finally, before separating from the loaf, hewed into two halves, of which Joe got one and I the other.

On the present occasion, though I was hungry, I dared not eat my slice. I felt that I must have something in reserve for my dreadful acquaintance, and his ally the still more dreadful young man. I knew, “Mrs. Joe's housekeeping to be of the strictest kind,” and that my larcenous researches might find nothing available in the safe. Therefore, I resolved to put my hunk of bread and butter down the leg of my trousers.

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

Possible Answers:

I knew, “Mrs. Joe's housekeeping was of the strictest kind,” and

NO CHANGE

I knew, “Mrs. Joe's housekeeping to be of the strictest kind”, and

I knew Mrs. Joe's housekeeping to be of the strictest kind and

Correct answer:

I knew Mrs. Joe's housekeeping to be of the strictest kind and

Explanation:

There is no need for the set of quotation marks in the passage. Almost always, "know" is used with indirect quotations or statments. Later in the sentence, the author introduces an indirect statement by using "that." This thought is also indirectly mentioned, though there is no "that" used. Therefore, no quotation marks are necessary.
