Example Question #201 : Other Phrase, Clause, And Sentence Errors

“Intellectual Virtues”

Whenever someone talks about being “virtuous,” we immediately think of someone whose very moral.  Perhaps we even think of people who are a bit boring for virtuous people can appear to have no fun at least in the popular imagination.  Whatever the case might be, almost any reader would be surprised to see the expression “intellectual virtues.”  What could this expression mean to designate!  At best, most people would say, “Such virtues must describe people for who knowledge is combined with devotion and rigorous discipline.”  That is; they would seem to describe the person who has a disciplined character in addition to being intelligent.

However, in ancient and medieval philosophy, certain intellectual capacities were considered virtues.  These character traits were not quite the same as moral character traits or virtues.  To understand this idea, it can be helpul to consider two example people, one whose skills are the fruit of a so-called intellectual virtue and the other whose skills are not.

It is easier to start with the person who does not have a given intellectual virtue.  We all know someone who is not very good at math, that is, someone for who math is difficult even though he or she might be quite skilled at many other tasks   It makes sense to say that this person doesn’t have an intellectual virtue.  Likewise, think of the person who is only able to memorize formulas.  Such a person is often very good at working through many problems with deft skill.  This person seems to be a “wiz” at geometry and algebra, quickly solving equations and proofs. 

However, this latter person might suddenly be presented with a difficult, new problem.  When we notice that he or she does not have the creative skill and insight to solve the problem, we realize that he or she does’nt have a so-called “intellectual virtue.”  This person merely has a habit—a particular skill that is helpful but does not indicate true and complete mathematical knowledge.  The person who is able to understand the mathematics and creatively apply this knowledge to solve new problems.  This person has a true intellectual virtue.  They have a particular ability for intellectual insight, able to probe the difficult domain of this topic.  This is much more noble as the mere habit of being able to balance equations and repeat facts about geometric figures!

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:

The person who is able to understand the mathematics and creatively apply this knowledge to solve new problems: this person has a true intellectual virtue.

The person, who is able to understand the mathematics and creatively apply this knowledge to solve new problems, this person has a true intellectual virtue.

The person who is able to understand the mathematics and creatively apply this knowledge to solve new problems is the one who has a true intellectual virtue.

The person who is able to understand the mathematics and creatively apply this knowledge to solve new problems; this person has a true intellectual virtue.

NO CHANGE

Correct answer:

The person who is able to understand the mathematics and creatively apply this knowledge to solve new problems is the one who has a true intellectual virtue.

Explanation:

The first sentence in this pair of sentences is actually a fragment. It does not state a complete thought. The various options that use colons and semicolons do not overcome this issue, as you would need the first clause to be wholly independent in some fashion. Thus, the only correct option is the one that modifies the content significantly enough to present one combined, complete independent clause.

Example Question #1711 : Correcting Grammatical Errors

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

Patrick who has done an excellent job planning the upcoming conference, and will be in attendance for all four sessions next weekend.

Possible Answers:

doing an excellent job planning the conference,

he has done an excellent job planning the conference,

has done an excellent job planning the conference,

NO CHANGE

having done an excellent job planning the conference,

Correct answer:

has done an excellent job planning the conference,

Explanation:

The sentence needs a predicate to match with "and will attend" in the second half.

 "doing" and "having done" both create sentence fragments.

 Inserting a main clause into the modifier's position creates a run-on sentence.

Example Question #1712 : Correcting Grammatical Errors

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

My favorite part of the vacation by far the helicopter tour of the island.

Possible Answers:

My favorite part of the vacation by far, the helicopter tour of the island.

NO CHANGE

My favorite part of the vacation by far. The helicopter tour of the island.

My favorite part of the vacation by far was the helicopter tour of the island.

The helicopter tour of the island by far, my favorite part of the vacation.

Correct answer:

My favorite part of the vacation by far was the helicopter tour of the island.

Explanation:

This question asks you to correct a sentence fragment error. The original sentence, "My favorite part of the vacation by far the helicopter tour of the island," contains no verb and therefore is a fragment. The addition of the verb "was" makes it a complete sentence.

Example Question #1713 : Correcting Grammatical Errors

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

I was always certain that I wanted to be an engineer. From my first day in college.

Possible Answers:

From my first day in college; I was always certain that I wanted to be an engineer.

NO CHANGE

I was always certain that I wanted to be an engineer from my first day in college.

I was always certain that I wanted to be an engineer; from my first day in college.

From my first day in college. I was always certain that I wanted to be an engineer.

Correct answer:

I was always certain that I wanted to be an engineer from my first day in college.

Explanation:

This question asks you to correct a sentence fragment. A complete sentence must contain a main verb, so the sentence "From my first day in college" is a fragment. In this case, the period should be removed to form a single complete sentence. The first part of the sentence, "I was always certain that I wanted to be an engineer," contains the main verb "was," and the second part of the sentence forms a dependent clause. 

Example Question #1714 : Correcting Grammatical Errors

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

While they watched the sunset, John and Amy so amazed by all the colors.

Possible Answers:

While they watched the sunset, John and Amy amazed all the colors.

John and Amy, while they watched the sunset, so amazed at all the colors.

While they watched the sunset, John and Amy were so amazed by all the colors.

NO CHANGE

John and Amy so amazed by all the colors, while they watched the sunset.

Correct answer:

While they watched the sunset, John and Amy were so amazed by all the colors.

Explanation:

This question asks you to correct a sentence fragment. The sentence as written contains no main verb and therefore is a fragment. The verb "watched" is part of the dependent clause, "while they watched the sunset," and therefore does not function as the sentence's main verb. The addition of the main verb "were" in the independent clause corrects the sentence fragment.

Example Question #204 : Other Phrase, Clause, And Sentence Errors

Josh suffered from a fear of dogs ever since he is a little boy. He would shiver in his boots thinking of a dog barking at him, biting him, or that could chase him. He had never met a single dog he liked. The scarier dog he had ever seen was Mr. Green’s dog, whom he had to pass every day. On his way to school. This dog barked so loudly it made Josh’s hairs stand on end.

She said that there was no need to be afraid. Josh’s mom told him that dogs only barked because they were excited to see him. She told him that he just needed to be confident and not act afraid of this dogs’ barking, and speak in a reassuring tone. Then the dog would quiet down and act more friendly.

Josh felt that neither confidence or a reassuring tone would make any difference. He didn’t think he would ever get over his fear. However, one day he had enough. Barking for hours, he realized the dog was bored and just needed a friend. He wasn’t sure if his mother’s advice would prove true? Hiding his fear, he approached the dog and spoke to it in a reassuring tone. To his surprise, the dog wagged it’s tail and quieted down right away. 

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:

whom he had to pass every day; on his way to school

whom he had to pass. Every day on his way to school

whom he had to pass? Every day on his way to school

NO CHANGE

whom he had to pass every day on his way to school

Correct answer:

whom he had to pass every day on his way to school

Explanation:

This question asks you to correct a sentence fragment. As written, the sentence "On his way to school" contains no verb, and therefore it is a fragment. To correct this error, we can eliminate the period and connect it to the preceding sentence to form a single complete sentence. 

Example Question #1715 : Correcting Grammatical Errors

Choose the answer that best corrects the underlined portion of the text. If the underlined portion is correct as written, select “NO CHANGE.”

The researchers determined a correlation between the chemical and altered behavior. Quite minor, however.

Possible Answers:

NO CHANGE

However, quite minor.

The correlation was quite minor, however.

Just a minor correlation, however.

However, quite a minor correlation.

Correct answer:

The correlation was quite minor, however.

Explanation:

This question asks you to correct a sentence fragment. The original sentence "Quite minor, however" is a fragment--it contains neither a subject nor a verb. The simple addition of a subject, "The correlation," and a verb, "was," corrects the sentence fragment. All of the other choices given here are still fragments, missing either a subject and/or verb.

Example Question #202 : Other Phrase, Clause, And Sentence 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:

Although it is preferable that he or she knows such fact, it is impossible to investigate everything.

NO CHANGE

Although it is preferable that he or she knows such facts; however, it is impossible to investigate everything.

Although, it is preferable that he or she knows such facts. However, it is impossible to investigate everything.

Although, it is preferable that he or she knows such facts; however, it is impossible to investigate everything.

Correct answer:

Although it is preferable that he or she knows such fact, it is impossible to investigate everything.

Explanation:

As it is written in the passage, note that the clause, "Although it is preferable that he or she knows such facts," is not a complete thought. Therefore, you need to get rid of this fragment. The only option that addresses this issue totally is the one that combines the two sentences provided, eliminating the word "however." All of the other options leave the fragment in place (in various ways). Hence, they do not solve the issue! 

Example Question #1716 : Correcting Grammatical Errors

[1] Some people are excited, some people are just annoyed. [2] Being called to jury duty can inspire a range of different emotions. [3] Unsure how long the trial will take, a call to jury duty can be stressful for people who can’t afford to miss work or school.

Some people will be making attempts to get out of jury duty. However, most will still need to serve. Fortunately, many cases are settled before going to trial and is not uncommon for trials to just last only one day. Either way, once you have served on a jury, you won’t have to do it again for a while!

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:

NO CHANGE

it is not

being not

not being

not

Correct answer:

it is not

Explanation:

This question asks you to correct a sentence fragment. The original phrasing, "and is not uncommon for trials to just last only one day," leaves the second half of the sentence without a main verb. To correct this error, we can add the verb "is," so the phrase reads, "and it is not uncommon for trials to just last only one day."

Example Question #62 : Sentence Fragment And Sentence Combination Errors

“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:

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.

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.)

NO CHANGE

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!

Correct answer:

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.

Explanation:

This set of sentences is a bit rambling in its expression of the thought it wishes to convey. Nevertheless, it should be obvious that the first sentence is a fragment. The clause starting with "when" and the clause starting with "if" both are subordinate clauses. You need to combine the first fragment with the second sentence. This will at least give you one complete thought—though it is a bit rambling!
