Example Question #143 : Verb Tense Errors

“Mathematics and Learning”

What subject should be learned first?  The question rightly troubles anyone who’s interest is in education.  Of course, young children often must learn in a very basic and rote fashion, applying their apt memorization skills to simple tasks that will serve them very well in later years when they go one to apply such knowledge to more complex topics.  However, when the time comes to designing curricula, an important question must be answered for older students, namely “What is most important first topic in these students’s education?”

An argument can be made for the use of mathematics as a tool for teaching students how to reason more clearly.  This is not because mathematics is the basis of all knowledge.  Indeed not.  There are many important subjects including not only the humanities like poetry and history but sciences like biology and physiology too.   These topics are not strictly speaking mathematical in nature, even though mathematics can be used in it in many ways.

Our minds are best geared for learning things that we can sense, things that are visible and tangible.  Although mathematics is abstract, it can begin with this kind of sense derived experience.  Beginning with simple everyday examples, children can be taught the more abstract and difficult skills that must be learned for the sake of the development of mathematical skills.  In the process of learning these topics, the children will begin to learn important rules about reasoning.  He or she will learn how several propositions can serve as the basis for conclusions.  They will learn how certain properties are related to various geometric figures and arithmetical rules.  Although much of this will be memorized at first, with time, they will have the opportunity to see that human reasoning in mathematical subjects is orderly and logical.  On the basis of such “logical experience,” young learners can then begin to be taught the rules of logic that they have been using all along.  As the medievals used to say, they could go from logica utens, logic used in other subjects, to logica docens logic taught, as a unique, and separate subject.

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:

the rules of logic that they had been using all along

NO CHANGE

the rules of logic that they have used all along

the rules of logic that they were using all along

the rules of logic they have been using all along

Correct answer:

NO CHANGE

Explanation:

It might be tempting for you to choose the past perfect form "had been using." Whenever you are discussing something that is more remotely in the past compared to another past action, this is the form you use to express this kind of temporal sequence. Note the main verb in the sentence: "Young learners can then begin." Since this sentence is in the present tense, the "present perfect" form that is already in the sentence is fine.

Example Question #1581 : 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."

Explanation:

The past hypothetical construction requires a past perfect (had spent) in the subordinate clause.

Example Question #1582 : 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."

After he went to the grocery store, Frank stops at the hardware store to pick up some nails.

Possible Answers:

NO CHANGE

stopped

will stop

stop

stopping

Correct answer:

stopped

Explanation:

This question asks you to correct a verb tense error. The first part of the sentence, "After he went to the grocery store," uses the past tense verb "went." Therefore, the verb in the second part of the sentence should also use the past tense form, "stopped." 

Example Question #1583 : 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."

Before I took the exam, I purchased several preparation manuals containing both practice tests and review exercises.

Possible Answers:

had purchased

will purchase

would purchase

am purchasing

NO CHANGE

Correct answer:

had purchased

Explanation:

Because the sentence features two past tense actions, "took" and "purchased" that are being presented in the opposite order in which they were completed, it is necessary to use the past perfect "had purchased" to establish that this action was completed first.

Example Question #1584 : 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."

Billy gone to the ocean once before in his life.

Possible Answers:

had went

NO CHANGE

going

had gone

go

Correct answer:

had gone

Explanation:

This question asks you about the correct tense of a verb. The use of the word "before" in this sentence indicates that the past perfect tense should be used. The past perfect tense is used to show that a past event happened before something else happened. The correct past perfect formation of the verb "to go" is "had gone."

Example Question #151 : Verb Tense Errors

Josh suffered from a fear of dogs 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:

NO CHANGE

having been a little boy, he

he had been a little boy

he was a little boy

he, being a little boy

Correct answer:

he was a little boy

Explanation:

This question asks you to correct a verb tense error. To find the correct answer, we can look at the context of the rest of the sentence. Since the sentence includes the past tense verb, "suffered," it is correct to use the past tense form, "he was a little boy."

Example Question #201 : Usage 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:

one day he had had enough

one day he was having enough

one day he will have had enough

one day he will have enough

NO CHANGE

Correct answer:

one day he had had enough

Explanation:

This question asks you about the correct tense for a verb. The past perfect, "had had," should be used here to convey that a past action occurred before another past action. The phrase "had enough" must therefore be preceded with another "had" to communicate that it took place before Josh's next action, realizing the dog was bored.

Example Question #1241 : 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:

have made

NO CHANGE

will make

making

made

Correct answer:

will make

Explanation:

This question asks you about the correct tense to use for a verb. This passage is in present tense, and to express the fact that people will attempt to get out of jury duty once they have been called, we should use the future tense formation, "will make." It is not necessary to use a gerund to express continuous action, as in the original, "will be making." 

Example Question #1587 : 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 above 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:

NO CHANGE

Unlike the cases discussed earlier, children will have little

Unlike the cases discussed earlier, children had had little

Unlike the cases discussed earlier, children have had little

Unlike the cases discussed earlier, children had little

Correct answer:

Unlike the cases discussed earlier, children will have little

Explanation:

As written, the sentence uses the future perfect tense. This is a tense that is rarely used in English. It indicates something that happened in the future but before something else. Hence, you would say, "Before I will eat the food, I will have bought it." Generally, we say, "Before I eat the food, I will buy it." Still, the more proper form is correct—but not for this question! The general point is that children will not have the chance to repay their parents directly and equally for all that they have done. It doesn't make sense to place this action in any sort of past tense, given the form of the sentence as a whole. Hence, the best option is the one that uses the future tense only—"will have."

Example Question #1242 : Correcting Grammatical 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 written, select NO CHANGE.

Possible Answers:

but I knew I will be back

but I had known that I would be back

but I was to know I would be back

NO CHANGE

but I knew I would be back

Correct answer:

but I knew I would be back

Explanation:

The author has been speaking in the past tense throughout the passage, and needs to maintain that verb tense here with the past tense "knew" instead of present tense "know."  When using the word "knew" in this sense, "would" rather than "will" is the correct future tense to use.
