GRE Mock Test (New Pattern) - 4 - GRE MCQ

Now, let us look at the meaning of the verbs in the options.

A. incriminates – to make (someone) appear guilty of a crime or wrongdoing

B. valorizes – to give or ascribe value or validity to

C. indicts – to formally accuse of or charge with a crime

D. abrogates – to abolish by authoritative action

E. rescinds – to take away

'Valorizes,' which means to give validity to something, is the correct answer. 'Incriminates,' 'indicts,' and 'abrogates' are opposite to what the context requires. 'Rescinds' does not go with the intended meaning of the sentence.

Further down this sentence, we see that '(i) __________ analgesic treatment' is compared with 'treatment started after surgery.'

For two things to be compared, they must be unique or opposite to one another.

This means, '(i) __________ analgesic treatment' is not started after surgery. Therefore, either this treatment is started before the surgery or during the surgery.

Thus, 'Blank (i)' should be filled with a word that either means something like 'pre-surgery' or 'during-surgery'.

With this idea in mind, we evaluate the three options for Blank (i):

A. ameliorative - this means 'that which soothes pain [or another negative condition] or makes it more bearable'. This word is a synonym of 'analgesic' and doesn't carry any connotation of time (pre - or during -). Hence, we can reject this choice.

B. incipient - this means 'beginning to exist'. The phrase 'incipient analgesic treatment' would mean 'analgesic treatment that is only just starting or beginning to exist.' The opposite of 'incipient treatment' would be 'fully-developed treatment'. Therefore, this word too doesn't convey the meaning that we are looking for.

C. preemptive - this means 'that which is done ahead in time to prevent a possible bad event from happening.' So, 'preemptive analgesic treatment' would mean 'analgesic treatment that is started before the surgery or pain occurs. In this sense, it conveys the opposite of the phrase 'analgesic treatment started after the surgery.' This word fits in our intuited meaning of Blank (i).

Let is now find out the correct option for Blank (ii).

A simpler version of the question statement is:

"Many surgeons continue to advocate X despite the fact that [ABC] have failed to demonstrate (ii) __________ that X is any better than Y."

The key words in the above sentence is 'despite'. This is a contrast word. So, it indicates that the belief of the surgeons is not supported by ABC.

So, [ABC] have failed to demonstrate __________ that X is as good as the surgeons think it to be.

The possible words that can fill Blank (ii) are: clearly, definitively, beyond doubt.

With these words in mind, we'll evaluate the answer choices for Blank (ii):

D. dispassionately - this word means 'calmly or impartially'. Clearly, it doesn't fit the context here and can be rejected.

E. unequivocally - it means 'clearly, unmistakably'. This word fits in our intuited meaning of Blank (ii).

F. intractably - it means 'stubbornly, unmanageably.' To prove or demonstrate something 'Stubbornly/unmanageably' doesn't make any sense and so, this option too can be rejected.

The complete sentence is:

Many surgeons continue to advocate preemptive analgesic treatment despite the fact that clinical studies and meta-analyses have failed to demonstrate unequivocally that such treatment reduces postoperative pain more effectively than one started after surgery.

The correct answer are C and E.

In the sentence, the phrases 'was a towering figure' and 'contemporaries and successors... had to live in his shadow' make it obvious that Johann exercised a lot of 'influence' which was unmatched during his age. Hence, his 'influence' can be said to be 'overpowering' or 'unparalleled'. These two can be apt fill-ins.

Now, let us look at the meaning of the adjectives in the options.

A. insufferable -- too extreme to bear; intolerable

B. overwhelming – huge; formidable; massive

C. uncanny – mysterious; supernatural

D. insurmountable -- too great to be overcome; invisible

E. germane – relevant; connected

'overwhelming' and 'insurmountable' both fit in the blank. 'Insufferable' is incorrect because it is an extremely negative word in the context. 'Uncanny' is incorrect because contextually it is not relevant. 'Germane' is incorrect because it is too shallow for the context. 'Reticent' is incorrect because it rather goes against the context.

The correct answers are B and D.

The sentence talks about MPs being tasked by the High Court with getting the details of their expenses ready for publication. However, there is a caveat attached to this task. The MPs need to publish these details in a certain way. "Modifications" or "changes" could both be good fill-ins for the blank.

Now, let us look at the meaning of the words in the options.

A. compurgation – acquittal from a charge or accusation obtained by statements of innocence given by witnesses under oath

B. ostentation – the pretentious or showy display of wealth and luxury, designed to impress

C. redaction – the process of editing text for publication

D. recension – the revision of a text

E. affectation – a studied display of real or pretended feeling

"Redaction" and "recension" both are words that mean to make changes to a text before it is published; they both fit the blank well. "Compurgation," "ostentation," "affectation," and "repugnance" are all unrelated to the meaning of the sentence.

We can deduce from the sentence that the politicians adopt Franklin's distinction to become a certain kind of men – that is, to derive an advantage. Let us look at the meaning of the words in the options for blank (i).

A. incorrigible - (of a person or their behavior) not able to be changed or reformed

B. peevish - Having or showing an irritable disposition

C. wily - Skilled at gaining an advantage, especially deceitfully

'Wily' fits perfectly in the blank. 'Incorrigible' is opposite to the context implied in the sentence. 'Peevish' seems unrelated.

For the second blank, we require a word that implies an advantage that the politicians will have after adopting Franklin’s distinction. Let us look at the meaning of the words in the options for blank (ii).

D. flagitious - (of a person or their actions) criminal; villainous

E. inscrutable - not readily investigated, interpreted, or understood

F. dubious - Not to be relied upon; suspect

Both 'flagitious' and 'dubious' are negative qualities that the politicians wouldn't want to have. To be inscrutable men is an advantage that they would like to have. Therefore, 'inscrutable' is correct.

Reading the sentence makes it clear that we require a verb for the third blank-in. 'Affect' can be a good fill-in. Let us look at the meaning of the words in the options for blank (iii). The use of does not seem to suggests that the effect could be negative.

G. occlude - Stop, close, or obstruct (an opening, orifice, or passage)

H. tranquillize - have a calming or sedative effect on

I. discommode - Cause (someone) trouble or inconvenience

'George’ is the object of the verb. Since 'occlude' does not take up a person as object, it can be ruled out. 'Tranquilize' means to have a positive effect; it does not go well with the intended meaning. 'Discommode' is the correct answer as it fits perfectly to imply trouble or rattle someone (George here).

The complete sentence is:

That wily politicians might adopt Franklin's distinction between appearance and reality to become inscrutable confidence men did not seem to discommode George.

The correct answers are C, E and I.

Now, let us look at the meaning of the words in the options for blank (i).

A. alcazar – a Spanish palace or fortress of Moorish origin

B. donjon – the great tower or innermost keep of a castle

C. charnel – a building or vault in which corpses or bones are piled

Both "alcazar" and "donjon" mean opposite to what the sentence implies. "Charnel," which means a burial ground, is the correct option.

Coming to the next blank, we require a noun that fits after the phrase "breeding ground" and has a negative meaning.

Now, let us look at the meaning of the words in the options for blank (ii).

D. pestilence – a fatal epidemic disease, especially bubonic plague

E. ascendancy – occupation of a position of dominant power or influence

F. plenitude – an abundance

"Pestilence," which means "a disease" is the correct answer as it fits well before "hate" and works well after the phrase "breeding ground." "Ascendency" and "plenitude" are positive words that mean wealth and abundance and therefore do not fit the blank.

Let us look at the meaning of the words in the options for blank (i).

A. myrmidon – a follower or subordinate of a powerful person

B. abdication – an act of renouncing the throne

C. prepotency – having power or influence greater than others

The use of the word "renounce" suggests that "abdication" is the correct answer. "Myrmidon" is unrelated and "prepotency" is opposite to the meaning of the sentence.

Coming to the next blank, we require a noun that goes well with homage and allegiance. Loyalty could be a good fill-in here. Let us look at the meaning of the words in the options for blank (ii).

D. fealty - formal acknowledgement of loyalty to a lord

E. inconstancy – not faithful and dependable

F. brio - vigor or vivacity of style or performance

"Fealty," which means loyalty, is the correct answer. "Inconstancy" is opposite to the meaning implied in the sentence. "Brio" is unrelated to the meaning implied in the sentence.

Now, we look at the third blank. Since Richard executed a formal deed, relinquishing all royal rights and freeing his people from all obligations, he was free to step down or to have himself dethroned or demoted.

Let us look at the meaning of the words in the options for blank (iii).

G. succored – to be given assistance or aid to

H. deposed – remove from office suddenly

I. slighted – insult (someone) by treating or speaking of them without proper respect

"Succored" and "slighted" are both unrelated to the meaning expressed in the sentence. "Deposed" is the correct answer as the revolutionary is removed from his duty after he executed the deed.

The sentence states that the parliament made a certain kind of return on Monday, and the senators were chirpy and guffawed through the question period. The words chirpy (cheery) and guffaw (chuckle/laugh) tell us that the mood in the parliament was lively and light, so the fill-in, which describes the kind of return that the parliament made, must be a positive word that means the environment was "happy" and "exuberant". The word exuberant can be a good fill-in.

Now, let us look at the meaning of the adjectives in the options.

A. lugubrious – looking or sounding sad and dismal

B. rambunctious – uncontrollably exuberant; boisterous

C. opprobrious – expressing scorn or criticism

D. staid – sedate, respectable, and unadventurous

E. ebullient – cheerful and full of energy

Both 'rambunctious' and 'ebullient' fit in the blank well. The words 'lugubrious' and 'opprobrious' are negative and therefore do not fit in the blank. 'Staid' and 'unflagging' are unrelated to the meaning of the sentence and therefore do not convey the correct meaning.

The correct answers are B and E.

The sentence states that India is a diverse country and should not be thought to have one composite (unified) culture as it is not only untrue but also encourages some type of tendencies. The phrase "not only untrue but also dangerous, for it tends to weaken national unity" implies that these tendencies are harmful and negative for the country. The fill-in could be a word that implies something that breaks or divides.

Now, let us look at the meaning of the adjectives in the options.

A. separatist – relating to the idea of separating a certain group of people from a larger body on the basis of ethnicity, religion, or gender

B. fissiparous – Inclined to cause or undergo division into separate parts or groups

C. portentous – of momentous significance

D. rapacious – aggressively greedy or grasping

E. sycophantic – behaving or done in an excessively obedient or attentive way in order to gain advantage

'Separatist' and 'fissiparous' both fit in the blank. 'Portentous' and 'rapacious' are unrelated to the context of the sentence. 'Sycophantic' and 'obsequious' both mean the same, but they are opposite to what the sentence implies.

The correct answers are A and B.

injuries that they can conceal. If the number of injuries that cannot be concealed such as injuries requiring immediate emergency care—has not declined in the same period, that could help bolster the claim that the decline in overall reported injuries may be a result of concealable injuries going unreported rather than an actual decline in workplace injuries in general, so Choice A is correct.

If employers have to provide financial compensation to employees injured on the job, employees would have an incentive to report injuries. More reported injuries would not support the author’s argument, making Choice B incorrect. Choice C is incorrect because the fact that some injuries that cannot be concealed do not result in lost time or changed responsibilities has nothing to do with whether concealable injuries are going unreported. While a decline in dangerous occupations could well result in a decrease in workplace injuries, this fact would challenge the author’s argument, not support it, so Choice D is incorrect. Similarly, if employers with safety incentive programs do not see any drop in reported injuries compared to employers

without such programs, the author’s argument would be weakened, not supported, making Choice E incorrect.

Since p = r² + t, the value of (−1)p depends on whether r² + t is odd or even.

If r is an odd integer, then r² is an odd integer and, since r and t are consecutive integers, t is an even integer. In this case, p is the sum of an odd integer and an even integer and is therefore an odd integer.

Similarly, if r is an even integer, then r² is an even integer and t is an odd integer. In this case, p is the sum of an even integer and an odd integer and is therefore an odd integer.

In both cases, p is an odd integer. It follows that (−1)^p = −1, and the correct answer is Choice C.

You get f(4) = 3(5)² or 75. Since Quantity B is 75, the correct answer is Choice C.

denominator of the fraction by 39 to get . From the simplified equation, you can see that x is an integer if and only if y is a factor of (2)(4)(5)(7)(11). To answer the question, you need to check each of the answer choices until you find the one that is a factor of (2)(4)(5)(7)(11).

Choice A: 15. Since 15 = (3)(5) and 3 is not a factor of (2)(4)(5)(7)(11), neither is 15.

Choice B: 28. Since 28 = (4)(7) and both 4 and 7 are factors of (2)(4)(5)(7)(11), so is 28.

You can check the other choices to confirm that none of them is a factor of (2)(4)(5)(7)(11). The correct answer is Choice B.

1.4 million. The number of Internet users in the United States is not explicitly given, but you know from the circle graph that it was equal to 51% of the number of Internet users worldwide.

From the bar graph, the number of Internet users in Europe was 27.3 million, and from the circle graph this number was 29% of Internet users worldwide. It follows that the number of users worldwide was 27.3/0.29 million, which is approximately 94 million.

Thus the number of users in the United States was 51% of 94 million, or approximately 48 million.

Since the numbers of Internet users in the United States and in Italy were about 48 million and 1.4 million, respectively, it follows that the number in the United States was approximately 48/1.4 times the number in Italy. Since 48/1.4 is approximately 34, and the answer choice closest to 34 is 35, the correct answer is Choice E.

Factoring the quadratic equation x² − 5x + 4 = 0, you get (x − 1)(x − 4) = 0, so the two solutions are either a = 1 and b = 4 or a = 4 and b = 1. Note that a and b are interchangeable in the expression so the value of the expression will be

the same regardless of the choices of a and b. Thus

and the correct answer is 5/2.

The only pairs of positive odd integers x and y that are less than 10 and satisfy the condition x + y < 10 are the pair 1 and 3, the pair 1 and 5, the pair 1 and 7, and the pair 3 and 5. Since z = x + y, it follows that the sum of x, y, and z is equal to 2z. The sum for each of the four possible pairs is found as follows

• 1 and 3: z = 4, and the sum of x, y, and z is 2z, or 8.

• 1 and 5: z = 6, and the sum of x, y, and z is 12.

• 1 and 7: z = 8, and the sum of x, y, and z is 16.

• 3 and 5: z = 8, and the sum of x, y, and z is 16.

Thus the only possible values of the sum of x, y, and z are 8, 12, and 16. The correct answer consists of Choices A, D, and E.

water, so that when the water freezes, the ice will not rise above the top of the tank. Based on the assumption that the volume of water increases by 10 percent when it freezes and the fact that the length and width of the tank will not change, the maximum height of the ice is 1.1x centimeters. Since the height of the tank is 270 centimeters, it follows that 1.1x = 270, or, to the nearest whole number, x = 245. The correct answer is Choice D.

Quantity A: (2x⁻⁴)(3x²) = 6 / x²

Quantity B: 24x / 4x² = 6 / x

So comparing Quantity A with Quantity B is the same as comparing 6 / x² with 6 / x.

Since you are given that x > 0 and x ≠ 1, and the quantities to be compared involve fractions and exponents, it is reasonable to consider two cases: 0 < x < 1 and x > 1.

Case 1: 0 < x < 1. If x is a number that satisfies 0 < x < 1, then x² < x. Therefore 6 / x² > 6 / x and Quantity A is greater than Quantity B.

Case 2: x > 1. If x is a number that satisfies x > 1, then x² > x. Therefore 6 / x² >< 6 / x and Quantity B is greater than Quantity A.

In one case Quantity A is greater, and in the other case Quantity B is greater. Thus the correct answer is Choice D.

length s is s². Since you are given that an isosceles right triangle and a square have the same area R, it follows that x² / 2 = s² and so x = √2s.

Since √2 is greater than 1, the length of a leg of the triangle is greater than the length of a side of the square. The correct answer is Choice A.

Here’s a plain‐text derivation:

1. Since j and k are even, the even numbers from j up to k (inclusive) occur every 2 units.

2. The total “span” from j to k is k – j.

3. Stepping by 2 each time gives (k – j) ÷ 2 steps, but that counts how many “gaps” of size 2 there are between j and k.

4. To count the even numbers themselves from j through k inclusive, you add 1:
   number inclusive = (k – j) ÷ 2 + 1

5. You want only those strictly between j and k, so drop the two endpoints j and k:
   number between = [(k – j) ÷ 2 + 1] – 2
   = (k – j) ÷ 2 – 1
   = (k – j – 2) ÷ 2

So the answer is
(k – j – 2) ÷ 2
which is choice (a).

Recall that the standard deviation of the numbers in a list is a measure of the spread of the numbers about the mean of the numbers. The standard deviation is directly related to the differences |x − m| between the mean m and each number x in the list. The smaller the differences, the smaller the standard deviation. Thus to answer the question, look at the values of |x − m| for each of the five bird species in the answer choices and determine which species has the smallest values.

Choice A, Cardinal. For cardinals, the numbers of sightings are 30, 18, 11, and 20. The mean is approximately 20. Therefore the differences between the mean and the four numbers in the list are approximately 10, 2, 9, and 0.

Choice B, Junco. For juncos, the numbers of sightings are 12, 0, 0, and 6. The mean is approximately 5. Therefore the differences between the mean and the four numbers in the list are approximately 7, 5, 5, and 1.

Choice C, Robin. For robins, the numbers of sightings are 6, 12, 28, and 18. The mean is 16, and the differences between the mean and the four numbers in the list are 10, 4, 12, and 2.

Choice D, Sparrow. For sparrows, the numbers of sightings are 20, 19, 23, and 22. The mean is 21, and the differences between the mean and the four numbers in the list are 1, 2, 2, and 1.

Choice E, Wren. For wrens, the numbers of sightings are 0, 18, 30, and 12. The mean is 15, and the differences between the mean and the four numbers in the list are 15, 3, 15, and 3.

Consider how consistently small the differences are for the numbers of sightings of sparrows as compared to the differences for the other four species. From this you can judge that the numbers of sightings of sparrows has the least standard deviation. Thus the correct answer is Choice D.

Since you know that the probability of event A is 1/2 and the probability of event B is 1/3 but you are not given any information about the relationship between events A and B,

you can compute only the minimum possible value and the maximum possible value

of the probability of the event A ∪ B.

The probability of A ∪ B is least if B is a subset of A; in that case, the probability of A ∪ B is just the probability of A, or 1/2

The probability of A ∪ B is greatest if A and B do not intersect at all; in that case, the probability of A ∪ B is the sum of the probabilities of A and B, or 1/2 + 1/3 = 5/6.

With no further information about A and B, the probability that A or B, or both, will occur could be any number from 1/2 to 5/6 of the answer choices given, only 1/2 and 3/4 are in this interval. The correct answer consists of Choices B and C.

From the Venn Diagram, you can see that the 30% who are in the band consists of 25% who are in the band but not in the science club, and 5% who are in both the band and the science club. Then you can see that the 20% who are in the science club consists of 5% who are in both the science club and the band, and 15% who are in the science club but not in the band, as shown in the revised Venn diagram below.

Thus 15% / 20% (100%), or 75%, of the students in the science club are not in the band. The correct answer is Choice E.
