Default Re: GRE Logic Questions

Here I am providing you Logic Questions of Graduate Record Examination (GRE), please have a look……

1. Testifying before the Senate committee investigating charges that cigarette manufacturers had manipulated nicotine levels in cigarettes in order to addict consumers to their products, tobacco executives argued that cigarette smoking is not addictive. The primary reason they gave in support of this claim was that cigarette smoking was not regulated by the Federal Drug Administration.

For the tobacco executives' argument to be logically correct, which of the following must be assumed?

(A) Substances that are not addictive are not regulated by
...........the Federal Drug Administration.
(B) The tobacco executives lied when they claimed that
...........cigarette smoking was not addictive.
(C) Some addictive substances are not regulated by the
...........Federal Drug Administration.
(D) There is no scientific proof that cigarette smoking is
...........addictive.
(E) Substances that are not regulated by the Federal Drug
...........Administration are not addictive.

2. A study of native born residents in Newland found that two-thirds of the children developed considerable levels of nearsightedness after starting school, while their illiterate parents and grandparents, who had no opportunity for formal schooling, showed no signs of this disability.

If the above statements are true, which of the following conclusions is most strongly supported by them?

(A) Only people who have the opportunity for formal
...........schooling develop nearsightedness.
(B) People who are illiterate do not suffer from
...........nearsightedness.
(C) The nearsightedness in the children is caused by the
...........visual stress required by reading and other class work.
(D) Only literate people are nearsighted.
(E) One-third of the children are illiterate.

3. There is clear evidence that the mandated use of safety seats by children under age four has resulted in fewer child fatalities over the past five years. Compared to the five-year period prior to the passage of laws requiring the use of safety seats, fatalities of children under age four have decreased by 30 percent.

Which one of the following, if true, most substantially strengthens the argument above?

(A) The number of serious automobile accidents involving
...........children under age four has remained steady over the
...........past five years.
(B) Automobile accidents involving children have decreased
...........sharply over the past five years.
(C) The use of air bags in automobiles has increased by
...........30 percent over the past five years.
(D) Most fatal automobile accidents involving children under
...........age four occur in the driveway of their home.
(E) The number of teenage drivers has increased by 30
...........percent over the past five years.

4. Lycopene, glutathione, and glutamine are powerful antioxidants that neutralize the free radicals that are produced in the body as a result of routine bodily processes. An excess of these free radicals in your system causes rapid aging because they accelerate the rate of cellular damage. Aging is simply the result of this damage. Thus, to slow down aging it is necessary to supplement your diet with these antioxidants on a daily basis.

Which of the following, if true, most seriously undermines the author's contention?

(A) Most persons aren't concerned with the effects of aging
...........until it is too late to do anything.
(B) Exercise associated with normal daily activities effectively
...........neutralizes and dissipates the free radicals that are
...........produced as a result of routine bodily processes.
(C) The cost of antioxidants is exorbitantly high and well
...........beyond the budget of most consumers.
(D) Only overweight people who do not exercise on a daily
...........basis are likely to have an excess of free radicals in their
...........systems.
(E) Smoking cigarettes is one of the main causes of cellular
...........damage in humans.

5. Is it wrong for doctors to lie about their patients' illnesses? Aren't doctors just like any other people we hire to do a job for us? Surely, we would not tolerate not being told the truth about the condition of our automobile from the mechanic we hired to fix it, or the condition of our roof from the carpenter we employed to repair it. Just as these workers would be guilty of violating their good faith contracts with us if they were to do this, doctors who lie to their patients about their illnesses violate these contracts as well, and this is clearly wrong.

The conclusion of the argument is best expressed by which of the following?

(A) Doctors who lie to their patients about their illnesses
...........violate their good faith contracts with their patients.
(B) Doctors often lie to their patients about their illnesses.
(C) Doctors are just hired workers like mechanics and
...........carpenters.
(D) It is wrong for doctors to lie about their patients'
...........illnesses.
(E) Doctors, like mechanics and carpenters, enter into good
...........faith contracts with us when we hire them.

6. The correct response to Question 1 is (E). The tobacco executives' argument can be represented as follows:

Premise: Cigarette smoking is not regulated by the Federal Drug Administration.

Conclusion: Cigarette smoking is not addictive.

The logical gap in the argument that needs to be filled is the link between substances that are regulated by the Federal Drug Administration and substances that are addictive. Moreover, to make the argument logically correct, the link between them must be such that the fact that something is not regulated entails that it is not addictive. Response (E) is equivalent in meaning to the claim that all substances that are not regulated by the Federal Drug Administration are not additive. This is exactly the assumption required to fill the gap in the tobacco executives' argument.

(A) does not fill the logical gap in the tobacco executives' argument. Response (A) is equivalent in meaning to the claim that all substances that are not addictive are not regulated by the Federal Drug Administration. The assumption required to fill the gap in the tobacco executives' argument is that all substances that are not regulated by the Federal Drug Administration are not addictive.

(B) brings in information not mentioned in the passage. The issue of whether or not the tobacco executives lied when they claimed that cigarette smoking is not addictive is irrelevant to the logic of their argument.

(C) does not fill the logical gap in the tobacco executives' argument. The fact that some of the substances that are regulated by the Federal Drug Administration are not addictive is irrelevant to the tobacco executives' argument. Their conclusion is based on the premise that cigarette smoking is not regulated—not that it is regulated.

(D) brings in information not mentioned in the passage. The claim asserted in response (D), if true, could serve as an additional premise in support of the conclusion.

The correct response to Question 2 is (C). The task in this problem is to find the answer choice that is most strongly supported, that is, the one that is most likely to be true, given that the information stated in the passage is true. (C) is the best response. The only difference cited in the passage between the children who developed nearsightedness and the parents and grandparents who did not have this disability is the fact that the children went to school whereas the parents and grandparents did not. The inference to be drawn from this information is that school activities such as reading that require the use of vision are somehow causally related to the nearsightedness. Admittedly, the information stated in the passage would not, by itself, prove that these activities are the cause of the children's nearsightedness but it would provide strong support for this claim.

(A) is unsupported by the passage. Response (A) is equivalent in meaning to the claim that all nearsighted people have had the opportunity for formal schooling. Admittedly, formal schooling is implicated with nearsightedness in the passage, but the implication is that formal schooling is, in some instances, a significant difference between persons who are nearsighted and persons who are not.

(B) is not strongly supported by the passage. From the information in the passage it can be inferred that there are some people who are illiterate and who also do not suffer from nearsightedness viz., the parents and grandparents of the children. However, it does not follow from this that all people who are illiterate do not suffer from nearsightedness nor is this latter claim strongly supported by this inference.

(D) is unsupported by the passage. Response (D) is equivalent in meaning to the claim that all nearsighted people are literate. While it is implied in the passage that some illiterate people are not nearsighted viz., the parents and grandparents of the nearsighted children, it does not follow from this that all illiterate people are not nearsighted, nor is this claim strongly supported by this.

(E) is unsupported by the passage. The passage states only that "two-thirds of the children developed considerable levels of nearsightedness after starting school." No inference regarding the remaining one-third of the students is warranted.

The correct response to Question 3 is (A). The task in this problem is to find an answer that strengthens the argument; that is, one that offers support for the major assumption of the argument or that provides additional evidence for the conclusion. The argument in the passage can be represented as follows:

Premise: Compared to the five-year period prior to the passage of laws requiring the use of safety seats by children, fatalities of children under age four have decreased by 30 percent.

Conclusion: The passage of laws requiring the use of safety seats by children under age four has resulted in fewer child fatalities over the past five years.

(A) is the best response. The major assumption of the argument is that there are no significant differences between the five-year period preceding the passage of the laws and the five-year period since their passage that could account for the decrease in fatalities. Response (A) supports this assumption.

(B) weakens the argument. The major assumption of the argument is that there are no significant differences between the five-year period preceding the passage of the laws and the five-year period since their passage that could account for the decrease in fatalities. Response (B) undermines this assumption.

(C), (D), and (E) do not offer support for the major assumption of the argument nor do they provide additional evidence for the conclusion of the argument.

The correct response to Question 4 is (B). The task in this problem is to find an answer that weakens the argument; that is, one that undermines the major assumption of the argument, attacks a stated premise, or that suggests an alternative conclusion that could be inferred from the premises. The argument in the passage can be represented as follows:

Premise: Lycopene, glutathione, and glutamine are powerful antioxidants that neutralize the free radicals that are produced in the body as a result of routine bodily processes.

Premise: An excess in your system of the free radicals that are produced in the body as a result of routine bodily processes causes rapid aging.

Conclusion: To slow down aging, it is necessary to supplement your diet with these antioxidants on a daily basis.

(B) is the best response. The major assumption in the argument is that daily ingestion of the antioxidants mentioned in the passage is the only way to rid your system of the free radicals produced as a result of routine bodily processes. Response (B) undermines this assumption.

(A) brings in information not mentioned in the passage. Whether or not persons are concerned with the problem of aging and the time at which that concern is realized are not discussed in the passage.

(C) brings in information not mentioned in the passage. Admittedly, the high cost may prevent some people from using these antioxidants on a daily basis, but the fact that they are beyond the budget of most consumers does not attack a premise of the argument nor does it subvert the major assumption of the argument or suggest an alternative conclusion.

(D) does not undermine the major assumption of the argument, attack a stated premise, or suggest an alternative conclusion that could be inferred from the premises.

(E) brings in information not mentioned in the passage. Additional causes of cellular damage such as smoking are not discussed in the passage.

The correct response to Question 5 is (D). The rhetorical question at the beginning of the passage introduces the issue to be discussed in the argument which is whether it is wrong for doctors to lie about their patients' illness. In the final sentence it is concluded that this practice is wrong because it would be a violation of the good faith contract we enter into when we hire the doctor.

(A) is a premise of the argument.

(B) is unsupported by the passage. The passage does not state that doctors often lie to their patients about their illnesses, nor is this the main focus of the passage. The main focus of the passage is to determine not whether they do, but whether they should engage in this practice.

(C) is a premise of the argument.

(E) is implied by the passage.

I. The company should not be held responsible for failing to correct the control-panel problem that caused the accident. Although the problem had been mentioned earlier in
a safety inspector's report, companies receive hundreds of reports of such problems
and Industry Standard No.42 requires action on these problems only when an accident
is foreseeable.

If the second sentence in the paragraph above is factually correct, the answer to which of the following questions is most relevant in helping to determine whether or not the company violated Industry Standard No.42 when it failed to correct the control-panel problem.
(A) Was the accident serious?

(B) Was the control-panel problem of a type that is known
to indicate that an accident is likely?

(C) Since the accident, has the company done a special safety
check on all control panels?

(D) Did the safety inspector mention more than one problem in
the same report?

(E) How long was the control panel in use before the problem
was discovered?

Ans: B.

II. In a game, exactly six inverted cups stand side by side in a straight line, and each has exactly one ball hidden under it. The cups are numbered consecutively1 through 6. Each of the balls is painted a single solid color. The colors of the balls are green, magenta, orange, purpose, red and yellow.
