Questions 19-20 are based on the following.
Blood banks will shortly start to screen all donors for NANB hepatitis. Although the new screening tests are estimated to disqualify up to 5 percent of all prospective blood donors, they will still miss two-thirds of donors carrying NANB hepatitis. Therefore, about 10 percent of actual donors will still supply NANB-contaminated blood.
19. The argument above depends on which of the following assumptions?
(A) Donors carrying NANB hepatitis do not, in a large percentage of cases, carry other infections for which reliable screening tests are routinely performed.
(B) Donors carrying NANB hepatitis do not, in a large percentage of cases, develop the disease themselves at any point.
(C) The estimate of the number of donors who would be disqualified by tests for NANB hepatitis is an underestimate.
(D) The incidence of NANB hepatitis is lower among the potential blood donors than it is in the population at large.
(E) The donors who will still supply NANB-contaminated blood will donate blood at the average frequency for all donors.
20. Which of the following inferences about the conse-quences of instituting the new tests is best supported by the passage above?
(A) The incidence of new cases of NANB hepatitis is likely to go up by 10 percent.
(B) Donations made by patients specifically for their own use are likely to become less frequent.
(C) The demand for blood from blood banks is likely to fluctuate more strongly.
(D) The blood supplies available from blood banks are likely to go down.
(E) The number of prospective first-time donors is likely to go up by 5 percent.
19. assumption:
- that 2/3 people missed will not get rejected by other tests. So without this assumption there will be less than 10% blood donors with NANB.
So A.
20. consequences of new test are:
- reduction (not elimination) in the NANB blood. so few people will NANB in future.
- reduction in blood supplies.
So D.

Questions 3-4 are based on the following
Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, they could forecast the weather with real precision. But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model.
3. Which of the following, if true, could best be used as a basis for arguing against the authors position that the meteorologists claim cannot be evaluated?
(A) Certain unusual configurations of data can serve as the basis for precise weather forecasts even though the exact causal mechanisms are not understood.
(B) Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts.
(C) Mathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.
(D) Modern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time.
(E) Meteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct.
4. Which of the following, if true, would cast the most serious doubt on the meteorologists boast, aside from the doubt expressed in the passage above?
(A) The amount of energy that the Earth receives from the Sun is monitored closely and is known not to be constant.
(B) Volcanic eruptions, the combustion of fossil fuels, and several other processes that also cannot be quantified with any accuracy are known to have a significant and continuing impact on the constitution of the atmosphere.
(C) As current models of the atmosphere are improved, even small increments in complexity will mean large increases in the number of computers required for the representation of the models.
(D) Frequent and accurate data about the atmosphere collected at a large number of points both on and above the ground are a prerequisite for the construction of a good model of the atmosphere.
(E) With existing models of the atmosphere, large scale weather patterns can be predicted with greater accuracy than can relatively local weather patterns.
5.The following proposal to amend the bylaws of an organization was circulated to its members for comment.
When more than one nominee is to be named for an office, prospective nominees must consent to nomination and before giving such consent must be told who the other nominees will be.
Which of the following comments concerning the logic of the proposal is accurate if it cannot be known who the actual nominees are until prospective nominees have given their consent to be nominated?
(A) The proposal would make it possible for each of several nominees for an office to be aware of who all of the other nominees are.
(B) The proposal would widen the choice available to those choosing among the nominees.
(C) If there are several prospective nominees, the proposal would deny the last nominee equal treatment with the first.
(D)The proposal would enable a prospective nominee to withdraw from competition with a specific person without making that withdrawal known.
(E) If there is more than one prospective nominee, the proposal would make it impossible for anyone to become a nominee.
6.Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.
Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:
(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.
(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.
(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.
(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.
(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.
7.Teresa: Manned spaceflight does not have a future, since it cannot compete economically with other means of accomplishing the objectives of spaceflight.
Edward: No mode of human transportation has a better record of reliability: two accidents in twenty-five years. Thus manned spaceflight definitely has a positive future.
Which of the following is the best logical evaluation of Edwards argument as a response to Teresas argument?
(A) It cites evidence that, if true, tends to disprove the evidence cited by Teresa in drawing her conclusion.
(B) It indicates a logical gap in the support that Teresa offers for her conclusion.
(C) It raises a consideration that outweighs the argument Teresa makes.
(D) It does not meet Teresas point because it assumes that there is no serious impediment to transporting people into space, but this was the issue raised by Teresa.
(E) It fails to respond to Teresas argument because it does not address the fundamental issue of whether space activities should have priority over other claims on the national budget.
8. Black Americans are, on the whole, about twice as likely as White Americans to develop high blood pressure. This likelihood also holds for westernized Black Africans when compared to White Africans.
Researchers have hypothesized that this predisposition in westernized Blacks may reflect an interaction between western high-salt diets and genes that adapted to an environmental scarcity of salt.
Which of the following statements about present-day, westernized Black Africans, if true, would most tend to confirm the researchers hypothesis?
(A) The blood pressures of those descended from peoples situated throughout their history in Senegal and Gambia, where salt was always available, are low.
(B) The unusually high salt consumption in certain areas of Africa represents a serious health problem.
(C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.
(D) Blood pressures are low among the Yoruba, who, throughout their history, have been situated far inland from sources of sea salt and far south of Saharan salt mines.
(E) No significant differences in salt metabolism have been found between those people who have had salt available throughout their history and those who have not.

1. background: hamsters with heart disease, variables tested in the research: fluorescent vs darkness, length of exposure.
A. to be able see in fluorescent was not tested
B. answer, coz relation between health and light were tested
C. survival in darkness is not relevant
D. irrelevant
E. blooming (not necessarily health) vs light.
2. so we hv to fill the gap with some issue that consumers would consider before learning about their user-friendliness. from the choices we have cost and needs as the optional choices. so needs>cost>user-frend OR needs>user-frend>cost. the only option with cost is B, which makes both cost and user-fren equal. So needs is the answer So is E.

The government-owned gas company has begun selling stoves and other gas appliances to create a larger market for its gas. Merchants who sell such products complain that the competition will hurt their businesses. That may well be; however, the government-owned gas company is within its rights. After all, the owner of a private gas company might will decide to sell such appliances and surely there would be nothing wrong with that.
Which one of the following principles, if valid, most helps justify the reasoning above?
(A) Government-owned companies have the right to do whatever private businesses have the right to do.
(B) A government should always take seriously the complaints of merchants.
(C) Private businesses have not right to compete with government monopolies.
(D) There is nothing wrong with a government-owned company selling products so long as owners of private companies do not complain.
(E) There is nothing wrong with private companies competing against each other.
Reducing speed limits neither saves lives nor protects the environment. This is
because the more slowly a car is driven, the more time it spends on the road spewing exhaust into the air and running the risk of colliding with other vehicles.
The arguments reasoning is flawed because the argument
(A) neglects the fact that some motorists completely ignore speed limits.
(B) Ignore the possibility of benefits from lowering speed limits other than environmental and safety benefits.
(C) Fails to consider that if speed limits are reduced, increased driving times will increase the number of cars on the road at any given time.
(D) Presumes, without providing justification, that total emissions for a given automobile trip are determined primarily by the amount of time the trip takes
(E) Presumes, without providing justification, that drivers run a significant risk of collision only if they spend a lot of time on the road.
People who do not believe that others distrust them are confident in their own abilities, so people who tend to trust others think of a difficult task as a challenge rather than a threat, since this is precisely how people who are confident in their won abilities regard such tasks.
The conclusion above follows logically if which one of the following is assumed?
(A) People who believe that others distrust them tend to trust others.
(B) Confidence in ones own abilities gives one confidence in the trustworthiness of others.
(C) People who tend to trust others do not believe that others distrust them.
(D) People who are not threatened by difficult tasks tend to find such tasks challenging.
Mullen has proposed to raise taxes on the rich, who made so much money during the past decade. Yet Mullens tax records show heavy investment in business during that time and large profits; so Mullens proposal does not deserve our consideration.
The flawed reasoning in the argument above is most similar to the flawed reasoning in which one of the following?
(A) Do not vote for Smiths proposed legislation to subsidize child care for working parents; Smith is a working parent.
(B) Do not put any credence in Dr. Hans recent proposal to ban smoking in all public places; Dr. Han is a heavy smoker.
(C) The previous witnesss testimony ought to be ignored; he has been convicted of both forgery and mail fraud.
(D) Board member Timms proposal to raise the salaries of the companys middle managers does not deserve to be considered; Timms daughter is a middle manager at the companys headquarters.
(E) Dr. Wasows analysis of the design of this bridge should not be taken seriously; after all, Dr. Wasow has previously only designed factory buildings.
Shy adolescents often devote themselves totally to a hobby to help distract them from the loneliness brought on by their shyness. Sometimes they are able to become friends with others who share their hobby. But if they lose interest in that hobby, their loneliness may be exacerbated. So developing an all-consuming hobby is not a successful strategy for overcoming adolescent loneliness.
Which one of the following assumptions does the argument depend on?
(A) Eventually, shy adolescents are going to want a wider circle of friends than is provided by their hobby.
(B) No successful strategy fro overcoming adolescent loneliness ever intensifies that loneliness.
(C) Shy adolescents will lose interest in their hobbies if they do not make friends through their engagement in those hobbies.
(D) Some other strategy for overcoming adolescent loneliness is generally more successful than is developing an all-consuming hobby.
(E) Shy adolescents devote themselves to hobbies mainly because they want to make friends.

Guys please xplain the above 5 CRs..
1) Author reasons that there is no wrong in government companies selling stoves. We need to support this.
A.Yes if this true then the government company can sell just as a private company would have. (second part says private company can do the same and no one complains).
B.Cannot support
C.Irrelevant doesn't in any way concerned with government companies sales
D.Here the reasoning is based on merchants' complaints.
E.Irrelevant
2) Authors wants to prove speed limit is not necessary. He says driving slow-- results in more time-- and hence collision and doesn't protect environment.
What can be the flaw or the missing link? there is not relationship mentioned between more time spent and more accidents. So E should be the answer. Note:Author says more time spent-- more exhaust so he not provide further justification on environment pollution So D can't be the answer.
3)premise--> people who believe others trust them--- have confidence
conclusion-->people who trust others---- think difficult task as challenge = people with confidence
So there should be something that relates people who believe others trust them and people who trust others to arrive at the conclusion of people who trust others. Only C provides this. I think C is the answer. You have forgotten to type option E
4) Mullen proposes-- increase tax on rich who made profits.
Mullen made huge investments and large profits (Mullen is rich)
A. Mullen's recommendation is not favorable for himself
B. Yes goes with what is stated.
C.Doesn't go with what is stated
D.proposal is not favorable
E.Not parallel with what is stated.
I think answer is B
5)I think the answer is B. The argument states indulging in hobby is not successful because it exacerbates the situation if people fail. So the author has to assume the same is not a case of s successful strategy

hi Shiva, Great answers! I am Kasi Gupta planning to take GMAT in SEP-OCT timing.
I think the answer for 2nd Question is D.
First i like to explain why E is wrong.The Passage states that When Vehicles Spend long time on road-> it emits more gas->inturn vehicles collides beacuse of gas emission.(here the usage of conjunction 'and' is important to notice). But that is not stated as per the answer choice E.
E states that long time on road-> causes collision of vehicles,which is irrelevant for the question asked.
But if you consider the Question D, think of a scenario in which a lot of emission caused by just a single vehicle (something similar to our local Autorickshaws).This scenario states the flaw in the passage which states if vehicles ride long time on road it causes emission.But why not a single polluted vehicle staying short time on road cause the same amount of pollution.
Hope i have given right explanation.
Also the Official answer for the Question is D . It is in LSAT Oct 2002 Section IV question no 14.
Thanks,
Kasi Gupta

Hi KG,
Best of luck in your GMAT.
Agreed with answer D. Would like to add this. The statement says --- more time is spent doing X and Y, here X and Y are parallel actions I don't think conjunction "and" means Y is a result of X. However E can be ruled out because the author says runs a risk. E is about "significant risk" .
1.From 1973 to 1976, total United States consumption of cigarettes increased 3.4 percent, and total sales of chewing tobacco rose 18.0 percent. During the same period, total United States population increased 5.0 percent.

A. United States manufacturers of tobacco products had higher profits in 1976 than in 1973.
B. Per capita consumption of cigarettes in the United States was lower in 1976 than in 1973.
C. The proportion of nonsmokers in the United States population dropped slightly between 1973 and 1976.
D. United States manufacturers of tobacco products realize a lower profit on cigarettes than on chewing tobacco.
E. A large percentage of United States smokers switched from cigarettes to chewing tobacco between 1973 and 1976.
2.When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins. Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.
Which of the following is an assumption on which the argument depends?
A. Renaissance paintings were created in conditions involving far greater fluctuations in temperature and humidity than those permitted by current standards.
B. Under the current standards that museums use when storing Renaissance oil paintings, those paintings do not deteriorate at all.
C. Museum collections typically do not contain items that are more likely to be vulnerable to fluctuations in temperature and humidity than Renaissance oil paintings.
D. None of the materials in Renaissance oil paintings other than the paint are vulnerable enough to relatively wide fluctuations in temperature and humidity to cause damage to the paintings.
E. Most Renaissance oil paintings are stored in museums located in regions near the regions where the paintings were created.

Since it has become known that several of a bank's top executives have been buying shares in their own bank, the bank's depositors, who had been worried by rumors that the bank faced impending financial collapse, have been greatly relieved. They reason that since top executives evidently have faith in the bank's financial soundness, those worrisome rumors must be false. They might well be overoptimistic, however since corporate executives have sometimes bought shares in their own company in a calculated attempt to dispel negative rumors about the company's health.
In the argument given, the two boldfaced portions play which of the following roles?

One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream. Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled "SuperOXY," that has extra oxygen dissolved in the water. Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed bye the muscles is through the lungs.
Which of the following, if true, would serve the same function in the argument as the statement in boldface?
- A. the water lost in exercising can be replaced with ordinary tap water
- B. the amount of oxygen in the blood of people who are exercising is already more than the muscle can absorb
- C. world-class athletes turn in record performance without such water
- D. frequent physical exercise increases the body's ability to take in and use oxygen
- E. lack of oxygen is not the only factor limiting human physical performance
- B. the amount of oxygen in the blood of people who are exercising is already more than the muscle can absorb

- E. lack of oxygen is not the only factor limiting human physical performance
1)
A.No data about cost price and selling price is mentioned so this cannot be the conclusion
B. per capita consumption = (cigarettes consumed/ population). 1973 (X/Y) 1976 (1.034 X / 1.05 Y) so 1973 > 1976. Correct
C. There is no data on number of smokers and non smokers
D. similar to A
E. Out of scope
I think B is the answer
2)Author mentions about oil paintings, temperature and oil paints
A. Irrelevant the paragraph is concerned about storage at present
B. Irrelevant
C. Out of scope other items can be maintained separately
D.Correct. If author expresses his concern only about paints then he should assume other materials in the paintings are not affected
E.Irrelevant
I think D is the answer
For 3 and 4 refer pages 45 and 46 .
I believe its B(OA is wrong here)

Hi,
Please solve this...Found this very tough to understand...
In a nature reserve in India, people are sometimes attacked by tigers. It is believed that the tigers will only attack people from behind. So for the past few years many workers in the reserve have started wearing masks depicting a human face on the back of their heads. While many area residents remain skeptical, no worker wearing one of these masks has yet been attacked by a tiger.
Which of the statements below, if true, would best support the argument of those who advocate the use of the mask?
(A) Many workers in the nature reserve who do not wear the masks have been attacked recently by tigers.
(B) Workers in other nature reserves who wear similar masks have not been
attacked recently by tigers.
(C) No tigers have been spotted on the nature reserve in recent years.
(D) Many of the workers who wear the masks also sing while they work in order to frighten away any tigers in the area.
(E) The tigers have often been observed attacking small deer from in front rather than from behind.
Cheers
