Each of the following, if true, weakens the conclusion drawn here except:

A There are more shoe stores in Town A.
B Town B only has stores that sell running shoes.
C The average price for the same pair of shoes is less in Town A than in Town B.
D Town A has a larger population than Town B.
E Most citizens of Town B work in Town A and therefore find it more convenient to buy their shoes there.


I found it a little confusing.

Houses built during the last ten years have been found to contain indoor air pollution at levels that are, on average, much higher than the levels found in older houses. The reason air-pollution levels are higher in the newer houses is that many such houses are built near the sites of old waste dumps or where automobile emissions are heavy. Which of the following, if true, calls into question the explanation above?

(A) Many new houses are built with air-filtration systems that remove from the house pollutants that are generated indoors.
(B) The easing of standards for smokestack emissions has led to an increase in air-pollution levels in homes.
(C) New houses built in secluded rural areas are relatively free of air pollutants.
(D) Warm-weather conditions tend to slow down the movement of air, thus keeping pollution trapped near its source.
(E) Pressboard, an inexpensive new plywood substitute now often used in the construction of houses, emits the pollutant formaldehyde into the house. ]]> GMAT Critical Reasoning nverma http://www.urch.com/forums/gmat-critical-reasoning/128889-cr_1-please-explain.html Explain this tricky one!!!! http://www.urch.com/forums/gmat-critical-reasoning/128870-explain-tricky-one.html Tue, 17 Nov 2009 17:20:00 GMT Although its purpose is laudable, the exclusionary rule, which forbids a court to consider evidence seized in violation of the defendant’s constitutional rights, has unduly hampered law-enforcement efforts. Even when the rights violation was a minor or purely technical one, turning on a detail of procedure rather than on the abrogation of some fundamental liberty, and even when it has been clear that the police officers were acting in good faith, the evidence obtained has been considered tainted under this rule and may not even by introduced. In consequence, defendants who were undoubtedly guilty have been set free, perhaps to steal, rape, or murder again.

It can be inferred from the passage that the author would most likely endorse which of the following proposals?
(A) Change of the exclusionary rule to admit evidence obtained by police officers acting in good faith
(B) A constitutional amendment curtailing some of the protections traditionally afforded those accused of a crime
(C) A statute limiting the application of the exclusionary rule to cases involving minor criminal offenses
(D) Change of the exclusionary rule to allow any evidence, no matter how obtained, to be introduced in court
(E) A constitutional amendment allowing police officers to obtain vital evidence by any means necessary when in pursuit of a known criminal

IMO A
Although the question has been discussed before on the forum, I am somehow not convinced that the IMO is correct. Can someone shed some light why B is not the answer. My reasoning is that isnt it inherently assumed that police officers would act in good faith and hence, A cannot be the answer. ]]> GMAT Critical Reasoning junoon http://www.urch.com/forums/gmat-critical-reasoning/128870-explain-tricky-one.html Smithtown University http://www.urch.com/forums/gmat-critical-reasoning/128738-smithtown-university.html Sun, 15 Nov 2009 09:07:51 GMT Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted.

Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted. This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job. On the contrary, since the people most likely to donate are those who have donated in the past, good fundraisers
constantly try less-likely prospects in an effort to expand the donor base. The high success rate shows insufficient canvassing effort.


Which of the following, if true, provides more support for the argument?

A. Smithtown University’s fund-raisers were successful in their contacts with
potential donors who had never given before about as frequently as were fundraisers
for other universities in their contacts with such people.
B. This year the average size of the donations to Smithtown University from new
donors when the university’s fund-raisers had contacted was larger than the
average size of donations from donors who had given to the university before.
C. This year most of the donations that came to Smithtown University from people
who had previously donated to it were made without the university’s fund-raisers
having made any contact with the donors.
D. The majority of the donations that fund-raisers succeeded in getting for
Smithtown University this year were from donors who had never given to the
university before.
E. More than half of the money raised by Smithtown University’s fund-raisers came
from donors who had never previously donated to the university.

Telomerase is an enzyme that is produced only in cells that are actively dividing. For this reason it is generally absent from body tissues in adults. Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing.

The information provided most strongly supports which of the following?
  • Telomerase is the only enzyme that is present in cancerous cells but absent from cells that are not actively dividing.
  • In children, the only body tissues from which telomerase is absent are those in which cells are not rapidly dividing.
  • The presence of telomerase in bone marrow is no indication of bone marrow cancer.
  • Cancer of the bone marrow develops more rapidly than cancer growing in any other kind of adult tissue.
  • The level of telomerase production is always higher in cancerous tissue than in noncancerous tissue.

This is my first post on here so be gentle ;)

I've done a little bit of GMAT prep on and off over the last few years and have almost always been able to reconcile myself to the point of view of the OA. Normally it is quite obvious when you've read the explanations. However in this case, I have looked at it time and again, consulted previous threads on this question, and still can't see why that would be the right answer.

I'd be very interested to engage in some discussion on it.

Here is the question:


Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.

Which of the following, if true, most seriously undermines the advertisement's argument?

(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.
(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.
(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.
(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor's prescription.
(E) In clinical trials Novex has been found to be more effective than competing brands of painkillers that have been on the market longer than Novex.


I'll leave it there for those that want to try to solve and come back with my reasoning and the OA in a bit.

Thanks,

Such ices have a tendency to vaporize, producing an atmosphere. Since the proportion of any gas in such an atmosphere depends directly on how readily the corresponding ice vaporizes, astronomers have concluded that the components of Pluto’s atmosphere are nitrogen, carbon monoxide, and methane, in order of decreasing abundance.
The astronomers’ argument relies on which one of the following assumptions?
(A) There is no more frozen nitrogen on the surface of Pluto than there is either frozen carbon monoxide or methane.
(B) Until space probes reach Pluto, direct analysis of the atmosphere is impossible.
(C) There is no frozen substance on the surface of Pluto that vaporizes more readily than methane but less readily than carbon monoxide.
(D) Nitrogen is found in the atmosphere of a planet only if nitrogen ice is found on the surface of that planet.
(E) A mixture of nitrogen, carbon monoxide, and methane is characteristic of the substances from which the Solar System formed.

Audiences find a speaker more convincing if the speaker begins a speech by arguing briefly against his or her position before providing reasons for accepting it. The reason this technique is so effective is that it makes the speaker appear fair-minded and trustworthy.

Which one of the following, if true, most seriously limits the effectiveness of adopting the argument’s recommendation?
(A) Political candidates typically have no control over which excerpts from their speeches will be reported by the news media.
(B) Many people do not find arguments made by politicians convincing, since the arguments are often one-sided or oversimplify the issues.
(C) People decide which political candidate to vote for more on the basis of their opinions of the candidate’s character than on the exact positions of the candidate.
(D) People regard a political candidate more favorably if they think that the candidate respects an opponent’s position even while disagreeing with it.
(E) Political candidates have to address audiences of many different sizes and at many different locations in the course of a political campaign.
