OA is E. Thanks for your attempts and explanations!
City Controller: 63% of our residents voted to approve the developer's request to build a national chain hotel on the site of the old consignment store. The hotel will increase our revenue base and, therefore, provide more money for schools and community services.
Mayor: But our recent survey showed that the most important reason people want to live here is our small-town feel resulting from the local ownership of the vast majority of businesses.
What is the best explanation for the apparent contradiction in opinions cited by the controller and the mayor? a. Most people believe having a small-town feel is more important than having quality schools. b. A locally-owned business might be able to generate as much revenue as a well-known hotel chain. c. The recent survey did not ask about preferences for a chain hotel versus a locally-owned bed and breakfast. d. An increase in the town's revenue base may not result in additional money for the schools. e. The recent survey cited by the mayor polled people who are considering moving to the town.
OA is D . Tuberculosis is not spread through human contact.
Plz do explain ur reasoning because I am not convinced with the OA.
The number of new cases of tuberculosis diagnosed in Country X increased dramatically this year. The country's news media have speculated that the sharp increase in new cases is the result of the tuberculosis outbreak that occurred in neighboring Country Y last year. Health officials in Country X have therefore proposed that all visitors from Country Y must submit to a medical examination before entering Country X.
Which of the following, if true, most strongly suggests that the proposed medical examinations will NOT help curb the spread of tuberculosis in Country X? a. Country Z, which also neighbors Country Y, has not experienced an increase in cases of tuberculosis. b. Current medical technology is not capable of detecting all carriers of tuberculosis. c. Country X does not have the resources to examine all visitors from Country Y. d. Tuberculosis is not spread through human contact. e. Citizens of Country Y will not travel to Country X if the proposal is implemented.
D and E are quite close but here the stress of the argument is that costs can be reduced by impementing new machine.
D: Selection and genetic manipulation can themselves have a cost involved. E. Laborers are capable of doing other work than weeding. If machines is used, these laborers can leveraged for other duties and thus they dont become an overhead. Hence the ans.
share explanations.. since I know the answer ;)
A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.
Which of the following is a consideration in favor of the companys implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between weeds of different species. B. The shade of color of some plants tends to change appreciably over the course of their growing season. C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds. D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics. E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

My Pick is D..
Plan is based on the fact that weed could be distingusihed from the plant, So anything, which oppose the possibility that "lest plant should not also cut down my equipment while weeding" will support the argument..
D picks it outrightly by stating that every plant can be distinguished by varrying some factors
Hello guys , Sorry for barging into GMAT territory but i thought this would yield a better response here, since the CR thread for CAT is not very active, I wanted to know how good the book ' Critical Reasoning and RC for GMAT' by Manhattan, Can somebody suggest if this book is good enough for CAT since CR questions are not so prominent in CAT. It would also help if you would suggest some other books/ resources
1.In the course of her researches, a historian recently found two documents mentioning the same person, Erich Schnitzler. One, dated May 3, 1739, is a record of Schnitzler's arrest for peddling without a license. The second, undated, is a statement by Schnitzler asserting that he has been peddling off and on for 20 years.
The facts above best support which of the following conclusions?
(A) Schnitzler started peddling around 1719. (B) Schnitzler was arrested repeatedly for peddling. (C) The undated document was written before 1765. (D) The arrest record was written after the undated document. (E) The arrest record provides better evidence that Schnitzler peddled than does the undated document.
2.The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days-the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape's salespeople claim that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.
Which of the following statements, if true, would most seriously call into question the claim made by Newtape's salespeople?
(A) Most surgical wounds take about ten days to heal. (B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons. (C) The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten days. (D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned. (E) Newtape's adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape's adhesion to such coated skin.
3.Advertisement: The world's best coffee beans come from Colombia. The more Colombian beans in a blend of coffee, the better the blend, and no company purchases more Colombian beans than Kreemo Coffee, Inc. So it only stands to reason that if you buy a can of Kreemo's coffee, you're buying the best blended coffee available today.
The reasoning of the argument in the advertisement is flawed because it overlooks the possibility that
(A) the equipment used by Kreemo to blend and package its coffee is no different from that used by most other coffee producers (B) not all of Kreemo's competitors use Colombian coffee beans in the blends of coffee they sell (C) Kreemo sells more coffee than does any other company (D) Kreemo's coffee is the most expensive blended coffee available today (E) the best unblended coffee is better than the best blended coffee
4.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 more effective than competing brands of painkillers that have been on the market longer than Novex.

I guess, its easy one...(Hope havenot overloooked something)
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 bodys ability to take in and use oxygen E. lack of oxygen is not the only factor limiting human physical performance
Argument depends on the fact that Kreemo's purchases max Colmb coffee. One of the reason for this could be that they sell the most coffee. Which raises the possibility that they dont add more colmb coffee to their products.
