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.
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.
Argument:
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.
Proposal:
all visitors from Country Y must submit to a medical examination before entering Country X
Ques:
Prove that the proposal is worthless/useless..
If I can prove that medical exams whether +ve or -ve are not going to help curb TB in country X then I am good.. that can simply be done by proving that human's are not carrier of the disease..
I would have marked option D
d. Tuberculosis is not spread through human contact.

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. - Insuff data to take this as useful, so NA
b. Current medical technology is not capable of detecting all carriers of tuberculosis. - close one, but too vague.. not supported anywhere..
c. Country X does not have the resources to examine all visitors from Country Y. - this situation can be handled easily.. only if needed.. so not suff
d. Tuberculosis is not spread through human contact.
- BEST OPTION.. Humans are not the carriers for this disease
e. Citizens of Country Y will not travel to Country X if the proposal is implemented. - this will actually strengthen the proposal
Varun,
Isn't there a difference between saying tb is not spread through human contact and humans are not carriers of the disease? I think there is. As long as a human has the disease causing microorganism, he is a carrier.
If my argument is right then in choosing option D, you must assume that human contact is the only way tb can spread.
Correct me if I am wrong.

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 company's 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.
A number of charges have been raised against me, some serious, some trivial. Individuals seeking to control the corporation for their own purposes have demanded my resignation. Remember that no court of law in any state has found me guilty of any criminal offense whatsoever. In the American tradition, as you know, an individual is considered innocent until proven guilty. Furthermore, as the corporations unbroken six-year record of growth will show, my conduct of my official duties as chairman has only helped enhance the success of the corporation, and so benefited every stockholder.
Which of the following can be properly inferred from the excerpt?
(A) The chairman believes that all those who have demanded his resignation are motivated by desire to control the corporation for their own purposes.
(B) Any misdeeds that the chairman may have committed were motivated by his desire to enhance the success of the corporation.
(C) The chairman is innocent of any criminal offense.
(D) The corporation has expanded steadily over the past six years.
(E) Any legal proceedings against the chairman have resulted in his acquittal.
2. As an experienced labor organizer and the former head of one of the nations most powerful labor unions, Grayson is an excellent choice to chair the new council on business-labor relations.
Which of the following, if true, would most strengthen the conclusion above?
(A) The new council must have the support of the nations labor leaders if it is to succeed.
(B) During his years as a labor leader, Grayson established a record of good relations with business leaders.
(C) The chair of the new council must be a person who can communicate directly with the leaders of the nations largest labor unions.
(D) Most of the other members of the new council will be representatives of business management interests.
(E) An understanding of the needs and problems of labor is the only qualification necessary for the job of chairing the new council.
3. Its time we stopped searching for new statistics to suggest that we are not spending enough on education. In fact, education spending increased 30 percent overall during the last decade.
Which of the following, if true, would most weaken the argument above?
(A) Despite increased spending on education, enrollment in our elementary and secondary schools declined about 4 percent during the last ten years.
(B) Our spending on gasoline increased more than 100 percent during the last decade.
(C) When adjusted for inflation, our per-pupil expenditure on education this year is less than it was ten years ago.
(D) Eleven other economically developed nations spend more on education than we do.
(E) The achievement levels of our students have been declining steadily since 1960, and the last decade produced no reversal in this trend.

A. There is a considerable degree of variation in shade of color between weeds of different species. not relevent.. we are looking for shade between plant and weed.. this option misguides.
B. The shade of color of some plants tends to change appreciably over the course of their growing season.not relevent.. we are looking for shade between plant and weed.. this option misguides.
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds. Confusing statement.. nothing to deduce...
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.Correct answer.. If this statement were true, even if the plant and weed have same color,we can modify plant to have a different color and can enable the use of prototype.
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.- Wrong
D should be the answer.

Mayor Delmonts critics complain about the jobs that were lost in the city under Delmonts leadership. Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office. So there can be no question that throughout Delmonts tenure the average paycheck in this city has been getting steadily bigger.
Which of the following, if true, most strengthens the argument in the advertisement?
A. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmonts tenure.
B. Average pay in the city was at a ten-year low when Mayor Delmont took office.
C. Some of the jobs created in the city during Mayor Delmonts tenure have in the meantime been eliminated again.
D. The average pay for jobs eliminated in the city during Mayor Delmonts tenure has been roughly equal every year to the average pay for jobs citywide.
E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.
Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.
Which of the following, if true, provides the most support for the scientists hypothesis?
A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it.
B. The two chemicals that repel mosquitoes also repel several other varieties of insects.
C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.
D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies.
E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.
Which of the following most logically completes the argument below?

Lets talk about the first one.
This is most wierd question that i have seen till now...Thanks for posting it.
My Strategy: To strengthen the conclusion :throughout Delmonts tenure the average paycheck in this city has been getting steadily bigger. we need to support the premise.
We need to find something which will weak the opening statement :Mayor Delmonts critics complain about the jobs that were lost in the city under Delmonts leadership.
Look at answer Options now :
A. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmonts tenure.- This talks about paychecks and not about jobs created
B. Average pay in the city was at a ten-year low when Mayor Delmont took office- Same as one
C. Some of the jobs created in the city during Mayor Delmonts tenure have in the meantime been eliminated again-- No of jobs created= no of jobs lost. This clearly tells us critics are wrong.
D. The average pay for jobs eliminated in the city during Mayor Delmonts tenure has been roughly equal every year to the average pay for jobs citywide.-same as one
E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.-same as one

I don't think so!!!!
You are trying to weaken another premise, which seemingly contradicts the argument and hence proving that the, it supports the conclusion.
Indeed conclusion is outright different to both of them, It says throughout Delmonts tenure the average paycheck in this city has been getting steadily bigger, Now what it has got to do with C

Which of the following is a consideration in favor of the companys implementing its

A. There is a considerable degree of variation in shade of color between weeds of different species. - weakens
B. The shade of color of some plants tends to change appreciably over the course of their growing season. - weakens
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds. - out of scope
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. - strengthens though doesnt say anything about lowering labour costs
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. - strengthens and mentions laborer can't be put to other duties if weeding task is offloaded
D/E strengthens
My take is E

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
