GMAT Critical Reasoning Discussions

1) At present Satellex Radio provides only music stations. However, many Satellex subscribers listen to talk radio stations as well, and they would prefer that Satellex offered talk radio as well. Moreover, subscribers to radio services that provide talk radio usually subscribe for longer periods of time than those who subscribe to music-only services. Therefore, if Satellex added talk radio stations, its profits would increase.

The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that

(A) Satellex�'s large subscriber base would appeal to talk radio hosts, making it easy for Satellex to hire quality talent for its talk radio stations.
(B) Most talk radio hosts broadcast on advertiser-supported radio stations that listeners can access without paying a subscription fee.
(C) Satellex�'s costs would rise by adding several talk-radio stations, while many of the listeners who want talk radio are already Satellex subscribers.
(D) Talk radio listeners generally spend more time on a single radio station than do listeners to music radio.
(E) If Satellex added talk radio stations, many of Satellex�'s music radio hosts would switch to talk-radio stations, making the music stations less appealing.



2) Zuksha International Airport was once the busiest airport in the region, but two major airlines have relocated to nearby airports, reducing the number of flights in and out of Zuksha by more than half. The gates at Zuksha were built more than thirty years ago and cannot accommodate the largest modern aircraft. In an effort to bring in more business, Zuksha officials plan to build dozens of gates to accommodate modern aircraft and offer reduced-rate leases to airlines willing to make long-term commitments.

Which of the following, if true, most threatens the plan�'s likelihood of success?

(A) Most of the airlines operating out of nearby airports have long-term leases on gates at the other airports.
(B) The existing gates at Zuksha rent at rates that are, on average, much lower than the proposed rates for the new gates to be built there.
(C) Because of highway congestion and changing development patterns that make Zuksha inconvenient to access, airline customers prefer to depart from other airports.
(D) Of the 18 airlines that serve Zuksha or nearby airports, none serve more than one airport in the area.
(E) If the proposed addition is completed, Zuksha will be the largest airport, as measured both by gates and square footage, in the region.


option B and C
A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora's extinction.

Which of the following, if true, most seriously weakens the argument above?

(E) The ibora generally grows in largely inaccessible places.

OAs are in bold!!!


i guess OA is D in this case plz confirm 😃
cognizant_81 Says
this questions has been thoroughly discussed with kaplan mentors and E definetily weakens since the areas where trees are grown are inaccessible so definetly the depletion of the trees cant be easily depleted.


i am not sure about Kaplan, but same question is in OG12 (question number 23, its answer is D in official guide 12th edition)

A drug that is highly effective in treating many types of in € Manhattan GMAT Forums

Manhattan staff has said it is D. and I agree.

Inaccessibility would not stop extinction of trees; it would delay the extinction. However if trees are cultivated they would never be extinct, as said in D
ouses that are located near the beach tend to rise in value, because they often have excellent views of the ocean. However, they may not be a good investment, because they are also particularly susceptible to natural disasters.

And such is the way of all superstitions; wherein humans, having a delight in such vanities, mark the events where they are fulfilled, but where they fail, though this happens much oftener, neglect and pass them by.

Which one of the following contains the error of reasoning described by the author in the passage?

(A) I have discovered that Friday the 13th really is a day of misfortune. Just this past Friday, the 13th, I locked myself out of the house.
(B) Although Napoleon and Alexander the Great were short, Abraham Lincoln and Charles de Gaulle were tall. So short people seek leadership in order to overcome feelings of inferiority.
(C) Every semester for the past 15 years, an average of 10 percent of Ms. Elliot's history students have dropped her course before the exam. So, it seems likely that we can expect 10 percent to drop out this year.
(D) No reliable observer has ever actually seen a yeti. The strongest evidence seems to be some suspicious tracks. So I think this search for a yeti is probably a wild-goose chase.

Spokesperson: The major school lunch vendors recently agreed to stop selling high-calorie beverages in elementary and middle schools because studies show that children of ages 7 to 8 who substitute one low-calorie beverage for one high-calorie soft drink in their daily diets will, on average, weigh 20 pounds less than they would have by the time they reach high school. Since only low-calorie beverages will be sold in schools, within six to eight years, we can expect to see a reduction in the percentage of overweight high-school children.

The spokesperson assumes which of the following to be true?
A All low-calorie beverages are better for children than any high-calorie beverages.
B Elementary and middle school students who used to buy high-calorie soft drinks at school will not bring them to school or drink extra high-calorie beverages at home as a substitute.
C The companies will resume selling high-calorie beverages to schools in eight years.
D Those children whose parents are concerned about healthy weight maintenance already limit their children's consumption of soft drinks.
E Many schools depend on the extra revenue generated by sales of high-calorie drinks

A government issues a travel warning suggesting that travelers avoid visiting a foreign country for their own safety because the country is on the verge of a military coup. The day after the warning, sales of airline tickets to the foreign country increase by four hundred percent.

A
Many tourists are concerned for their safety while traveling.
B
Many journalists and media companies felt compelled to install a bureau in the country during the coup.
C
The military of the country has a general policy to avoid harming foreign tourists.
D
The military coup would cause a wave of refugees wanting to fly out of the country.
E
Ticket sales to the foreign country were relatively weak before the travel warning.

Manufacturers issue cents-off coupons to get consumers to try their brand of product with the hope that the consumers who try their brand will switch their brand loyalty. So in the initial marketing of their new brand X, Hartman Industries should issue cents-off coupons, thereby attracting a large segment of potential consumers as loyal customers.

Which of the following, if true, casts the most serious doubt on the likelihood that the marketing strategy recommended above will have the result that is claimed?

(A) Many consumers are unlikely to try new brands of products unless offered an inducement to do so.
(B) The consumers whose purchases are strongly influenced by cents-off coupons tend not to become loyal customers of any particular brand.
(C) Many grocery stores attract customers by doubling the face value of manufacturer's coupons.
(D) Typically less than one-third of the coupons issued by a manufacturer are redeemed by consumers.
(E) A marketing campaign that uses cents-off coupons is most effective when combined with a television advertising campaign

i will go with B because it explains both sides of the situation, that is even though common civilians/tourists are advised against traveling to the country; YET flights TO that country are overflowing. Explanation could be that of journalists traveling to cover the coup in that country.

A Many tourists are concerned for their safety while traveling.

This choice would not help in resolving contradiction, it further strengthens it


B Many journalists and media companies felt compelled to install a bureau in the country during the coup.

Correct - resolves contradiction

C The military of the country has a general policy to avoid harming foreign tourists.

This would explain no drop in ticket sales to that country but why would ticket sales jump stupendously by 400%?!

D The military coup would cause a wave of refugees wanting to fly out of the country.

That may explain ticket sales of flights OUT OF that country not IN TO the country, it adds no value in our task of resolving contradiction

E Ticket sales to the foreign country were relatively weak before the travel warning.
Ok? So what? This is general observation. Perhaps true. But it doesn't help in explaining why ticket sales jumped by 400% when government advised against traveling to that country.

Of course congnizant_81 has not posted the "stem" but apparent nature of the "stimulus" indicates its resolve the paradox type of question, and answer B stands out for above reasons

Hello,
I am posting one of the classic critical reasoning problem:
try solving this and know/learn the explanation of the same well.

once you understand such a problem I am sure most of your CR fear is out.

try this:

Option (C) seems to be correct.

Pls provide the solution for this alongwith the thinking approach.

Guidebook writer: i have visited hotels throughout the country and have noticed that in those built before 1930, the quality of the original carpentry work is generally superior to the hotels built afterward. Clearly, carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following if true, most seriously weakens the guidebook writer's argument?

(a) the quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.

(b) Hotels built since 1930 can generally accommodate more guests than those built before 1930

(c) The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930

(d) The better the quality of carpentry in a building, less likely the building is to fall into disuse and be demolished

(e) The average length of apprenticeship for carpenters has declined significantly since 1930

I can give u the source if u want...not satisfied with the solution....:splat:

According to me the answer is (b) as it is the closest to refute the Author's argument that quality of workmanship is bcoz of more effort on carpenter's part. Whereas this option gives other reason that since more guests are to be accomodated less attention is paid on details, design & more on the size. Also the more the guests the more the wear & tear of the carpentary

I feel ur assuming too much...!!!!

Anyways...that is nt the right answer

Ok i referred to the soln. And as per my understanding this option proves that since the hotels that have survived till now are because of good carpentry. Hence all the older hotels ought to have good carpentry. All the bad ones wd hav been demolished. Hence comparision is not valid since comparison is being made with the best survived hotels before 1930 to all the hotels (with good as well as bad carpentry) after 1930

Don't have too much idea about it you can go for other forums also to get the more information or you can get by googleit,,
