Crowding on Mooreville’s subway frequently leads to delays, because it is difficult for passengers to exit from the trains. Subway ridership is projected to increase by 20 percent over the next 10 years. The Metroville Transit Authority plans to increase the number of daily train trips by only 5 percent over the same period. Officials predict that this increase is sufficient to ensure that the incidence of delays due to crowding does not increase.

Which of the following, if true, provides the strongest grounds for the officials’ prediction?

(A) By changing maintenance schedules, the Transit Authority can achieve the 5 percent increase in train trips without purchasing any new subway cars.

(B) The Transit Authority also plans a 5 percent increase in the number of bus trips on routes that connect to subways.

(C) For most commuters who use the subway system, there is no practical alternative public transportation available.

(D) Most of the projected increase in ridership is expected to occur in off-peak hours when trains are now sparsely used.

(E) The 5 percent increase in the number of train trips can be achieved without an equal increase in Transit Authority operational costs.

can anyone explain why c is incorrect

Q1. At Food World Supermarket, built in 1975, the number of successful thefts has risen dramatically in the last few months. Food world has a reliable electronic security system at all the customer exit doors, and this system is always operational. Therefore the thefts must have been committed by people who used exits other than the regular customer exit doors. Which of the following is assumption that would make the conclusion above logically correct ? (A) If a surveillance system is installed in a supermarket, it is always equipped at every possible exit. (B) If an employee so wishes, he is allowed to leave thorugh an exit that is not monitored by surveillance system. (C) If a store has reliable security system, it is impossible to pass through the system undetected. (D) If a supermarket was built before 1980, it often has exits that cannot be equipped with electtronic surveillance. (E) If a store has a reliable electronic security system but is still experiencing a rise in theft, it must be the case that the employees must are stealing. Difficulty - Hard

Q2. The globalization of trade has been hailed as a positive force for economic growth and development. Proponents argue that increased international trade fosters competition, drives innovation, and allows countries to specialize in their comparative advantages. However, critics contend that globalization exacerbates income inequality, as the benefits of trade are often concentrated in the hands of a few wealthy individuals and corporations, while leaving the majority of the population behind. Which of the following, if true, would weaken the proponents’ argument regarding the positive impact of globalization on global economics? (A) Developing countries that heavily rely on exports are vulnerable to economic downturns in their main trading partners. (B) Global trade agreements often prioritize the interests of powerful nations, disadvantaging smaller economies. (C) Globalization has led to the outsourcing of jobs from developed countries to countries with lower labor costs. (D) International trade has contributed to environmental degradation and unsustainable resource consumption. (E) Studies have shown that the benefits of globalization have disproportionately flowed to multinational corporations rather than local businesses. Difficulty - Hard

CR Questions September - 25 :

Q1. Some doctors believe that a certain drug reduces the duration of episodes of vertigo, claiming that the average duration of vertigo for people who suffer from it has decreased since the drug was introduced. However, during a recent three-month shortage of the drug, there was no significant change in the average duration of vertigo. Thus, we can conclude that the drug has no effect on the duration of vertigo.

Which one of the following is an assumption required by the argument?

(A) If a drug made a difference in the duration of vertigo, a three-month shortage of that drug would have caused a significant change in the average duration of vertigo.

(B) If there were any change in the average duration of vertigo since the introduction of the drug, it would have demonstrated that the drug has an effect on the duration of vertigo.

(C) A period of time greater than three months would not have been better to use in judging whether the drug has an effect on the duration of vertigo.

(D) Changes in diet and smoking habits are not responsible for any change in the average duration of vertigo since the introduction of the drug.

(E) There are various significant factors other than drugs that decrease the duration of vertigo for many people who suffer from it.


Difficulty - Hard

Q2. Sometimes it is advisable for a medical patient to seek a second opinion. But this process can be awkward for both the patient and the physicians, since the patient often worries that the first physician will be alienated. In addition, for the first physician there is the issue of pride: a second opinion tacitly highlights a physician’s fallibility. And the second physician is in the position of evaluating not only a patient’s health, but also, inevitably and uncomfortably, a colleague’s work.

Which one of the following most accurately states the conclusion of the argument as a whole?

(A) Because of the awkwardness involved, it is best for patients not to seek second opinions unless it is absolutely necessary.

(B) In cases in which second opinions are necessary, the first physician often feels that his or her professional judgment is called into question.

(C) The process of obtaining a second medical opinion can be awkward for those involved.

(D) Physicians who are called upon to offer second opinions are always uncomfortable about evaluating the work of colleagues.

(E) In many cases in which medical patients seek second opinions, they are concerned about offending the first physician.

I am kind of confused to choose between option A and C,
But I will end up by choosing option ’C’ (As it somewhat makes sense than option A according to my opinion).

What’s the correct answer in the end? Anyone?
