CR 1

A common contention among economists is that if they could build an accurate mathematical model that accounted for all economic variables, they could effectively foretell the results of any economic action. But this meaningless conjecture cannot be evaluated because any inadequate predictions would obviously be blamed on imperfections in the model.

Which of the following, if true, would cast the most serious doubt on the economists’ conjecture?

A. The monetary supply produced and maintained by nations across the world is carefully observed and known to be inconsistent.
B. With existing economic models, large scale economic shifts can be predicted with greater accuracy than can relatively local changes in the economy.
C. As existing economic models improve, even small increments in complexity will require large increases in the number of computers required to implement the improved models.
D. Frequent, precise data regarding the decisions of governments and major corporations, as well as accurate predictions regarding upcoming climactic changes, are a prerequisite for constructing an accurate economic model.
E. Irrational human behavior, unexpected natural disasters, and several other processes that also cannot be quantified accurately are known to significantly and continuously affect the economy.

CR 2

Research shows that experimental stem cell procedures designed to repair organ damage primarily affect the integrity of the organ tissue rather than the growth of individual cells within the tissue. Therefore, analyzing the effects of such treatments on the health of the individual cells is irrelevant. Rather, the effectiveness of these treatments should only be assessed at the tissue level.

Which of the following would it be most useful to establish in order to evaluate the argument?

A. Whether two methods to measure the integrity of the treated tissue usually give similar judgment
B. Whether the health of individual cells can be effectively analyzed without introducing factors that may impact cell health positively or negatively
C. Whether the health of individual cells affects the integrity of organ tissue
D. Whether some organs can repair comparable levels of damage without the treatment
E. Whether the research has shown that the stem cell procedure effective in treating one organ can repair damage to another organ

Hi nidhimishragc,

605 would probably be seen as an average or slightly below average score at NUS (average ~615). For Bocconi it'd be better to go in with at least 645-655. However, depending on your profile, you could go ahead with your applications.

All the best.

CR 1

Salmon meat is frequently used in gourmet cooking and retails at high prices. Meat from less valuable white fish, however, can be dyed to give it salmon’s distinct red/pink hue. Only experienced chefs are able to distinguish between genuine salmon and counterfeit salmon prepared in this manner. However, only ten percent of white fish caught can be dyed and much of the meat from these fish is not of a high enough quality for making the treatment worthwhile. Thus, surely the vast majority of salmon sold is genuine.

A serious flaw in the reasoning of the argument is that

A. comparisons between the price of salmon sold for gourmet cooking and its value for personal consumption are not mentioned
B. it does not consider the difficulty that a chef would have in distinguishing between genuine salmon and dyed white fish
C. the possibility that white fish may be used in gourmet cooking, even if it has not been dyed is overlooked
D. it treats the currently available method of dying white fish to resemble salmon as if it were the only method that can be used to do so
E. it does not consider how rare white fish dyed red/pink is in comparison with how rare genuine salmon is

CR 2

The participants sorted into the experimental group of a consumer focus test were instructed to use a new brand of degreasing agent to clean their car engines for a month. Afterward, the members of this group reported a drop in their cars’ acceleration speed, while the control group, those who did not use the degreasing agent, did not report any drop. The detrimental effects on the cars were attributed to a petroleum solvent that is the principal active ingredient in the degreasing agent.

Which of the following, if true, would best help explain how the degreasing agent might produce the observed effect?

A. Chemical analysis of the degreasing agent determined that a concentrated form of the agent was used.
B. Subjects in the focus group did not know whether they were cleaning their car engines with the new degreasing agent or some other substance that is harmless.
C. As the primary use of the degreasing agent is as a cleaning agent, its negative effects are rarely noticed by car owners.
D. The petroleum solvent that is a constituent of the degreasing agent is also sold separately as a heavy-duty industrial cleaner.
E. A high level of the petroleum solvent degrades engine components responsible for the acceleration process.

CR 1

In an interview to a business daily, a senior manager at Windsor Hotels recently stated that the hotel is poorly managed, mentioning the hotel’s inability to modify its marketing strategy in response to a recent surge in its number of unoccupied rooms. A senior manager’s negative comments are generally detrimental to the image of the company, but in this case, the negative comments were also unjustified. Although an increased number of unoccupied rooms at a hotel often indicates that the hotel is losing clients to competitors, in Windsor Hotels’ situation, it does not. Rather, the increase in the number of unoccupied rooms can be attributed entirely to the cancellation, earlier this year, of two of the city’s biggest events.

In the argument given, the two boldfaced portions play which of the following roles?

(A) The first states the position opposed by the argument as a whole; the second states the conclusion of the argument as a whole.
(B) The first states the position opposed by the argument as a whole; the second provides evidence to undercut the support for the position being opposed.
(C) The first states the position opposed by the argument as a whole; the second is evidence that has been used to support the position being opposed.
(D) The first is evidence that has been used to support a position opposed by the argument as a whole; the second provides information to undercut the force of that evidence.
(E) The first is evidence that has been used to support a position opposed by the argument as a whole; the second states the conclusion of the argument as a whole.

To compete with a number of newer restaurants, Rick’s Café has begun offering a free appetizer to every customer who orders more than $40 worth of food. The manager of Rick’s Café claims that the offer has been a huge success in increasing sales, since the number of customers whose orders exceed $40 has increased by twenty-seven percent since the offer began.

Which of the following, if true, most seriously weakens the claim of the manager?

A. Most people who began eating at Rick’s Café after the offer began spending more than $40 each time they eat there.
B. Most people who typically spend less than $25 on a restaurant meal would not be persuaded to spend more by any offer.
C. Nearly all who have begun spending $40 or more at Rick’s Café since the offer began are regular patrons who have increased the average amount spent during one meal at Rick’s Café, but have begun visiting less frequently.
D. Since the offer began, most of the people who spend $40 or more at Rick’s Café are people who have never eaten there before and who always spend more than $40 when eating at restaurants.
E. Most people who received a free appetizer through the offer will continue to eat at Rick’s Café after the offer ends.
