Q1. Millions of irreplaceable exhibits in natural history museums are currently allowed to decay. Yet without analyses of eggs from museums, the studies linking pesticides with the decline of birds of prey would have been impossible. Therefore, funds must be raised to preserve at least those exhibits that will be most valuable to science in the future. The argument presupposes that (A) if a museum exhibit is irreplaceable, its preservation is of an importance that overrides economic considerations (B) the scientific analysis of museum exhibits can be performed in nondestructive way (C) eggs of extinct species should be analyzed to increase knowledge of genetic relationships among species (D) it can be known at this time what data will be of most use to scientific investigators in the future (E) the decay of organic material in natural history exhibits is natural and cannot be prevented

Q2. Gasoline-powered boat engines manufactured in the a North American country prior to 1990 contribute significantly to the pollution found in the world’s oceans. In 1990, however, the government imposed stricter pollution controls on gasoline engines manufactured for boats, and beginning in 1995, the government imposed a program of inspections for pre-1990 boat engines with increasingly rigorous pollution standards. As the older boat engines fail to pass inspection, boat owners are increasingly retiring their old engines in favor of newer, less polluting boat engines. As a result, the amount of pollution these older boat engines emit into the world’s oceans will steadily decrease over the next ten years. Which one of the following statements, if true, most seriously undermines the argument? (A) Water from the various oceans cannot be accurately divided among nations because ocean currents travel thousands of miles and cross numerous national boundary lines. (B) Even as they become older, boat engines manufactured after 1990 will never pollute as much as boat engines manufactured prior to 1990. (C) When boat owners retire their older boat engines in favor of newer ones, the older engines are frequently sent overseas to countries with less stringent pollution standards, where they are in high demand. (D) The government’s pollution control standards for boat engines are increasingly stricter up until 1998; then they level off. (E) If demand for new fishing and pleasure boats increases significantly every year, then pollution of the world’s oceans will continue to increase, regardless of the fact that older boat engines are being retired.
CR Questions May - 6 :Q1. A famous foreign dictator recently triumphed in a lawsuit against his booking agency, which, after failing to find him at either his palace or his bunker, used a similar-looking impersonator to perform his rendition of a well-known trademark rant for a soft drink commercial. Due to the outcome of that suit, advertisers will stop hiring impersonators for commercials. Thus, ad costs will increase because famous dictators charge more than impersonators do.
This conclusion is flawed because it makes which of the following unwarranted assumptions?
A) Most listeners cannot distinguish whether a speech is being performed by a famous dictator or an impersonator.
B) Ads which use famous dictators are often more effective than those which use impersonators.
C) Some famous speeches’ original versions cannot be licensed for commercial use.
D) Booking agencies will continue using impersonators in place of famous dictators.
E) Advertisers will want to use original speeches.

Q2. In Kantovia, physicians’ income comes from insurance companies, which require physicians to document their decisions in treating patients and to justify deviations from the companies’ treatment guidelines. Ten years ago physicians were allowed more discretion. Most physicians believe that the companies’ requirements now prevent them from spending enough time with patients. Yet the average amount of time a patient spends with a physician during an office visit has actually increased somewhat over the last ten years.
Which of the following, if true, most helps to resolve the apparent discrepancy between physicians’ perceptions and the change in the actual time spent?
A. Patients are more likely to be in a hurry nowadays and are less willing to wait a long time to see their physician.
B. Physicians today typically have a wider range of options in diagnosis and treatment to consider with the patient before prescribing.
C. Physicians are increasingly likely to work in group practices, sharing the responsibility of night and weekend work.
D. Most patients would rather trust their physicians than their insurance companies to make decisions about their treatment.
E. Since the insurance companies pay physicians a set amount for each office visit, it is to physicians’ financial advantage to see as many Patients as possible.
