Q1. Naturalist: For several years, coyote have had a robust population throughout the Susquehanna National Forest. Over the past seven years, the Canic Chemical Corporation in nearby Harrisville has been releasing low levels of bromide compounds into the air and groundwater. Some of these compounds, in sufficient concentrations, are suspected of compromising the immune systems of young coyote. A recent study over the entire forest established that 30% of young coyote did not survive their first year of life. Clearly, the bromide compounds released by Canic pose a direct threat to the well-being of coyote in the forest. The answer to which of the following would be most useful for evaluating the naturalist’s reasoning? A) Have significant levels of these bromide compounds been measured in the blood of other mammals in the forest? B) To what parts of the forest does the wind carry the particulate form of these bromide compounds? C) How many of the natural springs in the forest derive from groundwater that flows in the vicinity of Harrisville? D) What naturally available nutrients would strengthen the immune system of young coyote against any effects of these bromide compounds? E) What percentage of healthy coyote survive to adulthood in the wild? Difficulty - Hard

Q2. Almost all arguments against the theory of evolution stem from the fact that it is very difficult to prove how a group of non-living elements can combine together and give rise to life. However, just because something cannot be proved with certainty today doesn’t mean that the possibility isn’t there. Remember, there was a time when almost the whole world believed the Earth was the centre of the universe until Galileo came by and proved otherwise. The statements above, if true, best support which of the following assertions? (A) At one point of time, Galileo was the only person who believed that the earth was not the centre of the universe. (B) A majority of scientists do not agree with the theory of evolution. (C) It is difficult to prove the theory of evolution with certainty. (D) When Galileo stated that the sun and not the earth was the centre of the universe, he was called insane by his compatriots. (E) Everything that, at one time, seems impossible will, at some point in the future, become possible. Difficulty - Hard
CR Questions August - 4 :Q1. According to the results of a new ground-breaking research, those who wake up early in the morning are generally more alert during the day than those who wake up late. Thus, companies should insist that all their employees wake up early so that they remain alert all through the day.
Which of the following is an assumption in the above argument?
(A) People who wake up early in the morning will not get lethargic during the day.
(B) It is a good idea for employees to remain alert during the day.
(C) Alert employees are generally more productive than lethargic ones.
(D) An alert nature does not cause people to wake up early in the morning.
(E) Lethargy can be cured in other ways as well such as by having a cup of strong coffee.

Q2. The report released by the interior ministry states that within the past 5 years the national land-reclamation program has created a 19 percent increase in arable land within the country. If these figures are accurate, the program has been a huge success. Senator Cox, a distinguished mathematician and a woman of brilliance, maintains, however, that the reclamation program could not possibly have been successful. Clearly, therefore, the figures cited in the report cannot be accurate.
The argument above exhibits an erroneous pattern of reasoning most similar to that exhibited by which one of the following?
A) Albert’s father claims that Albert does not know where the spare car keys are hidden. Yesterday however, Albert reported that he had discovered the spare car keys in the garage toolbox, so his father’s claim cannot be true.
B) Gloria’s drama teacher claims that her policy is to give each student the opportunity to act in at least one play during the year but, since Gloria, who attended every class, reports that she was not given such an opportunity the teacher’s claim cannot be true.
C) Amos claims that he can hold his breath under water for a full hour. Dr. Treviso, a cardiopulmonary specialist, has stated that humans are physiologically incapable of holding their breath for even half that long; so Amos’ claim cannot be true.
D) Evelyn reports that she got home before midnight. Robert, who always knows the time, insists that she did not. If Robert is right, Evelyn could not possibly have listened to the late news; since she admits not having listened to the late news, her report cannot be true.
E) Moira, after observing the finish of the 60-kilometer bicycle race, reports that Lee won with Adams a distant third. Lomas, a bicycle engineering expert, insists, however, that Lee could not have won a race in which Adams competed; so Moira’s report cannot be true.
