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. Difficulty - Hard

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. Difficulty - Hard
Q1. A medical journal used a questionnaire survey to determine whether a particular change in its format would increase its readership. Sixty-two percent of those who returned the questionnaire supported that change. On the basis of this outcome, the decision was made to introduce the new format.
Which one of the following, if it were determined to be true, would provide the best evidence that the journal’s decision will have the desired effect?
(A) Of the readers who received questionnires, 90 percent returned them.
(B) Other journals have based format changes on survey results.
(C) The percentage of surveyed readers who like the format change was almost the same as the percentage of the entire potential readership who would like format change.
(D) It was determined that the new format would be less costly than the old format.
(E) Ninety percent of the readers who were dissatisfied with the old format and only 50 percent of the readers who like the old format returned their questionnaires.

Q2. The Rienzi, a passenger ship, sank as a result of a hole in its hull, possibly caused by sabotage. Normally when a holed ship sinks as rapidly as the Rienzi did, water does not enter the ship quickly enough for the ship to be fully flooded when it reaches the ocean floor. Full flooding can be achieved, however, by sabotage. Any ship that sinks deep into the ocean when not fully flooded will implode. Deep-sea photographs of the Rienzi where it rests on the ocean floor, reveal that it did not implode.
Which one of the following must be true on the basis of the information above?
(A) The Rienzi was so constructed as to reduce the risk of sinking by impact.
(B) If the Rienzi became fully flooded, it did so only after it reached the ocean floor.
(C) If the Rienzi was not sunk by sabotage, water flooded into it unusually fast.
(D) If the Rienzi had sunk more slowly it would have imploded.
(E) The Rienzi was so strongly constructed as to resist imploding under deep-sea pressure.
