Critical Reasoning Butler: August 2026
August 20CR 1CR 2

___________________________
CR 1

­Caffeine is a chemical compound that stimulates the human central nervous system. Research into the effects of caffeine has been performed by a myriad of companies from different places around the world, and new evidence is published every few months. High caffeine intakes cause nervousness and insomnia in some subjects while drowsiness and repose are experienced by others. Furthermore, some people report a laxative effect while in others it can result in constipation.

Which of the following conclusions is most strongly supported by the information above?

(A) Since there is not enough consistency with regards to results, research of such a chemical is not advantageous and should be discontinued.

(B) The individuality of human subjects creates difficulty when attempting to form a definitive judgement about the symptoms of caffeine.

(C) Caffeine does not affect the central nervous system in all people and, therefore, physiological symptoms can also vary.

(D) Caffeine can act as an addictive substance causing unpleasant side effects and harm to the human body's basic functions.

(E) To conduct more accurate research, examinations should be carried out on larger test groups.

___________________________
CR 2

Clearly, the pollution of the beaches is doubly harmful. Not only does the pollution hurt the wildlife inhabiting the stretches of the seashore but also the youth's education towards conservation is hindered by the frequenting of nature resorts which are continuously polluted. Therefore, it is extremely important that the authorities keep the beaches clean.

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

(A) The first is the opinion favored by the argument; the second is an additional piece of evidence which enhances the same conclusion as the former piece of evidence does.

(B) The first is an assumption; the second is a premise which adds information to a previous premise.

(C) The first is a conclusion; the second is an inference based on a previous premise.

(D) The first is a premise; the second is a conclusion based on a previous premise.

(E) The first is the general position of the argument; the second is an additional piece of evidence which stands in apparent contradiction to the previous information.

Critical Reasoning Butler: August 2026
August 21CR 1CR 2

CR 1

­By conducting surveys and monitoring the brainwave patterns of a group of employees who work from 9 am until 5 pm daily in a variety of fields, scientists determined that after the midday break, energy levels dropped although average decreases in activity only measured at 1%. To deal with this phenomenon in an efficient way, many companies began to provide sleeping facilities for sleepy workers who could rest for short periods of time and then return to work refreshed. Although this strategy revealed that a nap of only 25 minutes did seem to be effective at restoring energy and attentiveness, since the actual decrease in measured activity is fairly minor, a number of companies now intend to do away with this technique.

Which of the following, if true, most seriously undermines the logic of the companies' current intentions?

(A) The employees whose brainwave scans indicated an activity decrease of more than 1% after midday were also those who reported that the meals they ate during their breaks sometimes consisted of a meat item.

(B) Brain activity tests of employees who had not napped but who had performed the same number of tasks as those who had, showed these employees made logical connections that were primarily involved in the creation of basic and, in many cases, nonviable solutions.

(C) Through advancements in technology, current brainwave monitors have the potential to measure frequency differences that are very small whereas in the past only major changes in activity were detectable by researchers.

(D) Brainwaves measured before an hour of sleep has been completed are far more similar to those emitted while in an awakened state than to those emitted during sleep associated with significant rest.

(E) Employees who are presented with the option of sleeping at their places of employment are likely to take less heed in being responsible for the amount of sleep they get before arriving to perform a day's work.

CR 2

Unlike in the vast majority of species of monkeys, in a newly discovered society of minuscule monkeys in South Africa the dominant male is not the largest specimen, but rather the one with the strongest odor, even if it is quite unimpressive looking.

Which of the following, if true, would most contribute to an explanation of the facts above?

A. The new type of monkey is deaf.

B. Odor plays a role in the ability to determine ovulation among many mammals.

C. The new species of monkey is visually impaired, and thus relies on its sense of smell.

D. In most monkey communities the largest and strongest males are the alpha males and they mate with the mature females of the community.

E. Monkeys have a wide variety of parameters which together establish order of precedence among the males of a community.
