Critical Reasoning - требует понимания языка и знания математики. Задания заключаются в том, чтобы проанализировать ситуацию, на которой базируется вопрос, и выбрать наиболее подходящий ответ. Каких-либо специальных знаний (например, терминологии) не требуется.

1.A company is considering changing its policy concerning daily working hours. Currently, this company requires all employees to arrive at work at 8 a.m. The proposed policy would permit each employee to decide when to arrive—from as early as 6 a.m. to as late as 11 a.m.

The adoption of this policy would be most likely to decrease employees’ productivity if the employees’ job functions required them to
 (A) work without interruption from other employees
 (B) consult at least once a day with employees from other companies
 (C) submit their work for a supervisor’s eventual approval
 (D) interact frequently with each other throughout the entire workday
 (E) undertake projects that take several days to complete

5. Mayor: In each of the past five years, the city has cut school funding and each time school officials complained that the cuts would force them to reduce expenditures for essential services. But each time, only expenditures for nonessential services were actually reduced. So school officials can implement further cuts  without reducing any expenditures for essential services.
 
  Which of the following, if true, most strongly supports the mayor’s conclusion?
  (A) The city’s schools have always provided essential services as efficiently as they have provided nonessential services.
  (B) Sufficient funds are currently available to allow the city’s schools to provide some nonessential    services.
  (C) Price estimates quoted to the city’s schools for the provision of nonessential services have not increased substantially since the most recent school funding cut.
  (D) Few influential city administrators support the funding of costly nonessential services in the city’s schools.
   (E) The city’s school officials rarely exaggerate the potential impact of threatened funding cuts.

2. The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would have just the same sort of drawback, since things would fall off the shelves’ edges into the rear corners.

   Which of the following is presupposed in the argument against introducing rotating shelves?
    (A) Refrigerators would not be made so that their interior space is cylindrical.
   (B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.
   (C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.
   (D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.
   (E) Rotating shelves would be designed to rotate only while the refrigerator door was open.

4. Two experimental garden plots were each planted with the same number of tomato plants. Magnesium salts were added to the first plot but not to the second. The first plot produced 20 pounds of tomatoes and the second plot produced 10 pounds. Since nothing else but water was added to either plot, the higher yields in the first plot must have been due to the magnesium salts.

  Which of the following, if true, most seriously weakens the argument above?
   (A) A small amount of the magnesium salts from the first plot leached into the second plot.
  (B) Tomato plants in a third experimental plot, to which a high-nitrogen fertilizer was added, but no magnesium salts, produced 15 pounds of tomatoes.
  (C) Four different types of tomatoes were grown in equal proportions in each of the plots.
  (D) Some weeds that compete with tomatoes cannot tolerate high amounts of magnesium salts in the soil.
  (E) The two experimental plots differed from each other with respect to soil texture and exposure to sunlight.
