1. Don’s, a chain of supermarkets, has entered into an agreement in which Rose Computers will sell Don’s an unlimited number of its least expensive PC’s at one-fourth the regular wholesale price. In return, Don’s has agreed to purchase all of its scanners and other electronic information-processing equipment from Rose or from Omicron, Rose Computers’ parent company, for the next ten years. Don’s will offer a Rose PC free to any school that turns in Don’s register receipts totaling $100,000 within the next six months. The vice-president in charge of advertising for Don’s expects that the computer giveaway will obviate the need for a massive new advertising campaign for the next six months and that Don’s can make up the expenditures for the PC’s by writing them off its income taxes as charitable donations.

The plans formulated by Don’s assume each of the following EXCEPT:

(A) The prices that Rose or Omicron charges Don’s for information-processing equipment over the next ten years will be lower than those charged by other companies.

(B) The tax laws will not be changed to exclude or lessen the value of charitable donations as tax write-offs.

(C) Schools will be sufficiently attracted by Don’s computer giveaway offer that teachers will urge students to shop at Don’s.

(D) Rose will be able to supply Don’s with a sufficient number of PC’s to meet the demand generated by schools that collect Don’s receipts totaling $100,000.

(E) The effect of the computer giveaway offer on Don’s business will be comparable to that of a major advertising campaign.

2. Manufacturers of household appliances are still urging the public to purchase food processors. The various manufacturers’ advertisements all point out that the prices of these appliances are now lower than ever and that each food processor comes with a lifetime service warranty. In addition, many manufacturers offer sizable rebates to customers who purchase food processors within a given time period. With these incentives, the advertisements contend, people can hardly afford not to purchase food processors.

Which answer choice is a logically prior issue that the manufacturers’ advertisements fail to address?

(A) Whether the cost of repairs to the food processors over the years will cancel out the savings currently being offered.

(B) Whether potential customers have enough uses for food processors to justify purchasing them.

(C) Whether the heads of the companies manufacturing food processors own food processors themselves.

(D) Whether the food processors currently being advertised will be outdated within the next five years.

(E) Whether accessories and replacement parts will be readily available at retail outlets.

3. Since the invention of digital readout, machine designers have rushed to replace conventional dials and gauges with digital units. Yet the digital gauge has drawbacks in some situations. Since it presents an exact numeric value, it must be decoded and analyzed by a human operator; its meaning cannot be read in an instantaneous scanning. An analog dial or gauge can be marked with red to alert the operator when a value is entering a danger zone; a digital gauge cannot. And it is difficult to tell whether a digital readout is increasing or decreasing over time, while the up or down movement of a pointer on an analog gauge can be quickly and easily observed.

The author of the passage above would probably recommend the use of digital gauge in cases when

I. warning of a sudden rise or fall in value is needed.

II. an operator must read and interpret several gauges within a few seconds.

III. a precise numeric value is essential.

(A) I only.

(B) III only.

(C) I and III only.

(D) II and III only.

(E) I, II, and III.

4. Psychologists conducted a series of experiments to test the effect upon schoolchildren of violence in films. In the first experiment, grammar school children were shown a film that included scenes of a male teenager engaging in violent acts against others, such as punching, pushing, and kicking. During a free-play session following the film viewing, 42 percent of the children were observed to engage in one or more violent acts similar to those in the film. In a second experiment, a different group of children was shown a similar film featuring a female teenager. Only 14 percent of the children were observed behaving violently afterward. The psychologists concluded that children are more likely to imitate violent behavior on film when a male model is shown than when a female model is shown.

Which of the following, if true, would most seriously weaken the psychologists’ conclusion?

(A) In both experiments, the victims of the filmed violence included both males and females.

(B) In the second experiment, 28 percent of the children appeared upset during the viewing the violent film scenes.

(C) The first group included 19 male students and 20 female students; the second group included 20 male students and 21 female students.

(D) In the first group, 58 percent of the children appeared bored during the showing of the film, and 12 percent fell asleep.

(E) The percentage of children known to have discipline problems prior to the experiment was greater in the first group than in the second group.
