____________________
CR 1

Critics of strict "promotional gates" at the grade school level point to a recent study comparing students forced to repeat a grade with those promoted despite failing scores on an unscheduled, experimental competency test. Since there was no significant difference between the two groups' scores on a second test administered after completion of the next higher grade level, these critics argue that the retention policy has failed in its expressed purpose of improving students' basic skills.

Which of the following best expresses the argument made by critics of promotional gates?

A. Anxiety over performance on standardized tests often hinders a student s ability to master challenging new material.

B. A student's true intellectual development cannot be gauged by his score on a standardized competency test.

C. The psychological damage a child suffers by repeating a grade outweighs the potential intellectual benefits of a second chance at learning.

D. Strict requirements for promotion do not lead to harder work and greater mastery of fundamentals among students fearful of being held back.

E. Socioeconomic factors as well as test scores influenced whether a given student in the study was promoted or forced to repeat a grade.

____________________
CR 2

In its report for the quarter just ending, Company X announces that in some of its manufacturing processes it plans to begin converting from conventional fuels like oil and natural gas, which are rapidly becoming scarce, to synthetic fuels currently under development in the company's laboratories in Europe and the American far west. Implementation of this plan will almost certainly increase the company's expenses, since even if the synthetic fuels are rendered practical for use they can be expected to cost considerably more than conventional fuels.

Which of the following, if true, casts the most doubt on the argument above?

(A) Company X's synthetic fuels will not be ready for use in its manufacturing processes for at least a decade.

(B) Whatever increased expenses accrue from the development and use of synthetic fuels can and will be passed on to consumers of Company X's products.

(C) Company X's manufacturing processes can be adapted to the use of synthetic fuels at little or no expense.

(D) In time, the raw materials used to produce Company X's synthetic fuels will become as scarce as oil and natural gas.

(E) Long-needed conservation procedures will become practical when synthetic fuels are introduced and will compensate for the higher cost of the fuels.

Two workers, Ava and Ben, are hired to mow a field at a community park. If Ava and Ben work at their respective constant rates, by what percent is the time Ben would take to mow the field alone less than the time Ava would take to mow the field alone?

(1) Ben, working alone at his constant rate, would take 2 hours less to mow the field than Ava, working alone at her constant rate, would take.

(2) Ava and Ben, working simultaneously and independently at their respective constant rates, can mow the field in 3/5 of the time that Ben, working alone at his constant rate, would take to mow the field.

Shareholders and investment analysts have criticized the Vista Products Company for having slow and outdated computer systems in its factories when these systems are compared to Vista's competitor's systems. However, a Vista representative has claimed that such criticism is unfair. The representative noted that Vista spent more money last year per factory upgrading its computer systems than any of its competitors did.

Which of the following, if true, most seriously discredits the reasoning in the company representative's argument?

A. Overall spending per factory on computer systems is lower in Vista Product's industry than in other industries.

B. Vista Products is not as profitable as some of its competitors

C. Companies with fast, modern computer systems would have no need to spend large amounts of money to upgrade these systems.

D. No investment analyst has visited every single Vista Products factory.

E. When assessing the overall quality of a company's operations, production line speed is more critical than the quality of the company's computer systems.

CR 2

Electrical engineers have developed an energy-efficient type of light bulb that can replace the traditional incandescent bulb. The new bulb, known as the electronic lamp, operates by using a high frequency radio signal rather than the filament featured in incandescent bulbs. Although the electronic lamp currently costs 20 times as much as its traditional counterpart, its use will prove more cost effective in the long run. While a 100-watt incandescent bulb lasts 6 months if burned for 4 hours daily, a 25-watt electronic lamp used for the same amount of time each day lasts up to 14 years.

The argument above assumes that

A. the typical household use of a light bulb is approximately 4 hours a day

B. aside from its greater efficiency, the electronic lamp resembles the incandescent light bulb in most aspects

C. the type of light cast by the electronic lamp is different from that cast by an incandescent bulb

D. the price of electronic lamps will decrease as they are produced in increasingly greater quantities

E. a 100-watt incandescent light bulb does not provide significantly more light than a 25-watt electronic lamp

_____________________
CR 1

Journalist: Residents of a natural area popular with tourists have long complained about the air pollution caused by tourists’ use of all-terrain vehicles (ATVs) on local trails. This problem will soon be solved, however, because of a new law requiring that all area tour companies cease using gasoline-powered ATVs and use only electric ones. Whereas a gasoline-powered ATV can emit as much air pollution as multiple cars, electric ATVs produce no emissions.

Which of the following is an assumption on which the journalist’s reasoning relies?

(A) The relatively high weights of electric ATVs do not cause them to cause more damage to local ecosystems than gasoline-powered ATVs.
(B) Few of the residents of the natural area will continue to use gasoline-powered ATVs after the new law goes into effect.
(C) ATVs used on trails do not kick up fine dust that remains airborne for relatively long periods of time.
(D) The vehicles that tourists use to travel to the natural area produce less pollution than the ATVs they ride once there.
(E) The process of mining the minerals used in production of the batteries in electric ATVs does not result in large amounts of air pollution.

_____________________
CR 2

Small Business Owner: Prescott’s grocery store was losing customers because of long checkout lines. To address this issue, Prescott’s installed self-checkout stations so that more customers could check out at a time and the lines would be shorter. This approach will not help Prescott’s retain customers, however, since most of the people who shop at Prescott’s dislike checking out their own groceries.

Which of the following, if true, could a Prescott’s manager use to effectively rebut the argument made by the small business owner?

(A) Prescott’s would not become more profitable if it were to hire more cashiers so that customers could check out quickly without having to check out their own groceries.

(B) Most of Prescott’s customers prefer checking out their own groceries over waiting in long checkout lines.

(C) Before Prescott’s installed the self-checkout stations, there were no times of day when the checkout lines at Prescott’s were generally sufficiently short to satisfy most customers.

(D) Prescott’s biggest spending customers tend also to be those customers least willing to wait in long lines.

(E) Prescott’s has personnel supporting self-checkout who can assist customers with solving any problems they experience while checking out.
