CR 1

Herbed Wellness, a manufacturer of herbal products, wants its new headache remedy to be as effective as possible while using only natural ingredients. A controlled study has found that 58 percent of headache sufferers obtain complete headache relief from a dose of caffeine equivalent to that typically found in a cup of coffee. Therefore, even though the vast majority of its customers are health-conscious avoiders of coffee, Herbed Wellness should add caffeine to its new herbal headache treatment; doing so will prove both efficacious and cost-effective.

The answer to which of the following questions would be most useful in evaluating the claim that caffeine will be efficacious in relieving headaches among Herbed Wellness customers?

A. Is the headache relief provided by caffeine as long-lasting as that provided by over-the-counter drugs such as aspirin?

B. What percentage of the study participants were regular coffee drinkers who suffer from caffeine-withdrawal headaches?

C. Is caffeine less expensive per dose than the individual herbs used in the headache formulation?

D. Does synthetic caffeine qualify as a natural substance?

E. What percentage of Herbed Wellness customers will shun the new headache remedy if it contains caffeine?

In order to reduce classroom overcrowding while maintaining academic standards, Omega High School last year tested an online physics course with twenty volunteers from the senior class. Although they met with the teacher once a week for lab work, the students attended all lectures and did all their homework via remote computer. All of the students in the online physics course easily passed the statewide physics exam at the end of the school year. Administrators at the high school concluded from this test that all students can learn effectively outside the classroom and decided that Omega High School should offer all of its science courses online.

Which of the following, if true, would cast the most doubt on the conclusion drawn above?

A. The science classrooms currently in use are bigger than the classrooms used for other subjects.

B. The students who took the online physics course had access to the same science library reference materials as the physics students who did not take the class online.

C. Omega High School has received a grant to purchase new computers for the next school year.

D. The students who enrolled in the online physics course were more self-motivated than most students and were high achievers in the top ten percentile of their class.

E. There are excellent computer programs for teaching high school earth science, biology and chemistry.

The plastics commonly used in household garbage bags take, on average, 100 years to decompose in landfills. From an environmental standpoint, the plastic bag industry should be forced to switch to newly developed plastics, which begin to decompose after only 20 years.

Which of the following pieces of information would be most helpful in evaluating the argument above?

(A) the rate of growth or decline in sales of plastic garbage bags

(B) the number of plastic garbage bags sold last year that eventually wound up in landfills

(C) the feasibility of enforcing legislation that regulates the plastics used in garbage bags

(D) the length of time it takes the newly developed plastic to fully decompose in landfills.

(E) a comparison of the production cost of one bag made with the old plastics and of one bag made with the new plastics

To avoid the appearance of conflicts of interest, the board of a major U.S. stock exchange is considering a new policy that would ban former top executives of the exchange from taking positions at publicly traded companies for a period of two years after leaving the stock exchange. Critics of the plan say the policy is unfair because it would likely prevent former top executives of the exchange from earning a decent living.

Which of the following statements, if true, would most strengthen the prediction made by the critics of the proposed company policy?

(A)The labor union that represents most of the stock exchange’s employees has made public statements that threaten a strike if the policy is adopted.

(B) Former employees of the exchange most often work for publicly traded companies after leaving the exchange.

(C) Low-level managers at the exchange have an average tenure of 13 years, one of the longest in the industry.

(D) Low-level managers at the exchange most often leave their jobs for positions with the state or federal government.

(E) Former top executives of the exchange have a particular set of skills such that they are usually only able to find work with publicly traded companies.

Several people have died while canoeing during high water on a nearby river in recent years. The local police have proposed a ban on canoeing when the river reaches flood stage. Opponents of the ban argue that the government should ban an activity only if it harms people other than those who willingly participate in the activity, and they, therefore, conclude that the proposed ban on high-water canoeing is unwarranted.

Which of the following, if true, most seriously weakens the opponents' conclusion?

A. Sailboats are not allowed on a nearby lake when winds exceed 50 miles per hour.

B. Several other local governments have imposed similar bans on other rivers.

C. Several police officers have been seriously injured while trying to rescue canoeists who were stranded on the Over while attempting to canoe during high water.

D. More canoeists drown while canoeing rivers at normal water levels than while canoeing rivers at high water levels.

E. Statistics provided by the U.S. National Park Service show that fewer people drown on rivers with high-water canoeing bans than on rivers without such bans.

______________________________________
CR 1

Social worker: Typically, physicians in the United States who promote specialized services do not charge as much as do physicians who do not promote their services at all. Every time physicians are allowed to promote without restriction, the number of physicians promoting their specialty service has gone up, and patients have paid less for these consultations. Recent changes in regulations of such promotions have lifted the requirement that the amount charged for a consultation appear on the promotion. An effect of this change will be that physicians will no longer be inclined to reduce their fees when they start to promote, and many physicians who promote their services will increase their charges to patients.

In the above argument, the two parts in boldface play which of the following roles?

A. The first makes a general claim that the social worker takes to be the truth; the second is proposed as an outcome resulting from the general claim’s truth.

B. The first supplies an action and a consequence that the social worker argues will be replicated; the second recognizes a situation that would cause the action and consequence to fall apart.

C. The first supplies an action and a consequence that the social worker perceives will no longer hold true; the second gives an explanation to support that perception.

D. The first provides clarification that the social worker presents in advocacy of a prediction; the second is that prediction.

E. The first recognizes a perspective that opposes the point that the social worker advocates; the second is that point.

CR 2

A. many taxpayers are only concerned with receiving their refund checks

B. a friendlier public image for the IRS will increase voluntary compliance with tax laws

C. the timely collection of taxes could not be maintained if most taxpayers did not have a respectful fear of the IRS

D. fewer taxpayers fear the IRS today than feared it 10 years ago

E. collecting delinquent taxes does not necessarily cost the government more than collecting taxes on time
