28-16: Paper& rint is a chain of British stores selling magazines, books, and stationery products. In Britain, magazines’ retail prices are set by publishers, and the retailer’s share of a magazine’s retail price is 25 percent. Since Paper& rint’s margin on books and stationery products is much higher, the chain’s management plans to devote more of its stores’ shelf space to books and stationery products and reduce the number of magazine titles that its stores carry.
Which of the following, if true, most strongly argues that the plan, if put into effect, will not increase Paper& rint’s profits?
A: Recently magazine publishers, seeking to increase share in competitive sectors of the market, have been competitively cutting the retail prices of some of the largest circulation magazines.
B: In market research surveys, few consumers identify Paper& rint as a book or stationery store but many recognize and value the broad range of magazines it carries.
C: The publisher’s share of a magazine’s retail price is 50 percent, and the publisher also retains all of the magazine’s advertising revenue.
D: Consumers who subscribe to a magazine generally pay less per issue than they would if they bought the magazine through a retail outlet such as Paper& rint.
E: Some of Paper& Print’s locations are in small towns and represent the only retail outlet for books within the community.
28-17: In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks – those with three trailers – had less than a third of the accident rate of single- and double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A: Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
B: No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C: Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
D: In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E: In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks
