Many large department stores in Montalia now provide shopping carts for their customers. Since customers using shopping carts tend to buy more than those without shopping carts, most of these stores are experiencing strong sales growth, while most other department stores are not. Therefore, in order to boost sales, managers of Jerrod’s, Montalia’s premier department store, are planning to purchase shopping carts and make them available to the store’s customers next month.
Which of the following, if true, casts most doubt whether the managers’ plan, if implemented, will achieve its goal?
A. Since most customers associate shopping carts with low-quality discount stores, Jerrod’s high-quality image would likely suffer if shopping carts were introduced.
B. Because the unemployment rate has declined to very low levels, Jerrod’s now has to pay significantly higher wages in order to retain its staff.
C. A number of department stores that did not make shopping carts available to their customers have had to close recently due to falling profits.
D. Shopping carts are not very expensive, but they generally need to be replaced every few years.
E. Stores that make shopping carts available to their customers usually have to hire people to retrieve the carts from parking areas.
这题好像是prep逻辑的变体，不太明白选A的理由。
The Eurasian ruffe, a fish species inadvertently introduced into North America’s Great Lakes in recent years, feeds on the eggs of lake whitefish, a native species, thus threatening the lakes’ natural ecosystem. To help track the ruffe’s spread, government agencies have produced wallet-sized cards about the ruffe. The cards contain pictures of the ruffe and explain the danger they pose; the cards also request anglers to report any ruffe they catch.
Which of the following, if true, would provide most support for the prediction that the agencies’ action will have its intended effect?
A. The ruffe has spiny fins that make it unattractive as prey.
B. Ruffe generally feed at night, but most recreational fishing on the Great Lakes is done during daytime hours.
C. Most people who fish recreationally on the Great Lakes are interested in the preservation of the lake whitefish because it is a highly prized game fish.
D. The ruffe is one of several nonnative species in the Great Lakes whose existence threatens the survival of lake whitefish populations there.
E. The bait that most people use when fishing for whitefish on the Great Lakes is not attractive to ruffe.
A diet high in saturated fats increases a person’s risk of developing heart disease. Regular consumption of red wine reduces that risk. Per-capita consumption of saturated fats is currently about the same in France as in the United States, but there is less heart disease there than in the United States because consumption of red wine is higher in France. The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.
Which of the following, if true, most helps to account for the lack of convergence noted above?
A. Consumption of saturated fats is related more strongly to the growth of fatty deposits on artery walls, which reduce blood flow to the heart, than it is to heart disease directly.
B. Over the past 30 years, per-capita consumption of saturated fats has remained essentially unchanged in the United States but has increased somewhat in France.
C. Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly.
D. Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than In the United States.
E. Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age.
这道题主要是不明白题干最后一句话的意思。
Editorial in Krenlandian Newspaper:
Krenland’s steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties. But whatever the cause, the cost is ultimately going to be jobs in Krenland’s steel industry. Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
Which of the following, if true, most seriously weakens the editorial’s argument?
A. Because steel from Krenland is rarely competitive in international markets, only a very small portion of Krenlandian steelmakers’ revenue comes from exports.
B. The international treaties that some governments are violating by giving subsidies to steelmakers do not specify any penalties for such violations.
C. For many Krenlandian manufacturers who face severe international competition in both domestic and export markets, steel constitutes a significant part of their raw material costs.
D. Because of advances in order-taking, shipping, and inventory systems, the cost of shipping steel from foreign producers to Krenland has fallen considerably in recent years.
E. Wages paid to workers in the steel industry in Krenland differ significantly from wages paid to workers in many of the countries that export steel to Krenland.
