      At several locations on the northwest coast of North America are formations known as chevrons—wedge-shaped formations of mounded sediment—pointing toward the ocean. Most geologists take them to have been formed by erosion, but recently other scientists have proposed that they were thrown up from the ocean by massive waves triggered by meteor impacts in the Pacific Ocean. Which of the following, if discovered, would most help in deciding which hypothesis is correct?

      Although Ackerburg’s subway system is currently operating at a deficit, the transit authority will lower subway fares next year. The authority projects that the lower fares will result in a ten percent increase in the number of subway riders. Since the additional income from the larger ridership will more than offset the decrease due to lower fares, the transit authority actually expects the fare reduction to reduce or eliminate the subway system’s operating deficit for next year. Which of the following, if true, provides the most support for the transit authority’s expectation of reducing the subway system’s operating deficit?

      In its search for new technologies for solar energy that can produce lower-cost electricity, Smith-Diatom is developing a new way to make dye-sensitive solar cells, in which photons strike light-sensitive dyes. The process uses diatoms, which are unicellular algae that have silicon shells with a complex structure. First, the organic material is removed, and then the shells are coated with a titanium dioxide film that acts as a semiconductor. The diatoms’ structure results in more photon activity and thus more efficient production of electricity than with current dye-sensitized solar cells, which in turn lowers the cost. Which of the following considerations would, if true, most strongly support the hypothesis that the plan, if implemented, will produce low-cost electricity from dye-sensitive solar cells?

      The XCT automobile is considered less valuable than the ZNK automobile, because insurance companies pay less, on average, to replace a stolen XCT than a stolen ZNK. Surprisingly, the average amount insurance companies will pay to repair a car involved in a collision is typically higher for the XCT than for the ZNK. One insurance expert explained that repairs toXCT automobiles are especially labor-intensive, and labor is a significant factor in collision repair costs. Which of the following, if true, most strongly supports the insurance expert’s explanation?

      Stockholders have been critical of the Flyna Company, a major furniture retailer, because most of Flyna’s furniture is manufactured in Country X from local wood, and illegal logging is widespread there. However, Flyna has set up a certification scheme for lumber mills. It has hired a staff of auditors and forestry professionals who review documentation of the wood supply of Country X’s lumber mills to ensure its legal origin, make surprise visits to mills to verify documents, and certify mills as approved sources of legally obtained lumber. Flyna uses only lumber from certified mills. Thus, Flyna’s claim that its Country X wood supply is obtained legally is justified. Which of the following, if true, would most undermine the justification provided for Flyna’s claim?

      OG2021-803A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the greatest price the market will bear when they have such a product. But large profits on the new product will give competitors a strong incentive to quickly match the new product's capabilities. Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price. In the argument above, the two portions in boldface play which of the following roles?

      OG2021-798Political Strategist: The domestic policies of our opponents in Party X are contrary to the priorities of many middle-class voters.

In order to win these voters back, we in Party Y must prove to middle-class voters that Party X does not represent their priorities with respect to domestic policy. Which of the following would, if true, most strongly suggest that the political strategist's plan is unlikely to succeed?

      OG2021-786Lockeport's commercial fishing boats use gill nets, which kill many of the netted fish, including some fish of endangered species. The fishing commission has proposed requiring the use of tent nets, which do not kill fish; boat crews would then throw back fish of endangered species. Profitable commercial fishing boats in similar areas have already switched over to tent nets. The proposal can therefore be implemented without economic harm to Lockeport's commercial fishing boat operators. Which of the following, if true, casts the most serious doubt on the argument made for the proposal?

      OG2021-778The country of Virodia has, until now, been barely self-sufficient in both meat and grain. Greater prosperity there has gone hand in hand with steadily increasing per capita consumption of meat, and it takes several pounds of grain used as feed to produce one pound of meat. Per capita income is almost certain to rise further, yet increases in domestic grain production are unlikely. Which of the following is most strongly supported by the information given?
