Unformatted text preview: C. The experiments showed that the caterpillars were not harmed by contact with the pollen from the genetically modified plants unless they ingested it. D. The maize-eating insects that the natural insecticide protects against do not feed on the pollen of the maize plant. E. Airborne maize pollen tends to collect on the middle leaves of milkweed plants and monarch caterpillars feed only on the plant’s tender upper leaves. Answer: QX: Certain genetically modified strains of maize produce a powerful natural insecticide. The insecticide occurs throughout the plant, including its pollen. Maize pollen is dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields. Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. Therefore, by using genetically modified maize, farmers put monarch butterflies at risk. Which of the following would it be most useful to determine in order to evaluate the argument? A. Whether the natural insecticide is as effective against maize-eating insects as commercial insecticides typically used on maize are B. Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants C. Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen D. Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant’s pollen E. Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields Answer: ------------------------------------------------------------------------------------------------------------ Q17: A study by the Ocean Wildlife Campaign urged states to undertake a number of remedies to reverse a decline in the shark population, which includes the establishment of size limits for shark catches, closing state waters for shark fishing during pupping season, and requiring commercial fishers to have federal shark permits. A. which includes the establishment of size limits for shark catches, closing B. which includes establishing limits to the size of sharks that can be caught, closing C. which include the establishment of size limits for shark catches, the closing of D. including establishing size limits for shark catches, closing 9 E. including the establishing of limits to the size of sharks that are caught, the closing of Answer: ------------------------------------------------------------------------------------------------------------ Q18: Unlike most other mergers in the utility industry, which have been driven by the need to save money and extend companies’ service areas, the merger of the nation’s leading gas and electric company is intended to create a huge marketing network for the utilities in question with states opening their utility markets to competition....
