rice strain is high yield or low yield. If you thought C means the rice strain has potential to grwo more rice per acre, which is apparently a misunderstanding, the argument has said that ...nor will rice yields per acre increase appreciably 反对前提 GWD6Q4: In the past the country of Siduria has relied heavily on imported oil. Siduria recently implemented a program to convert heating systems from oil to natural gas. Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Sidurian reliance on foreign sources for fuel should decline soon. Which of the following is an assumption on which the argument depends? In Siduria the rate of fuel consumption is rising no more quickly than the rate of fuel production. Domestic production of natural gas is rising faster than is domestic production of oil in Siduria. No fuel other than natural gas is expected to be used as a replacement for oil in Siduria. Buildings cannot be heated by solar energy rather than by oil or natural gas. All new homes that are being built will have naturalgasburning heating systems. GWD6Q38: Three large panies and seven small panies currently manufacture a product with potential military applications. If the government regulates the industry, it will institute a single set of manufacturing specifications to which all ten panies will have to adhere. In this case, therefore, since none of the seven small panies can afford to convert their production lines to a new set of manufacturing specifications, only the three large panies will be able to remain in business. Which of the following is an assumption on which the author‟s argument relies? None of the three large panies will go out of business if the government does not regulate the manufacture of the product. It would cost more to convert the production lines of the small panies to a new set of manufacturing specifications than it would to convert the production lines of the large panies.不一定是小的成本比大的成本高，而是同样的成本小的承担不起大的可以承担。 Industry lobbyists will be unable to dissuade the government from regulating the industry. Assembly of the product produced according to government manufacturing specifications would be more plex than current assembly procedures. None of the seven small panies currently manufactures the product to a set of specifications that would match those the government would institute if the industry were to be regulated. 如果一开始就有小公司已经符合新规定，那么它没有必要 Convert也就不存在能否 Afford的问题了。 Q 18: Most household appliances use electricity only when in use. Many microwave ovens, However, have builtin clocks and so use some electricity even when they are not in Use. The clocks each consume about 45 kilowatthours per year. Therefore, house Holds whose microwave oven has no builtin clock use 45 kilowatthours per year Less. On average, than do parable households shoes microwave oven is other Wise similar but has a builtin clock. The oven that has not builtin clock=T The oven that has builtin clock=T‟+45 kilowatthours The statement: T‟+45T=45. Assumption: T=T‟ Which of the following is an assumption on which the argument depends? Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven. Microwave ovens with a builtin clock do not generally cost more to buy than microwave ovens without a builtin clock. All households that have a microwave oven also have either a gas oven or a Conventional electric oven. Households whose microwave oven does not have a builtin clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one. There are more households that have a microwave oven with a builtin clock than there are households that have a microwave oven without a builtin clock. GWD7Q5: Exposure to certain chemicals monly used in elementary schools as cleaners or pesticides causes allergic reactions in some children. Elementary school nurses in Renston report that the proportion of schoolchildren sent to them for treatment of allergic reactions to those chemicals has increased significantly over the past ten years. Therefore, either Renston‟s schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them than schoolchildren were ten years ago. 因对化学物质过敏而被送到小医院的学生增多 学生 exposed to 更多化学物质或更敏感。 GAP Which of the following is an assumption on which the argument depends? i The number of school nurses employed by Renston‟s elementary schools has not decreased over the past ten years. Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances. Children who have allergic reactions to the chemicals are not more likely to be sent to a school nurse now than they were ten years ago. NOT+他因 削弱 The chemicals are not monly used as cleaners or pesticides in houses and apartment buildings in Renston. Children attending elementary school do not make up a larger proportion of Renston‟s population now than they did ten years ago. GWD7Q27: A significant number of plex repair jobs carried out by Ace Repairs have to be reworked under the pany‟s warranty. The reworked jobs are invariably satisfactory. When initial repairs are inadequate, therefore, it is not because the mechanics lack petence。 rather, there is clearly a level of focused concentration that plex repairs require that is elicited more reliably by rework jobs than by firsttime jobs. The argument above assumes which of the following? There is no systematic difference in membership between the group of mechanics who do firsttime jobs and the group of those w。
