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?qū)瘜W(xué)物質(zhì)過敏而被送到小醫(yī)院的學(xué)生增多 學(xué)生 exposed to 更多化學(xué)物質(zhì)或更敏感。 There is no pany that successfully petes with Ace Repairs for plex repair jobs.

This year, previously established panies will not be adding as many new jobs overall as such panies added last year. Therefore, unless a record number of panies start up this year, Derderia will not break its record for new jobs created. 同時發(fā)生：新公司成立，舊公司提供更多工作 新工作數(shù)量創(chuàng)紀錄 Which of the following is an assumption on which the argument relies? A. In a given year, new panies starting up create more new jobs on average than do previously established panies. 1 不確定性， 2 反了，只說了削弱沒有 NOT B. The number of people seeking employment is no larger this year than it was last year. C. This year, the new panies starting up will not provide substantially more jobs per pany than did new panies last year. New jobs=pany的數(shù)量 *平均每 pany提供的工作崗位的數(shù)量 D. Previously established panies in Derderia will be less profitable this year than such panies were last year. E. The number of jobs created in the Derderian economy last year was substantially larger than the number of jobs lost.[C] A錯：原文結(jié)論是新工作沒去年多。比較對象錯誤。 D. Fairmont and Greatport are the cities with the highest collisiondamage insurance rates. E. The insurance panies were already aware of the difference in the likelihood of collisions before the publication of the police reports.[A] GWD9Q40: Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods. All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there. Which of the following is an assumption on which the argument depends? A. People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced. B. There are no plants native to western Africa that, if domesticated, could serve as staple food crops. 沒有涉及關(guān)鍵問題：時間 C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa. D. Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are. E. Kola and okra were domesticated in western Africa before rice and yams were introduced there. Answer:A B 取非為 There are some plants native to western Africa that, if domesticated, could serve as staple food crops 因為即使這樣，你不知這些 PLANTS domesticated是在 rice and yams were introduced into western Africa 之前 還是之后，如果之后，則結(jié)論仍能成立。必要型假設(shè)題有兩類： DEFENDER（排除其他可能性，排除削弱或攻擊結(jié)論成立的可能性因素）和 SUPPORTER（ GAP），顯然該題屬于 DEFENER類 1。等等。原文計算海洋最大年數(shù)的方法： current salt levels （即現(xiàn) 在海洋的鹽的濃度或水平）除以 resulting increase 。 3。所以不是答案。一個 hundred有加 “S”，一個沒有。 原文的主題意思：先算出過去一百年的鹽度增加，再算出海洋從鹽度為零到目前鹽度需要花多少個世紀（一個世紀正好一百年）的這種增加量。這種算法可以精確算出海洋最大年齡 A。取非。如果消耗掉的鹽發(fā)生在過去一百年以外，則
