Goal: Souper wishes to achieve continued rapid sales growth in Danport over the next two years. Proposal for consideration: Continue to open new restaurants in Danport during the next two years at the same rate as in the last two years. In light of the situation, which of the following, if true, most strongly argues that adopting the proposal would be an ineffective way of achieving the goal? (A) At times at which customers find Souper restaurants too crowded, they often go to other restaurants nearby. (B) The Souper chain has generally opened new restaurants in locations that are in the vicinity of a large number of other restaurants. (C) Souper restaurants generally offer a much smaller variety of foods than many of the other restaurants in their vicinity. (D) Virtually all potential sites for new Souper restaurants in Danport are located in the vicinity of existing Souper restaurants. (E) Souper restaurants have always offered meals that are somewhat less expensive than meals at restaurants that pete with Souper for patrons. 答案是 D， 能開分店的地方已經(jīng)開滿自家的店了 ， 所以不能通過開分店的方式賺更多 錢 41. 有一題說古代羅馬人發(fā) 現(xiàn)希臘人嚼月桂樹的葉子以 reduce… ，于是一個(gè)傻 科學(xué)家找了Greek 月桂樹葉嚼，發(fā)現(xiàn)沒有 reduce… 于是他認(rèn)為羅馬人的記敘是錯(cuò)誤的。 問 weaken？ 39. GWD8Q3：： In the late 1980s, the population of sea otters in the North Pacific began to decline. There are two plausible explanations for the decline: predation, possibly by killer whales, or disease. Of these two, disease is the more likely, since a concurrent sharp decline in populations of seals and sea lions is believed to have been caused by disease, and diseases that infect these creatures are likely to be able to infect sea otters also. Which of the following, if true, most seriously weakens the reasoning? A. Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey. B. There is no indication that the sea otter population at any North Pacific location declined in the 1980s because of substantial numbers of sea otters migrating to other locations. C. Along the Pacific coast of North America in the 1980s,sea otters were absent from many locations where they had been relatively mon in former times. D. Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters39。然后經(jīng)濟(jì)發(fā)展就停滯了，這時(shí)這個(gè)國家的 emigration 也增多了。 然后支持（或者解釋）這個(gè)專家的想法。 37. 一個(gè)公司，說它不像別的大型連鎖公司一樣，它的每個(gè)分店的 manager 都有權(quán)利去決定purchase 什么東西（具體什么忘記了，似乎不重要），因?yàn)槊總€(gè)分店都有自己的 direct supplier。 問解釋。 答案： 作者以為不還 check 就不會(huì)產(chǎn)生通脹 36. Unemployment 定義為在多長時(shí)間內(nèi)連一份 part time job 都沒有。作者認(rèn)為政府自己創(chuàng)造了一個(gè)問題又進(jìn)而花氣力去探究這個(gè)問題的原因。一個(gè)顯著的例子就是食品價(jià)格的飛漲。 問哪個(gè)能 strengthen 結(jié)論？ 35. 一個(gè)國家遭遇了經(jīng)濟(jì)蕭條，作為應(yīng)對(duì)政府把稅收以 check 支票形式 直接返還給人民。 答案 ： 一種長在水里的 plankton由于受到從陸地上吹來的 dust生長的很好 ， 吸收了很多 CO2。 32. 先介紹 Plants可以 absorb CO2, 然后退回到一個(gè)什么 glacier period, 那 是氣候 dry and cold, so 只有 less plants， 所以按理說 atmosphere 中的 CO2 應(yīng)該較高 ， 然而科學(xué)研究表明那個(gè)時(shí)期的 atmosphere 中的 CO2 并沒有升高。 有一個(gè)廠商只制造的車只占 4%的市場(chǎng)份額 ， 但是卻需要支付的罰款占到所有罰款的 75%。 有人說收的稅遠(yuǎn)超維護(hù)所需 。s population has remained relatively stable. 答案： B 29. Country A pushes a high tariff on the import of cars from other country, making the price of imported cars in country A extremely high. Recently, Country A lift the high tariff on the import of cars, the car manufactures of other country, however, still do not want to export cars to country A. Q: which of the following can explain this situation? 答案： 這個(gè) A 國家的公路對(duì)車子的要求很高。 28. Gortland has long been narrowly selfsufficient in both grain and meat. However, as per capita ine in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita ine continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import grain. Which of the following is an assumption on which the argument depends? 08Prep 279（（ 變變 體體 ）） : The country of Baurisia has, until now, been selfsufficient in both grain and meat. However, with growing prosperity in Baurisia has e a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita ine in Baurisia is almost certain to rise further but increases in domestic grain production are highly unlikely, Baurisia is soon likely to bee an importer of grain. Which o
