The only place where the wild form of emmer wheat has been found growing is a relatively narrow strip of southwest Asia. Since the oldest remains of cultivated emmer wheat yet found are from village sites in the same narrow strip, it is clear that emmer wheat was first domesticated somewhere in that strip. Which of the following, if true, most strengthens the argument? (A) The present-day distribution of another wild wheat, einkorn, which was also domesticated early in the development of agriculture, covers a much larger area of southwest Asia. (B) Modern experiments show that wild emmer wheat can easily be domesticated so as to yield nearly as well as traditionally domestic strains. (C) At the time when emmer wheat was first cultivated, it was the most nutritious of all the varieties of grain that were then cultivated. (D) In the region containing the strip where wild emmer wheat has been found, climatic conditions have changed very little since before the development of agriculture. (E) It is very difficult, without genetic testing, to differentiate the wild form of emmer wheat from a closely related wild wheat that also grows in southwest Asia. 答案D 可是我觉得这题五个答案都很烂 就算是D感觉也没有很强力啊 应该是我的理解有错 拜托哪位大哥指点一下 34. (31982-!-item-!-188;#058&005681) For several years, per capita expenditure on prescription drugs in Voronia rose by fifteen percent or more annually. In order to curb these dramatic increases, the ministry of health prohibited drug manufacturers from raising any of their products' prices. Even though use of prescription drugs did not expand after this price freeze, per capita expenditure for prescription drugs continued to increase by a substantial percentage each year. Which of the following, if true, most helps to explain why the ministry's action did not achieve its goal? (A) After price increases were prohibited, drug manufacturers concentrated on producing new medications to replace existing products. (B) The population of Voronia rose steadily throughout the period. (C) Improvements in manufacturing processes enabled drug manufacturers to maintain high profit levels on drugs despite the price freeze. (D) In addition to imposing a price freeze, the government encouraged doctors to prescribe generic versions of common drugs instead of the more expensive brand-name versions. (E) After price increases were prohibited, some foreign manufacturers of expensive drugs ceased marketing them in Voronia. 答案A 可是这题我从题目开始就雾煞煞 禁止药物价格上升会抑制处方药的平均每人使用量吗 唉 我真的很笨 应该也是整个理解错了 有没有人可以帮我从题目意思到A为什麽对解释一下吗 36. (32124-!-item-!-188;#058&006025) Outsourcing is the practice of obtaining from an independent supplier a product or service that a company has previously provided for itself. Vernon, Inc., a small manufacturing company that has in recent years experienced a decline in its profits, plans to boost its profits by outsourcing those parts of its business that independent suppliers can provide at lower cost than Vernon can itself. Which of the following, if true, most strongly supports the prediction that Vernon's plan will achieve its goal? (A) Among the parts of its business that Vernon does not plan to outsource are some that require standards of accuracy too high for most independent suppliers to provide at lower cost than Vernon can. (B) Vernon itself acts as an independent supplier of specialized hardware items to certain manufacturers that formerly made those items themselves. (C) Relatively few manufacturers that start as independent suppliers have been able to expand their business and become direct competitors of the companies they once supplied. (D) Vernon plans to select the independent suppliers it will use on the basis of submitted bids. (E) Attending to certain tasks that Vernon performs relatively inefficiently has taken up much of the time and effort of top managers whose time would have been better spent attending to Vernon's core business. 答案E 可是这题既然是要支持boost profit的目标 managers的time好像不是重点吧 我反而觉得A比较有说服力啊 照A的讲法 这家公司的所有成本应该都是最低了吧 至少会跟原题比较相关啊 可是我想应该还是我理解错误了 拜托大大们在帮我解惑一次吧 感谢各位了 --
