※ 引述《chenemily (天天保持好心情)》之銘言： : From 1980 to 1989, total consumption of fish in the country of Jurania : increased by 4.5 percent, and total consumption of poultry products there : increased by 9.0 percent. During the same period, the population of Jurania : increased by 6 percent, in part due to immigration to Jurania from other : countries in the region. : If the statements above are true, which of the following must also be true on : the basis of them? : A. During the 1980s in Jurania, profits of wholesale distributors of poultry : products increased at a greater rate than did profits of wholesale : distributors of fish. : B. For people who immigrated to Jurania during the 1980s, fish was less : likely to be a major part of their diet than was poultry. : C. In 1989 Juranians consumed twice as much poultry as fish. : D. For a significant proportion of Jurania's population, both fish and : poultry products were a regular part of their diet during the 1980s. : E. Per capita consumption of fish in Jurania was lower in 1989 than in 1980 : 想請問一下這題 : (A)profits 刪 : (C)consumed twice as much poultry as fish 刪 : (D)both fish and poultry regular part of their diet 刪 : 我最後再B & E 猶豫了很久我選了B : 請問B & E要怎麼想比較合理尤其E考試的時候應該沒時間帶數字吧!! : 謝 must be true的題型著重在題目是否可推出~ 考試沒時間做計算的，不過經由各類型CR的演練，可以得出速解的方式 A：利潤關無法推出 B：移民者飲食習慣的比例無法推出 C：消耗比例無法推出 D：人口比例跟飲食關係無法推出 E：1.045/1.06小於1，相除得出人均少了 (速解法：直接肉眼判斷小於1就是人均少了，大於1就是人均多了) 速解法的實際運算推導： 1980 consumption of fish = a 則1989 fish =1.045a 1980 consumption of poultry =b 則1989 poultry = 1.09b 1980 population=c 則1989 population =1.06c 1.045a/1.06c < a/c 因此人均消費量下降 GMAT的出題模式很多都一樣的，可以透過GWD-8-40來做個驗證喔! 看看它的原文跟正確選項B是否都跟這題有異曲同工之妙呢? 快速掃過B選項1.034/1.05 < 1…正解…1秒換下一題^^ Q40: From 1973 to 1976, total United States consumption of cigarettes increased 3.4 percent, and total sales of chewing tobacco rose 18.0 percent. During the same period, total United States population increased 5.0 percent. If the statements above are true, which of the following conclusions can be properly drawn? A. United States manufacturers of tobacco products had higher profits in 1976 than in 1973. B. Per capita consumption of cigarettes in the United States was lower in 1976 than in 1973. C. The proportion of nonsmokers in the United States population dropped slightly between 1973 and 1976. D. United States manufacturers of tobacco products realize a lower profit on cigarettes than on chewing tobacco. E. A large percentage of United States smokers switched from cigarettes to chewing tobacco between 1973 and 1976.
