The Calex Telecommunications Company is planning to introduce cellular telephone service into isolated coastal areas of Caladia, a move which will require considerable investment. However, the only significant economic activity in these areas is small-scale coffee farming, and none of the coffee farmers make enough money to afford the monthly service fees that Calex would have to charge to make a profit. Nevertheless, Calex contends that making the service available to these farmers will be profitable.
Which of the following, if true, provides the strongest support for Calex's contention?
(A) Currently, Caladian coffee farmers are forced to sell their coffee to local buyers at whatever price those buyers choose to pay because the farmers are unable to remain in contact with outside buyers who generally offer higher prices. 答案是这个，我想问，被要求以低价卖出不更说明了他们没钱么~这个正确选项没想通~
19. (27788-!-item-!-188;#058&003653) With a record number of new companies starting up in Derderia and with previously established companies adding many jobs, a record number of new jobs were created last year in the Derderian economy. This year, previously established companies will not be adding as many new jobs overall as such companies added last year. Therefore, unless a record number of companies start up this year, Derderia will not break its record for new jobs created.
Which of the following is an assumption on which the argument relies?
(C) This year, the new companies starting up will not provide substantially more jobs per company than did new companies last year. 这个正确选项也是，题目说要建新的公司才有可能打破记录，但是这跟新公司提供的工作数量没关系的吧~~~没弄清

During the past year, Pro-Tect Insurance Company's total payout on car-theft claims has been larger than the company can afford to sustain.【事实】 ro-Tect cannot reduce the number of car-theft policies it carries, so it cannot protect itself against continued large payouts that way.【consideration】 Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.【strategy】 Many policyholders will respond to the discount by installing such devices,【效果】 since the amount of the discount will within two years typically more than cover the cost of installation.【产生效果的原因】 Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.【结论】
In the argument above, the two portions in boldface play which of the following roles?
（答案是B，请解释下B/E，这些措辞assessment、judgement等啥意思~？我做BF题也老错，指出个方法好么~） (B) The first presents a problem a response to which the argument assesses; the second is the judgment reached by that assessment. (E) The first presents a development whose likely outcome is at issue in the argument; the second is a judgment the argument uses in support of its conclusion about that outcome. 谢谢橘子同学~
求助这题·· 不明白为什么B起到削弱作用··· 157. Companies O and P each have the same number of employees who work the same number of hours per week. According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P. Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.
Which of the following, if true, would most weaken the conclusion above? (A) The employees of Company P lost more time at work due to job-related accidents than did the employees of Company O. (B) Company P considered more types of accidents to be job-related than did Company O. (C) The employees of Company P were sick more often than were the employees of Company O. (D) Several employees of Company O each had more than one job-related accident. (E) The majority of job-related accidents at Company O involved a single machine.
求助楼主GWD12-29 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. eople 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. 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.
正确答案是A 可是看不懂A是什么意思？我理解的是 西非的人就没有发展他们停止种植的主要作物， 一旦大米和山药被引进。 staple crops that they stopped cultivating 是不是说明他们在大米和山药引进前 就已经有主要作物了？ 请求解答
迷茫中求助楼主啊~！PREP旧1-21 这个题我明白ACE都不对，可是就是B和D选项不明白~为什么选D呢？ 21. (28551-!-item-!-188;#058&003690) Traces of cultivated emmer wheat have been found among the earliest agricultural remains of many archaeological sites in Europe and Asia. 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. 楼主辛苦了~！各种感谢啊~！！！
Canadians now increasingly engage in "out-shopping," which is shopping across the national border, where prices are lower. Prices are lower outside of Canada in large part because the goods-and-services tax that pays for Canadian social services is not applied. Which one of the following is best supported on the basis of the information above? (A)If the upward trend in out-shopping continues at a significant level and the amounts paid by the government for Canadian social services are maintained, the Canadian goods-and-services tax will be assessed at a higher rate. (B)If Canada imposes a substantial tariff on the goods bought across the border, a reciprocal tariff on cross-border shopping in the other direction will be imposed, thereby harming Canadian businesses. (C)The amounts the Canadian government pays out to those who provide social services to Canadians are increasing. (D)The same brands of goods are available to Canadian shoppers across the border as are available in Canada. (E)Out-shopping purchases are subject to Canadian taxes when the purchaser crosses the border to bring them into Canada. 用排除法，我可以做出来，但是A为什么是对的那？ Twenty percent of all energy consumed in the United States is consumed by home appliances. If appliances that are twice as energy- efficient as those currently available are produced, this figure will eventually be reduced to about ten percent.The argument above requires which of the following assumptions? (A) Home-appliance usage would not increase along with the energy efficiency of the appliances. (B) It would not be expensive to produce home appliances that are energyefficient. (C) Home-appliance manufacturers now have the technology to produce appliances that are twice as energy-efficient as those currently available. (D) The cost of energy to the consumer world rise with increases in the energy efficiency of home appliances. (E) The percentage of energy consumed by home appliances will increase if existing appliances are not replaced by more energy-efficient models. 为什么C不行，是因为C不对还是不如A好 希望得到帮忙 3Q
