202.Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income 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 income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.
Which of the following is an assumption on which the argument depends? (A) The total acreage devoted to grain production in Gortland will not decrease substantially. (B) The population of Gortland has remained relatively constant during the country’s years of growing prosperity. (C) The per capita consumption of meat in Gortland is roughly the same across all income levels. (D) In Gortland, neither meat nor grain is subject to government price controls. E (E) People in Gortland who increase their consumption of meat will not radically decrea
se their consumption of grain.
此题答案E，我也选对了。因为其他答案必错。可是将E取非，并不一定原文不成立啊。“G的人减少了grain的消耗，但是因为肉的需求增长太快，所以G还是得进口肉或谷物”。因为之前在分不清楚改选不改选的时候，用取非法是可以最终选择到对的答案的。如下。可是这里不灵了，晕倒啊。请NN帮忙！
171. A recent report determined that although only three percent of drivers on Maryland highways equipped their vehicles with radar detectors, thirty-three percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.
The conclusion drawn above depends on which of the following assumptions? (A) Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.***A虽然对conclusion有帮助，但并非不存在会使conclusion不成立!! (B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed. (C) The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors. (D) Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report. B (E) Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report. 此题曾在A\B间徘徊，最终就是用取非法排除的A！！ |
