今天第一次来逻辑区问问题,只因为被GWD真题逼急了,错误率差不多一半了,打击得要命,如果问了些弱智问题,大家多多包涵~:
Q13: In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.
Which of the following, if true, most seriously weakens the argument?
A. Florida attracts more people who move from one state to another when they retire than does any other state. B. The number of people who move out of Florida to accept employment in other states has increased over the past ten years. C. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees. D. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years. E. The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.
这道题答案D,可我选C。我觉得既然结论是经济会收到影响,那说还有其它经济撑着不是挺好得削弱吗?而D仅仅说退休并移居的人增多了,并不代表就移到Florida啊,况且原文已经说了移来Florida的人少了,那这个也就起不了什么作用了吧。我哪里想错了?
Q14: That the application of new technology can increase the productivity of existing coal mines is demonstrated by the case of Tribnia's coal industry. Coal output per miner in Tribnia is double what it was five years ago, even though no new mines have opened.
Which of the following can be properly concluded from the statement about coal output per miner in the passage?
A. If the number of miners working in Tribnian coal mines has remained constant in the past five years, Tribnia's total coal production has doubled in that period of time. B. Any individual Tribnian coal mine that achieved an increase in overall output in the past five years has also experienced an increase in output per miner. C. If any new coal mines had opened in Tribnia in the past five years, then the increase in output per miner would have been even greater than it actually was. D. If any individual Tribnian coal mine has not increased its output per miner in the past five years, then that mine's overall output has declined or remained constant. E. In Tribnia the cost of producing a given quantity of coal has declined over the past five years.
答案为A,但C和D为什么conclude不出来?
