小白同学呢??又要来救火啦~~~ 这条CR也是没有能想的很明白: 83. Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.
Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above? (A) Although it sells all of the telephones that it produces, Mammoth Industries’ share of all telephone sales has declined over the last year. (B) Mammoth Industries’ average inventory of telephones awaiting shipment to retailers has declined slightly over the last year. (C) Advertising has made the brand name of Mammoth Industries’ telephones widely known, but few consumers know that Mammoth Industries owns this brand. (D) Mammoth Industries’ telephone is one of three brands of telephone that have together accounted for the bulk of the last year’s increase in sales. E (E) Despite a slight decline in the retail price, sales of Mammoth Industries’ telephones have fallen in the last year. 正确答案是E,但是我选的是A.我不知道E中这个decline in the retail price究竟从哪里冒出来的...真是要吐血了... In tests for pironoma, a serious disease, a false positive result indicates that people have pironoma when, in fact, they do not; a false negative result indicates that people do not have pironoma when, in fact, they do. To detect pironoma most accurately, physicians should use the laboratory test that has the lowest proportion of false positive results.
Which of the following, if true, gives the most support to the recommendation above? (A) The accepted treatment for pironoma does not have damaging side effects. (B) The laboratory test that has the lowest proportion of false positive results causes the same minor side effects as do the other laboratory tests used to detect pironoma. (C) In treating pironoma patients, it is essential to begin treatment as early as possible, since even a week of delay can result in loss of life. (D) The proportion of inconclusive test results is equal for all laboratory tests used to detect pironoma. E (E) All laboratory tests to detect pironoma have the same proportion of false negative results.
这题我选了B,但是正确答案是E.真是让人想去死啊...... PS,这几天洋洋同学和宝儿很安静的嘛.....都不出来冒泡了...
