麻烦LZ 再看看那个 戒烟药的逻辑 是这道PREP原题吗？ 谢谢
In Borania many people who want to quit smoking wear nicotine skin patches, which deliver small doses of nicotine through the skin. Beginning next month, these patches can be purchased without a doctor's prescription. Although nonprescription patches will be no more effective than those obtained by prescription and will be equally expensive, patch manufacturers are nevertheless predicting that the patches' new nonprescription status will boost sales, which have slowed considerably in recent years.
Which of the following, if true in Borania, most strongly supports the manufacturers' prediction?
A. Most people who wanted to quit smoking and who found the nicotine skin patch helpful in quitting have quit.
B. Nicotine skin patches generally cost more to use than do other types of aids that help people to quit smoking.
C. Several nonprescription aids aimed at helping people to quit smoking have been widely available for a number of years.
D. Many smokers who want to quit smoking feel that they cannot afford to visit a doctor for a prescription. (Answer)
E. People who use nicotine skin patches have approximately the same rate of success in quitting smoking as do people who use other aids aimed at helping people to quit smoking.-- by 会员 jenny1989 (2010/10/24 14:46:52)
恩。。不是这题哈，gmac把这题给改了，但是刚开始的两句的背景叙述是一样的，接着就像我寂静上面的，讲了一个n开头的patch变成了非处方药，然后另外一个freesmoker还是一样的没有变是处方药，然后第一次n比f便宜了，接着就说了个结论n销量要增加，f要减少。 |
