In Borania many people who want toquit smoking wear nicotine skin patches, which deliver small doses of nicotinethrough the skin. Beginning next month,these patches can be purchased without a doctor's prescription. Although nonprescription patches will be nomore effective than those obtained by prescription and will be equallyexpensive, patch manufacturers are nevertheless predicting that the patches'new nonprescription status will boost sales, which have slowed considerably inrecent years.
Which of the following, if true inBorania, most strongly supports the manufacturers' prediction?
A. Most people who wanted to quitsmoking and who found the nicotine skin patch helpful in quitting have quit.
B. Nicotine skin patches generallycost more to use than do other types of aids that help people to quit smoking.
C. Several nonprescription aidsaimed at helping people to quit smoking have been widely available for a numberof years.
D. Many smokers who want to quitsmoking feel that they cannot afford to visit a doctor for a prescription.
E. People who use nicotine skinpatches have approximately the same rate of success in quitting smoking as dopeople who use other aids aimed at helping people to quit smoking.
想请问，A为什么不对哪？那些想要戒烟而且发现patch有用的人都戒了烟，不正好说明patch有用，所以非处方的也会大卖吗？
我也觉得解释的有点牵强，但我还是不是很清楚的明白，为什么A不行，求牛人解答，谢谢~~

个人认为：文中提到Although nonprescription patches will be nomore effective than those obtained by prescription and will be equally expensive，这就是说处方的PATCH更有效而且和非处方的PATCH价钱一样，这里注意，文章比的是处方的和非处方的优劣，所以答案也需要表明处方的patch的劣处。A没有解释这个问题：既然处方药比非处方药好，那为什么还用非处方；而D解释了这个问题。

我还想问一下prep08 cr1 74 为啥不选E啊，我好纠结....
74. (29534-!-item-!-188;#058&004138)

In a certain wildlife park, park rangers are able to track the movements of many rhinoceroses because those animals wear radio collars. When, as often happens, a collar slips off, it is put back on.

utting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart. Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females.

robably, therefore, some substance in the tranquilizer inhibits fertility.
In evaluating the argument, it would be most useful to determine which of the following?
A. Whether there are more collared female rhinoceroses than uncollared female rhinoceroses in the park
B. How the tranquilizer that is used for immobilizing rhinoceroses differs, if at all, from tranquilizers used in working with other large mammals
C. How often park rangers need to use tranquilizer darts to immobilize rhinoceroses for reasons other than attaching radio collars
D. Whether male rhinoceroses in the wildlife park lose their collars any more often than the park’s female rhinoceroses do
E. Whether radio collars are the only practical means that park rangers have for tracking the movements of rhinoceroses in the park

谢谢，你的解释很清楚。74的话的确是很纠结的一题。
我觉得不选E的原因是，E说雷达是否是唯一实用的方法去追踪犀牛，文中要解释的是麻醉药是否影响生育能力，与雷达对于追踪犀牛是否实用无关。
不知道你是怎么想的，你能说说吗？

哦，所以落脚点是麻醉药和生育能力，不是雷达和生育能力，懂了！谢谢~
