It takes a particular talent to be a successful business manager. Business courses can help people to solve management problems, but such courses can do so only for those people with managerial talent. Such people should take business courses to acquire ideas that they can subsequently use to good advantage if management problems happen to arise.
If the statements above are true, which of the following must also be true on the basis of them?
(A) People who are helped by business courses in solving management problems also have managerial talent.
(B) People who are already skilled at solving management problems are unlikely to benefit from business courses.
(C) Most ideas that are used successfully in solving management problems are those acquired in business courses.
(D) People who lack managerial talent are more likely to take business courses than are people who have managerial talent.
(E) Those people who have never taken business courses are unable to solve management problems when such problems arise.



我一开始选E,然后选B,可是答案为什么是A啊..
People who are helped by business courses和such courses can do so only for those people中的those people不是同一堆人吗?
还有题干是什么意思,是指原文的前提还是推论?

原文是前提，选项是结论
B不对的原因是 原文的意思是那些with managerial talent的人不需要上课，B的意识的那些能skilled at problems 的人获得少的benefit from class
而原文还说了，那些上了课获得了idea的人在有问题的时候也能用idea解决问题
