你看看國外論壇的解釋～

Guys,

1. Evidence that it is likely that consumers will hear about new product announcements once they are made [choice B does exactly that]

这个和我上面8楼回复的好像一样？

文中的逻辑关系：如果customer听说要出new devise, 那么他们就会停止购买current devise.
结论：如果company要推出new devise，那么他们应该等current devise销量出现下降。
选项b如何make sense？media outlets report on the planned introduction of new devices，注意这里的主语是media outlets而不是company announce，所以这个选项并没有weaken文章中的结论。Media outlets report on the planned new introduction of new device -> customers hear the new device will be launched -> sales of the current devise will be declined -> ok, its time for the company to announce the upcoming of new device. 加强结论。

我明白啦~简化好这题的premise 和conclusion就好啦~认同8楼~
个人理解：
premise：Once consumers hear about the new device, they may stop buying the one currently on sale
conclusion: announcing new technology too soon after the introduction of a successful device can backfire

once they hear about that , they may stop; ( then, they know exactly that there will be new products from the Media outlets' report) So, they will not buy the old ones    以此来加强了结论
至于So后面的部分，是用一种目标-方案体现出了上面所述的关系，所以可以直接认为，上半部分已经体现出了作者的argument.
