正确选项怎么就回答问题啦？

逻辑题我是觉得都读得懂，但还是觉得很难，尤其是经常想不明白正确选项怎么就回答问题了？难道只是因为提到了文章讨论的东西吗？

When trying to identify new technologies that promise to transform the marketplace, market researchers survey the managers of those companies that are developing new technologies. Such managers have an enormous stake in succeeding, so they invariably overstate the potential of their new technologies. Surprisingly, however, market researchers typically do not survey a new technology's potential buyers, even though it is the buyers-not the producers-who will ultimately determine a technology's commercial success.

Which of the following, if true, best accounts for the typical survey practices among market researchers?

	If a new technology succeeds, the commercial benefits accrue largely to the producers, not to the buyers, of that technology.
	People who promote the virtues of a new technology typically fail to consider that the old technology that is currently in use continues to be improved, often substantially.
	Investors are unlikely to invest substantial amounts of capital in a company whose own managers are skeptical about the commercial prospects of a new technology they are developing.
	The potential buyers for not-yet-available technologies can seldom be reliably identified.
	The developers of a new technology are generally no better positioned than its potential buyers to gauge how rapidly the new technology can be efficiently mass-produced.

选D。我自己做的时候觉得这D是提到了buyers,围绕原文讲的，可是怎么就解释客户决定技术的成功与否，但是不调查客户？

我就是觉得连不上啊

前提：it is the buyers-not the producers-who will ultimately determine a technology's commercial success.
结论：market researchers typically do survey a new technology's potential buyers

因为有个however，我们就解释一下这个问题。相当于削弱结论。
D选项，那些潜在的购买者很难被identified。因为很难被identified，所以把survey做在他们身上是没有用的。所以削弱了结论。

这样楼主明白了嘛？
