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?

A.    If a new technology succeeds, the commercial benefits accrue largely to the producers, not to the buyers, of that technology.
B.    eople 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.
C.    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.
D.    The potential buyers for not-yet-available technologies can seldom be reliably identified.
E.    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.

答案是D，看不懂为什么，求解释。谢谢。

试identify新技术时，MR会survey开发新技术的公司经理们，因这些经理们对其技术的成功有利害关系，所以他们总是夸大新技术的潜力。
结论是：尽管希买家而非产品最终决定一个技术的商业价值，MR还是不会survey潜在买家
D因为潜在买家对于没有应用的技术没有可靠的identified。正好解释了为什么MR不survey潜在买家，是正确答案。

问题focus在为什么没有调查potential buyers
ABCE都跟potential buyers无关
