86. 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. Suprisingly, however, market researchers typically do not survey a new technology's potential byers, even though it is the buyers—— not the producers——who 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 accure largely to the producers, not to the buyers, of that technology.
(B) 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.
(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 positiond than its potential buyers to gauge how rapidly the new techology can be efficiently mass-produced.
这题选D，但我没明白E选项？OG 上的解释是“If developers of new technologies are no better at guaging how rapidly a new technology can be mass-produced , then all the more reason to survey potential buyers rather than the managers.”
