不是很理解的OG12版的一道题--大家指点

24. The Plexis Corporation, a leading computer chip manufacturer, is currently developing a new chip, which is
faster and more effi cient than any computer chip currently in use. The new chip will be released for sale in
twelve months. Plexis’ market research has shown that initial sales of the new chip would be maximized by
starting to advertise it now, but the company has decided to wait another six months before doing so.
Which of the following, if true, provides the Plexis Corporation with the best reason for postponing advertising
its new chip?

(A) Some computer users are reluctant to purchase new computer products when they are fi rst released.
(B) The cost of an advertising campaign capable of maximizing initial sales of the new chip would be no
greater than campaigns previously undertaken by Plexis.
(C) Advertising the new chip now will signifi cantly decrease sales of Plexis’ current line of computer chips.
(D) Plexis’ major rivals in the computer chip manufacturing business are developing a chip with capabilities
that are comparable to those of Plexis’ new chip.
(E) Taking full advantage of the capacities of the new chip will require substantial adjustments in other
segments of the computer industry

答案是C

文意：PLEXIS公司是电脑芯片的龙头制造企业，现在正研制一种比现用芯片更快更有效的新芯片。新芯片12月后将投入市场。公司的市场调查显示如果现在做广告，公司将在芯片最初投入市场时获得最大收益，但是公司已经决定多等6个月再做广告。下列那项如果真是，最能支持公司对于新芯片的决定？

A，一些电脑用户不情愿购买新的电脑芯片，当它们刚上市时（错，与文意无关，一些电脑用户不管喜不喜欢刚上市的芯片都与公司延后6月做广告无关。因为调查已经确定现在做广告才能在刚上市时获得收益最大化）

B，广告花费所产生的刚上市时的最大化收益并不比以前广告投入的多。（错，广告费并不比以前多，那么就是可以做广告咯，削弱了公司的决定

C，为新芯片做广告会大大减少公司现在售卖的芯片的销售（对，从公司整体来看，后面的新芯片不应该减少当前旧芯片的销售。如果做了广告，现在的销售量就少了，利润也少了。支持了公司6个月后才做广告的决定）

D，PLEXIS的竞争对手也在开发同样式的新芯片（错，既然如此，那更要现在打广告抢市场了。那么公司的决定被削弱）

E，要完全更好发挥新芯片优越性能需要电脑工业其它部门大量测评（错，新芯片优越性是顾客考虑的，公司目标是利润最大。如果现在广告利润最大，肯定会现在，所以此项与文章推论无关）
