Denoma, a major consumer-electronics maker, had a sizable decline in sales revenue for its most recent fiscal year. This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.
Which of the following, if true, does most to explain the apparently surprising result?
Because of the need to educate the public about its new models' capabilities, Denoma's advertising spending was higher than normal over the period.
For the period at issue, Denoma's major competitors reported declines in revenue that were, in percentage terms, greater than Denoma's.
A significant proportion of Denoma's revenue comes from making components for other consumer-electronics manufacturers.
Unlike some of its major competitors, Denoma has no lines of business outside consumer electronics to provide revenue when retail sales of consumer electronics are weak.
During the period, consumer-electronics retailers sold remaining units of Denoma's superseded models at prices that were deeply discounted from those models' original prices.
情景：Denoma报告说自己的销售收入下降了。但是，这个情况很不正常。这是因为，一个Denoma的零售商报告说它的收入上升了。
答案预估：
直接解释为何“Denoma报告说自己的销售收入下降了”即可。
选项分析：
A选项：由于需要让公众了解新产品的功能，Denoma的广告成本比正常的情况上升了。本选项讨论的是成本问题，而推理文段中讨论的是收入本题，两者没有任何联系（成本和收入无关，和利润挂钩），可以排除。
B选项：Denoma的竞争对手报告的收入降低的幅度比Denoma的降低幅度更大。谁的降幅大，并不能解释为什么下降。
C选项：Correct. Denoma收入的一大部分来自于给其它的厂商做配件。除掉零售收入外，还有给其它厂商做配件的收入。因此，由于其它的厂商收入都下降了，所以Denoma给其它的厂商做配件的收入降低了。本选项解释了推理文段的surprisingresult，可以保留。
D选项：不像某些Denoma的竞争对手，Denoma在零售收入较弱的时候没有其它的商业线来提供收入。本选项和(C)正好相反，指出了“零售收入”是足够的，没有其它收入来源可以提供。可以排除。
E选项：在这个时期，零售商将Denoma的过时的产品以一个打了很大折扣的价格卖出去了。本选项描述的是零售商的收入来自于哪里，并不能解释为什么收入会下降。
Denoma的销售收入最近几年下降了，但是surprising，retailers说近几年卖的Denoma电器销售收入上升了，尽管retailers整体的销售收入下降了。
是Denoma的销售收入和retailers销售的Denoma产品的收入的冲突，整体和样本的冲突。
解释该surprising fact的方式是说明样本不能够代表整体，及引入其他变量，"making components for other consumer-electronics manufacturers"，是其他制造商销量的下滑导致Denoma整体销售收入的下降，即使自己的产品卖的好也不足够改变现状。
