GWD-12-Q22:
Denoma, a major consumer-electronics maker, had a sizeable 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?
A. Because of the need to educate the public about its new models’ capabilities, Denoma’s advertising spending was higher than normal over the period.
B. For the period at issue, Denoma’s major competitors reported declines in revenue that were, in percentage terms, greater than Denoma’s.
C. A significant proportion of Denoma’s revenue comes from making components for other consumer-electronics manufacturers.
D. 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.
E. During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.
Answer:请问这题为什么选C呢？

假设Denoma只有两个项目，那么总收入 = a项收入 + b项收入。总收入降低，a项收入提高，说明b项的收入剧烈下降了。

A 在谈论支出，跟营收没有关系的。
B 无关项，只讨论了其他竞争对手的情况
C 正确。这里Denoma的b项目是为其他厂商代工零件，因为其他厂商的营收急剧下降，导致了Denoma的b项也急剧下降。
D Denoma只有一个产品线。这个也可认为是无关项。
E 那个model是靠打折而火爆的。营收只是跟实际的售价相关，而非跟原始标价相关。
