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?

1. Because of the need to educate the public about its new models’ capabilities, Denoma’s advertising spending was higher than normal over the period.
2. For the period at issue, Denoma’s major competitors reported declines in revenue that were, in percentage terms, greater than Denoma’s.
3. A significant proportion of Denoma’s revenue comes from making components for other consumer-electronics manufacturers.
4. 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.
5. During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

为啥不是A是C呢？

A不也给出了其他解释么？

题目已经说了sales revenue from Denoma models actually grew，所以不管denoma的广告成本有多么高，Denoma model的利润是增加的。因此denoma业务的成本增加是不会对该公司电子消费产品业务的利润增长有直接影响。

C说明是是其他产品的利润决定了公司电子消费产品利润。如果只是denoma业务的利润增长，不会影响整体业务的利润增长。所以可以解释结论。

题目不是说的是零售商的利润提高了么？没说是Denoma公司的啊。

还在疑惑。

说了呀，their sales revenue from Denoma models actually grew。只是denoma型号产品的利润的增加了，但是的denoma公司的主要利润是来自为其他制造商提供组件。
