后天考试，一道逻辑题求救

七毫米水果糖

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?

• ABecause of the need to educate the public about its new models' capabilities, Denoma's advertising spending was higher than normal over the period.
• BFor the period at issue, Denoma's major competitors reported declines in revenue that were, in percentage terms, greater than Denoma's.
• CA significant proportion of Denoma's revenue comes from making components for other consumer-electronics manufacturers.
• DUnlike 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.
• EDuring the period, consumer-electronics retailers sold remaining units of Denoma's superseded models at prices that were deeply discounted from those models' original prices.
• 答案是C，想不通的是E选项，打折了，revenue不就少了吗？

是不是因为superseded models的discount不能证明总revenue的减少，从innovative and popular models收入还是可以增加，结果是不确定的。但是C就说了是A significant proportion，可以比较有力的推断。

electronics retailers report that... sales revenue from Denoma models actually grew
答案E不对“consumer-electronics retailers sold remaining units of Denoma's superseded models at prices that were deeply discounted from those models' original prices.”
不管怎么卖的，提干已经说了retailers卖的revenue增长了。降价卖过气产品并不直接导致总体revenue.

C 对，因为指出了提干里的gap.  sales revenue 和electronics retailers reported sales revenue 不是同一回事，除非100%都是从electronics retailers卖的。C可以指出任何一个非electronics retailers卖的sales revenue,都可以解释。

同意。邏輯題常出的錯誤選項會僅針對premise做補充解釋，或者談論premise已經包含的事情，而沒有針對論點本身。也就是「前提之前」或「結果之後」，而不是討論因跟果之間這一段的關係。

这一题你需要personalize一下原文就比较容易选了。

加粗地方的意思就是说，厂家去年的收入降低了，但其实经销商们卖该厂家生产的Models的收入却是增长的，这里personalize之后，就能够predict到问题不出在下游销售端。

其实想清楚了没辣么复杂：
D的总收入是下降的，但是他的零售商的销售收入是提高了的，尽管销售量小了
这就说明（1）D的收入来源占比，除了卖给零售商retailer，还有别人，而别人这块的收入是下降的，而且这部分收入所占比重更大。（C选项提供一个“别人”：manufacturers）
（2）为什么会下降：manufacturer和retailer的隐含关系，retailer的销售量小了，进货就少了，供货的manufacturer自然收入就会下降，而D是manufacturer的manufacture，自然也会下降
