GWD-12-Q29:
The Earth’s rivers constantly carry dissolved salts into its oceans.Clearly, therefore, by taking the resulting increase in salt levels in the oceans over the past hundred years and then determining how many centuries of such increases it would have taken the oceans to reach current salt levels from a hypothetical initial salt-free state, the maximum age of the Earth’s oceans can be accurately estimated.
Which of the following is an assumption on which the argument depends?
A.The quantities of dissolved salts deposited by rivers in the Earth’s oceans have not been unusually large during the past hundred years.
B.At any given time, all the Earth’s rivers have about the same salt levels.
C.There are salts that leach into the Earth’s oceans directly from the ocean floor.
D.There is no method superior to that based on salt levels for estimating the maximum age of the Earth’s oceans.
E.None of the salts carried into the Earth’s oceans by rivers are used up by biological activity in the oceans.
这题小弟选的E,答案给的A,小弟完全不理解啊？？？求各位帮助谢谢
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E.During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.
这题的答案是C,小弟选的E,不明白为什么不行？E中说那些零售商所销售的Denoma's model是以前留下来的（remaining),所以就不是在current period里从Denoma那里购买来的，所以说零售商的销售额上升了并不代表Denoma在当期的销售额上升了。不能这样理解吗？求大神指点！！谢谢
