标题: 大全-C-6
6. In 1980, a Danish ten-øre coin minted in 1747 was sold at auction for $8,000. Eleanor Bixby owns another Danish ten-øre coin minted in 1747. When she puts it on the market next week, it will fetch a price over $18,000.
Which of the following, if true, would most weaken the conclusion drawn above?
(A) Since 1980, the average price for rare coins has increased by over 150 percent.
(B) There are only four coins like the one in question in the entire world.
(C) Since 1980, the consumer price index has risen by over 150 percent.
(D) In 1986, a previously unknown cache of one hundred coins just like the one in question was found.
(E) Thirty prominent, wealthy coin collectors are expected to bid for Bixby’s coin.
这道题的答案是D, 怎么也想不明白. 原文只是提到1980年的事情,又说现在EB这个人有个同样的coin,可是没有具体给出年代, 难道题中的那个EB的事情是发生在D中所提的1986之后的? 我这样理解对吗? 请高人指点迷津.

用排除法吧。而且也只有D才有可能使那个钱币贬值。

不明白D如何可以令钱币贬值？应该是升值把，80年是8000元， NEXT WEEK是18000元，明明NEXT WEEK的价值多了。

这个为什么选D？发现了未知的东东就令价值升高？

可能的同样藏品增加了，供给多了，所以价格应该下降，weaken

我想應該也是!!

注意Eleanor Bixby owns用的是现在时，表示E这个人现在有一个coin，并且next week准备出售。而不是1980年的next week。只有D最符合
