Question Stats:

88% (02:07) correct 13% (01:34) wrong based on 8 sessions
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.

(A) Since 1980, the average price for rare coins has increased by over 150 percent.
>> This will strengthen the argument that says the price will be more now.
(B) There are only four coins like the one in question in the entire world.
>> Supports. If there are only 4 then for sure this coin will bid for more price.
(C) Since 1980, the consumer price index has risen by over 150 percent.
>> Supports. Because the consumer price is incresed, the coin value also increases.
(D) In 1986, a previously unknown cache of one hundred coins just like the one in question was found.
>>Weakens the argument. If there are hundred more coins just like this, this might not be the rare coin and so the bid can not be so high.
(E) Thirty prominent, wealthy coin collectors are expected to bid for Bixby’s coin.
>> Supports. If a wealthy coin collector bids for this coin, can bid more.

Still option D is inconclusive . the para never says that the coin is a rare one. it is however the LEAST BAD answer
the question is a bad one

Expert's post
This is one of those poorly designed CR questions that ask you to weaken a 'conclusion' which isn't a conclusion at all: there's no argument in the passage, and there is thus no logical basis for the statement "it will fetch a price over $18,000." in the first place. While I agree that D is the only reasonable answer here, it's a bad question. Where is it from?
