GMAT一道逻辑题
T-4-Q14 GWD-13-38
Frobisher,a sixteenth-century English explorer,had soil samples from Canada’s Kodlunarn Island examined for gold content.Because high gold content was reported,Elizabeth I funded two mining expeditions.Neither expedition found any gold there.Modern analysis of the island’s soil indicates a very low gold content.Thus the methods used to determine the gold content of Frobisher’s samples must have been inaccurate.
Which of the following is an assumption on which the argument depends?
A.The gold content of the soil on Kodlunarn Island is much lower today than it was in the sixteenth century.
B.The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.
C.The methods used to assess gold content of the soil samples provided by Frobisher were different from those generally used in the sixteenth century.
D.Frobisher did not have soil samples from any other Canadian island examined for gold content.
E.Gold was not added to the soil samples collected by Frobisher before the samples were examined.
我选的A,A为什么不对呢?

D.Frobisher did not have soil samples from any other Canadian island examined for gold content.
E.Gold was not added to the soil samples collected by Frobisher before the samples were examined.
我选的A,A为什么不对呢?
题目大意 测试 Frobisher的样本中高金含量,但当时并未发现金,现代科技也认为金含量高.说明测试该样本的测试方法不对.
这说明样本肯定是没问题的.否则无法得出测试方法不对的结论.因此选e e说样本并未添加金提高金含量,与样本正确同一道理.
a错误在,因为当时的矿井就没发现金,说明这跟时代无关.
b错误在无关内容.
c错误在无关内容.是否相同与是否正确毫无关联.
d错误在直接否认了样本本身,与样本没问题相违背.
再问： Modern analysis of the island’s soil indicates a very low gold content.
应该是现代测出含金量很低吧
再答： 哦咱打错了，是现代也认为含金低。笔误、笔误sorry
