请教 这道GWD 的题。

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.

Answer: b我e

我也觉得e不太对但是 题目不太明白 所以不知道哪个对。

请教高手帮助翻译一下什么意思？

e is the answer and if e fails ,the discrepence of the gold content of the two test can not be explained by that the mothod is inaccurate.

我怀疑我选的答案 是因为题目说is an assumption on which the argument depends?

e 有点点out of scope. 但当时我一点都不明白这道题的逻辑关系。 所以e可选 如果你也选的话，能不能给下你的解题过程 ，i mean, 这道题他在搞什么？我看不懂b 也不明白题目啥意思~~~

I choose E, the same as you.

If E can stands the point, it is the content itself not the method is inaccurate.
