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?
(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.
(E) Gold was not added to the soil samples collected by Frobisher before the
samples were examined.
想請問這題混淆選項C要怎麼排除呢?
如果F的評估方法不一樣，不是可以當作assumption來support conclusion?
謝謝~~

1F：推 wakamala: 我覺得是質疑/討論題目，因為如果C是對的，表示題目說這 01/06 06:10
2F：→ wakamala: 份樣本的高含金量這句話是錯的。但E選讓題目敘述都正確 01/06 06:10
3F：→ wakamala: ，只是因為缺了e選的資訊，所以造成題目中敘述的狀況 01/06 06:10
4F：推 michaelmas: 與大眾評估的方法不一樣 不一定就是不準的 01/06 11:06
