 Q16:

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?

 

1. The gold content of the soil on Kodlunarn
                           Island is much lower today than it was in the sixteenth century.
2. The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn
                           Island.
3. The methods used to assess gold content of the soil samples provided by Frobisher were different from those generally used in the sixteenth century.
4. Frobisher did not have soil samples from any other Canadian island examined for gold content.
5. Gold was not added to the soil samples collected by Frobisher before the samples were examined.  answer:E  可以幫我解釋這題的意思嗎!!!謝謝

题目:
F 从K岛搞了一批土壤样本,因为样本含金量高.E一世资助了两次mining expeditions,但都没在该处发现黄金. 现代的分析显示K岛土壤的金含量很低,所以用来衡量F的土壤样本的方法不准确.

E: 在F的样本送检前,并没有在样本中人为的加入金子.

E:排除他因假设
