几经里有一道GWD的提干一样,就是部门经理缺少,但是选项都变了,填空。 是GWD的哪套里的 谢谢!!! 急!!! 下面是我找到的测黄金那题。 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.
