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 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 samples collected by Frobisher before the samples were examined.

F是个16世纪
英国探险家,从加拿大K岛拿回土壤样本检测金含量。因为测出金含量高,伊丽莎白一世资助了两个开矿队。两个开矿队都没有找到金子。K岛的土壤分析表明金含量低。因此用来测F样本金含量的方法不精确 假设题 A. K岛的金含量现在比16世纪低;削弱,方向反,排 B. 两个开矿队没有开采K岛的同一区域;无关,排 C. 用来测F样本的方法和16世纪其他方法不同;无关比较,排 D. F没有从其他岛上取样本来测金含量;其他岛,跳出范围,排 E. 在样本检测前金子没有被加入样本;取反即有金子加入样本,测出金含量高不能说明测量方法不精确,取反削弱结论,正确
