In Swartkans territory, archaeologists discovered charred bone fragments dating back one million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood, the most common tree around Swartkans.

Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?

正确答案: E

不是bz,更不是nn,不过我也来试一下。看到问题,是support,找可以fill up推理gap的选项或非他因选项:

A)该树种现代人用来盖房子,unrelevant

B)森林大火可以达到试验中火的温度,weaken

C)考古学家把碎骨头拼成了几付动物骨骼,could be support, pay attention to "several"

D)原始人在500万年前是用火的,1 million year is earlier than 500 thousand, unrelevant

E)在烧焦的骨头里有明显的原始人用工具的痕迹,the bones were trimed by hominids, but not random bones burned by forest fire, correct

其实我做这题时在C和E里犹豫来着,但最后还是觉得E更support一些
