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?


(A) The white stinkwood tree is used for building material by the present-day inhabitants of
Swartkans.

B
Forest fires can heat wood to a range of
temperatures that occur in campfires.

C
The bone fragments were fitted together by
the archaeologists to form the complete


skeletons of several animals.

D
Apart from the Swartkans discovery, there is reliable evidence that early hominids used
            




fire as many as 500,000 years ago.

E
The bone fragments were found in several distinct layers of limestone that contained

primitive cutting tools known to have been used by early hominids.



答案是E , 但是我觉得D 应该也是符合逻辑的, E 虽然说明了bone fragment 是被early hominids使用的工具, 但是并没有和火联系起来啊, D 就说明了是和fire 有关的工具啊?

D should not be right b/c it is talking about 500,000 years ago but not the original one millions years ago. So, it is not related.

E is correct b/c it says that the charred bone fragments existed at the same time with the early hominids.  And since the fire that heated them up was just up to the scale of camp fire, then it must the early hominids who burned them.

始终没有看懂E选项和火有什么联系,请NN解答.

这一题确实很诡异,我想了很久,不知道对不对:

题干里面有个很关键的部分是说研究那些烧焦的骨头发现烧那些骨头的温度不高于实验中的篝火的温度,这句话隐含着森林自然大火的温度要高于篝火的温度,因此可以推断出那些烧焦的骨头一定是人烧的,那么接下来只需要证明烧骨头的人是早期原始人类而不是后来的人干的,E答案用了早期原始人类使用的工具将烧焦的骨头和早期原始人类在时间上联系起来了,于是可以证明烧骨头的人是早期原始人类干的。

如果我的分析是正确的,那么这道题真的很有难度,起码2分钟要想出来答案很难

明白了,结论要求"evidence of the use of fire by early hominids",E正好证实了fragments used by early hominids
