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，OG的解释是说：This information links early hominids to these bone fragments and so strengthens the argument.
但是我认为E选项中的primitive cutting tools 与 using fire 无关，原始人可以cut and eat 生肉啊，不一定需要火烤熟啊。
求助，这个选项应该怎么理解啊？ 作者: 轩辕aa 时间: 2017-7-12 23:07
逻辑要证明charred bone 和 hominids有关系
所以人类工具和charred bone 一起发现时
能证明bone和人有关系
至于cutting 不cutting不重要作者: Fiona09 时间: 2017-7-13 10:10
跟工具一起找到，为人类活动提供了证据。说明不是被自然大火烧的，而是跟人类活动联系在一起的。
