In Swartkans territory, archaeologists discovered charred bone fragments dating back one million years. Analysis of the fragment, 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 fire can heat wood to a range of temperatures that occur in campfires.

(C)The bond 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 500000

Years ago.

(E)The bone fragments were found in several distinct layers of limestone that contained primitive cutting toolls

known to have been used by early himinids.

answer is (E) ,WHY?

No other better choices.

A－比较present day的inhabitate，排除；

B－实际上是weaken了命题；

C－说的是骨头怎样，与用火无关；

D－很像，但是apart from与问题中的would together with the information above明显不匹配；

E－因为用树烧火，首先要用工具砍树，勉强算对吧。

能解释清楚一点嘛 谢谢

我觉得E选项的性质跟C是一样的, 都比较勉强, 请问有NN能将LAWYER的具体性与特殊

性的方法运用到此题目上吗?

OG的解释如下:

reasoning: the information that strengthens this argument iwill be about the subjects of the argument, not about tangential issues. in this case, the argument is about early hominid's use of fire. any physical evidence that links the early hominids to the charred bone fragments strengthens the argument. if these bone fragments where found in conjunction with some other evidence of the presence of early hoominids, then that evidence from the swartkans location could be used to support the claim that early hominids used fire.

d. the fragments date back one million years, so evidence from 500,000 years ago is irrelevant.

e. correct. this statement properly identifies evidence that links early hominids to these bone fragments and so strengthens the argument.

还是不懂啊. 为啥使用工具和用火有联系呢....
