标题: [求助]大全-13-15 没人问过.

15.   In Swartkans territory, archaeologists discovered charred bone fragments dating back 1 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 thousand years ago.（E）


(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.



我搞不懂为什么是E.不是cutting tools 不见得就证明用过火啊. 可以做家具,盖房....

LET ME TRY IT.

问题问的是“the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?”关键词有bone fragments, use of fire  ,hominids

A.OUT OF SCOPE

B.OUT OF SCOPE

C.OUT OF SCOPE

D.500 thousand years ago用火不等于1 million years ago也用火

E.含有两个关键词bone fragments，hominids.

用排除法，但具体的逻辑关系还是不大清楚。

感激rabbit, 你的方法是有用的, 我也是对逻辑关系犯昏, 这题我重贴一下,看看斑竹们怎么说.

B是一个weaken，b说明有可能是forest fires，不能说是out of scope

UP！

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
