13.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 fragmentsare evidence of the use of fire by early hominids?
(A) The white stinkwood tree is used for building material by the present-day nhabitants 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.
疑问:怎么感觉文章、题目、和选项几乎没有联系?
Background:The charred bone fragments dated back 1M years. Premise: The fragments indicated that it was heated at temperature no higher than those stink wood. Conclusion:Charred bond fragments are used by earlier hominids. 这样的话,我在没有看选项之前,我会想到一定会有个什么联系是关于早期人类和fragments的,以为他们要用火的嘛!然后看选项: (A) The white stinkwood tree is used for building material by the present-day nhabitants of Swartkans. --〉无关!这种stinkwood tree是不是用来做buidling material和我们的结论无关! (B) Forest fires can heat wood to a range of temperatures that occur in campfires. --〉forest fires可以烧木头,这不就是说和fragments没关系了吗? (C) The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals --〉这些fragments最后可以拼成动物的骨架也无关! (D) Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500,000 years ago. --〉早期人类使用火在50万年前,和我们的1M years时间不吻合,而且基本上不起到任何support作用。 (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. --〉这些bone fragments被发现在大理石的好几层layer中,而这个大理石显示了早期人类利用cutting tools的痕迹。这个结论明显将conclusion和premise直接联系起来了。 |
