大全 section13-15

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.fficeffice" />

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) 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E。虽然其他明显不对，但是我从E里面也看不出any support for the evidence of human use of fire.     (难道说有cutting tools 就一定有using of fires, 好像没有这种必然联系吧。)

注意问题是下面哪个选项 together with the information above提供了以前人用火的证据：

题干说用火（ heated to temperatures ），结论说以前的人用火（the use of fire by early hominids），两者之间的GAP是early hominids的存在。E正好说明用火和early hominids同时存在，填补了GAP。
