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 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 , 但是我觉得D 应该也是符合逻辑的, E 虽然说明了bone fragment 是被early hominids使用的工具, 但是并没有和火联系起来啊, D 就说明了是和fire 有关的工具啊? 作者: shaoyipeng 时间: 2010-7-19 06:39
D should not be right b/c it is talking about 500,000 years ago but not the original one millions years ago. So, it is not related.
E is correct b/c it says that the charred bone fragments existed at the same time with the early hominids. And since the fire that heated them up was just up to the scale of camp fire, then it must the early hominids who burned them.作者: stucashS 时间: 2010-7-19 19:54
