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
E选项也太牵强了吧，有人类存在不一定就是用火的证明啊，不然“茹毛饮血”这个词是大风刮来的啊，鄙视GMAC。当然也欢迎大家鄙视我！！作者: sdcar2010 时间: 2011-3-26 22:32
The argument says the bone fragments could have been heated by campfires made from white stinkwood.
There are two possibilites: 1) those bone fragments were leftovers after hominids cooked the animals using campfire; 2) those bone fragments were from animals killed by natural fire.
E shows that hominids probably used cutting tools to deal with the meat.
Strengthener does not need to make the argument airtight. It only sheds more positive light on the argument and makes the argument more likely. That's why in the question stem, it says "provide the best basis for the claim" instead of "prove the claim."作者: leci 时间: 2011-3-26 22:58
非常感谢！ 要是您能用中文解释就更好了，呵呵！
接着问一步，文中“骨头碎片被烧的温度要低于campfire燃烧的温度”对于本题有什么意义？是否可以理解为：因为被烧温度低于campfire温度，所以骨头碎片不是人类用火所烧，而是自然火烧的呢。这样一来，岂不是跟答案反了？作者: sdcar2010 时间: 2011-3-26 23:02
