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 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！！

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."

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？

No higher than is not lower than. No higher than = equal to or lower than.

if categorize according to Lawyer theory, it's a "Support" model or an "Assumption" ?
thanks

这道题最简单的理解就是：
题目说骨头被烧只有2种情况：1.自然的火 2.人类用的火
E选项只是为了说明这“碎骨”跟“人”有关。至于是和人类的切割工具还是人类的武器或者别的什么人类的东西一起出土都没有影响，只需看到碎骨和人有关即可。
5个选项就会发现只有E提到了碎骨和人，所以就选这个。
不要去想选项中具体切割工具和骨头又有什么关系，是不是用来切肉吃，然后烤肉吃之类的，千万别去想，因为考试时没有这份精力和时间。
