为了加深印象，自己敲一遍。
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 500000 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.
XDF老师是这么讲的1.cbf:1000000 2.cbf---stinkwood结论：cbf作为人用火的证据
要让人与木头发生关系.cbf亦是早期人类使用的cutting tools.
中间那段关于温度的描述不大明白，整个链条怎样的呢？

122.The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.
Which of the following, if true, most strongly supports the hypothesis?
A.Bone flutes were probably the only musical instrument made by Neanderthals.
B.No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite.
C.The flute was made from a cave-bear bone and the campsite at which the flute fragments was excavated was in a cave that also contained skeletal remains of cave bears.
D.Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.
E.The cave-bear leg bone used to make the Neandeerthal flute would have been long enough to make a flute capable of playing a complete diatonic scale.
三个数字3，6，7之间有什么关系么？这个题整个是什么意思呢?
