一道cr题

In Swartkans territory,archaeologists discovered charred bone fragments dating back 1million years.Analysis of the fragments,which came from a variety of animals,showed that they had beed 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 ture,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.

E.The bone fragments were found in several distinct layers of limestone that contained priimitive cutting tools known to have been used by early hominids.
C.The bone fragments were fitted together b the archaeologists to form the complete skeletons of several animals.
为什么选e 不是说要用头脑空白原则吗 cutting tools 和用火有什么关系？c不是可以说明样本比较充分从而加强吗

狒狒上课没有讲，我也不会

1。逻辑题哪怕一点点错误都是误导的。had beed heated(been).together b the archaeologists (by?)

2。C说的是人类学家做的事，与结论（骨头能证明人类用火）无关。E增大了人类用火的可能性（这些骨头和人类用的工具放在一起，不一定要CUTTING TOOL，别的人类用的器具也行，只要是人类独有的东西就行）

我知道啦
