Occasionally one can determine whether stone tools were used in the right hand or the left, and it is even possible to assess how far back this feature can be traced.In stone tool making experiments,Nick Toth, a right-hander,held the core (the stone that would become the tool) in his left hand and the hammer stone in his right. As the tool was made, the core was rotated clockwise, and the flakes, removed in sequence, had a little crescent of cortex (the core's outer surface) on the side. Toth's knapping produced 56 percent flakes with the cortex on the right, and 44 percent left-oriented flakes. A left-handed toolmaker would produce the opposite pattern. Toth has applied these criteriato the similarly made pebble tools from a number of early sites (before 1.5 million years) at Koobi For a, Kenya, probably made by Homo habilis. At seven sites he found that 57 percent of the flakes were right-oriented, and 43 percent left, a pattern almost identical to that produced today.

11. What was the purpose of Toth'stool making experiment described in paragraph 6?
○To shape tools that could be used by either hand
○Toproduce replicasof early tools for display in museums
○Toimitate the productionof pebble tools from early sites
○To determine which hand made the early tools
答案D。原文说的是“can determine whether stone tools were used in the right hand or the left"够确定到底是哪只手用了这个工具，而答案说的是“早期的工具是哪只手做的”。意思不一样了啊，我就不懂为什么选D了，虽说其他选项也不对。。。

你看错的地方,所以这题才会错的..作者修辞目的题,问的不是文章内容,是问为什么要写这个例子,所以看例子
Toth's knapping produced 56 percent flakes with the cortex on the right, and 44 percent left-oriented flakes. A left-handed toolmaker would produce the opposite pattern.
这一句是实验例子出现,所以要看这个例子最后讲了什么
At seven sites he found that 57 percent of the flakes were right-oriented, and 43 percent left, a pattern almost identical to that produced today
这个实验最后证明了这个现象,所以是属于典型的例子证明观点的题目,
D选项刚好是这样
