Paragraph 5：Tools themselves can be revealing. Long-handed Neolithic spoons of yew wood preserved in Alpine villages dating to 3000 B.C. have survived; the signs of rubbing on their left side indicate that their users were right-handed. The late Ice Age rope found in the French cave of Lascaux consists of fibers spiraling to the right, and was therefore tressed by a right-hander.
In paragraph 5, why does the author mention the Ice Age rope found in the French cave of Lascaux?
○ As an example of an item on which the marks of wear imply that it was used by a right-handed person
○ Because tressing is an activity that is easier for a right-handed person than for a left-handed person
○ Because the cave of Lascaux is the site where researchers have found several prehistoric tools made for right-handed people
○ As an example of an item whose construction shows that it was right handed made by a right-person
该题通过题目中的定位词很容易定位到段落的最后一句。不难发现，最后一句中并没有类似于“for example”或“for instance”这种表达，证明有可能是属于例子与概述合二为一的情况，即例子与概述位于同一个复合句中。就本题而言，最后一句中逗号后面的部分“and was therefore tressed by a right-hander”即为答案所在地。故本题的答案为第四个。
