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 righthander.
According to paragraph 5, what characteristic of a Neolithic spoon would imply that the spoon's owner was right-handed?
Wear on its left side=rubbing on their left side
