Paragraph 4: Fractures and other cut marks are another source of evidence. Right-handed soldiers tend to be wounded on the left. The skeleton of a 40- or 50-year-old Nabatean warrior, buried 2,000 years ago in the Negev Desert, Israel, had multiple healed fractures to the skull, the left arm, and the ribs.




7. Which of the following statements about fractures and cut marks can be inferred from paragraph 4?
○
Fractures and cut marks caused by right-handed soldiers tend to occur on the right side of the injured party's body.
○
The right arm sustains more injuries because, as the dominant arm, it is used more actively.
○
In most people, the left side of the body is more vulnerable to injury since it is not defended effectively by the dominant arm.
○
Fractures and cut marks on fossil humans probably occurred after death.

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 righthander.
9. 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
