A.Instrumental ties can develop even in situations in which people would normally not cooperate. B.Instrumental ties require as much emotional investment as expressive ties. C.Instrumental ties involve security, love, and acceptance. D.Instrumental ties should be expected to be significant. 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. 5.Which of the following statements about fractures and cut marks can be inferred from paragraph 4?
- 56 - A.Fractures and cut marks caused by right-handed soldiers tend to occur on the right side of the injured party's body. B.The right arm sustains more injuries because, as the dominant arm, it is used more actively. C.In most people, the left side of the body is more vulnerable to injury since it is not defended effectively by the dominant arm. D.Fractures and cut marks on fossil humans probably occurred after death Paragraph 4: How did those dense southern Maya populations deal with the resulting water problem? It initially surprises us that many of their cities were not built next to the rivers but instead on high terrain in rolling uplands. The explanation is that the Maya excavated depressions, or modified natural depressions, and then plugged up leaks in the karst by plastering the bottoms of the depressions in order to create reservoirs, which collected rain from large plastered catchment basins and stored it for use in the dry season. For example, reservoirs at the Maya city of Tikal held enough water to meet the drinking water needs of about 10,000 people for a period of 18 months. At the city of Coba the Maya builtdikes around a lake in order to raise its level and make their water supply more reliable. But the inhabitants of Tikal and their cities dependent on reservoirs for drinking water would still have been in deep trouble if 18 months passed without rain in a prolonged drought. A shorter drought in which they exhausted their stored food supplies might already have gotten them in deep trouble, because growing crops required rain rather than reservoirs. 6.What can be inferred from paragraph 4 about how residents of Tikal met their needs for water and food during most periods of drought? A.They depended upon water and food that had been stored for use during the dry season. B.They obtained drinking water and water for crop irrigation from Coba dikes. C.They located their population centers near a lake where water was available for drinking and watering crops. D.They moved locations every 18 months to find new croplands and water sources.
