Question: Answer the following question given this paragraph: There are a variety of types of movable joints, which are illustrated in Figure below . The joints are classified by how they move. For example, a ball-and-socket joint, such as the shoulder, has the greatest range of motion, allowing movement in several directions. Other movable joints, including hinge joints such as the knee, allow less movement. Q: What type of joint has the greatest range of motion? Choices: - Hinge - Gliding - Pivot - ball-and-socket A:
Answer: ball-and-socket

Question: Answer the following question given this paragraph: Most geological activity takes place at plate boundaries. But some activity does not. Much of this intraplate activity is found at hot spots. Hotspot volcanoes form as plumes of hot magma rise from deep in the mantle. Q: Most geological activity takes place where? Choices: - high altitudes - ocean floor - center of plates - at plate boundaries A:
Answer: at plate boundaries

Question: Answer the following question given this paragraph: 34.6 High-temperature Superconductors Superconductors are materials with a resistivity of zero. They are familiar to the general public because of their practical applications and have been mentioned at a number of points in the text. Because the resistance of a piece of superconductor is zero, there are no heat losses for currents through them; they are used in magnets needing high currents, such as in MRI machines, and could cut energy losses in power transmission. But most superconductors must be cooled to temperatures only a few kelvin above absolute zero, a costly procedure limiting their practical applications. In the past decade, tremendous advances have been made in producing materials that become superconductors at relatively high temperatures. There is hope that room temperature superconductors may someday be manufactured. Q: Superconductors are materials with a resistivity of? Choices: - above zero - greater density - high magnitude - zero A:
Answer:
zero
