Answer the following question given this paragraph: Kinetic energy is the energy of motion. Any object that is moving possesses kinetic energy. Baseball involves a great deal of kinetic energy. The pitcher throws a ball, imparting kinetic energy to the ball. When the batter swings, the motion of swinging creates kinetic energy in the bat. The collision of the bat with the ball changes the direction and speed of the ball, with the idea of kinetic energy being involved again. Q: What energy is the energy of motion? Choices: - optimal - potential - thermal - kinetic A:
kinetic

Answer the following question given this paragraph: A stroke occurs when a blood clot blocks blood flow to part of the brain. Brain cells die quickly when their oxygen supply is cut off. Therefore, a stroke may cause permanent loss of normal mental functions. Many stroke patients suffer some degree of paralysis, or loss of the ability to feel or move certain parts of the body. If medical treatment is given very soon after a stroke occurs, some of the damage may be reversed. Strokes occur mainly in older adults. Q: What medical emergency occurs when a blood clot blocks blood flow to part of the brain, causing death of brain cells? Choices: - cardiac arrest - epileptic seizure - heart murmur - stroke A:
stroke
