Mary plays basketball and has been excelling in most areas of the sport, but when an opponent bumps into her, she almost always falls over. what skill should she improve to avoid this problem? speed, coordination, power, or balance

If she almost always falls over when someone bumps into her then she needs to improve her balance skill. Speed and power have nothing to do with it really, and coordination is just how well you can move two body parts at the same time, or have a good aim.

Maybe meditation,stress relievers,try to have quite time try to get school done on time and try to go to bed earlier
