32. Brandon believes that mice exposed to radiowaves will become strong. He decides to perform his experiment
by placing 10 mice near a radio for 5 hours. He compared these 10 mice to another 10 mice that had not been
exposed. He made sure to use the same breed of mice. His test consisted of a heavy block of wood that blocked
the mouse food. He counted how many mice were able to move the block of wood to get to the food.
