 阅读理解Like many other five-year-olds, Jeanie Low of Houston, Texas, would use a stool (凳子) to help her reach the bathroom sink. However, the plastic step-stool she had at home was unstable and messed up the small bathroom shared by her whole family. After learning of an invention contest held by her school that year, Jeanie resolved to enter the contest by creating a stool that would be a permanent fixture in the bathroom, and yet could be kept out of the way when not in use.Jeanie decided to make a stool attached to the bathroom cabinet door under the sink. She cut a board of wood into two pieces, each about two feet wide and one foot long. Using metal hinges ( 铰 链 ), Jeanie attached one piece of the wood to the front of the cabinet door, and the second piece to the first. The first piece was set just high enough so that when it swung out horizontally from the cabinet door, the second piece would swing down from the first, just touching the ground, and so serving as a support for the first piece of the wood. This created a convenient, strong platform for any person too short to reach the sink. When not in use, the hinges allowed the two pieces of wood to fold back up tightly against the cabinet, where they were held in place by magnets (磁铁). Jeanie called her invention "the Kiddie Stool".Jeanie's Kiddie Stool won first place in her school's contest. Two years later, it was awarded first prize again at Houston's first annual Invention Fair. As a result, Jeanie was invited to make a number of public appearances with her Kiddie Stool, and was featured on local TV as well as in newspapers. Many people found the story of the Kiddie Stool inspiring because it showed that with a pair of observant eyes, anyone can be an inventor. （1） According to the passage, why did Jeanie Low invent the Kiddie Stool?
