Bob and Jim once worked in the same factory .One day, Bob lent Jim ten dllars, but then Jim left his work and went to work in another town without giving back the money. Bob did see Jim for a year. And at that time he knew from another friend that Jim was in anther town and staying at a hotel(旅馆). So he went there to see Jim late in the evening. When he got to Ji room, he saw Ji shoes near the door.“Well, he must be in,” he thought, and knocked at the door. There was no answer. He knocked again, and said,“I know you are in, Jim. Your shoes are out here.”请帮忙给出正确答案和分析，谢谢！
