E1) I have a three-year-old friend. He has a lot of toy cars to play with. Playing with him once, I divided the cars into two sets. One set was more spread out and had 14 cars in it. The other set had 15 cars, but they were placed more closely. He had the choice of taking the set with more cars. He made the correct choice. From this, which of the following statements would you deduce? What are the reasons for your choice?
