5 次の英文を読んで、後の問いに答えよ。 In the "New England winter of 1891, it was too cold to "exercise outside. James Naismith, a Canadian college teacher, wanted to give his students a game to play inside. He tied two fruit baskets to the walls of the school's gym. Then, he gave the young men a soccer ball to throw into the baskets. At first, the students got too excited at the new game, and they began hurting each other. So James "created some rules. For example, he said that the players could not push or hit each other. He also made another important change Because he was tired of taking the ball out of the baskets after every score, he cut holes in the bottom of the baskets. Then he made a list of 13 simple rules and called the new game "basket ball." James shared the rules with other teachers. Basketball soon became popular in North America because it was fun, easy to learn, and could be played anywhere. Both boys' and girls' basketball teams began playing all over America and Canada. Basketball has become one of the world's most popular sports, but even now the 13 rules from 1891 are part of the game.
