Read the article and select the best answer. Article: Football is, I believe, the most popular game in England: one has only to go to the important matches to see _ . Rich and poor, young and old, one can see them all there, shouting for one side or the other. To a stranger, one of the most surprising things about football in England is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He will tell you who he expects will win such a match, and his opinion is usually as good as that of men three or four times his age. Most schools in England take football seriously-much more seriously than nearly all European schools, where lessons are all very important and games are left for the children themselves. In England it is believed that education is not only a matter filling a boy's mind with facts in the classroom: education also means the training of character; and one of the best ways of training character is by means of games, especially team games; where a boy or girl has to learn to work with others for his or her team, instead of working for oneself alone. The school therefore plans games and matches for its students. Football is a good team game. It is good both for the body and the mind. That's why it is every school's game in England.
