II. Read the following text and do the tasks below. Water rugby became the most popular of water sports, but somehow the water polo name became a popular name for it. As played in England, the object of the game was for player to touch the ball, with both hands, at the goal of the pool. The goaltender stood on the poll deck, ready to dive on any opponent who was about to score. Water polo quickly became a very rough sport, filled with underwater fights away from the ball, and it wasn’t unusual for players to pass out for the lack of air. In 1877, the sport was tamed in Scotland by the addition of goalposts. The Scots also replaced the original small, hard rubber ball with a soccer ball and adopted rules that prohibited taking the ball under the surface or, tackling a player unless he had the ball. A.
