Directiоns: Chооse the аppropriаte аnswer to identify the pattern or patterns in each reading. Football and rugby both involve two teams who try to score points by carrying a ball into an area at the end of the field. However, the two games differ in many ways. In football, each team has eleven players on the field. In rugby, there are fifteen players on the field. Foot-ball players wear protective helmets and pads. Rugby players wear no padding, although they can choose to wear a soft leather cap. In football, players can throw the ball to each other. In rugby, passes are illegal, and players must move the ball down the field by running with it or kicking it. When a football player is tackled, the game stops. Rugby, however, is a continuous game. A tackled player must immediately release the ball, and play continues. Rugby allows no time-outs either.
