Football teams have the option of trying to score either 1 or 2 extra points after a touchdown. A team can get 1 point by kicking the ball through the goal posts or 2 points by running or passing the ball across the goal line. A team makes zero points if either attempt fails. The kicking distance required for a one-point conversion was increased starting with the 2015 season. Complete parts (a) through (d) below.
