what was the effect of the three-field system
Three-field system Previously a "two field system" had been in place, with half the land being left fallow. With more crops available to sell and agriculture dominating the economy at the time, the three-field system created a significant surplus and increased economic prosperity.[1]
Three-point field goal For three seasons beginning in 1994–95, the NBA attempted to address decreased scoring by shortening the distance of the line from 23 ft 9 in (7.24 m) (22 ft (6.71 m) at the corners) to a uniform 22 ft (6.71 m) around the basket. From the 1997–98 season on, the NBA reverted the line to its original distance of 23 ft 9 in (22 ft at the corners, with a 3-inch differential). Ray Allen is currently the NBA all-time leader in career made three-pointers with 2,973.[33]
