Which is not true about first a first down? The offense gets four more changes each time they get one first down. The offense gets four chances to get a first down. The defense gets only one try to get a first down. The quarterback and running back are both on the side trying to get a first down.

The defense gets only one try to get a first down.

Explanation:

The first down is the down in a series of four downs in which the offense team is expected to make a 10-yard gain or release the ball to their opponents. The four series of downs are identified as the first, second, third, and fourth downs.

The third option is not correct because when the defense team now has a chance at the ball, they switch sides and then become the offense team. So they would have the adequate number of chances expected of an offense team to get a first down.

it's false.
