Final answer:
After a touchback in football, the team can put the ball in play anywhere between the hash marks on their 20-yard line.
Step-by-step explanation:
The question asks where a football team can put the ball in play after a touchback occurs. The correct answer to this question is b) Anywhere between the hash marks on their 20-yard line. Although there have been different standards in the past, today the length of a yard is standardly defined and can be seen on football fields everywhere. The consistent measurement of a yard ensures that when a football player moves the ball ten yards, this distance is the same whether they are playing in Los Angeles, Dallas, or Green Bay, ultimately resulting in a first down.
