Question

In a football field, what's typically present for every 10 yards?

a) Goal posts
b) Yard lines
c) Referee flags
d) Sideline markers

Answer 1

Every 10 yards on a football field, you will find yard lines. These are used to track ball position and are not affected by the units of measure, historic or current, as they are standardized.

Step-by-step explanation:

In every football field, you will find yard lines for each increment of ten yards. The field includes these marks to help players, referees, and fans keep track of the ball's position relative to the end zones and to measure the distance for a first down. Goal posts are located at the end of the field, sideline markers delineate the boundaries of the playing area, and referee flags are used to signal penalties; they do not occur at every ten-yard interval.

Therefore, the correct option in the final answer is yard lines.
