Which of the following is an advantage of a brace formation?

The advantage of a brace formation is primarily centered around creating an effective barrier against opponents. In roller derby, a brace formation typically consists of two skaters maintaining close proximity to each other while forming a wall. This structure is effective because it limits the movement of opposing players, making it more difficult for them to break through and reach the jammer or disrupt the team's play.

By effectively positioning themselves in a brace, skaters can use their bodies to absorb hits, protect the jammer, and maintain control over the track, which is essential for both defensive and offensive maneuvers during the game. This cohesive setup not only strengthens the team's defensive capabilities but also allows the skaters to maintain a strategic position on the track.

While other options address various aspects of gameplay, they do not encompass the primary purpose of the brace formation, which is centered on defense and controlling the flow of the game against opponents. The formation does not inherently increase scoring opportunities or speed, nor is it exclusively focused on offensive tactics, making the option about creating a barrier the most accurate in terms of its primary advantage.
