What is arcoss primarily used for?

• A. A defensive zone tactic
• B. The act of marking the opponent directly across on the other team before a pull
• C. A type of throw
• D. A celebration

Answer: (B)

The main idea here is what marking across means in Ultimate Frisbee. Across refers to the defender positioning themselves directly across from the thrower on the other team to apply immediate pressure and limit the throw options as the play begins, typically before the pull. This one-on-one marking across the thrower is a fundamental way to contest the handler and disrupt the offense right from the start. The other choices describe different concepts—zone defense, a type of throw, or a celebration—which don’t capture what marking across is.
