Which of the following actions have already occurred on the Libero control sheet?

• A. #6 substitutes for #1; The Libero served in position IV for #22; Libero #9 replaced Libero #15; #5 substituted for #13.
• B. Only the Libero #9 replacement occurred.
• C. No substitutions have occurred yet.
• D. The Libero served in position IV for #22 and #5 substituted for #13.

Answer: (A)

The Libero control sheet logs every Libero-related action as it happens: when a substitution brings a new player in for a teammate, when the Libero enters or exits for a player, and even when the Libero serves in a given rotation (if your league rules allow it). Seeing multiple distinct entries means several Libero events have already occurred in this set. In this case, there are four separate actions happening—a substitution in for a player, the Libero serving in a specific position, a Libero replacing another Libero, and another substitution for a different player. That combination reflects the actual sequence recorded on the sheet. If only one action or none had occurred, the sheet would show only that single entry or be blank, respectively.
