#24 - I believe is FALSE. 6.3.3 (b)..... the statement doesn't mention if CF's other foot is closer to the centerline than CB. What say you?
#34 - I feel this is also a FALSE statement because the libero is classified a "back row player", and as such, cannot set the ball using overhand finger action while on or in front of the attack line. 9.5.6 (b)
#42 - is FALSE as well. 9.5.1 (c)(1) defines "block attempt" as action without touching the ball and does not constitute a foul by a "back row player" when there was no contact with the ball.
Your interpretations MC?
