NFHS test help

#32. only adults may occupy the coaches box? I cannot find.

#49. ( Deadball Question) "The softball field includes an elevated cement step in front of each dugout"
Half the foot on deadball territory and the other half in the "air" over fair territory, has got me stumped. Does the other half of the foot have to be "touching" fair territory to be declared a live ball.

#57. In establishing the validity of a catch, the fielder must only hold the ball long enough to prove she has control.
I would say "true" to this question in a game situation. The definition in the book does not match the complete test answer?
