practice test questions (NFHS)

[FLRookie2003]

My local association gave a practice test (NFHS). I disagreed with some of the answers and am curious as to the opinions of the board.
==================================================
1-Q. (T/F) Following a touchdown, the clock shall start next on the kick-off.
A. I say True but they said False
(Perhaps bad wording as I consider the free-kick play as a whole the "kick-off"...the clock starts during the play but not at the kick but when B first touches the ball, if at all.)
==================================================
2-Q. (T/F) A false start can only be committed by the offense.
A. I say True but they said False
(7-1-7 "by A", but no mention of "B")
Side-question: can K commit a false start (on a kick-off)? (apparently not per the rule)
==================================================
3-Q. (T/F) No foul can occur that takes a down away.
A. I say True but they said False
(Perhaps bad wording...no foul takes a down away but it can be the loss of down, but that is the right to REPLAY a down.)
==================================================
4-Q. (T/F) Holding is always a 10 yard penalty enforcement regardless of where the foul occurred.
A. I say True but they said False
(Unless the spot of holding was inside team A's 20 then half the distance to the goal line...or in the B's end zone by A safety. Holding is a "10 yard penalty", but perhaps the enforcement eludes to the fact that inside the 20 less than 10 yards will be marked off or safety. 9-2-1c, 9-2-3d)
==================================================
5-Q. (MC) On an extra point attempt, the umpire notices that all players on the line have interlocked legs. Which of the following occurs:
a. Live ball foul and five yard penalty.
b. Dead ball foul and five yard penalty.
c. Live ball foul and fifteen yard penalty.
d. none of the above.
A. I say D they said B.
("On an extra point attempt," implies live ball to me...and it's a 10 yard penalty. 9-2-16)
