Referee Quiz

[jeremy341a]

While looking at the quiz on referee.com I came across a couple of answers which puzzled me.

5. Which of these are examples of
incidental contact?
a. Contact that occurs
unintentionally in an effort by an
opponent to reach a loose ball.
b. Contact that hinders the
opponent from participating in
normal defensive and offensive
movements.
c. If a screen by a player without
the ball is set outside the opponent’s
visual field, the opponent makes
contact that displaces the screener
but the opponent attempts to stop
upon realization he or she has been
screened.
d. If a screen by a player is set
within the opponent’s visual field
and the opponent makes contact that
displaces the screener.

The answer key says A is one of the correct answers. Seems to me that just because the contact is unintentional doesn't mean that it is incidental. Seem more info is required.

Second one.

15. If a player (excessively) swings
his or her elbows and makes nonincidental
contact with an elbow to
an opponent’s head, what kind of
foul may result?
a. Common foul.
b. Intentional foul.
c. Flagrant foul.
d. Flagrant 1 foul
e. Flagrant 2 foul

The answer key says that choice A. is one possible answer. Since the player swings excessively isn't the only options B or C?
