NFHS Exam Rule Reference (Question 62 & 66)

[U-Cant-C-Me]

I have taken the 2009-10 NFHS Part 1 Basketball Rules Examination and I'm having a problem finding the rule references for a couple of questions. The two questions are:

62. During free-throw attempts resulting from a technical foul, substitutions may be made only after the final attempt has been converted.

66. It is permissible to withdraw a player before the clock starts following his or her substitution into the game.

I am not looking for the "True-False" answer but I would like where I can find the rule reference for these questions whether it be in the NFHS Rule Book or Case Book.
