Test question help

[zac]

Just finished the test but could not find rule on two questions so thought I would ask the experts on the board. #94-"Basket interference may occur during a free-throw attempt." I can't see why not, but can't find the rule. Also, #62-"During free-throw attempts resulting from technical foul, substitutes may be made only after the final attempt has been converted". My original thought is that substitutes have to wait until both technical free-throws are attempted.

Thanks for the help and a good season to all!
