Answer to second one-question test

[Bfair]

In checking something else I came across the following in NAPBL 6.4n and thought it would be of interest in this not so old thread:
"with runners on first and third, if a pitcher fakes a throw to third base and then throws the ball to first base, arm motion is not required by the pitcher in his fake to third"

I guess that, too, pretty well identifies that you can fake a throw (feint) without arm motion. I have still yet to see anything identified (other than opinion) that requires arm motion under ANY set of rules.
