Correctable Error

[The_Rookie]

A1 is fouled with five seconds remaining in the second quarter. Team A is awarded a throw-in and A1 passes the ball inbounds to A2, the horn sounds ending the quarter. As officials enter the court from the half-time intermission, the scorer informs the Referee that A1 should have been awarded one-and-one bonus situation.

Ruling: Shoot 1+1 to start Q3 no players on line and throw in with AP at division line.

Modification: If A1 passes to A2 and A2 makes a 3 before the half ends, does the basket still count? Would A1 still get the 1+1 to correct the error?
