Rookie Test Question #2 - 1 and 1

[mbloise]

Question:

A-1 is erroneously awarded a 1-1. A-1 makes the first and misses the second, which is rebounded by B-1 who passes to B-2 who scores. The error is now recognized before the ball is at disposal of team A. Official cancels, the free throw, counts B-2's basket and resumes play from the point of interruption. Is the official correct?

Answer: ???

I said yes, however the thing that I question is the counting of B-2's basket.

Thanks,
Mike
