i discovered that this problem is from "1000SC".
that's a banned source here, because it's a TERRIBLE source—nearly ALL the problems in that source (excepting only the ones stolen verbatim from GMAC sources) have very serious faults.
please do not post further problems from that source here (and, for your own good, don't study from that source!).
