unfortunately we can't give you any help on this question, because the question itself is flawed in a way that you won't see on the GMAT. most of the problems with this one involve questionable grammar that among other things makes it difficult to determine exactly what the question is asking. please understand that using practice questions from dubious sources can actually hurt your performance, and be careful which problem sources you use..
