Quizzing Lady

This old lady who gives candidates coming across her quizzes is one of the examiners of the premilary phase of the 287th Hunter Examination. She blocks the way of Gon, Kurapika, Leorio and an unnamed candidate in a desolated alley near Dolle Habor when they are trying to get to Zaban City and asks them two dilemmatic quizzes which they have to answer in 5 seconds. The unnamed candidate gives her an answer and in return she shows him a wrong way, leading to him being devoured by some kind of predators. Gon, Kurapika and Leorio on the other hand can't give her any answer within the time limit, thus she shows them the right way, because not answering is the correct answer to the dilemma.
