I don't think you have to get material related to hughes. I think u need to relate it with how they may or may not be telling the truth.
I'm using Fulbright Scholars, and Your Paris, and i was thinking about how hughes is kinda lost, sounds like he doesn't know what he's talking about, questioning his credibility, and also can be ambiguous at times, leaving things open to interpretation where the responder may get the wrong idea. and something else...
Though, i'm not sure if this is any good, or if im clutching at straws, which i kinda am (like for all of english >_>...) or if someone could suggest something better, please do...
i seem to be inately bad at this subject, so, i wanna know if im headed in the right direction.
