Hahaha, some of you guys are funny. chambers already said not to post that it's common sense or that an blank answer is not the correct answer. Some of you really need to read. Anyways, chambers, it's already been stated, but rule #4 just killed your argument, you just can't get around it.

And....one other guy said this...and he just hurt your argument too. You said that you got the rule not explicitly stating that a blank answer is incorrect from the original source (the manga). However, that is not the original source, the original source is the manga in Japanese. You can't trust the translators for perfectly structuring the sentence exactly how the writers meant it....so really, you're basing your argument on a potential translation error. Good going.

Well then, I can't believe I'm actually contributing to this thread.
