Moderator 'mathmale' here:

@dragonknight326 : Please post one question at a time, beginning now.

@SarahEZZMcK: If you provide direct answers without involving the person asking the question, you are clearly in violation of the Code of Conduct. Please stop now. Instead,
ask questions that may help that person find his/her own answers. for example, you might ask that person which of the possible answers could not possibly be right and then let him/her cross that possible answer out. Or you could refer him/her to a web site, a definition in a textbook or online, or whatever.
