Hi! You seem new here, so I suggest checking out OpenStudy code of conduct. http://openstudy.com/code-of-conduct In there it states we cannot help you with quiz/test questions. Something you need to remember on here is, this is OpenStudy, not OpenCheat. :) We would love to help you study for a quiz, but we cannot help you on a quiz.

Thank you! Have a wonderful day.
