Heya! Is this a homework question? If so, we just want to remind you and any potential respondents, that our rules DO permit people to ask for help with their homework, so long as they are seeking clarification or resources, rather than the answer itself. This policy is looked at in depth in this META Thread.

Additionally, while our users may be able to give you a hand here, you may also like to check out our six-part series, "Finding and Understanding Sources", which should hopefully be handy as you continue your work.
