Hello there. Unfortunately we have had to remove your question as it looks like it may be a homework question. A couple of things to keep in mind about this: 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. Also: Sometimes flairs can be reluctant to answer a question that looks like homework, because they don't want to be involved in plagiarism (and sadly, yes, there are those who plagiarize reddit comments).

But, that all said, many of our users do enjoy helping out with suggestions for resources and further reading. Can you tell us what you've researched so far, what resources you've consulted, and what you've learned? If that doesn't work, you can also consider asking the helpful people at /r/HomeworkHelp. If you edit your post to be in compliance with our requirements for homework related questions, which are explored in more detail in this META Thread, we would be happy to restore it.

Additionally, we would highly suggest that you check out our six part series on 'Finding and Understanding Sources', which might prove to be useful in your research.
