Hello!
As much as I would love to help you, this is a project where no one can help you. You have to come up with your own answer. Writing is generally about expressing your thoughts based off of the information given. However, I can give you a few pointers to writing a successful paper!
1) In this circumstance, you don't want to give your opinion about shepherding, but rather give facts without being biased (think about a good reporter, they are supposed to give facts without showing preference to one side of the story).
2) Next, go through all of your sources and label anything mentioning your given topic. (like a detective!). I highly recommend using sticky notes.
3) Then read through everything that you labeled and write down key ideas and themes throughout your sources.
4) Then, just write down anything that comes to mind about the topic. You can edit later.
5) Make sure you do it in one sitting, so that you don't disrupt your train of thought.
Good luck! I wish you all the best on your project! Hope it goes well, and I hope I was able to help in some way. One of the best things to do when you are overwhelmed is to just sit down and write. That way you have something to work with, then you can edit accordingly.
