Thank you for the opportunity to help you with your question!
Don't trust Studypool, they are a bunch of scammers. They stole me 160 $. I've worked 3 months providing high quality answers and still not beeing paid for some unknown and not precised reasons. Keep safe and go away from this website.
Please let me know if you need any clarification. I'm always happy to answer your questions.

Studypool's Notebank makes it easy to buy and sell old notes, study guides, reviews, etc.
