The history, role and purpose of VAT

Order Description
This is a GROUP work, and I will upload additional files, there are some instructions about this essay supported from our tutor, and there are four parts we need to write, and my part is the first and the fourth. And in my opinion, I think the first one is more important, so the first one will account for 70 percent of total words (around 1400-1500), and the fourth one accounts for 30 percent (around 600-700 words).
