I don’t know how to handle this Writing question and need guidance.

For a more clear understanding, I will upload as many details as I can. This is an research essay with 1500 words minimum requirement and many multi-model evidences. I have already written an rough outline for the essay about 700 words. You can modify on it or start over. My main thesis is that trade has caused a significant loss in manufacturing jobs in the US, and manufacturing job loss is a big problem in US society. You will find evidences to prove it is a big problem and show how trade or globalization related stuffs actually caused it. Graphs as evidence is necessary in this assignment.
