When you need to write an essay like this, you should turn to a librarian for help, not just anyone on YA.
Your first paragraph will tell you what the three body paragraphs have to cover. You need to get information about the Industrial Revolution (good info; not whatever you find floating around the Web). Then you'll see how you should write this.
You're not sure what to write because you don't have the information you need.
Edit: xbby, it's pretty funny that you're writing on a mass-produced computer about how bad the Industrial Revolution was.
