please explain how you do part B
1. Pick an event. Read up online on something that sounds interesting or counter-intuitive (it doesn't have to be, it can be completely ordinary, like gold prices increasing, or whatever, but y'know, doing an interesting topic will probably be more exciting than something straightforward, and there's more to write about too).
2. Use that article as a starting point to discuss why the event occurred. e.g. The US Government prevented Microsoft from merging with Company X because it would have generated too much market power in the computer market (I recommend not copying this one, because it's an example in the textbook. You get my point though, right?). Use supply-demand curves wherever applicable (maybe not in the Microsoft example, but if you're analysing something that can be expressed using these curves, go for it!).
3. Submit on Monday, wait for your 30/30
