Help with my Project?

Well I have a project due in World History.
And here what it is on.

Period 2: Illustrate and discuss the global economic and political connections of multinational corporations. (The United Nations)

Now, I have a basic understanding, but would anyone like to link me or provide me with information I could use to verbally present this? I don't COMPLETELY understand what it's asking. ...and it's due tomorrow.

Doesn't have to be but about 2 minutes long and I have to create a diorama with it.

Have you tried using google?

Yes but I'd like to hear it from another persons pov, that's on these forums -.-

Multinational. So talk about OPEC or NATO. The countries in each organization, respectively, share the same political and economical views.
