Dude this isn’t hard. It’s your assignment, and I’m not taking points here or saying random things, but this is the equivalent of cheating. All they’re asking is for you to be creative and finish the story. They don’t want to see what a random person in the internet knows, they want to see what YOU know. You can do it, just put your head to it and be creative :D
A commission is where the artist gets paid to create art and a patronage is when the artist gets financial support through other people to provide these artworks.
