Consider a professor talking about an assignment:
Professor: Now I know some of you won’t be happy about this, but your presentations will be due next Thursday. Your presentations must be made on a data show, have details and examples about how the lakes were formed, and show images and photographs. You should collect data about the saline content. Remember, this is a group assignment, so don’t bite off more than you can chew. Spread the work around.
What is the professor mean when she says, “bite off more than you can chew”?
