Describe the contract from last week (or describe a new contract if you don't remember) and describe 4 ways the contract can be discharged.
Here's an example:
Contract description: I agreed to teach this class.
1. Conditions changed - All electrical power in the world is gone
2. Material breach of contract - I never graded a quiz or test and didn't hand in any grades at the end of the semester
3. Mutual rescission - I don't teach, CWI doesn't offer the class, so everything is back to where it was before the contract
4. Bankruptcy - CWI goes bankrupt
