Suppose an ice cream store carries the following flavors: Apple (a), Brownie Batter (b), Death by chocolate (d), and Enigma flavor (e). Suppose that a friend of yours makes choices as follows:

- If available, they choose Enigma flavor and only enigma flavor

- If Enigma flavor is not available and death by chocolate is available, they pick Death by chocolate and only Death by chocolate

- If neither Death by chocolate nor enigma flavor are available, they would not reject any alternative

Question: What is the choice correspondence of this friend of yours (you may use the space below for your answer). Does it satisfy ? Does it satisfy ? For each of these axioms, if you answer yes, explain why; if you answer no, show an instance of the axiom's violation.
