A) In a separate section, identify the types of objects (classes) in your model. Each class description should include: a. A meaningful name and a brief (~1 paragraph) description of what it represents. Do not describe internal state or variables. (5 marks) b. A set of messages (0..*) that it can receive. Each message should include a meaningful name, and a brief (1-2 sentence) description of how the object responds to the message. Only messages required for the scenario below should be defined. (7 marks)

B) Provide a plain language description of what class instances you will need and how they will work together to represent the specific scenario described below. This will be similar to the florist example covered in class. Be sure that: a. There are no aspects missing in the scenario (i.e., that elements explicitly mentioned in the scenario are represented) (4 marks) b. The description is given using the object and message names provided in part (A) (4 marks)

Scenario to Model:

Pat is an astrophysicist conducting experiments on the International Space Station with crewmates Micah and Roshan, both aerospace engineers by training. While Micah and Roshan are busy in the Columbus European Lab, Pat takes a gorilla costume out of a personal locker, puts it on, gets inside a storage bag commonly used for supplies, and waits in the nearby Destiny US Lab. When Micah and Roshan enter Harmony Node 2 (adjoining both labs), Pat pushes out of the storage bag and careens toward them while making loud gorilla noises.
