1. What happens to an AI agent's information by default when you start a new conversation or session?

   1. The agent forgets everything from previous sessions
   2. The agent only forgets minor details
   3. The agent keeps all information but in a different format
   4. The agent remembers everything but cannot use it

2. What is the simplest infrastructure-free solution for giving an AI agent memory across sessions?

   1. A cloud storage service with an API
   2. A vector database with embeddings
   3. A dedicated SQL database server
   4. A simple text file like memory.md that the agent can read and write

3. Why is memory.md called the 'duct-tape MVP' of agent memory?

   1. It's the most advanced and professional solution available
   2. It requires special expensive hardware to function
   3. It's a quick, simple fix that works surprisingly well before needing fancier solutions
   4. It was the first memory solution ever invented for AI

4. What two capabilities must a memory system have for an agent to remember information across sessions?

   1. Format the memory file and validate its contents
   2. Delete old memory and encrypt new memory
   3. Read existing memory and append new information to it
   4. Copy memory between files and compress it

5. If an AI agent learns during a conversation that the user prefers dark mode, where should it store this information?

   1. In the agent's code as a hardcoded variable
   2. In a temporary cache that clears when the session ends
   3. In the agent's system prompt only
   4. In the memory.md file so it's available in future sessions

6. What does the term 'persistence' mean when discussing AI agent memory?

   1. The ability to retain information across different sessions or runs
   2. The speed at which information can be retrieved
   3. The total amount of information that can be stored
   4. The security level of stored information

7. Which tool would you add to an agent to let it store new facts it learns during conversation?

   1. appendMemory (or writeMemory) to add new information
   2. formatMemory to clean up the file
   3. deleteMemory to remove old information
   4. readMemory to recall previous information

8. If an agent needs to recall what happened in a previous conversation, what should it do first?

   1. Search the internet for relevant facts
   2. Make guesses based on context
   3. Read the memory.md file to access stored information
   4. Ask the user to repeat everything

9. Why might a developer choose memory.md over a database for simple agent memory needs?

   1. It stores data more quickly than databases
   2. It can hold more information than databases
   3. It provides better security than databases
   4. It requires no database infrastructure—just a plain text file

10. What 'state' does a simple memory file help an agent maintain?

    1. Information about the user, project, and preferences that persists over time
    2. The network connection status
    3. The error and exception state
    4. The current computational processing state

11. After two separate sessions with memory tools, what should an agent be able to do?

    1. Predict what will happen in the next session
    2. Only function in the most recent session
    3. Recall information learned in the first session during the second session
    4. Store more information than a database can handle

12. What is the minimum number of distinct memory tools needed for basic cross-session memory?

    1. Four tools for maximum memory functionality
    2. Three tools for reading, writing, and deleting
    3. One tool that does everything
    4. Two tools—one to read and one to write/append

13. Why is having 'goldfish-level memory' (remembering briefly) better than zero memory for an AI agent?

    1. Goldfish are actually very intelligent creatures
    2. Even brief retention allows continuity and context across interactions
    3. It makes the agent appear more human
    4. It costs less to implement than real memory

14. In the example from the lesson, what specific information did Claude remember across sessions using memory.md?

    1. Its own source code
    2. The user's name from previous sessions
    3. Technical documentation it had read
    4. The entire conversation word-for-word

15. What type of file is memory.md?

    1. An encrypted file that needs a password
    2. A video or image file
    3. A simple Markdown text file readable by any text editor
    4. A binary database file requiring special software
