1. What is the main idea of "LangGraph for Stateful Agents: Modeling Loops, Forks, and Checkpoints"?

   1. LangGraph models agent state as an explicit graph with checkpoints; understand it to debug long-running agents you can stop and resume.
   2. Use AI as the final authority for the whole decision
   3. Avoid checking the answer once it sounds polished
   4. Focus only on speed instead of judgment

2. Which concept is most central to "LangGraph for Stateful Agents: Modeling Loops, Forks, and Checkpoints"?

   1. agents
   2. LangGraph
   3. state machines
   4. orchestration

3. Which use of AI fits this topic best?

   1. Substitute for production-grade workflow systems on safety-critical jobs
   2. Let the AI decide what matters without your review
   3. Express loops, forks, and human-in-the-loop steps as first-class graph nodes
   4. Use the answer before checking whether it fits the situation

4. Which limitation should you watch for in this topic?

   1. Express loops, forks, and human-in-the-loop steps as first-class graph nodes
   2. Explain the topic in plain language
   3. Organize a draft for human review
   4. Substitute for production-grade workflow systems on safety-critical jobs

5. What should a careful learner remember about "Checkpoint inspection drill"?

   1. Use AI to draft or organize ideas about LangGraph, then verify before acting.
   2. Skip the context so the tool can guess faster
   3. Treat the output as private even after sharing it online
   4. Use the answer without checking the source

6. You want to use AI after this lesson. What is the safest next step?

   1. Act immediately because the AI answer is written clearly
   2. Use AI for drafting and comparison, but verify before publishing or relying on it.
   3. Hide uncertainty so the final answer looks cleaner
   4. Use private or sensitive details before checking permission

7. How should AI output about LangGraph be treated?

   1. As proof that no other source is needed
   2. As a replacement for context, consent, or expert review
   3. As a draft or helper output that still needs human judgment and verification
   4. As something that becomes correct when it sounds confident

8. Name one way to verify an AI answer about LangGraph.

9. Which action would help you apply "LangGraph for Stateful Agents: Modeling Loops, Forks, and Checkpoints" responsibly?

   1. Eliminate the need for explicit error handling at every node
   2. Use the tool to avoid thinking through the tradeoff
   3. Keep going even if the output conflicts with a trusted source
   4. Persist state to a checkpointer for resumption after crashes or pauses

10. Which choice is a bad use of AI for this lesson?

    1. Eliminate the need for explicit error handling at every node
    2. Express loops, forks, and human-in-the-loop steps as first-class graph nodes
    3. Ask for a plain-language explanation of agents
    4. Compare the answer with a trusted source
