1. What is the main advantage of a 2 million token context window in an AI model?

   1. It makes the AI run faster on basic tasks
   2. It enables the AI to learn new information permanently
   3. It guarantees the AI will always give correct answers
   4. It allows the model to process entire books or codebases in a single prompt

2. A developer wants to ask a question about a function at the very beginning of a large codebase. What should they watch out for?

   1. They should split the code into smaller files first
   2. Accuracy tends to drop at the very beginning and very end of long documents
   3. They need to add extra padding tokens
   4. The AI will ignore the beginning of the document

3. Which of these is the BEST use case for a long-context AI model?

   1. Generating random creative stories
   2. Asking questions that require information from across an entire 500-page PDF
   3. Translating single sentences between languages
   4. Writing a short email

4. A student pastes their entire 1,000-page research database into Gemini and asks a simple question about the first page. What does the lesson warn about?

   1. The context window is too small for this
   2. They need to pay extra for large documents
   3. Quality matters more than quantity — dumping junk hurts performance
   4. The model will refuse to process it

5. How can you test if a long-context model is accurately recalling information from a long document?

   1. Ask the model what color your shoes are
   2. Ask the model to summarize the entire document
   3. Give the model a math problem to solve
   4. Ask about a specific fact you know exists on page 800

6. The lesson describes long context as what kind of tool?

   1. A power tool to use when actually needed, not as a show-off
   2. A tool that works without any internet connection
   3. A tool that automatically fixes grammar mistakes
   4. A tool that replaces all other AI models

7. If you drop a 200-page PDF into Gemini and ask about facts from page 1, page 100, and page 199, what are you testing?

   1. If Gemini can edit the PDF
   2. Whether the model can accurately recall information from the beginning, middle, and end of a long document
   3. Whether the PDF is properly formatted
   4. If the model will become overloaded

8. What specific number of tokens can Gemini hold in its long-context version?

   1. 200 tokens
   2. 2 million tokens
   3. 20 million tokens
   4. 2 thousand tokens

9. A developer includes every document they can find, even irrelevant ones, when using long context. What is likely to happen?

   1. The model may perform worse because irrelevant content reduces quality
   2. The model will automatically filter out junk
   3. The context window will overflow and crash
   4. The AI will learn from the extra documents

10. Why might a fact on page 800 of a long document be harder for an AI to recall than a fact on page 50?

    1. Pages near the end are always more important
    2. Accuracy tends to drop at the extremes of very long context windows
    3. Page 800 has smaller font
    4. The model only reads the first 100 pages

11. When should you specifically consider using a long-context model like Gemini with 2M tokens?

    1. Only when writing fiction
    2. Only for math calculations
    3. Whenever you need any AI assistance
    4. When you need to ask questions about an entire large document or codebase

12. Which statement about long-context AI models is NOT recommended by the lesson?

    1. Focus on quality over quantity
    2. Test recall with known facts from different pages
    3. Use long context for every single prompt to show off
    4. Use it for whole-codebase questions or long PDFs

13. What happens to accuracy when you push a long-context model to its maximum limit?

    1. The model automatically summarizes
    2. Accuracy typically decreases at the extremes of the context
    3. The model becomes more creative
    4. The model learns faster

14. A company wants to analyze a 1,000-page technical manual. Which tool would the lesson recommend?

    1. A spell checker
    2. A video editing software
    3. A simple calculator
    4. A long-context AI model like Gemini that can hold the entire manual

15. The lesson compares using long context to a 'power tool.' What does this imply?

    1. It's powerful but should be used selectively for the right jobs
    2. It requires no skill to use
    3. It's dangerous and should be avoided
    4. It can only be used once
