1. What does AI use to see pictures instead of having real eyes?

   1. Human helpers who describe the photos
   2. Numbers in a giant grid
   3. A tiny camera inside the computer
   4. A robot that looks at the screen

2. What is a pixel?

   1. A pattern that AI uses to recognize objects
   2. A box that appears around faces on your phone
   3. A special kind of AI that looks at photos
   4. A tiny dot of color that makes up a digital picture

3. If you zoom in really close on a photo on your tablet, what will you eventually see?

   1. The word 'AI' hidden in the picture
   2. Tiny colored squares (pixels)
   3. A completely black screen
   4. Numbers written in tiny text

4. How does AI recognize that a picture contains a dog?

   1. By asking a person to look at the picture
   2. By finding number patterns it has learned that match dogs
   3. By remembering every single dog photo ever taken
   4. By using a magnifying glass to see details

5. Why can AI sometimes mistake a small dog for a blueberry muffin?

   1. AI has eyes just like humans do
   2. The number patterns for both can look similar to AI
   3. AI purposely makes this mistake for fun
   4. The muffin is actually a dog in disguise

6. What happens when AI looks at a photograph?

   1. It sends the picture to another computer to think about
   2. It turns the picture into a giant grid of numbers
   3. It prints out the picture to look at it
   4. It zooms in very close to see every detail

7. What is the term for when computers look at pictures and figure out what is in them?

   1. Computer vision
   2. Pixel painting
   3. Face finding
   4. Number magic

8. When you use a phone camera and boxes appear around people's faces, what is happening?

   1. The faces are glowing because they are special
   2. The phone is asking you who is in the picture
   3. AI is using computer vision to find faces
   4. The camera is broken and showing errors

9. If you changed a photo so that every blue pixel became a red pixel, would AI still recognize what was in the picture?

   1. No, because the picture would be broken
   2. No, because AI would see only red and think it is something new
   3. Yes, if the overall pattern of numbers still matches what AI learned
   4. Yes, because AI ignores all colors anyway

10. What does AI actually 'see' when it looks at a photo?

    1. A smaller version of the photo
    2. Nothing—it just guesses randomly
    3. A giant grid of numbers representing colors
    4. The actual objects like cats and dogs

11. What is the main way AI differs from human vision?

    1. AI can see better than humans in all situations
    2. AI sees numbers and patterns, while humans see objects directly
    3. AI can see through walls
    4. AI does not need light to see pictures

12. Why do self-driving cars need computer vision?

    1. So they can recognize traffic signs, pedestrians, and other cars
    2. So they can tell if the sky is cloudy
    3. So they can see better than human drivers
    4. So they can drive while the passengers sleep

13. What would happen if you gave AI a completely blank white image?

    1. AI would crash
    2. AI would see a grid of the same number repeated (representing white)
    3. AI would refuse to look at it
    4. AI would see a hidden picture

14. What makes facial recognition on phones work?

    1. The phone measures the actual distance between your eyes
    2. AI converts the face into number patterns and matches them
    3. The face sends a signal to the phone
    4. The phone compares the face to photos in your gallery

15. If you drew a picture with just black and white dots, could AI still recognize what it shows?

    1. Yes, because AI ignores colors completely
    2. Yes, if the pattern of dots matches something AI has learned
    3. No, because AI only understands color photos
    4. No, because AI cannot see drawings
