  1. A dog uses smell to detect a scent trail across the grass. What happens next in the information model?

    • the information skips the brain
    • the brain uses the smell to follow the trail
    • the brain uses the visual information to aim
    • the brain treats the shadow as possible danger

  2. Which response fits the fish's sensed information: a shadow passing over the water?

    • the rabbit runs into its burrow
    • the frog closes its mouth around the insect
    • the deer freezes and runs away
    • the fish darts under a rock

  3. Which sense gives the dog this information: a scent trail across the grass?

    • smell
    • sight
    • hearing
    • touch

  4. Which model order shows how the deer responds?

    • the deer freezes and runs away -> the brain compares the sound with danger signals -> detects crackling leaves behind it
    • detects crackling leaves behind it -> the brain compares the sound with danger signals -> the deer freezes and runs away
    • response -> no information -> no processing
    • fossil -> erosion -> the deer freezes and runs away

  5. Why is "the frog changes into a tadpole" not a good response model for the frog?

    • it does not follow from the sensed information
    • it is the only possible behavior
    • it is the exact response shown by the evidence
    • it explains how the brain processes the signal

  6. A owl uses sight to detect a mouse moving in dim light. What happens next in the information model?

    • the brain uses the visual information to aim
    • the brain signals the mouth to close
    • the brain treats the shadow as possible danger
    • the brain uses the smell to follow the trail

  7. Which response fits the frog's sensed information: movement on its sticky tongue?

    • the rabbit runs into its burrow
    • the frog closes its mouth around the insect
    • the fish darts under a rock
    • the owl swoops toward the mouse

  8. Which sense gives the owl this information: a mouse moving in dim light?

    • touch
    • hearing
    • sight
    • smell

  9. Which model order shows how the frog responds?

    • response -> no information -> no processing
    • detects movement on its sticky tongue -> the brain signals the mouth to close -> the frog closes its mouth around the insect
    • fossil -> erosion -> the frog closes its mouth around the insect
    • the frog closes its mouth around the insect -> the brain signals the mouth to close -> detects movement on its sticky tongue

  10. Why is "the dog changes its fur color" not a good response model for the dog?

    • it is the only possible behavior
    • it is the exact response shown by the evidence
    • it does not follow from the sensed information
    • it explains how the brain processes the signal
