  1. A frog uses touch to detect movement on its sticky tongue. What happens next in the information model?

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

  2. Which response fits the deer's sensed information: crackling leaves behind it?

    • the deer freezes and runs away
    • the dog walks toward the hidden toy
    • the rabbit runs into its burrow
    • the frog closes its mouth around the insect

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

    • sight
    • smell
    • hearing
    • touch

  4. Which model order shows how the dog responds?

    • response -> no information -> no processing
    • detects a scent trail across the grass -> the brain uses the smell to follow the trail -> the dog walks toward the hidden toy
    • fossil -> erosion -> the dog walks toward the hidden toy
    • the dog walks toward the hidden toy -> the brain uses the smell to follow the trail -> detects a scent trail across the grass

  5. Why is "the rabbit grows longer ears that instant" not a good response model for the rabbit?

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

  6. 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 visual information to aim
    • the brain uses the smell to follow the trail
    • the brain compares the sound with danger signals

  7. Which response fits the owl's sensed information: a mouse moving in dim light?

    • the dog walks toward the hidden toy
    • the owl swoops toward the mouse
    • the rabbit runs into its burrow
    • the owl grows thicker feathers at once

  8. Which sense gives the rabbit this information: a loud clap near the garden?

    • sight
    • hearing
    • touch
    • smell

  9. Which model order shows how the rabbit responds?

    • detects a loud clap near the garden -> the brain quickly connects the sound with possible danger -> the rabbit runs into its burrow
    • the rabbit runs into its burrow -> the brain quickly connects the sound with possible danger -> detects a loud clap near the garden
    • response -> no information -> no processing
    • fossil -> erosion -> the rabbit runs into its burrow

  10. Why is "the deer grows new antlers immediately" not a good response model for the deer?

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