  1. A deer uses hearing to detect crackling leaves behind it. What happens next in the information model?

    • the brain uses the visual information to aim
    • the information skips the brain
    • the brain compares the sound with danger signals
    • the brain signals the mouth to close

  2. Which response fits the rabbit's sensed information: a loud clap near the garden?

    • the frog closes its mouth around the insect
    • the dog walks toward the hidden toy
    • the fish darts under a rock
    • the rabbit runs into its burrow

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

    • hearing
    • sight
    • touch
    • smell

  4. Which model order shows how the fish responds?

    • detects a shadow passing over the water -> the brain treats the shadow as possible danger -> the fish darts under a rock
    • response -> no information -> no processing
    • the fish darts under a rock -> the brain treats the shadow as possible danger -> detects a shadow passing over the water
    • fossil -> erosion -> the fish darts under a rock

  5. Why is "the owl grows thicker feathers at once" not a good response model for the owl?

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

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

    • the brain quickly connects the sound with possible danger
    • the information skips the brain
    • the brain compares the sound with danger signals
    • the brain uses the smell to follow the trail

  7. Which response fits the dog's sensed information: a scent trail across the grass?

    • the owl swoops toward the mouse
    • the dog changes its fur color
    • the rabbit runs into its burrow
    • the dog walks toward the hidden toy

  8. Which sense gives the deer this information: crackling leaves behind it?

    • smell
    • touch
    • hearing
    • sight

  9. Which model order shows how the rabbit responds?

    • fossil -> erosion -> the rabbit runs into its burrow
    • response -> no information -> no processing
    • 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

  10. Why is "the fish makes a fossil" not a good response model for the fish?

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