Five hot air balloons at different distances in an open sky above a grassy field.
  1. Assuming all the balloons in the picture above are the same true physical size, which is closest to the observer?
  2. Again assuming the balloons are the same size, which is farthest away?
  3. Still assuming the balloons are the same size, where are B and E in relation to the observer and each other?
    • E is twice as close to the observer as B.
    • B is about the same distance from the observer as E.
    • B is twice as close to the observer as E.
    • B is four times closer than E.
    • B is eight times closer than E.
  4. Now, let's change this assumption. Suppose C is twice as big as D. If C is 2 miles away, how far is D?
    • 1 mile
    • 2 miles
    • 4 miles
    • 3.659 miles
    • It is impossible to say.
