  1. This last choice is correct. Fantastic reasoning if you figured that one out. As
  2. an example, the first number could be 4 and the second one could be 0. We know 4
  3. times 0 equals 0. And let's say the second number is 5. 0 times 5 equals 0. Now,
  4. I don't actually know that one of the numbers is 4 or the other is 5, but one of
  5. them must equal 0, since our product is 0.
