Take the following as truth: Snorkel-fishing with spear-guns is legal, but the fish, which can often be frisky with unarmed snorkellers, now know to scatter at the sight of a harpoon.
Then the following statement: "Since snorkel-fishing with spear guns is legal, the frisky fish have adapted to scattering when they spot a harpoon." is true, false, or inconclusive?
Answer: True
