I think I messed this part up; random.org was down when I took it so I skipped that question and the next, then answered my best guess for redwood height, then realized that I could just make a random number by other means (python), and used that instead. I realized afterwards that it was probably about anchoring, but there was no obvious way to undo that section. Oh well; I was off by more than a factor of 2 regardless, despite having visited redwood national park.
