Question by question

A question scores 100 minus the bracket’s width as a percentage of the track, if the answer is inside it, and nothing if it is outside. The tenth-of-the-track bracket below is the one a confident player was aiming for.

  1. How tall is the Washington Monument? 555 feet — in the lower third of its track. A bracket from 460 to 660 is a tenth of the track and scores 90; the whole track scores 0.
  2. How many faces does an icosahedron have? 20 — in the lower third of its track. A bracket from 15 to 25 is a tenth of the track and scores 90; the whole track scores 0.
  3. How many breaths does a person take in a day, roughly? 20,000 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 14,000 to 28,000 is a tenth of the track and scores 90; the whole track scores 0.
  4. What is 29 × 77? 2,233 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 1,700 to 2,900 is a tenth of the track and scores 90; the whole track scores 0.
  5. What is 2 to the power of 10? 1,024 — near the middle of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 810 to 1,300 is a tenth of the track and scores 90; the whole track scores 0.
