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.
- What is absolute zero, in degrees Fahrenheit? -460 degrees Fahrenheit — near the middle of its track. A bracket from -510 to -410 is a tenth of the track and scores 90; the whole track scores 0.
- How tall is the statue of Christ the Redeemer in Rio, without its pedestal? 98 feet — in the lower third of its track. A bracket from 75 to 120 is a tenth of the track and scores 90; the whole track scores 0.
- At 72 beats a minute, how many times does a heart beat in 3 hours? 12,960 — 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 9,200 to 18,000 is a tenth of the track and scores 90; the whole track scores 0.
- How many primes are there under 100? 25 — in the lower third of its track. A bracket from 20.5 to 29.5 is a tenth of the track and scores 90; the whole track scores 0.
- How high is a basketball hoop? 10 feet — near the middle of its track. A bracket from 9.3 to 10.8 is a tenth of the track and scores 90; the whole track scores 0.
