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.
- How fast do you have to go to escape Earth’s gravity? 25,000 miles per hour — 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 18,000 to 35,000 is a tenth of the track and scores 90; the whole track scores 0.
- How many people live in Australia? 27M — 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 19M to 38M is a tenth of the track and scores 90; the whole track scores 0.
- What year did the French Revolution begin? 1,789 — near the middle of its track. A bracket from 1,769 to 1,809 is a tenth of the track and scores 90; the whole track scores 0.
- How much of the air is oxygen? 21 percent — in the lower third of its track. A bracket from 16 to 26 is a tenth of the track and scores 90; the whole track scores 0.
- How many minutes are in 24 days? 34,560 — in the upper third of its track (a logarithmic track, so a tenth of it is a tenth of the powers of ten it spans). A bracket from 27,000 to 44,000 is a tenth of the track and scores 90; the whole track scores 0.
