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 many people live on Earth? 8.1B — 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 5.7B to 11B is a tenth of the track and scores 90; the whole track scores 0.
- What is the diameter of Jupiter? 86,900 miles — 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 55,000 to 140,000 is a tenth of the track and scores 90; the whole track scores 0.
- How many seconds are in a year? 31.5M — 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 22M to 45M is a tenth of the track and scores 90; the whole track scores 0.
- What year was Coca-Cola invented? 1,886 — near the middle of its track. A bracket from 1,872 to 1,900 is a tenth of the track and scores 90; the whole track scores 0.
- How many inches are in 43 yards? 1,548 — 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 1,100 to 2,100 is a tenth of the track and scores 90; the whole track scores 0.
