Task: Question Generation
Input (English): In the sport of athletics, a four-minute mile means completing a mile run (1,760 yards, or 1,609.344 metres) in less than four minutes. It was first achieved in 1954 by Roger Bannister in 3:59.4. The ``four-minute barrier'' has since been broken by over 1,400 male athletes, and is now the standard of all male professional middle distance runners. In the last 50 years the mile record has been lowered by almost 17 seconds, and currently stands at 3:43.13. Running a mile in four minutes translates to a speed of 15 miles per hour (24.14 km/h, or 2:29.13 per kilometre, or 14.91 seconds per 100 metres). It also equals 22 feet per second (1,320 feet per minute).
Output (English): has anyone ever ran a 4 minute mile?
