Example Input: Question: Who was the youngest coach selected to participate in the Triple-A All-Star Game? Passage:Five former Sounds players later served as coaches for the team.

Example Input: Question: What percent of daylight is scattered in the atmosphere? Passage:The source of all daylight is the Sun. The proportion of direct to diffuse light impacts the amount and quality of daylight. "Direct sunlight" reaches a site without being scattered within Earth's atmosphere. Light that is scattered in the atmosphere is diffused daylight. Ground reflected light also contributes to the daylight. Each climate has different composition of these daylights and different cloud coverage, so daylighting strategies vary with site locations and climates. There is no direct sunlight on the polar-side wall (north-facing wall in the Northern Hemisphere and south-facing wall in the Southern Hemisphere) of a building from the autumnal equinox to the spring equinox at latitudes north of the Tropic of Cancer and south of the Tropic of Capricorn.
