instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
What is reduced by playback equipment?, Context: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.
answer:
treble


question:
Did the Tulsa Talons move to San Antonio first or did the Tulsa Shock move to Dallas-Fort Worth first?, Context: Oklahoma has teams in basketball, football, arena football, baseball, soccer, hockey, and wrestling located in Oklahoma City, Tulsa, Enid, Norman, and Lawton. The Oklahoma City Thunder of the National Basketball Association (NBA) is the state's only major league sports franchise. The state had a team in the Women's National Basketball Association, the Tulsa Shock, from 2010 through 2015, but the team relocated to Dallas–Fort Worth after that season and became the Dallas Wings. Oklahoma supports teams in several minor leagues, including Minor League Baseball at the AAA and AA levels (Oklahoma City Dodgers and Tulsa Drillers, respectively), hockey's ECHL with the Tulsa Oilers, and a number of indoor football leagues. In the last-named sport, the state's most notable team was the Tulsa Talons, which played in the Arena Football League until 2012, when the team was moved to San Antonio. The Oklahoma Defenders replaced the Talons as Tulsa's only professional arena football team, playing the CPIFL. The Oklahoma City Blue, of the NBA Development League, relocated to Oklahoma City from Tulsa in 2014, where they were formerly known as the Tulsa 66ers. Tulsa is the base for the Tulsa Revolution, which plays in the American Indoor Soccer League. Enid and Lawton host professional basketball teams in the USBL and the CBA.
answer:
Tulsa Talons


question:
What is the exposure length of the safe limit of fumes in minutes?, Context: People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that effect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement.
