In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: 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.
[A]: treble


[Q]: How was this shown in teaching?, Context: As the Tokugawa period progressed more value became placed on education, and the education of females beginning at a young age became important to families and society as a whole. Marriage criteria began to weigh intelligence and education as desirable attributes in a wife, right along with physical attractiveness. Though many of the texts written for women during the Tokugawa period only pertained to how a woman could become a successful wife and household manager, there were those that undertook the challenge of learning to read, and also tackled philosophical and literary classics. Nearly all women of the samurai class were literate by the end of the Tokugawa period.
[A]: many of the texts written for women during the Tokugawa period only pertained to how a woman could become a successful wife and household manager


[Q]: What do you do when you travel to work, by any means?, Context: Raleigh is also served by Triangle Transit (known formerly as the Triangle Transit Authority, or TTA). Triangle Transit offers scheduled, fixed-route regional and commuter bus service between Raleigh and the region's other principal cities of Durham, Cary and Chapel Hill, as well as to and from the Raleigh-Durham International Airport, Research Triangle Park and several of the region's larger suburban communities. Triangle Transit also coordinates an extensive vanpool and rideshare program that serves the region's larger employers and commute destinations.
