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]: What was important to preachers?, Context: Doctrinal development has had an important place in the restoration of the Preachers. Several institutions, besides those already mentioned, played important parts. Such is the Biblical school at Jerusalem, open to the religious of the order and to secular clerics, which publishes the Revue Biblique. The faculty of theology at the University of Fribourg, confided to the care of the Dominicans in 1890, is flourishing, and has about 250 students. The Pontificium Collegium Internationale Angelicum, the future Pontifical University of Saint Thomas Aquinas, Angelicum established at Rome in 1908 by Master Hyacinth Cormier, opened its doors to regulars and seculars for the study of the sacred sciences. In addition to the reviews above are the Revue Thomiste, founded by Père Thomas Coconnier (d. 1908), and the Analecta Ordinis Prædicatorum (1893). Among numerous writers of the order in this period are: Cardinals Thomas Zigliara (d. 1893) and Zephirin González (d. 1894), two esteemed philosophers; Alberto Guillelmotti (d. 1893), historian of the Pontifical Navy, and Heinrich Denifle, one of the most famous writers on medieval history (d. 1905).[citation needed]
[A]: the restoration of the Preachers


[Q]: What system of belief operated outside of organized religion while still acknowledging a source of creation?, Context: A number of novel ideas about religion developed with the Enlightenment, including Deism and talk of atheism. Deism, according to Thomas Paine, is the simple belief in God the Creator, with no reference to the Bible or any other miraculous source. Instead, the Deist relies solely on personal reason to guide his creed, which was eminently agreeable to many thinkers of the time. Atheism was much discussed, but there were few proponents. Wilson and Reill note that, "In fact, very few enlightened intellectuals, even when they were vocal critics of Christianity, were true atheists. Rather, they were critics of orthodox belief, wedded rather to skepticism, deism, vitalism, or perhaps pantheism." Some followed Pierre Bayle and argued that atheists could indeed be moral men. Many others like Voltaire held that without belief in a God who punishes evil, the moral order of society was undermined. That is, since atheists gave themselves to no Supreme Authority and no law, and had no fear of eternal consequences, they were far more likely to disrupt society. Bayle (1647–1706) observed that in his day, "prudent persons will always maintain an appearance of [religion].". He believed that even atheists could hold concepts of honor and go beyond their own self-interest to create and interact in society. Locke said that if there were no God and no divine law, the result would be moral anarchy: every individual "could have no law but his own will, no end but himself. He would be a god to himself, and the satisfaction of his own will the sole measure and end of all his actions".
[A]:
Deism
