Input: Read this: It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.
Question: What allowed better sounds inside the cabinet of the orthoponic phonograph?

Output: folded horn with an exponential taper


Input: Read this: The Age of Enlightenment was preceded by and closely associated with the scientific revolution. Earlier philosophers whose work influenced the Enlightenment included Francis Bacon, Descartes, Locke, and Spinoza. The major figures of the Enlightenment included Cesare Beccaria, Voltaire, Denis Diderot, Jean-Jacques Rousseau, David Hume, Adam Smith, and Immanuel Kant. Some European rulers, including Catherine II of Russia, Joseph II of Austria and Frederick I of Prussia, tried to apply Enlightenment thought on religious and political tolerance, which became known as enlightened absolutism. The Americans Benjamin Franklin and Thomas Jefferson came to Europe during the period and contributed actively to the scientific and political debate, and the ideals of the Enlightenment were incorporated into the United States Declaration of Independence and the Constitution of the United States.
Question: Trying to apply Enlightenment thought on religious and political tolerance became known as what?

Output: enlightened absolutism


Input: Read this: What is today the Central African Republic has been inhabited for millennia; however, the country's current borders were established by France, which ruled the country as a colony starting in the late 19th century. After gaining independence from France in 1960, the Central African Republic was ruled by a series of autocratic leaders; by the 1990s, calls for democracy led to the first multi-party democratic elections in 1993. Ange-Félix Patassé became president, but was later removed by General François Bozizé in the 2003 coup. The Central African Republic Bush War began in 2004 and, despite a peace treaty in 2007 and another in 2011, fighting broke out between various factions in December 2012, leading to ethnic and religious cleansing of the Muslim minority and massive population displacement in 2013 and 2014.
Question: In what year did the Ange-Felix Patasse war begin?

Output: unanswerable


Input: Read this: Another milestone in the early development of Baptist doctrine was in 1638 with John Spilsbury, a Calvinistic minister who helped to promote the strict practice of believer's baptism by immersion. According to Tom Nettles, professor of historical theology at Southern Baptist Theological Seminary, "Spilsbury's cogent arguments for a gathered, disciplined congregation of believers baptized by immersion as constituting the New Testament church gave expression to and built on insights that had emerged within separatism, advanced in the life of John Smyth and the suffering congregation of Thomas Helwys, and matured in Particular Baptists."
Question: What was Tom Nettles a student of?

Output:
unanswerable
