Article: The immediate predecessors of MP3 were "Optimum Coding in the Frequency Domain" (OCF), and Perceptual Transform Coding (PXFM). These two codecs, along with block-switching contributions from Thomson-Brandt, were merged into a codec called ASPEC, which was submitted to MPEG, and which won the quality competition, but that was mistakenly rejected as too complex to implement. The first practical implementation of an audio perceptual coder (OCF) in hardware (Krasner's hardware was too cumbersome and slow for practical use), was an implementation of a psychoacoustic transform coder based on Motorola 56000 DSP chips.

Question: What was the name of the codec that OCF, PFXM and other contributes merged into?
Ans: ASPEC

Article: In the view of many associated with the Radical Reformation, the Magisterial Reformation had not gone far enough. Radical Reformer, Andreas von Bodenstein Karlstadt, for example, referred to the Lutheran theologians at Wittenberg as the "new papists". Since the term "magister" also means "teacher", the Magisterial Reformation is also characterized by an emphasis on the authority of a teacher. This is made evident in the prominence of Luther, Calvin, and Zwingli as leaders of the reform movements in their respective areas of ministry. Because of their authority, they were often criticized by Radical Reformers as being too much like the Roman Popes. A more political side of the Radical Reformation can be seen in the thought and practice of Hans Hut, although typically Anabaptism has been associated with pacifism.

Question: What is another name for magister?
Ans: teacher

Article: The Hortensian Law deprived the patricians of their last weapon against the plebeians, and thus resolved the last great political question of the era. No such important political changes occurred between 287 BC and 133 BC. The important laws of this era were still enacted by the senate. In effect, the plebeians were satisfied with the possession of power, but did not care to use it. The senate was supreme during this era because the era was dominated by questions of foreign and military policy. This was the most militarily active era of the Roman Republic.

Question: What group of people often failed to use the power that was given to them?
Ans:
the plebeians
