QUES: In theory at least, all Polish noblemen were social equals. Also in theory, they were legal peers. Those who held 'real power' dignities were more privileged but these dignities were not hereditary. Those who held honorary dignities were higher in 'ritual' hierarchy but these dignities were also granted for a lifetime. Some tenancies became hereditary and went with both privilege and titles. Nobles who were not direct barons of the Crown but held land from other lords were only peers "de iure".

Was was unique about the dignities?
What is the answer?
ANS: not hereditary
QUES: The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).

What is the most common method of organization?
What is the answer?
ANS: twelve-note chromatic scale
QUES: Professor Aram Sinnreich, in his book The Piracy Crusade, states that the connection between declining music sails and the creation of peer to peer file sharing sites such as Napster is tenuous, based on correlation rather than causation. He argues that the industry at the time was undergoing artificial expansion, what he describes as a "'perfect bubble'—a confluence of economic, political, and technological forces that drove the aggregate value of music sales to unprecedented heights at the end of the twentieth century".

What doesn't he call the merging of economic, political and technological forces that drove the music industry?
What is the answer?
ANS:
unanswerable
