[EX Q]: Passage: The preludes, many of which are very brief (some consisting of simple statements and developments of a single theme or figure), were described by Schumann as "the beginnings of studies". Inspired by J.S. Bach's The Well-Tempered Clavier, Chopin's preludes move up the circle of fifths (rather than Bach's chromatic scale sequence) to create a prelude in each major and minor tonality. The preludes were perhaps not intended to be played as a group, and may even have been used by him and later pianists as generic preludes to others of his pieces, or even to music by other composers, as Kenneth Hamilton suggests: he has noted a recording by Ferruccio Busoni of 1922, in which the Prelude Op. 28 No. 7 is followed by the Etude Op. 10 No. 5. Question: What piece of Bach's did Chopin take inspiration for his preludes?
[EX A]: The Well-Tempered Clavier

[EX Q]: Passage: Paragraph 6 of Article 29 stated that if a petition was successful a referendum should be held within three years. Since the deadline passed on 5 May 1958 without anything happening the Hesse state government filed a constitutional complaint with the Federal Constitutional Court in October 1958. The complaint was dismissed in July 1961 on the grounds that Article 29 had made the new delimitation of the federal territory an exclusively federal matter. At the same time, the Court reaffirmed the requirement for a territorial revision as a binding order to the relevant constitutional bodies. Question: When was the Hesse state government's complaint dismissed?
[EX A]: July 1961

[EX Q]: Passage: From 22 March through 26 March 1991, mass pro-democracy rallies and a nationwide strike was held in both urban and rural communities, which became known as les evenements ("the events") or the March Revolution.

Despite an estimated loss of 300 lives over the course of four days, nonviolent protesters continued to return to Bamako each day demanding the resignation of the dictatorial president and the implementation of democratic policies. Question: After the president declared a state of emergency, what type of curfew was placed on the country?

nightly
