Article: Chopin's harmonic innovations may have arisen partly from his keyboard improvisation technique. Temperley says that in his works "novel harmonic effects frequently result from the combination of ordinary appoggiaturas or passing notes with melodic figures of accompaniment", and cadences are delayed by the use of chords outside the home key (neapolitan sixths and diminished sevenths), or by sudden shifts to remote keys. Chord progressions sometimes anticipate the shifting tonality of later composers such as Claude Debussy, as does Chopin's use of modal harmony.

Question: Chopin's chord progressions are similar in style to what other composer?
Ans: Claude Debussy

Article: There have been instances where a country's government bans a movie, resulting in the spread of copied videos and DVDs. Romanian-born documentary maker Ilinca Calugareanu wrote a New York Times article telling the story of Irina Margareta Nistor, a narrator for state TV under Nicolae Ceausescu's regime. A visitor from the west gave her bootlegged copies of American movies, which she dubbed for secret viewings through Romania. According to the article, she dubbed more than 3,000 movies and became the country's second-most famous voice after Ceausescu, even though no one knew her name until many years later.

Question: How many movies did Nistor dub for secret viewings in Romania?
Ans: 3,000

Article: Glacial abrasion is commonly characterized by glacial striations. Glaciers produce these when they contain large boulders that carve long scratches in the bedrock. By mapping the direction of the striations, researchers can determine the direction of the glacier's movement. Similar to striations are chatter marks, lines of crescent-shape depressions in the rock underlying a glacier. They are formed by abrasion when boulders in the glacier are repeatedly caught and released as they are dragged along the bedrock.

Question: What cause glacial stiations?
Ans: large boulders that carve long scratches in the bedrock
