Problem: Strasbourg:

Following the defeat of the German empire in World War I and the abdication of the German Emperor, some revolutionary insurgents declared Alsace-Lorraine as an independent Republic, without preliminary referendum or vote. On 11 November 1918 (Armistice Day), communist insurgents proclaimed a "soviet government" in Strasbourg, following the example of Kurt Eisner in Munich as well as other German towns. French troops commanded by French general Henri Gouraud entered triumphantly in the city on 22 November. A major street of the city now bears the name of that date (Rue du 22 Novembre) which celebrates the entry of the French in the city. Viewing the massive cheering crowd gathered under the balcony of Strasbourg's town hall, French President Raymond Poincare stated that "the plebiscite is done".

Who was made ruler of Strasburg when it was proclaimed as a "soviet government"?

A: unanswerable

Problem: Boston:

Many of the crucial events of the American Revolutionthe Boston Massacre, the Boston Tea Party, Paul Revere's midnight ride, the battles of Lexington and Concord and Bunker Hill, the Siege of Boston, and many othersoccurred in or near Boston. After the Revolution, Boston's long seafaring tradition helped make it one of the world's wealthiest international ports, with rum, fish, salt, and tobacco being particularly important.

Boston became one of the wealthiest international ports after what war?
---
A: the American Revolution

Problem: Red:

Surveys show that red is the color most associated with courage. In western countries red is a symbol of martyrs and sacrifice, particularly because of its association with blood. Beginning in the Middle Ages, the Pope and Cardinals of the Roman Catholic Church wore red to symbolize the blood of Christ and the Christian martyrs. The banner of the Christian soldiers in the First Crusade was a red cross on a white field, the St. George's Cross. According to Christian tradition, Saint George was a Roman soldier who was a member of the guards of the Emperor Diocletian, who refused to renounce his Christian faith and was martyred. The Saint George's Cross became the Flag of England in the 16th century, and now is part of the Union Flag of the United Kingdom, as well as the Flag of the Republic of Georgia.

Why did the Popes of the middle ages wear red?
---
A: to symbolize the blood of Christ and the Christian martyrs

Problem: MP3:

The psychoacoustic masking codec was first proposed in 1979, apparently independently, by Manfred R. Schroeder, et al. from Bell Telephone Laboratories, Inc. in Murray Hill, NJ, and M. A. Krasner both in the United States. Krasner was the first to publish and to produce hardware for speech (not usable as music bit compression), but the publication of his results as a relatively obscure Lincoln Laboratory Technical Report did not immediately influence the mainstream of psychoacoustic codec development. Manfred Schroeder was already a well-known and revered figure in the worldwide community of acoustical and electrical engineers, but his paper was not much noticed, since it described negative results due to the particular nature of speech and the linear predictive coding (LPC) gain present in speech. Both Krasner and Schroeder built upon the work performed by Eberhard F. Zwicker in the areas of tuning and masking of critical bands, that in turn built on the fundamental research in the area from Bell Labs of Harvey Fletcher and his collaborators. A wide variety of (mostly perceptual) audio compression algorithms were reported in IEEE's refereed Journal on Selected Areas in Communications. That journal reported in February 1988 on a wide range of established, working audio bit compression technologies, some of them using auditory masking as part of their fundamental design, and several showing real-time hardware implementations.

What does LPC stand for?

A:
linear predictive coding
