question:
Passage: On 7 March 1945, the provisional government of the Democratic Federal Yugoslavia (Demokratska Federativna Jugoslavija, DFY) was assembled in Belgrade by Josip Broz Tito, while the provisional name allowed for either a republic or monarchy. This government was headed by Tito as provisional Yugoslav Prime Minister and included representatives from the royalist government-in-exile, among others Ivan Šubašić. In accordance with the agreement between resistance leaders and the government-in-exile, post-war elections were held to determine the form of government. In November 1945, Tito's pro-republican People's Front, led by the Communist Party of Yugoslavia, won the elections with an overwhelming majority, the vote having been boycotted by monarchists. During the period, Tito evidently enjoyed massive popular support due to being generally viewed by the populace as the liberator of Yugoslavia. The Yugoslav administration in the immediate post-war period managed to unite a country that had been severely affected by ultra-nationalist upheavals and war devastation, while successfully suppressing the nationalist sentiments of the various nations in favor of tolerance, and the common Yugoslav goal. After the overwhelming electoral victory, Tito was confirmed as the Prime Minister and the Minister of Foreign Affairs of the DFY. The country was soon renamed the Federal People's Republic of Yugoslavia (FPRY) (later finally renamed into Socialist Federal Republic of Yugoslavia, SFRY). On 29 November 1945, King Peter II was formally deposed by the Yugoslav Constituent Assembly. The Assembly drafted a new republican constitution soon afterwards. Question: Where was the provisional government of the Democratic Federal Yugoslavia assembled?
answer:
Belgrade


question:
Passage: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc², derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincaré (1900), Friedrich Hasenöhrl (1904) and others (see Mass-energy equivalence#History for further information). Question: In what year did Einstein create E = mc2?
answer:
1905


question:
Passage: Where old disc recordings are considered to be of artistic or historic interest, from before the era of tape or where no tape master exists, archivists play back the disc on suitable equipment and record the result, typically onto a digital format, which can be copied and manipulated to remove analog flaws without any further damage to the source recording. For example, Nimbus Records uses a specially built horn record player to transfer 78s. Anyone can do this using a standard record player with a suitable pickup, a phono-preamp (pre-amplifier) and a typical personal computer. However, for accurate transfer, professional archivists carefully choose the correct stylus shape and diameter, tracking weight, equalisation curve and other playback parameters and use high-quality analogue-to-digital converters. Question: Is an original destroyed when transferred to digital format?
answer:

without any further damage to the source recording
