Problem: Electric motor:

A major turning point in the development of DC machines took place in 1864, when Antonio Pacinotti described for the first time the ring armature with its symmetrically grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the invention by Zénobe Gramme who, in 1871, reinvented Pacinotti's design. In 1873, Gramme showed that his dynamo could be used as a motor, which he demonstrated to great effect at exhibitions in Vienna and Philadelphia by connecting two such DC motors at a distance of up to 2 km away from each other, one as a generator. (See also 1873 : l'expérience décisive [Decisive Workaround] .)

 In what two cities did Gramme never conduct his demonstrations?

A: unanswerable


Problem: The emperor Julian made a short-lived attempt to revive traditional and Hellenistic religion and to affirm the special status of Judaism, but in 380 under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Pleas for religious tolerance from traditionalists such as the senator Symmachus (d. 402) were rejected. Christianity became increasingly popular. Heretics as well as non-Christians were subject to exclusion from public life or persecution, but Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms, and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
What aspects of Roman religion influenced Christian forms?

Answer: ritual


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Royal assent is not sufficient to give legal effect to an Act of Tynwald. By ancient custom, an act did not come into force until it had been promulgated at an open-air sitting of Tynwald, usually held on Tynwald Hill at St John's on St John's Day (24 June), but, since the adoption of the Gregorian calendar in 1753, on 5 July (or on the following Monday if 5 July is a Saturday or Sunday). Promulgation originally consisted of the reading of the Act in English and Manx; but, after 1865 the reading of the title of the act and a summary of each section were sufficient. This was reduced in 1895 to the titles and a memorandum of the object and purport of the act, and, since 1988, only the short title and a summary of the long title have been read.
How much of the proposed act must be currently read aloud on St John's Day?
A: only the short title and a summary of the long title


Context and question: From the American Civil War until the mid-20th century, Philadelphia was a bastion of the Republican Party, which arose from the staunch pro-Northern views of Philadelphia residents during and after the war (Philadelphia was chosen as the host city for the first Republican National Convention in 1856). After the Great Depression, Democratic registrations increased, but the city was not carried by Democrat Franklin D. Roosevelt in his landslide victory of 1932 (in which Pennsylvania was one of the few states won by Republican Herbert Hoover). Four years later, however, voter turnout surged and the city finally flipped to the Democrats. Roosevelt carried Philadelphia with over 60% of the vote in 1936. The city has remained loyally Democratic in every presidential election since. It is now one of the most Democratic in the country; in 2008, Democrat Barack Obama drew 83% of the city's vote. Obama's win was even greater in 2012, capturing 85% of the vote.
What happened in Philadelphia in 1856?
Answer: Philadelphia was chosen as the host city for the first Republican National Convention in 1856


Question: A second neoclassic wave, more severe, more studied and more consciously archaeological, is associated with the height of the Napoleonic Empire. In France, the first phase of neoclassicism was expressed in the "Louis XVI style", and the second in the styles called "Directoire" or Empire. The Rococo style remained popular in Italy until the Napoleonic regimes brought the new archaeological classicism, which was embraced as a political statement by young, progressive, urban Italians with republican leanings.[according to whom?]
Is there an answer to this question: Who oppose the archaeological classism brought by the Napoleonic regimes?

Answer: unanswerable


Question: In 1982, Regis McKenna was brought in to shape the marketing and launch of the Macintosh. Later the Regis McKenna team grew to include Jane Anderson, Katie Cadigan and Andy Cunningham, who eventually led the Apple account for the agency. Cunningham and Anderson were the primary authors of the Macintosh launch plan. The launch of the Macintosh pioneered many different tactics that are used today in launching technology products, including the "multiple exclusive," event marketing (credited to John Sculley, who brought the concept over from Pepsi), creating a mystique around a product and giving an inside look into a product's creation.
Is there an answer to this question: Who was brought in to shape the marketing of Macintosh in 1928?

Answer:
unanswerable
