Question: World War I was a watershed event in human history, changing views of governments and politics. The Russian Revolution of 1917 (and similar, albeit less successful, revolutions in many other European countries) brought communism - and in particular the political theory of Leninism, but also on a smaller level Luxemburgism (gradually) - on the world stage. At the same time, social democratic parties won elections and formed governments for the first time, often as a result of the introduction of universal suffrage. However, a group of central European economists led by Austrian School economists Ludwig von Mises and Friedrich Hayek identified the collectivist underpinnings to the various new socialist and fascist doctrines of government power as being different brands of political totalitarianism.
Is there an answer to this question: What changed because of Leninism?

Answer: unanswerable

Question: The mosaics of the Church of St Stephen in ancient Kastron Mefaa (now Umm ar-Rasas) were made in 785 (discovered after 1986). The perfectly preserved mosaic floor is the largest one in Jordan. On the central panel hunting and fishing scenes are depicted while another panel illustrates the most important cities of the region. The frame of the mosaic is especially decorative. Six mosaic masters signed the work: Staurachios from Esbus, Euremios, Elias, Constantinus, Germanus and Abdela. It overlays another, damaged, mosaic floor of the earlier (587) "Church of Bishop Sergius." Another four churches were excavated nearby with traces of mosaic decoration.
Is there an answer to this question: How many artists signed the frame of the mosaic at the Church of St Stephen?

Answer: Six

Question: During the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overseas empires. Envious of the great wealth these empires generated, England, France, and the Netherlands began to establish colonies and trade networks of their own in the Americas and Asia. A series of wars in the 17th and 18th centuries with the Netherlands and France left England (and then, following union between England and Scotland in 1707, Great Britain) the dominant colonial power in North America and India.
Is there an answer to this question: When did England become Great Britain?

Answer: 1707
