[Q]: Passage: In November 1944, after Greece was liberated from Germany, old drachmae were exchanged for new ones at the rate of 50,000,000,000 to 1. Only paper money was issued. The government issued notes of 1, 5, 10 and 20 drachmae, with the Bank of Greece issuing 50-, 100-, 500-, 1000-, 5000-, and 10,000-drachma notes. This drachma also suffered from high inflation. The government later issued 100-, 500-, and 1000-drachma notes, and the Bank of Greece issued 20,000-and 50,000-drachma notes. Third modern drachma coins The first issue of coins minted in 1954 consisted of holed aluminium 5-, 10- and 20-lepton pieces, with 50-lepton, 1-, 2-, 5- and 10-drachma pieces in cupro-nickel. A silver 20-drachma piece was issued in 1960, replacing the 20-drachma banknote, and also minted only in collector sets in 1965.  Coins in denominations from 50 lepta to 20 drachmae carried a portrait of Paul of Greece (1947–1964). New coins were introduced in 1966, ranging from 50 lepta to 10 drachmae, depicting Constantine II of Greece (1964–1974). A silver 30 drachma coin for the centennial of Greeces royal dynasty was minted in 1963.  The following year a non-circulating coin of this value was produced to commemorate the royal wedding.  The reverse of all coins was altered in 1971 to reflect the military junta which was in power from 1967 to 1974. This design included a soldier standing in front of the flames of the rising phoenix.

[Q]: Passage: Despite its occurrence at the height of World War I, the roots of the February Revolution date further back. Chief among these was Imperial Russia's failure, throughout the 19th and early 20th century, to modernize its archaic social, economic and political structures while maintaining the stability of ubiquitous devotion to an autocratic monarch. As historian Richard Pipes writes, "the incompatibility of capitalism and autocracy struck all who gave thought to the matter". The first major event of the Russian Revolution was the February Revolution, which was a chaotic affair, caused by the culmination of over a century of civil and military unrest. There were many causes of this unrest of the common people towards the Tsar and aristocratic landowners. The causes can be summarized as the ongoing cruel treatment of peasants by the bourgeoisie, poor working conditions of industrial workers and the spreading of western democratic ideas by political activists. All of these causes led to a growing political and social awareness in the lower classes of Russia. Dissatisfaction of proletarians was compounded by food shortages and military failures. In 1905, Russia experienced humiliating losses in its war with Japan, then Bloody Sunday and the Revolution of 1905, in which Tsarist troops fired upon a peaceful, unarmed crowd, further dividing Nicholas II from his people. Widespread strikes, riots and the famous mutiny on the Battleship Potemkin ensued. These conditions caused much agitation among the small working and professional classes. This tension erupted into general revolt with the 1905 Revolution, and again under the strain of war in 1917, this time with lasting consequences.
Question: Which event happened in 1905?
[A]:
