Example input: what is the first event mentioned?, Context: The Russian Revolution is the series of revolutions in Russia in 1917, which destroyed the Tsarist autocracy and led to the creation of the Soviet Union. Following the abdication of Nicholas II of Russia, the Russian Provisional Government was established. In October 1917, a red faction revolution occurred in which the Red Guard, armed groups of workers and deserting soldiers directed by the Bolshevik Party, seized control of Saint Petersburg (then known as Petrograd) and began an immediate armed takeover of cities and villages throughout the former Russian Empire.

Q: Which happened first, the United States declared independence or the decisive defeat at Yorktown?, Context: During the 1760s and early 1770s, relations between the Thirteen Colonies and Britain became increasingly strained, primarily because of resentment of the British Parliament's attempts to govern and tax American colonists without their consent. This was summarised at the time by the slogan "No taxation without representation", a perceived violation of the guaranteed Rights of Englishmen. The American Revolution began with rejection of Parliamentary authority and moves towards self-government. In response Britain sent troops to reimpose direct rule, leading to the outbreak of war in 1775. The following year, in 1776, the United States declared independence. The entry of France to the war in 1778 tipped the military balance in the Americans' favour and after a decisive defeat at Yorktown in 1781, Britain began negotiating peace terms. American independence was acknowledged at the Peace of Paris in 1783.
A:
the United States declared independence
