[Q]: Passage: The Confederation-controlled Ava was next. Bayinnaung made extensive preparations, assembling a large invasion force . In December 1554, the Toungoo land and naval forces invaded. Within a month, the invasion forces held complete command of the river and the country. On 22 January 1555, the southern forces took the city. Bayinnaung then planned to follow up to the Confederation's home states to prevent future Shan raids into Upper Burma. With the entire Irrawaddy valley under his control, he was able to raise a large army of 24,000 men, 1200 horses and 60 elephants, and invaded the Shan states in January 1557. The massive show of force worked. Shan states one after another submitted with minimal resistance. By March 1557, Bayinnaung in one stroke controlled all cis-Salween  Shan states from the Patkai range at the Assamese border in the northwest to Mohnyin , Mogaung  in present-day Kachin State to Momeik  Thibaw , and Mone  in the east.
Question: How many months did it take for Bayinnaung to take over Ava?

[Q]: Passage: Since the end of World War II, in part due to industrial size and the onset of the Cold War, the United States has often been a proponent of reduced tariff-barriers and free trade. The U.S. helped establish the General Agreement on Tariffs and Trade  and later the World Trade Organization ; although it had rejected an earlier version in the 1950s . Since the 1970s, U.S. governments have negotiated managed-trade agreements, such as the North American Free Trade Agreement  in the 1990s, the Dominican Republic-Central America Free Trade Agreement  in 2006, and a number of bilateral agreements . In Europe, six countries formed the European Coal and Steel Community  in 1951 which became the European Economic Community  in 1958. Two core objectives of the EEC were the development of a common market, subsequently renamed the single market, and establishing a customs union between its member states. After expanding its membership, the EEC became the European Union  in 1993. The European Union, now the world's largest single market, has concluded free trade agreements with many countries around the world.
Question: When did the countries that later formed the European Union first join?
[A]: date


[Q]: Passage: From 2002–11, there has been negative net migration, with an annual negative 109 net immigrants from 2006–11. In 2009 there were 1,820 arrivals and 1,736 departures, for a positive rate of 84 immigrants. This was the first time since collecting data in 2002, there was a positive rate. Data on arrivals and departures collected by the Nauruan Customs and Immigration Office is not available, so specific immigration data is unavailable. As of the 2011 census, 57% of the population over 15 years old were legally or de facto married, 35% were never married, while 7% were either widowed, separated, or divorced. There are 1,647 households in Nauru, making an average household size of 6.0 persons per household.
