[Q]: Passage: The Cowboys' tenth game was an NFC duel with the Lions. In the first quarter the Cowboys pulled ahead with QB Jon Kitna making a 1-yard TD pass to WR Dez Bryant. The Lions replied with kicker Dave Rayner nailing a 47-yard field goal. The Cowboys trailed with QB Shaun Hill making a 9-yard TD pass to WR Nate Burleson, followed by a Penalty on Leonard Davis which was enforced to the endzone for a safety. The Cowboys got the lead back with DB Bryan McCann returning a punt 97 yards for a touchdown, which was followed by Kitna making a 3-yard TD pass to WR Miles Austin. The lead was narrowed with Hill completing a 14-yard TD pass to WR Calvin Johnson. The Cowboys increased their lead with Kitna finding Austin again on a 4-yard TD pass, followed by Kitna's 29-yard scramble to the endzone for a touchdown, which was his longest run of his career. Cowboys interim coach Jason Garrett won his home debut and improved to 2-0 since taking over for Wade Phillips. It's the first time this season Dallas (3-7) has won consecutive games and the first time all season it won at home, having lost the first four.The Lions (2-8) lost their 26th straight on the road, extending a woeful NFL record that began in 2007, when Kitna was their quarterback.Detroit led 12-7 and was consistently stuffing the Cowboys' offense midway through the third quarter when John Wedling jumped over the goal line and tapped a punt back into the field of play.It hopped up waist-high and right to McCann, and the speedster turned it into the second-longest punt return in franchise history - a week after a 101-yard interception return that was the longest in club history. With the win the Cowboys improved to 3-7 on the season.
Question: Who was fired as the Cowboys head coach?

[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?
