Question: How many years has the U.S. supported the World Trade Organization? Passage:However, Berman concurs with many on the right on a number of issues, particularly foreign policy and trade. Berman voted in support of the invasion of Iraq in both 1991 and 2003, as well as for the FISA Amendments Act of 2008, positions that have hurt his standing among many liberals in his district. While he generally supports free trade - for instance, voting in favor of the North American Free Trade Agreement (NAFTA) and various trade agreements with specific countries -, he voted against the more recent Central America Free Trade Agreement (CAFTA). He opposes withdrawing U.S. support for the World Trade Organization. In that same year, he also voted to phase out many farm subsidy programs put into place by the administration of President Franklin Delano Roosevelt as part of the "New Deal."

Question: What team did the captain that left Stoke in 2007 go to? Passage:He joined fellow Championship side Stoke City for a 225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.
