Question: Who led political movement to get the UK out of the EU? Passage 1:The EU and European citizenship were established when the Maastricht Treaty came into force in 1993. The EU traces its origins to the European Coal and Steel Community (ECSC) and the European Economic Community (EEC), established, respectively, by the 1951 Treaty of Paris and 1957 Treaty of Rome. The original members of what came to be known as the European Communities were the Inner Six: Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany. The Communities and their successors have grown in size by the accession of new member states and in power by the addition of policy areas to their remit. The latest major amendment to the constitutional basis of the EU, the Treaty of Lisbon, came into force in 2009. No member state has left the EU or its antecedent organisations (Greenland, an autonomous territory within Denmark, left the Communities in 1985). The United Kingdom signified its intention to leave after a membership referendum in June 2016 and is negotiating its withdrawal. The United Kingdom and its independent territories are scheduled to leave the European Union by 31 January 2020. 
 Passage 2:In 2019, Lin was optioned to Triple-A Pawtucket prior to Opening Day. He was called up on April 6, when Brock Holt went on the injured list, and optioned back to Pawtucket on April 9, when Dustin Pedroia was activated. Lin was recalled to Boston on April 19 along with Michael Chavis, as both Pedroia and Eduardo Núñez were placed on the injured list. With the 2019 Red Sox only carrying two catchers, manager Alex Cora stated that Lin would be the team's emergency catcher. On May 1, against Oakland Athletics, Lin recorded his 35th MLB hit, passing Chin-lung Hu for most MLB career hits by a Taiwanese player; the majority of Taiwanese players in MLB have been pitchers. On May 3, Lin was removed from a game against the Chicago White Sox after spraining his left knee while sliding into second base; he was placed on the injured list the next day. On June 17, his rehabilitation assignment with Pawtucket was halted due to a right shoulder impingement. He resumed his rehabilitation assignment on June 26, then was activated and optioned to Pawtucket on July 1. Overall during 2019, Lin appeared in 13 games with Boston, batting .200 with one RBI, while with Pawtucket he batted .246 with four home runs and 22 RBIs in 59 games.
 Passage 3:The 1995–96 NBA season was the 76ers 47th season in the National Basketball Association, and 33rd season in Philadelphia. During the offseason, the Sixers signed free agent Vernon Maxwell, then later on signed second-year guard Trevor Ruffin in December. Top draft pick Jerry Stackhouse and Clarence Weatherspoon both provided a nice young nucleus from which to build. However, finding talent to surround them was often difficult, as the Sixers suffered an 11-game losing streak after a 2–2 start. Early into the season, Shawn Bradley was traded to the New Jersey Nets for Derrick Coleman, who only played in just eleven games due to an irregular heartbeat. At midseason, second-year forward Sharone Wright was dealt to the expansion Toronto Raptors as Jeff Malone was released to free agency. The Sixers had their worst season since the infamous 73-loss 1972–73 season, finishing last place in the Atlantic Division with an 18–64 record.
