Question: Who was the head monk at Alvastra Abbey when Stephen lived there? Passage 1:Shortly after he returned to England in bad health. From 1777 to 1779 he commanded , as flag captain to his father at Newfoundland. On his return he was appointed to the 32-gun frigate HMS Pearl, which when cruising near the Azores on 14 September 1779, captured the Spanish frigate Santa Monica of equal force. In December Pearl sailed with the fleet under Sir George Rodney, and assisted in the capture of the Caracas convoy; but having sprung her foremast, was ordered home with the prizes. She was afterwards sent out to North America, and on 30 September 1780, while on a cruise off the Bermudas, captured the Esperance, a frigate-built privateer of 32 guns. In the battle of Cape Henry, on 16 March 1781, she acted as repeating frigate. She was not with the fleet during the battle of the Chesapeake on 5 September, but joined it, still off Cape Henry, on the 14th, and was left to keep watch on the movements of the French till the 25th, when she sailed for New York. On 19 October she sailed again with the fleet, and on the 23rd was stationed ahead as a look-out (Pearl's Log). She returned to England in 1782.
Passage 2:The first Archbishop of Uppsala was Stephen, a Cistercian monk from the celebrated Alvastra Abbey. Cardinal William of Sabina came as papal legate to Sweden during the archiepiscopate of Jarler, a Dominican friar (123555). The legate had been commissioned, among other things, to establish cathedral chapters wherever such were lacking, and to grant them the exclusive right of electing the bishops. Another important matter which the legate had been ordered to carry out was the enforcement of the law of clerical celibacy. At a provincial synod held at Skanninge in 1248 under the presidency of the cardinal, the rules as to celibacy were made more severe. The pious and energetic Archbishop Jarler and his successor Laurentius (125767), a Franciscan, constantly strove to elevate the clergy and to enforce the law of celibacy. A century later Saint Bridget (d. 1373), laboured zealously for the enforcement of the same law.
Passage 3:Held against the backdrop of the 2008 Serbian presidential elections contested between incumbent Boris Tadic from the ruling center-left Democratic Party (DS) and challenger Tomislav Nikolic from the opposition right-wing Serbian Radical Party (SRS) as well as speculation that Albanians from Serbia's province of Kosovo were in the final stages of coordination with the United States to unilaterally declare independence, the festival received plenty of attention both in the Serbian and foreign press. Political angles and overtones dominated foreign press reports such as the one by in center-left Liberation who, after giving praise to the festival for celebrating auteur cinema, wondered if the fact that festival's jury is headed by Peter Handke whom she described as someone "who still smelled of sulfur after being at Milosevic's funeral and who wrote about Serbs in panegyric form due to seeing them unjustly accused of all evils" also mean that Kusturica adheres to these ideas. She answers her own question by saying that, like Handke, Kusturica also believes western Europeans have demonized Serbs and Serbia, but that the Serbian director supports center-left candidate Tadic at the presidential elections.

Question: Which of the Green family's good friends died first? Passage 1:Thomas was born to Thomas Marston Green Sr., a future Colonel in the Continental Army, and Martha Wills. He was born in Williamsburg, Virginia, on February 26, 1758. In 1782 he moved with his family to Natchez District, Mississippi Territory. He would later move to Fayette, Mississippi where he would build the Springfield Plantation, and where he would live until his death. The Green family were good friends with Andrew Jackson and Rachel Donelson. Thomas's brother Abraham married Elizabeth Caffery who was the niece of Rachel Jackson. In August 1791, Andrew Jackson and Rachel were married at the Green Family Springfield Plantation. The marriage ceremony was performed by Thomas Green Sr., while Thomas Jr. served as a witness. Andrew and Rachel would later find out that Rachel's divorce was not finalized, at the time of the wedding.
Passage 2:New York played a pivotal role during the American Revolution and subsequent war. The Stamp Act Congress in 1765 brought together representatives from across the Thirteen Colonies to form a unified response to British policies. The Sons of Liberty were active in New York City to challenge British authority. After a major loss at the Battle of Long Island, the Continental Army suffered a series of additional defeats that forced a retreat from the New York City area, leaving the strategic port and harbor to the British army and navy as their North American base of operations for the rest of the war. The Battle of Saratoga was the turning point of the war in favor of the Americans, convincing France to formally ally with them. New York's constitution was adopted in 1777, and strongly influenced the United States Constitution. New York City was the national capital at various times between 1785 and 1790, where the Bill of Rights was drafted. Albany became the permanent state capital in 1797. In 1787, New York became the eleventh state to ratify the United States Constitution.

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 Nunez 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 199596 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 22 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 197273 season, finishing last place in the Atlantic Division with an 1864 record.
