Question: Who is the current president of the university that Boston College lost to in the opening round of the 65th Annual Beanpot Tournament? Passage 1:The Eagles competed in three tournaments during the 2016–17 season, the first of which took place during the traditional opening of the college hockey season at the 20th annual Ice Breaker Classic. Played on October 7 and 8 at Magness Arena in Denver, Colorado, the tournament showcased the Eagles playing Air Force in the first round, where they would lose a tight 2-1 match. Boston College faced host Denver in the consolation round, picking up a 3-1 victory for their first win of the season. Air Force would defeat Ohio State in the championship. The Eagles had previously won the ice breaker tournament three times; making their fifth appearance this season. The second tournament of the season took place during the holiday break, where the Eagles made the trip to the PPG Paints Arena in Pittsburgh, Pennsylvania for their second appearance in the Three Rivers Classic in its fifth annual year. The Eagles fell 3–1 to the Quinnipiac Bobcats in the opening round, but picked up the 3rd-place result against Ferris State in the consolation round, winning the (unofficial) shootout of the (official) 1–1 tie. Boston College previously won the title in their first appearance at the tournament in 2012. For their final tournament of the season, the Eagles played in the 65th Annual Beanpot Tournament at the TD Garden in Boston, Massachusetts on February 6 and 13. Boston College lost to rival Boston University 3–1 in the opening round (suffering their first season sweep against the Terriers since 1994–95), and were defeated by Northeastern 2–4 in the consolation game, marking the first 4th place finish for the Eagles since 1993 and the first of Jerry York's tenure.
 Passage 2:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.
 Passage 3:When the American Civil War began, Weitzel was assigned to construct defenses, including in Cincinnati and Washington, as well as for George McClellan in the Army of the Potomac in late 1861. He was then attached to the staff of Major General Benjamin F. Butler as chief engineer of the Department of the Gulf. When Union troops captured New Orleans, Weitzel became assistant military commander and acting mayor. He was promoted to brigadier general in August 1862 and two months later routed a large force of the enemy at Labadieville, Louisiana, which earned him a brevet promotion to major in the Regular Army. Weitzel commanded a brigade in the XIX Corps advancing in Major General Nathaniel P. Banks's operations in western Louisiana during April and May 1863, which led to the siege of Port Hudson. Weitzel was later brevetted lieutenant colonel in the Regular Army, "for gallant and meritorious services at the siege of Port Hudson," which fell on July 9, 1863, days after Vicksburg, Mississippi, about 120 miles upriver, the last Confederate stronghold on the great Mississippi, had fallen. Together those successful sieges and the continuing blockage of Southern ports completed the Anaconda Plan.

Question: How many mixtapes did Tinie Tempah release before Krept and Konan were featured on Happy Birthday? Passage 1:More than 300 Roman Catholics were put to death by English governments between 1535 and 1681 for treason, thus for secular rather than religious offenses. In 1570, Pope Pius V issued his papal bull Regnans in Excelsis, which absolved Catholics from their obligations to the government. This dramatically worsened the situation of the Catholics in England. English governments continued to fear the fictitious Popish Plot. The 1584 Parliament of England, declared in "An Act against Jesuits, seminary priests, and such other like disobedient persons" that the purpose of Jesuit missionaries who had come to Britain was "to stir up and move sedition, rebellion and open hostility". Consequently, Jesuit priests like Saint John Ogilvie were hanged. This somehow contrasts with the image of the Elizabethan era as the time of William Shakespeare, but compared to the antecedent Marian Persecutions there is an important difference to consider. Mary I of England had been motivated by a religious zeal to purge heresy from her land, and during her short reign from 1553 to 1558 about 290 Protestants had been burned at the stake for heresy, whereas Elizabeth I of England "acted out of fear for the security of her realm."
 Passage 2:The ancient Egyptians began dividing the night into  at some time before the compilation of the Dynasty V Pyramid Texts in the 24thcentury. By 2150 (Dynasty IX), diagrams of stars inside Egyptian coffin lids—variously known as "diagonal calendars" or "star clocks"—attest that there were exactly 12 of these. Clagett writes that it is "certain" this duodecimal division of the night followed the adoption of the Egyptian civil calendar, usually placed on the basis of analyses of the Sothic cycle, but a lunar calendar presumably long predated this and also would have had twelve months in each of its years. The coffin diagrams show that the Egyptians took note of the heliacal risings of 36 stars or constellations (now known as "decans"), one for each of the ten-day "weeks" of their civil calendar. (12 sets of alternate "triangle decans" were used for the 5 epagomenal days between years.) Each night, the rising of eleven of these decans were noted, separating the night into twelve divisions whose middle terms would have lasted about 40minutes each. (Another seven stars were noted by the Egyptians during the twilight and predawn periods, although they were not important for the hour divisions.) The original decans used by the Egyptians would have fallen noticeably out of their proper places over a span of several centuries. By the time of (), the priests at Karnak were using water clocks to determine the hours. These were filled to the brim at sunset and the hour determined by comparing the water level against one of its twelve gauges, one for each month of the year. During the New Kingdom, another system of decans was used, made up of 24 stars over the course of the year and 12 within any one night.
 Passage 3:In 2011, they released a cover of Jay-Z's and Kanye West's "Otis" which helped them rise to fame. The video reached five million views in its first five days of being uploaded to YouTube. However, with much pressure received from Jay-Z's legal team the video was removed from the duo's profile. Undeterred by the controversy, they released a cover of Drake and Lil Wayne's "The Motto", launched their own clothing line called Play Dirty and early into 2012 were invited to join the British rapper Skepta on his tour in the UK. They appeared on Tinie Tempah's 2011 mixtape Happy Birthday and in 2013 they released their third mixtape Young Kingz, with features from Chip, Tinie Tempah, G FrSH, Giggs, George the Poet, Yungen, Ari, Yana Toma, Fekky, Siah and Anthony Thomas. The album's promotional single "Don't Waste My Time" rose to fame in January 2014, with notable artists such as French Montana, Wretch 32, Chip, G FrSH, Double S, Lady Leshurr, Yungen, Sneakbo MNEK, Dru Blu, Jacob Banks and Dot Rotten all contributing to remixes of the track. Tinie Tempah also freestyled over the beat on Charlie Sloth's Fire in the Booth.

Question: How old was Bela Von Kehrling when Hungary lost their first semifinal to Great Britain? Passage 1:On 11 November, Diversity conducted several hours of signing autographs and posing for photographs with thousands of fans at The Galleria Shopping Centre in Hatfield, Hertfordshire. Afterwards, they hosted a prize-giving ceremony on stage and performed their "Michael Jackson" dance routine. They performed another Michael Jackson tribute at the MOBO award ceremony. Diversity "launched" Christmas at Lakeside on 1 November, where they took two members of the audience on-stage for a dance-off. There was a competition held in November, and a hundred people won a meet and greet with Diversity on 19 November at The Glades in Bromley. On 7 December, Diversity performed on the Royal Variety Performance, hosted in Blackpool and shown on ITV across the UK on 16 December. On the show Got to Dance Warm Up, they presented their Westfield Shopping Centre FlashMob, sponsored by T-Mobile.
 Passage 2:Hungary competed in its first Davis Cup in 1924 and was stuck in the first round for five years (not counting an automatic bye). They broke the curse with the first and convincing 5–0 win against Norway realized by Béla Von Kehrling in the major part. In 1929 they cruised to their first semifinal losing to Great Britain in a close 3–2 (two singles absolved by Von Kehrling) falling only in the fifth rubber. It took another 20 years to relive the success in 1949 (including the five-year vacancy period during the Second World War) this time losing to France in the semis. The core of the team was 1947 French Open champion József Asbóth. In 1956 Hungary was absent from the Cup because of the Hungarian Revolution of 1956. In 1966 a record attendance visited the Hungary-Great Britain quarterfinal in Budapest, where a crowd of 20,000 spectators supported the András Szikszay-István Gulyás Davis Cup team during the four-day tie. A tough weekend started on Saturday 14 May for the multiple champions Brits, who had three-time Major semifinalist Mike Sangster losing their first match in five sets to István Gulyás. They turned to 2–1 on the same day but on Sunday András Szikszay also defeated Sangster leaving the decision to the fifth final tie, which was postponed to Monday. In a four set match Gulyás started well taking the first one 18–16, but Roger Taylor finished in three easier sets. English team captain Headley Baxter remarked that although they won they hadn't been forced into such a tough fight for years. Just two weeks later Gulyás had his first and lone Grand Slam final in the French Open losing only to Tony Roche of Australia.
 Passage 3:McIlroy was born in Lambeg, County Antrim and he was introduced to football at an early age as his father, Harry played for Lisburn Distillery and his uncle, Willie played for Portadown. After leaving school McIlroy played for Glentoran before joining Burnley in March 1950 for £7,000. He soon cemented his reputation as one of the finest scheming inside forwards since World War II. He was dubbed as the 'Brain' of Burnley and was a very composed passer of the ball only releasing it when he was sure of finding a teammate. His neat footwork made him a crowd favourite at Turf Moor and indeed for the Northern Ireland national team where he made 55 caps. He helped Burnley win the First Division in 1959–60 and reach the FA Cup Final in 1962, losing 3–1 to Tottenham Hotspur. After 497 matches for the "Clarets" scoring 131 goals, McIlory was allowed to leave for Stoke City for a cut price £25,000, which came as a shock to the Burnley fans who branded chairman Bob Lord 'insane'.
