Question: How long did Aulus Plautius live after capturing the lands south of the River Trent? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
 Passage 2:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frédéric Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wüllner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
 Passage 3:Kevin Francis (born June 5, 1993) is a professional Canadian football linebacker for the Ottawa Redblacks of the Canadian Football League (CFL). After going undrafted in the 2016 NFL draft, Francis declared eligible for the 2016 CFL Supplemental Draft after informing the league that he was born in Toronto, Ontario. He was drafted by the Roughriders on May 26, 2016, who forfeited a third round selection in the 2017 CFL Draft to acquire his rights. Upon entering 2016 training camp, Francis switched to the defensive side of the ball after playing as a tight end during his college football career with the North Carolina A&T Aggies. He made his CFL debut on June 30, 2016 against the Toronto Argonauts, registering his first defensive tackle. Francis finished his rookie season leading the team in special team tackles, also being ranked 7 on the CFL rising sophomore list

Question: What was the size of Princeton's endowment the year Beale was born? Passage 1:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
 Passage 2:Beale was born in 1948 in St. Louis County, Minnesota to C. Gordon Beale, a minister of the United Church of Christ, and Marcella Beale, a nurse. He served in the United States Army as a medic in the early 1970s and was honorably discharged. Beale attended the University of California, Riverside, earning a bachelor's degree in political science in 1975, using resources provided by the G.I. Bill. Beale interned for Democrat US Senator John V. Tunney while in college, assisting in the negotiation of the Bilingual Courts Act. He later simultaneously earned a Master of Public Administration from Princeton University and a law degree from New York University. Beale was employed with a law firm consisting of three partners in Lake City, Minnesota for four years prior to his work with the EPA. During his time with this law firm, he primarily dealt with the Federal Election Commission and the Securities and Exchange Commission.
 Passage 3:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."
