[EX Q]: Question: Which college where Harben was educated has the highest enrollment? Passage 1:The towers were designed as framed tube structures, giving tenants open floor plans, unobstructed by columns or walls. The framed tube design was introduced by Bangladeshi-American structural engineer Fazlur Rahman Khan in the 1960s. The design was accomplished by using many closely spaced perimeter columns, providing much of the structure's strength, with the gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be used for office purposes by making the structural core smaller. The design and construction of the towers involved many other innovative techniques, such as wind tunnel experiments and the slurry wall for digging the foundation. Yamasaki also incorporated elements of Islamic architecture in the building's design, having previously designed Saudi Arabia's Dhahran International Airport with the Saudi Binladin Group.
 Passage 2:Beagle is a crater lying within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars, the crater is one of multiple topographical depressions within the Meridiani Planum extraterrestrial plain, which was explored by the Opportunity rover. It was located by the rover in images taken on sol 855 (June 20, 2006), 310 metres (1,107 ft) away. It is on the edge of the much larger ejecta blanket surrounding the crater Victoria, named the Victoria Annulus. This impact crater was named in honor of HMS Beagle of the Royal Navy, ordered in February 1817, which carried Charles Darwin on his voyage round the world.
 Passage 3:He was the son of Henry Andrade Harben and the grandson of Sir Henry Harben who founded Prudential Assurance, Harben was educated at Eton College and Magdalen College, Oxford, before qualifying as a barrister. He married Agnes Helen Bostock. He stood unsuccessfully for the Conservative Party in Eye at the 1900 general election, but by 1902 had switched his affiliation to the Liberal Party. He stood for the Liberal Party in Worcester at the 1906 general election. Although he lost the election, he petitioned the election court on the grounds that supporters of the winner, George Henry Williamson, had engaged in widespread bribery. He won the case, but the seat was left vacant until a by-election in 1908, and the local Liberal Party adopted a new candidate. Harben next stood in Portsmouth at the December 1910 general election, but came bottom of the poll.

[EX Q]: Question: How old was Michael Andretti the year that he joined Team Motorola? Passage 1:Traditional African religions like the Serer religion (A ƭat Roog) are adhered to by devout worshippers of Roog – the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.
 Passage 2:At the 1988 King of the Ring tournament, Bass qualified for the final after beating a young Shawn Michaels but was paid by Ted DiBiase to fake an injury. Bass began a feud with Beefcake in August 1988, gouging Beefcake's head open with his spurs ("Bret" and "Bart") on an episode of Superstars of Wrestling; the attack caused Beefcake to miss his scheduled Intercontinental championship match against the Honky Tonk Man at the first SummerSlam event on August 29. Bass and Honky co-captained a five-man contingent against a team captained by Beefcake and the Ultimate Warrior at the second Survivor Series in November. Bass and teammate Greg Valentine were eliminated by Warrior in succession in the final minute of the match. On the January 7, 1989 Saturday Night's Main Event XIX, Bass lost to Beefcake via sleeperhold in a hair vs. hair match. He competed in the 1989 Royal Rumble (sans hair), Bass' feud with Beefcake was scrapped, and he was used mainly as a preliminary wrestler and left the WWF shortly thereafter.
 Passage 3:In 1994, Green joined his brother Barry's Team Green as team manager, and competed in the 1994 CART IndyCar World Series with driver Jacques Villeneuve, eventually winning both the 1995 Indianapolis 500 and the CART PPG IndyCar World Series Cup that same year. In 1996 Team Green became known as the Brahma Sports Team for a season, with driver Raul Boesel. In 1997 KOOL cigarettes took over as a major sponsor with Parker Johnstone, and the team was renamed Team KOOL Green, before expanding to a two-car effort in 1998 with Paul Tracy and rising youngster Dario Franchitti. In 2001, Michael Andretti joined the team in a separate effort headed by Kim Green, known as Team Motorola. In July 2002, Andretti purchased a controlling stake in the team which became Andretti Green Racing. Shortly thereafter the team moved to the IRL IndyCar Series where it won league championships in 2004, 2005 and 2007 and the Indianapolis 500 in 2005 and 2007. Green and fellow co-owner Kevin Savoree left AGR in September 2009 to run Green Savoree Racing Promotions, an auto race promotion company. Currently, GSRP promote Indycar Series races in St. Petersburg, Florida and Toronto, Ontario, Canada. On March 2, 2011 Green Savoree purchased the Mid-Ohio Sports Car Course and will promote races at that site as well.

[EX Q]: Question: How long had The Observer been operating as a going concern the year Harrisson started working there as a radio critic? Passage 1:During April 5, 2017, the Fiji Meteorological Service started to monitor Tropical Disturbance 20F that had developed about to the northwest of the Fijian dependency of Rotuma. The system lied within an area of favourable conditions for further development with low to moderate vertical wind shear and warm sea surface temperatures of about . Over the next couple of days, the system moved south-westwards and gradually developed further, before it was classified as a tropical depression by the FMS during April 7. The United States Joint Typhoon Warning Center (JTWC) subsequently issued a Tropical Cyclone Formation Alert on the disturbance, as atmospheric convection consolidated around the system's elongated low level circulation center. During that day, the system was steered south-westwards towards Vanuatu and New Caledonia, by northeasterly winds located to the northwest of a subtropical ridge of high pressure. The system subsequently passed near or over the islands of Maewo and Ambae, before the JTWC initiated advisories on the depression and designated it as Tropical Cyclone 16P early on April 8. The system subsequently passed near or over Malakula, before the FMS reported that it had developed into a Category 1 tropical cyclone, on the Australian tropical cyclone intensity scale and named it Cook.
 Passage 2:Channel 4 was in danger of losing its NBC affiliation when Westinghouse balked at NBC's initial offer to trade sister stations KYW radio and WPTZ television (now KYW-TV) in Philadelphia in exchange for WTAM-AM-FM and WNBK television (now WKYC-TV) in Cleveland. In response, NBC threatened to pull its programming from both WBZ-TV and WPTZ unless Westinghouse agreed to the trade. The swap was made in February 1956, but Westinghouse immediately complained to the Federal Communications Commission (FCC) and the U.S. Department of Justice about NBC's extortion. The threat reemerged in 1960 after NBC announced it would swap the Philadelphia stations in exchange for a competing Boston outlet, then-CBS affiliate WNAC-TV (channel 7) and its sister radio stations, from RKO General. Approval of the RKO-NBC deal would have potentially made WBZ-TV an ABC affiliate, completing a three-way swap of network affiliations in Boston. However, in 1964, the FCC nullified the NBC-RKO trade and ordered the NBC-Westinghouse swap reversed without NBC realizing any profit on the deal. WBZ-TV retained its NBC affiliation as a result of the canceled sale.
 Passage 3:During the Second World War Harrisson continued directing Mass-Observation and was radio critic for The Observer from May 1942 until June 1944. For much of this time he was in the army and gave up reviewing on leaving the UK. After service in the ranks he was commissioned as a second lieutenant in the Reconnaissance Corps on 21 November 1943. He had been recruited (some sources say by a confusion of names, despite his apparent suitability) for a plan to use the native peoples of Borneo against the Japanese. He was attached to Z Special Unit (also known as Z Force), part of the Services Reconnaissance Department (SRD: a branch of the combined Allied Intelligence Bureau in the South West Pacific theatre). On 25 March 1945, he was parachuted with seven Z Force operatives from a Consolidated Liberator onto a high plateau occupied by the Kelabit people. An autobiographical account of this operation (SEMUT I, one of four SEMUT operations in the area) is given in World Within (Cresset Press, 1959); there are also reports – not always flattering – from some of his comrades. His efforts to rescue stranded American airmen shot down over Borneo are a central part of "The Airmen and the Headhunters", an episode of the PBS television series Secrets of the Dead. The recommendation for his Distinguished Service Order which was gazetted on 6 March 1947 (and dated 2 November 1946) describes how from his insertion until 15 August 1945 the forces under his command protected the flank of Allied advances, and caused severe disruption to Japanese operations.
