Question: Is the driver who passed the pole-sitter ten laps into the race older than the drive he passed? Passage:Ten laps into the race, Michael Waltrip passed pole-sitter Jeff Gordon for the lead. On Lap 19, the caution flag was thrown after a multi-car accident. Waltrip continued leading until Lap 55, in which Dale Earnhardt Incorporated teammate Dale Earnhardt, Jr. After Bobby Hamilton, Jr. had an accident on Lap 70, Earnhardt led the race into pit road, but was pushed out by Gordon and Brian Vickers, and fell to fifteenth, giving Mike Wallace the lead entering Lap 74. Shepherd pitted on the following lap, and Morgan Shepherd took the lead. However, Shepherd would later pit, as Gordon regained the lead. Waltrip then retook the lead from Gordon on Lap 86, though Gordon then took the lead again 13 laps later. Ten laps later, Gordon pitted, and Waltrip was given the lead. On the ensuing lap, Earnhardt took the lead, though he later pitted, and Jimmy Spencer gained the lead. On Lap 113, Spencer lost the lead to Gordon when he pitted, who led the pit stops on Lap 139. Dave Blaney stayed out, and took the lead, though Ryan Newman gained first-place when Blaney went to pit road. Newman pitted on Lap 143, giving Tony Stewart the lead. With ten laps left in the race, Hendrick Motorsports teammates Jeff Gordon and Jimmie Johnson followed in third and fourth, respectively, behind Tony Stewart and Dale Earnhardt, Jr. Johnson then pushed Gordon past Stewart and Earnhardt, and Gordon subsequently won, his fourth of the season and second consecutive. The victory by Gordon made him the first driver since Cale Yarborough to win the Pepsi 400 from the pole. A version of the race's waning moments was included in the prologue of the video game , which involved Johnson pushing Gordon past Earnhardt.

Question: When was the person who designed the new campus born? Passage:Consequently, in 1870, it moved to a (then greenfield) site on Gilmorehill in the West End of the city, around three miles (5 km) west of its previous location, enclosed by a large meander of the River Kelvin. The original site on the High Street was sold to the City of Glasgow Union Railway and replaced by the College goods yard. The new-build campus was designed by Sir George Gilbert Scott in the Gothic revival style. The largest of these buildings echoed, on a far grander scale, the original High Street campus's twin-quadrangle layout, and may have been inspired by Ypres' late medieval cloth hall; Gilmorehill in turn inspired the design of the Clocktower complex of buildings for the new University of Otago in New Zealand. In 1879, Gilbert Scott's son, Oldrid, completed this original vision by building an open undercroft forming two quadrangles, above which is his grand Bute Hall (used for examinations and graduation ceremonies), named after its donor, John Crichton-Stuart, 3rd Marquess of Bute. Oldrid also later added a spire to the building's signature gothic bell tower in 1887, bringing it to a total height of some . The local Bishopbriggs blond sandstone cladding and Gothic design of the building's exterior belie the modernity of its Victorian construction; Scott's building is structured upon what was then a cutting-edge riveted iron frame construction, supporting a lightweight wooden-beam roof. The building also forms the second-largest example of Gothic revival architecture in Britain, after the Palace of Westminster. An illustration of the Main Building currently features on the reverse side of the current series of £100 notes issued by the Clydesdale Bank.

Question: How old was Oliver Humperdink the year Roberston won the NWA Central States Television Championship? Passage: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.
