[EX Q]: Passage: The Arizona Cardinals National Football League (NFL) franchise is allegedly suffering a curse by the citizens of Pottsville, Pennsylvania for undeservedly claiming the 1925 NFL championship from the Pottsville Maroons who were stripped of their title by the NFL in one of the greatest controversies in sports history. The curse will supposedly only be lifted when the championship is returned to Pottsville and to the correct shade of red team; this can only be met by overturning the original ruling, as Pottsville no longer has an NFL team and is too small to ever receive another one (with a metropolitan area roughly half the population of Green Bay, the league's smallest), making it impossible for the long-defunct Maroons to win another title. The Cardinals team holds the record for the longest championship drought, with their most recent championship coming in 1947, which is also the longest drought in American professional sports; the 1947 team was notable for having two of its members die during their playing careers within a year of each other, with Jeff Burkett dying in a plane crash following appendix surgery during the season and Stan Mauldin dying of a heart attack after a game the following season. Arizona also lost Super Bowl XLIII to another Pennsylvania team: the Pittsburgh Steelers (whose founder Art Rooney supported Pottsville's claim to the title). The franchise also leads the NFL in the total number of losses (730 through the 2017 season).

Link Information: In 1929 the old wooden grandstand was demolished and replaced by a new Main Stand, which was designed by Archibald Leitch, whose influence, the criss-cross lattice work, can still be seen at Ibrox (Rangers), Home Park (Plymouth Argyle) and Goodison Park (Everton). Fragments of the iconic lattice work would later be used to separate parts of the car park at the Stadium of Light. The work on the new Main Stand nearly bankrupted the club. By this time the official capacity of Roker Park was 60,000 Question: What was the seating capacity at Roker Park in 1929?
[EX A]: Answer: 60,000

[EX Q]: Passage: Thado Minbya was born Rahula to Princess Soe Min Kodawgyi of Sagaing and Viceroy Thado Hsinhtein of Tagaung in 1345. From his mother's side, he was a grandson of King Saw Yun, the founder of the Sagaing Kingdom, and nephew of then reigning king Kyaswa as well as a great grandson of King Thihathu of Pinya and King Kyawswa of Pagan. From his father's side, he was descended from a line of hereditary rulers of Tagaung from the House of Thado. According to British colonial period scholarship, his father was an ethnic Shan and his mother was mostly Shan; however some have argued that no extant chronicle or archaeological evidence supports the conjecture. The prince had two younger sisters: Shin Saw Gyi and Saw Omma. His father died soon after the birth of Saw Omma. His mother remarried to Thihapate, a grandnephew of Queen Pwa Saw of Pagan. In 1352, Thihapate became king of Sagaing.
Link Information: After Thihathu's death in 1325, the two kingdoms formally went separate ways, with Pinya controlling southern Upper Burma and Sagaing northern Upper Burma. (Zatadawbon Yazawin and Maha Yazawin chronicles count Saw Yun's official reign at Sagaing only after the death of Thihathu whereas later chronicles Yazawin Thit and Hmannan Yazawin count his reign from his first insurrection in 1315.) Early on, Pinya's new rulers still had designs on Sagaing. Pinya's attempt to assassinate Saw Yun nearly succeeded, stopped only by the assassin Khin Nyo's conscience at the last minute.

Saw Yun was remembered in Burmese chronicles as powerful, kindly and popular. He also contributed to Burmese military. In 1318, Saw Yun formed a cavalry regiment called Sagaing Htaungthin ( ; lit. "Thousand-strong Regiment of Sagaing", although the numbers added up to only 830), which was maintained up till the fall of Burmese monarchy, and nine squadrons of cavalry.

He died 5 February 1327. Question: How long was the reign of Minbya's grandfather?
