In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Example Input: 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).

Example Input: Passage: Walter Rowley's "Trotters" finished in 17th place in 1947–48, 14th place in 1948–49, and 16th place in 1949–50. He scored six goals in 93 league games during his spell at Burnden Park. McShane joined Manchester United in exchange for defender John Ball and £5,000 in September 1950. He was signed to replace the departing Charlie Mitten. He scored seven goals in 31 appearances in the 1950–51 season, as the "Red Devils" finished second in the league. His first goal at Old Trafford came on 7 October 1950, in a 3–1 win over Sheffield Wednesday. He was part of the United side that won the First Division title in 1951–52, scoring one goal in 12 league games that season. His goal was an important one, as it came against rivals Manchester City in a 2–1 win at Maine Road on 15 September. He then struggled with a cartilage injury, and appeared just five times in the 1952–53 campaign, as Matt Busby's side dropped to eighth place.
 Link Information: Burnden Park was the home of English football club Bolton Wanderers who played home games there between 1895 and 1997. Question: When was the place founded where Harry McShane scored 6 goals in 93 league games?

Example Input: Passage: Giovanna married Tsar Boris III of Bulgaria in the Basilica of St Francis of Assisi, Assisi in October 1930, in a Roman Catholic ceremony, attended by Italian dictator Benito Mussolini. Bulgarians deemed her a good match, partly because her mother, Elena of Montenegro, was of Slavic ethnicity. At a second ceremony in Sofia, Giovanna (who herself was daughter of a Roman Catholic father and a formerly Orthodox mother) was married in an Eastern Orthodox Church ceremony, bringing her into conflict with the Roman Catholic Church. Giovanna adopted the Bulgarian version of her name, Ioanna. Giovanna knew the Pope's Apostolic Visitor to Bulgaria, Archbishop Angelo Roncalli, the future Pope John XXIII who was able to help her. She and Boris had two children: Marie Louise of Bulgaria, born in January 1933, and then the future Simeon II of Bulgaria in 1937.
