Example Input: Passage: Seattle was awarded a Major League Baseball franchise, the Seattle Pilots, in 1969. The team played at Sick's Stadium in Mount Baker for one season before relocating to Milwaukee and becoming the Milwaukee Brewers. The city, county, and state governments sued the league and was offered a second expansion team, the Seattle Mariners, who began play at the Kingdome in 1977. The Mariners struggled in the stadium and moved to a purpose-built baseball stadium, T-Mobile Park (formerly Safeco Field), in 1999. The Mariners have never reached a World Series and only appeared in the MLB playoffs four times, all between 1995 and 2001, despite having Hall of Fame players and candidates like Ken Griffey Jr., Randy Johnson, Ichiro, and Alex Rodriguez. The team tied the all-time single regular season wins record in 2001 with 116 wins. Since 2001, the Mariners have failed to qualify for the playoffs—the longest active postseason drought in North American sports, at 17 seasons.
From 1967 to 2008 Seattle was also home to a National Basketball Association (NBA) franchise: the Seattle SuperSonics, who were the 1978–79 NBA champions. The SuperSonics relocated to Oklahoma City and became the Oklahoma City Thunder for the 2008–09 season.The Major League Baseball All-Star Game was held in Seattle twice, first at the Kingdome in 1979 and again at Safeco Field in 2001. The NBA All-Star Game was also held in Seattle twice: the first in 1974 at the Seattle Center Coliseum and the second in 1987 at the Kingdome.Seattle also boasts two collegiate sports teams based at the University of Washington and Seattle University, both competing in NCAA Division I for various sports. The University of Washington's athletic program, nicknamed the Huskies, competes in the Pac-12 Conference, and Seattle University's athletic program, nicknamed the Redhawks, mostly competes in the Western Athletic Conference. The Huskies teams use several facilities, including the 70,000-seat Husky Stadium for football and the Hec Edmundson Pavilion for basketball and volleyball. The two schools have basketball and soccer teams that compete against each other in non-conference games and have formed a local rivalry due to their sporting success.The Seattle Thunderbirds hockey team plays in the Canadian major-junior Western Hockey League and are based in the Seattle suburb of Kent. Seattle successfully applied for a new expansion team with the National Hockey League, which will make its first appearance in 2021. Seattle plans to renovate KeyArena to use for the possible NHL team. On March 1, 2018, a ticket drive began to gauge interests in season ticket deposits. Oak View reported that their initial goal of 10,000 deposits was surpassed in 12 minutes, and that they received 25,000 deposits in 75 minutes. 
Question: What arena will the city that held the NBA All-Star game twice renovate for possible use for an NHL expansion team?
Example Output: KeyArena.

Example Input: Passage: Although weakened and pushed south beyond the Huai River, the Southern Song found new ways to bolster its strong economy and defend itself against the Jin dynasty. It had able military officers such as Yue Fei and Han Shizhong. The government sponsored massive shipbuilding and harbor improvement projects, and the construction of beacons and seaport warehouses to support maritime trade abroad, including at the major international seaports, such as Quanzhou, Guangzhou, and Xiamen, that were sustaining China's commerce.To protect and support the multitude of ships sailing for maritime interests into the waters of the East China Sea and Yellow Sea (to Korea and Japan), Southeast Asia, the Indian Ocean, and the Red Sea, it was necessary to establish an official standing navy. The Song dynasty therefore established China's first permanent navy in 1132, with a headquarters at Dinghai. With a permanent navy, the Song were prepared to face the naval forces of the Jin on the Yangtze River in 1161, in the Battle of Tangdao and the Battle of Caishi. During these battles the Song navy employed swift paddle wheel driven naval vessels armed with traction trebuchet catapults aboard the decks that launched gunpowder bombs. Although the Jin forces commanded by Wanyan Liang (the Prince of Hailing) boasted 70,000 men on 600 warships, and the Song forces only 3,000 men on 120 warships, the Song dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddle wheel ships. The strength of the navy was heavily emphasized after that. A century after the navy was founded it had grown in size to 52,000 fighting marines.
The Song government confiscated portions of land owned by the landed gentry in order to raise revenue for these projects, an act which caused dissension and loss of loyalty amongst leading members of Song society but did not stop the Song's defensive preparations. Financial matters were made worse by the fact that many wealthy, land-owning families—some of which had officials working for the government—used their social connections with those in office in order to obtain tax-exempt status.Although the Song dynasty was able to hold back the Jin, a new foe came to power over the steppe, deserts, and plains north of the Jin dynasty. The Mongols, led by Genghis Khan (r. 1206–1227), initially invaded the Jin dynasty in 1205 and 1209, engaging in large raids across its borders, and in 1211 an enormous Mongol army was assembled to invade the Jin. The Jin dynasty was forced to submit and pay tribute to the Mongols as vassals; when the Jin suddenly moved their capital city from Beijing to Kaifeng, the Mongols saw this as a revolt. Under the leadership of Ögedei Khan (r.1229–1241), both the Jin dynasty and Western Xia dynasty were conquered by Mongol forces. The Mongols also invaded Korea, the Abbasid Caliphate of the Middle East and the Kievan Rus'. 
Question: What people used their social connections with those in office in order to obtain tax-exempt status?
Example Output: wealthy, land-owning families.

Example Input: Passage: Paul is a young womanizer living in a small Southern town, where he earns a living fixing cars for his uncle. Paul still lives with his mother, Elvira, who works as a clown cheering up children at the local hospital. He spends most of his time hanging out with his best friend and self-proclaimed partner-in-crime, Tip, and their friends Bo and Bust-Ass. Among his friends, Paul has a reputation as a ladies' man, but he is not at all known for being involved with long-term relationships; most of Paul's romances last only a few weeks, and he's slept with nearly every girl in town. Paul is beginning to reach a point where he would like to lead a different life, and that feeling becomes all the more clear when he meets Noel, Tip's teenage sister who returns home after attending a boarding school. Noel is more thoughtful and mature than the girls Paul is used to. Paul and Noel soon fall in love, but for Paul this is a different sort of relationship than he's accustomed to — Noel is still a virgin, and her contemplative nature gives him a desire to be a better, stronger person, but Tip does not approve of Paul dating his younger sister, which leads to a rift between these longtime friends. 
Question: Who are Bo, Bust-Ass and Tip friends with?
Example Output:
Paul.
