Example Input: Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?
Example Output: Broderick.

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: The museum's founder Sigurður Hjartarson worked as a teacher and principal for 37 years, teaching history and Spanish at Reykjavík's Hamrahlid College for the last 26 years before his retirement. As a child, he owned a bull's pizzle, which was given to him to use as a cattle whip. He began collecting penises after a friend heard the story of the bull's penis in 1974 and gave him four new ones, three of which Sigurður gave to friends. Acquaintances at whaling stations began bringing him whale penises as well, and the collection grew from there, expanding through donations and acquisitions from various sources around Iceland.The organs of farm animals came from slaughterhouses, while fishermen supplied those of pinnipeds and the smaller whales. The penises of larger whales came from commercial whaling stations, although this source dried up after the International Whaling Commission implemented a global ban on commercial whaling in 1986. Sigurður was able to continue to collect whale penises by harvesting them from the 12–16 whales that fall victim to stranding on the Icelandic coast each year. He also obtained the penis of a polar bear shot by fishermen who found the animal drifting on drift ice off the Westfjords.Sigurður was assisted by his family, though not without some occasional embarrassment. His daughter Þorgerður recalls that she was once sent to a slaughterhouse to collect a specimen but arrived just as the workers were taking a lunch break: "Someone asked, 'What's in the basket?' I had to say, 'I'm collecting a frozen goat penis.' After that I said, 'I will never collect for you again.'" According to Sigurður, "Collecting penises is like collecting anything. You can never stop, you can never catch up, you can always get a new one, a better one."
The collection was at first housed in Sigurður's office at the college until he retired from his teaching job. He decided, more as a hobby than a job, to put it on public display in Reykjavík and was awarded a grant from the city council of ISK 200,000 to support the opening of a museum in August 1997. By 2003, it was attracting 5,200 visitors a year, of which 4,200 were from abroad. He put the museum up for sale in 2003, but also offered it to the city of Reykjavík as a gift. However, he was unsuccessful in obtaining financial support from the state or city. When he retired in 2004, he could no longer afford the rent on the museum's premises. 
Question: What is the last name of the person who also obtained the penis of a polar bear shot by a fisherman?
Example Output:
Hjartarson.
