Passage: In 1933, a child orphaned during the Ukrainian Holodomor runs away from his orphanage and is taken in by a Red Army unit and adopted by its kindly commander, who gives him the name Leo Demidov. In 1945, now a sergeant with the unit, Leo  becomes an icon across the Soviet Union when he is photographed planting the Soviet flag atop the Reichstag during the Battle of Berlin. He becomes a Hero of the Soviet Union.
In 1953, Leo, now married to Raisa and living in Moscow, is a captain in the Ministry of State Security, commanding a unit tasked with tracking down and arresting dissidents. They arrest a veterinarian, Anatoly Brodsky, and during the arrest, one of Leo's subordinates, the cowardly but ambitious Vasili Nikitin, shoots a farmer, Semyon Okun, and his wife in whose barn Brodsky has been hiding, orphaning their two young daughters. Angry, Leo strikes Vasili, who harbours growing resentment against Leo and the other officer in the unit, Alexei Andreyev; all three were in Berlin together in 1945. Vasili is in charge of Brodsky's interrogation and execution, and one of the names he gives to their superior, Major Kuzmin, is that of Raisa, a primary school teacher, several of whose colleagues have recently been arrested for dissident views. Kuzmin orders Leo to investigate his own wife.
Meanwhile, Alexei's young son, Jora, is found dead near a railway yard. Although the initial pathology report shows injuries consistent with torture, the surgically precise removal of organs, and drowning, the authorities declare that he was hit by a train, as Stalin has decreed that murder is a capitalist disease; there is no murder in a communist paradise. Alexei is forced to accept the official conclusions to save himself and the rest of his family. 
Question: What is the profession of the man that the person in Leo's unit interrogates?

Ex Output:
veterinarian.

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?

Ex Output:
wealthy, land-owning families.

Passage: On October 1, 2007, Columbia Records released the triple CD retrospective album Dylan, anthologising his entire career under the Dylan 07 logo. As part of this campaign, Mark Ronson produced a re-mix of Dylan's 1966 tune "Most Likely You Go Your Way and I'll Go Mine", which was released as a maxi-single. This was the first time Dylan had sanctioned a re-mix of one of his classic recordings.The sophistication of the Dylan 07 marketing campaign was a reminder that Dylan's commercial profile had risen considerably since the 1990s. This first became evident in 2004, when Dylan appeared in a TV advertisement for Victoria's Secret lingerie. Three years later, in October 2007, he participated in a multi-media campaign for the 2008 Cadillac Escalade. Then, in 2009, he gave the highest profile endorsement of his career, appearing with rapper will.i.am in a Pepsi ad that debuted during the telecast of Super Bowl XLIII. The ad, broadcast to a record audience of 98 million viewers, opened with Dylan singing the first verse of "Forever Young" followed by will.i.am doing a hip hop version of the song's third and final verse.In October 2008, Columbia released The Bootleg Series Vol. 8 – Tell Tale Signs as both a two-CD set and a three-CD version with a 150-page hardcover book. The set contains live performances and outtakes from selected studio albums from Oh Mercy to Modern Times, as well as soundtrack contributions and collaborations with David Bromberg and Ralph Stanley. The pricing of the album—the two-CD set went on sale for $18.99 and the three-CD version for $129.99—led to complaints about "rip-off packaging" from some fans and commentators. The release was widely acclaimed by critics. The abundance of alternative takes and unreleased material suggested to one reviewer that this volume of old outtakes "feels like a new Bob Dylan record, not only for the astonishing freshness of the material, but also for the incredible sound quality and organic feeling of everything here.". 
Question: The pricing of which album led to complaints about "rip-off packaging"?

Ex Output:

The Bootleg Series Vol. 8 – Tell Tale Signs.
