[EX Q]: 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 A]: wealthy, land-owning families.

[EX Q]: Passage: The film opens with "The Super Fan", an avid Chiefs fan, making his 3rd belt. The film depicts the lives of 5 Chiefs players: Mike Bajurny (brother of producer David Bajurny), Brady Austin, Mike Henderson and Cory Holland.
With the exception of Henderson, all of these players live in an abandoned storage area on the second story of Colisée de Laval, affectionately known as "The Rat's Nest". Several players discuss the living conditions. Some don't mind it, while other say that since the room is near an exit, the apartments will not be used for a fire exit. Henderson mentions that the living situation isn't bad for a young single guy.
Henderson discusses his role with the team. He doesn't think he is limited to being a fighter, but considers himself to have an Owen Nolan-type of role with the team, where he could be tough as needed.
The Super Fan shows how he prepares for a big game: which involves the shining of one of his championship belts.  A shot of the arena is shown with fans mock-fighting each other with security surrounding the ice. Craig Martin discusses a line brawl and how it originated. At the end of the second, the team was trailing 3-0, but the Chiefs would score 7 goals to come back and win.
Families of the players discuss their son's and boyfriend's role with the team. Bajurny's mother does not approve of her son's role as a fighter. Henderson's fiancé discusses how they met and how she feels about him playing professional hockey.
A 6'5", 265 lbs ex-military strong man by the name of Tim Leveque comes to play for the Chiefs. The players discuss Tim coming to the team, and some players are concerned about not knowing his background. He immediately establishes himself as an enforcer. He is shown fighting 6'7", 320 lb Dominic "The Giant" Forcier and beats him. 
Question: What is the first name of the player whose background the team doesn't know much about?
[EX A]: Tim.

[EX Q]: Passage: In an undercover mission, Major Sloane kills Professor Ragheeb, an ancient hieroglyphics expert at Oxford University and steals a hieroglyph-encrypted message. Sloane then asks Professor David Pollock, who has taken over Ragheeb's class on Hieroglyphics, to meet with shipping magnate Nejim Beshraavi on a business matter. David declines but changes his mind after being forced to enter a Rolls-Royce Phantom IV, where he meets Middle Eastern Prime Minister Hassan Jena and his Ambassador to Great Britain, Mohammed Lufti. Jena asks David to accept Beshraavi's offer of employment.
David meets Beshraavi, who asks him to decode the inscription on the piece of paper Sloane stole. David is attracted to Beshraavi's girlfriend Yasmin Azir, who tells him that Beshraavi had Ragheeb killed and will do the same to him once he decodes the message. Their conversation is interrupted by Beshraavi. David keeps hidden until Sloane brings it to Beshraavi's attention that David and the cipher are missing. Overhearing the conversation, David wraps the cipher in a candy in his pocket, among others, a red one with the number "9". As Beshraavi's men search for David, Beshraavi demonstrates to one of Yasmin's employees, Hemsley, that he can buy people for their loyalty or else exact extreme revenge.  Forced to show himself, David seemingly abducts Yasmin. They flee from one of Beshraavi's henchmen, Mustapha. In the course of the chase, Mustapha and David struggle at the zoological gardens, when another man intervenes and kills Mustapha. He identifies himself as Inspector Webster with CID. When a guard approaches, Webster kills him before revealing that he is working with Yasmin. Webster knocks David unconscious. 
Question: Who kills Mustapha?
[EX A]:
Inspector Webster.
