In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Sergeant First Class Buck McGriff and Sergeant First Class Albaby Perkins are two joint services Criminal Investigation Division agents on duty in war torn Saigon.  When a prostitute is found murdered they discover that the prime suspects are high ranking U.S. Army officers.  As they investigate they find that there have been a string of at least six murders in the last year, but the previous inquiry was shut down from higher up the chain of command. Investigations lead them to Colonel Dexter Armstrong, but Armstrong rules himself out of inquiries by committing suicide. With the help of a French nun Sister Nicole and their non-commissioned officer in charge, Master Sergeant Dix, they finally close in on their target. As their investigation leads them closer and closer to the murderer, they find their lives are in danger and they end up nearly being sent home. The movie ends with an unexpected twist when they rule out all their suspects by conducting an interview in a Viet Cong tunnel base, and their NCO is the killer.
What is the full name of the characters who learn of a string of six murders?

Passage: A young woman in labour makes her way to a parish workhouse and dies after giving birth to a boy, who is systematically named Oliver Twist by the workhouse authorities. As the years go by, Oliver and the rest of the child inmates suffer from the callous indifference of the officials in charge: beadle Mr. Bumble and matron Mrs. Corney. At the age of nine, the hungry children draw straws; Oliver loses and has to ask for a second helping of gruel ("Please sir, I want some more").
For his impudence, he is promptly apprenticed to the undertaker Mr. Sowerberry, from whom he receives somewhat better treatment. However, when another worker, Noah, maligns his dead mother, Oliver flies into a rage and attacks him, earning the orphan a whipping.
Oliver runs away to London. The Artful Dodger, a skilled young pickpocket, notices him and takes him to Fagin, an old Jew who trains children to be pickpockets. Fagin sends Oliver to watch and learn as the Dodger and another boy try to rob Mr. Brownlow, a rich, elderly gentleman. Their attempt is detected, but it is Oliver who is chased through the streets by a mob and arrested. A witness clears him. Mr. Brownlow takes a liking to the boy, and gives him a home. Oliver experiences the kind of happy life he has never had before, under the care of Mr. Brownlow and the loving housekeeper, Mrs. Bedwin.
Meanwhile, Fagin is visited by the mysterious Monks, who has a strong interest in Oliver. He sends Monks to Bumble and Mrs. Corney (now Bumble's domineering wife); Monks buys from them the only thing that can identify Oliver's parentage, a locket containing his mother's portrait.
What is the full name of the person who asks "Please sir, I want some more"?

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'.
