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.

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.

Passage: Following the purchase of two of his paintings by the Prussian Crown Prince, Friedrich was elected a member of the Berlin Academy in 1810. Yet in 1816, he sought to distance himself from Prussian authority and applied that June for Saxon citizenship. The move was not expected; the Saxon government was pro-French, while Friedrich's paintings were seen as generally patriotic and distinctly anti-French. Nevertheless, with the aid of his Dresden-based friend Graf Vitzthum von Eckstadt, Friedrich attained citizenship, and in 1818, membership in the Saxon Academy with a yearly dividend of 150 thalers. Although he had hoped to receive a full professorship, it was never awarded him as, according to the German Library of Information, "it was felt that his painting was too personal, his point of view too individual to serve as a fruitful example to students." Politics too may have played a role in stalling his career: Friedrich's decidedly Germanic subjects and costuming frequently clashed with the era's prevailing pro-French attitudes.

Ex Output:
What is the first name of the man that the Dresden-based person helped attain membership into the Saxon Academy?
