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.

Input: Consider Input: Passage: Eric Stoltz plays John Dantley, an NTSB officer sent to O'Hare Airport in Chicago to investigate a collision between Global Airlines Flight 1025 (a Boeing 757-200 from Los Angeles to Washington D.C.) and PDO Cargo flight 342 (a Boeing 727-200F flying westbound cargo plane), where 185 people are killed.
Charles Martin Smith plays Henry Drake, an air traffic controller who insists his radar system malfunctioned when the planes were being cleared for landing. When the rest of air traffic control dismiss Drake and blame the incident on human error, Dantley must discover the truth about the crash: Was Drake — a high-strung individual who already didn't get along with his co-workers — simply incompetent at his job or did Drake's co-workers and superiors know about and/or had been previously been warned about the aging radar system showing signs of seriously malfunctioning and crashing at critical times (and thus liable to lead to deadly situations such as the one that happened), but instead of taking action ignored the warnings and initiated a cover-up?.

Output: What were the two flights that an NTSB officer was sent to O'Hare Airport to investigate a collision between?


Input: Consider Input: Passage: In 1916, childhood best friends, Bob Wilson and Fred von Bergen, are test pilots working for an American company that builds bombers for the European allies. Since he is German-born and faces prejudice against his heritage, Fred loses his job and, unable to find other employment, decides to return to Germany to fight for his homeland. Although he has no special attachment to the German cause, Bob quits the aviation company and joins his friend in Germany. 
On their way to a German airfield, Red Cross nurse Alida Hoffman accidentally runs Bob and Fred off the road, Both men are immediately drawn to Alida, especially Bob although Fred is more shy. After Bob's first unsuccessful mission, Captain Wolters, the squadron's tyrannical leader, expresses his doubt about his loyalty but, desperate for pilots, gives him another chance. 
As the United States is drawn into the war, instead of sending him into a crucial air battle, Wolters arrests Bob. Fred, heartbroken that Alida has chosen Bob, quarrels with his friend, calling him a coward. Later, however, Fred allows his friend to escape from a firing squad and flee to the Allied lines. 
To prove his allegiance, Bob leads British bombers to the German base, while Fred is told by Wolters that he must shoot down Bob to prove his loyalty. Neither man is capable of killing the other, and, in the end, Fred sacrifices his life for Bob. After the war, Bob returns to Germany to marry Alida. The newly married couple then returns to the United States, and pay their respects to Fred's mother.

Output: What is the first name of the man that is fired for being German-born?


Input: Consider Input: Passage: Ash Mattley, a doctor in a small village deep in the jungles of Borneo, is approached by another scientist, Carl Wessinger regarding his studies of an enzyme found in a rare beetle. With the aid of Mattley and a group of natives, Wessinger secures several of the beetles, but then betrays his team and leaves them behind in a cave. Later, Wessinger uncovers a fossil in the jungle, but the natives in his new team fall in fear and worship before the deceased creature, which they call "Balakai."
Two years later, Mattley's clinic is beset by a series of gruesome murders in the jungle. The natives attribute the killings to Balakai, who is an ancient myth in the area. Mattley is enlisted by Claire Sommers, a CIA agent, to find Wessinger. The government had been monitoring Wessinger's activities in the jungle after he began working for them, but the doctor had recently fallen off radar, and Sommers reveals she has been sent to track him down. Together with Matzu, a boy whose sister was one of the victims, they set out into the jungle. Mattley does not initially believe that Balakai is real, but Sommers eventually tells him that the CIA was funding Wessinger's research into the fossil, leading him to change his mind.


Output: What is the first name of the doctor who fell off the radar?
