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.

Example Input: Passage: In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrović has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for a last sojourn on the surface. Crewmate Richard Harrington drives Petrović in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrović.
Captain Charles Brunel and crewmate Lauren Dalby plan to explore the pit to retrieve Petrović's body. Dalby remains at the pit but disappears before the team can return with equipment. Brunel authorizes Vincent Campbell to explore the pit and he finds a fungus-like life that grows in the fissure. Dalby and Petrović reappear at the main outpost, but the Martian bacteria has mutated them into fast, aggressive, zombie-like creatures with blackened skin and no trace of their original personalities. Harrington dies from a power drill attack by one of the zombies and later revives as one himself. The remaining crew hold off the zombies while Brunel and Campbell return. Brunel is also fatally injured and reanimates, which provides the crew with new insight into the symptoms: thirst, memory loss and aggression.
Example Output: What is the full name of the person who obtained the soil with the biological agent?

Example Input: Passage: Celia Crowson and her family go on holiday to the south coast of England in the summer of 1939. Soon afterwards the Second World War breaks out and Celia's father joins what was to become the Home Guard and her more confident sister Phyllis joins the Auxiliary Territorial Service. 
Fearing her father's disapproval if she moves away from home, Celia hesitates about joining up but eventually her call-up papers arrive. Hoping to join the WAAF or one of the other services, Celia instead gets posted to a factory making aircraft components, where she meets her co-workers, including her Welsh room-mate Gwen Price and the vain upper middle class Jennifer Knowles. Knowles dislikes the work they have to do at the factory, causing friction with their supervisor Charlie Forbes which eventually blossoms into a verbally combative romance.
A nearby RAF bomber station sends some of its men to a staff dance at the factory, during which Celia meets and falls in love with an equally shy young Scottish flight sergeant Fred Blake. Their relationship encounters a crisis when Fred refuses to tell Celia when he is sent out on his first mission, but soon afterwards they meet and make up, with Fred asking Celia to marry him. After the wedding they spend their honeymoon at the same south coast resort as the Crowsons went to in 1939, finding it much changed with minefields and barbed wire defending against the expected German invasion.
Example Output: What are the first names of the couple who meet and make up?

Example Input: Passage: Churchill's study, on the first floor, was his "workshop for over 40 years" and "the heart of Chartwell".
In the 1920s, as Chancellor of the Exchequer, he planned his budgets in the room; in the 1930s, in isolation, he composed his speeches that warned against the rise of Hitler and dictated the books and articles that paid the bills; in 1945, defeated, he retreated here to write his histories; and here, in final retirement, he passed much of his old age. Throughout the 1930s, the study was his base for the writing of many of his most successful books. His biography of his ancestor Marlborough and his The World Crisis were written there, and A History of the English-Speaking Peoples was begun and concluded there, although interrupted by the Second World War. He also wrote many of his pre-war speeches in the study, although the house was less used during the war itself. Tilden exposed the early roof beams by removing the late-Victorian ceiling and inserted a Tudor doorcase. From the beams hang three banners, Churchill's standards as Knight of the Garter and Lord Warden of the Cinque Ports and the Union Flag raised over Rome on the night of 5 June 1944, the first British flag to fly over a liberated capital. The latter was a gift from Lord Alexander of Tunis. The study also contains portraits of Churchill's parents, Lord Randolph Churchill and Lady Randolph Churchill, the latter by John Singer Sargent. The floor is covered with a Khorassan carpet, a 69th birthday gift to Churchill from the Shah of Iran at the Teheran Conference in 1943.Beyond the study are Churchill's bedroom and his ensuite bathroom, with sunken bath. At the time of the house's opening to the public in 1966, these rooms were not made accessible, at the request of Churchill's family but, shortly before her death in 2014, Churchill's daughter Mary gave permission for their opening, and the Trust plans to make them accessible by 2020.
Example Output:
What person did Churchill warn against?
