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: The first years of the 14th century were marked by famines, culminating in the Great Famine of 131517. The causes of the Great Famine included the slow transition from the Medieval Warm Period to the Little Ice Age, which left the population vulnerable when bad weather caused crop failures. The years 131314 and 131721 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate changewhich resulted in a declining average annual temperature for Europe during the 14th centurywas accompanied by an economic downturn.
These troubles were followed in 1347 by the Black Death, a pandemic that spread throughout Europe during the following three years. The death toll was probably about 35 million people in Europe, about one-third of the population. Towns were especially hard-hit because of their crowded conditions. Large areas of land were left sparsely inhabited, and in some places fields were left unworked. Wages rose as landlords sought to entice the reduced number of available workers to their fields. Further problems were lower rents and lower demand for food, both of which cut into agricultural income. Urban workers also felt that they had a right to greater earnings, and popular uprisings broke out across Europe. Among the uprisings were the jacquerie in France, the Peasants' Revolt in England, and revolts in the cities of Florence in Italy and Ghent and Bruges in Flanders. The trauma of the plague led to an increased piety throughout Europe, manifested by the foundation of new charities, the self-mortification of the flagellants, and the scapegoating of Jews. Conditions were further unsettled by the return of the plague throughout the rest of the 14th century; it continued to strike Europe periodically during the rest of the Middle Ages.

Ex Output:
In terms of percentage how many people died from the Black Death?

Passage: Set in a future 1970, the United States is considering building bases on the Moon. Colonel Briteis, Major Bill Moore, and Doctor Wernher are sent to orbit the Moon to survey landing sites for future lunar missions. However, Dr. Wernher is an impostor whose mission is to destroy the US's Earth-orbiting space station, which he plans to do by colliding the rocket with the station on the way back from the Moon.
While on the way out, however, Wernher inadvertently gives his identity away. In the ensuing struggle for the control of the rocket, Col. Briteis has to make an emergency landing on the Moon. With them all marooned, Dr. Wernher redeems himself by helping establish communications with Earth, although an accident results in his untimely death. In response to the unexpected turn of events, the US authorities decide to make the immobilized spaceship the core of a new moon base. To avoid a scandal, their commander, General Greene, cajoles Major Moore into proposing to Colonel Briteis (so as not to have an unmarried male and female astronaut alone in close quarters for weeks). Briteis accepts, but requests that Major Moore be promoted to Brigadier General after they are married so that he will outrank her. Compared to later science fiction movies and TV shows, where women are full-fledged professionals, this film portrays the main female protagonist, Col. Briteis, as a nice but incompetent female who is easily frightened and turns to Major Moore as soon as things become dangerous.

Ex Output:
Which of the people sent to orbit the moon is not who they claim to be?

Passage: Tony Rivers, a troubled teenager at Rockdale High, is known for losing his temper and overreacting. A campus fight between Tony and classmate Jimmy gets the attention of the local police, Det. Donovan in particular. Donovan breaks up the fight and advises Tony to talk with a "psychologist" that works at the local aircraft plant, Dr. Alfred Brandon, a practitioner of hypnotherapy.
Tony declines, but his girlfriend Arlene, as well as his widowed father, show concern about his violent behavior. Later, at a Halloween party at the "haunted house", an old house at which several of the teenagers hang out, Tony attacks his friend Vic after being surprised from behind. After seeing the shocked expressions on his friends's faces, he realizes he needs help and goes to see Dr. Brandon.
On Tony's first visit, however, Brandon makes it clear that he has his own agenda while the teenager lies on the psychiatrist's couch: Tony will be an excellent subject for his experiments with a scopolamine serum he has developed that regresses personalities to their primitive instincts. Brandon believes that the only future that mankind has is to "hurl him back to his primitive state." Although Brandon's assistant, Dr. Hugo Wagner, protests that the experiment might kill Tony, Brandon continues and within two sessions suggests to Tony that he was once a wild animal.

Ex Output:
