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 1315–17. 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 1313–14 and 1317–21 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate change—which resulted in a declining average annual temperature for Europe during the 14th century—was 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.
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.
Which of the people sent to orbit the moon is not who they claim to be?

Passage: Russian company Sukhoi has developed a fifth-generation jet fighter, the Sukhoi Su-XX, nicknamed Sabretooth, flown by test pilot Alexei Kedrov, from a remote Russian airbase. Recently suspected of being a traitor due to his love affair with American ecologist Catherine Foley, Alexei is patriotic and is unaware that Catherine is not who she claims and is working with London-based arms dealer Dick Murdoch. A mystery man also appears to control the effort to steal the Sabretooth.
Murdoch and his new partner Aziza, want to steal the Russian jet and employing numerous mercenaries and clandestine agents, puts the entire flight test unit in jeopardy. Worried about his family, pilot Boris Korin helps Murdoch steal Sabretooth.  When Catherine is seen to be falling for Alexei, she is eliminated along with other assassinations and an audacious attack on a former Russian outpost.  Alexei and other pilots in his team have to contend with not only the Russian FSB, but also agents from the CIA and British special services. 
When Air Force One on the way to Moscow, is threatened, the McDonnell Douglas F-15 Eagle escorts try to shoot down Sabretooth but Alexei uses the extraordinary capability of his top-secret aircraft to outfly the American attack and bring his aircraft home safely. 
Murdoch, however, with help from the mystery man behind the efforts to steal Sabretooth, is still at large.
