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: In 1690, Sir John Brownlow was granted permission to enclose an area of 1,000 acres (4 km²) to transform into a park, with a grant to keep deer. There is evidence to suggest that some of this area had been a park since at least 1580. The park was laid out with avenues, including the still surviving Eastern Avenue which led east from the house. Brownlow also had a large pond or lake dug and planted 21,400 ash trees, 9,500 oak trees, and 614 fruit trees. It is thought that William Winde may have advised on the layout of the gardens. Closer to the house were a series of more formal gardens, including canal ponds bordered by plantations containing symmetrical walks resembling the "rond-points" (circular clearings in a garden from which straight paths radiate) introduced by the landscape gardener André Le Nôtre. By the end of the eighteenth century, these formal parterres had been removed and the canal ponds filled in.Sir John Brownlow was succeeded at Belton by his brother, who was content to permit Brownlow's widow, Alice, to remain in occupation. She spent the remainder of her life at Belton arranging advantageous marriages for her five daughters. On her death in 1721, the house passed to her husband's nephew (and her son-in-law) Sir John Brownlow III (later Viscount Tyrconnel). Tyrconnel, a dilettante of no great intellect, was responsible for many of the architectural features which survive in the park and garden. Between 1742 and 1751, a series of follies, including a Gothic ruin, a cascade, and a prospect or belvedere known as the Belmount Tower, were constructed for him. When built the tower had two small wings flanking each side, since removed.John Cust, 1st Earl Brownlow, owner of Belton House from 1807–1853, commissioned the architect Anthony Salvin to undertake improvements to the Estate in 1838. Salvin's additions included a public house, estate cottages, a hermitage and the boathouse.

Ex Output:
What was the last name of the person who had a large pond or lake dug?

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.

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.

Ex Output:

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