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.

Question: Passage: Twist's mother dies in childbirth in the middle of nowhere. Fearing blame, the locals bury her in an unmarked grave and drop the baby at a rural orphanage, where he is named Twist.
Growing up in the dusty wastes of the Swartland, sold from orphanage into child labour on the farms, and later to a rural undertaker, Twist finally takes his fate into his own hands and escapes to Cape Town. Wide eyed at the wonders of the city, he falls in with Fagin - an ancient Ethiopian, Rastafarian, who runs a network of child thieves. His new friend Dodger teaches him the tricks of the trade, but the inexperienced Twist is caught trying to steal from Ebrahim Bassedien.
Although neither understand it, there is a strange affinity between this old man - who has lost his daughter - and the young boy who never knew his mother. Bassedien takes the little stroller in and for a moment it seems that the trauma is over - as the little boy encounters love for the first time in his short and brutal life.
Enter Monks - the only person who knows Twist's true identity. He is paying Fagin to keep the little boy marginalised. If he ends up in jail or dead on the street, so much the better, for Monks stands to lose his inheritance if anybody ever discovers that Twist is Bassedien's grandson.
The brutal gangster Bill Sykes, and his prostitute girlfriend, Nancy, steal Twist back for Fagin, and the struggle for a little boy's soul begins in earnest.

Answer: What person never knew his mother?


Question: 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.

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


Question: Passage: King Arthur was a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas. Arthur's name also occurs in early poetic sources such as Y Gododdin.Arthur is a central figure in the legends making up the Matter of Britain. The legendary Arthur developed as a figure of international interest largely through the popularity of Geoffrey of Monmouth's fanciful and imaginative 12th-century Historia Regum Britanniae (History of the Kings of Britain). In some Welsh and Breton tales and poems that date from before this work, Arthur appears either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, sometimes associated with the Welsh otherworld Annwn. How much of Geoffrey's Historia (completed in 1138) was adapted from such earlier sources, rather than invented by Geoffrey himself, is unknown.
Although the themes, events and characters of the Arthurian legend varied widely from text to text, and there is no one canonical version, Geoffrey's version of events often served as the starting point for later stories. Geoffrey depicted Arthur as a king of Britain who defeated the Saxons and established a vast empire. Many elements and incidents that are now an integral part of the Arthurian story appear in Geoffrey's Historia, including Arthur's father Uther Pendragon, the magician Merlin, Arthur's wife Guinevere, the sword Excalibur, Arthur's conception at Tintagel, his final battle against Mordred at Camlann, and final rest in Avalon. The 12th-century French writer Chrétien de Troyes, who added Lancelot and the Holy Grail to the story, began the genre of Arthurian romance that became a significant strand of medieval literature. In these French stories, the narrative focus often shifts from King Arthur himself to other characters, such as various Knights of the Round Table.
Arthurian literature thrived during the Middle Ages but waned in the centuries that followed until it experienced a major resurgence in the 19th century. In the 21st century, the legend lives on, not only in literature but also in adaptations for theatre, film, television, comics and other media.

Answer:
What is the full name of the sword of the legendary British medieval leader?
