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: Charlemagne planned to continue the Frankish tradition of dividing his kingdom between all his heirs, but was unable to do so as only one son, Louis the Pious (r. 814–840), was still alive by 813. Just before Charlemagne died in 814, he crowned Louis as his successor. Louis's reign of 26 years was marked by numerous divisions of the empire among his sons and, after 829, civil wars between various alliances of father and sons over the control of various parts of the empire. Eventually, Louis recognised his eldest son Lothair I (d. 855) as emperor and gave him Italy. Louis divided the rest of the empire between Lothair and Charles the Bald (d. 877), his youngest son. Lothair took East Francia, comprising both banks of the Rhine and eastwards, leaving Charles West Francia with the empire to the west of the Rhineland and the Alps. Louis the German (d. 876), the middle child, who had been rebellious to the last, was allowed to keep Bavaria under the suzerainty of his elder brother. The division was disputed. Pepin II of Aquitaine (d. after 864), the emperor's grandson, rebelled in a contest for Aquitaine, while Louis the German tried to annex all of East Francia. Louis the Pious died in 840, with the empire still in chaos.A three-year civil war followed his death. By the Treaty of Verdun (843), a kingdom between the Rhine and Rhone rivers was created for Lothair to go with his lands in Italy, and his imperial title was recognised. Louis the German was in control of Bavaria and the eastern lands in modern-day Germany. Charles the Bald received the western Frankish lands, comprising most of modern-day France. Charlemagne's grandsons and great-grandsons divided their kingdoms between their descendants, eventually causing all internal cohesion to be lost. In 987 the Carolingian dynasty was replaced in the western lands, with the crowning of Hugh Capet (r. 987–996) as king. In the eastern lands the dynasty had died out earlier, in 911, with the death of Louis the Child, and the selection of the unrelated Conrad I (r. 911–918) as king.The breakup of the Carolingian Empire was accompanied by invasions, migrations, and raids by external foes. The Atlantic and northern shores were harassed by the Vikings, who also raided the British Isles and settled there as well as in Iceland. In 911, the Viking chieftain Rollo (d. c. 931) received permission from the Frankish King Charles the Simple (r. 898–922) to settle in what became Normandy. The eastern parts of the Frankish kingdoms, especially Germany and Italy, were under continual Magyar assault until the invader's defeat at the Battle of Lechfeld in 955. The breakup of the Abbasid dynasty meant that the Islamic world fragmented into smaller political states, some of which began expanding into Italy and Sicily, as well as over the Pyrenees into the southern parts of the Frankish kingdoms.
Example Output: What is the name of the person whose entire family except one son was deceased by 813?

Example Input: Passage: Most of Glicken's published work centers around the 1980 eruption of Mount St. Helens. He also coauthored works with other volcanologists that focused on debris avalanches. Colleague Jon Major writes that "The full scope of Harry's work ... has never been published."

Example Input: Passage: Sir Osbert Lancaster, CBE (4 August 1908 – 27 July 1986) was an English cartoonist, architectural historian, stage designer and author. He was known for his cartoons in the British press, and for his lifelong work to inform the general public about good buildings and architectural heritage. 
The only child of a prosperous family, Lancaster was educated at Charterhouse School and Lincoln College, Oxford, at both of which he was an undistinguished scholar. From an early age he was determined to be a professional artist and designer, and studied at leading art colleges in Oxford and London. While working as a contributor to The Architectural Review in the mid-1930s, Lancaster published the first of a series of books on architecture, aiming to simultaneously amuse the general reader and demystify the subject. Several of the terms he coined as labels for architectural styles have gained common usage, including "Pont Street Dutch" and "Stockbrokers' Tudor", and his books have continued to be regarded as important works of reference on the subject.
In 1938 Lancaster was invited to contribute topical cartoons to The Daily Express. He introduced the single column-width cartoon popular in the French press but not until then seen in British papers. Between 1939 and his retirement in 1981 he drew about 10,000 of these "pocket cartoons", which made him a nationally known figure. He developed a cast of regular characters, led by his best-known creation, Maudie Littlehampton, through whom he expressed his views on the fashions, fads and political events of the day.
From his youth, Lancaster wanted to design for the theatre, and in 1951 he was commissioned to create costumes and scenery for a new ballet, Pineapple Poll. Between then and the early 1970s he designed new productions for the Royal Ballet, Glyndebourne, D'Oyly Carte, the Old Vic and the West End. His productivity declined in his later years, when his health began to fail. He died at his London home in Chelsea, aged 77. His diverse career, honoured by a  knighthood in 1975, was celebrated by an exhibition at the Wallace Collection marking the centenary of his birth and titled Cartoons and Coronets: The Genius of Osbert Lancaster.
Example Output:
What is the last name of the person who was known for his cartoons in the British press?
