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: Count Reginald starts the day with a cup of tea and a crumpet, lightly buttered and under cooked, and then tells the story of his life whilst balancing on one foot. His father died when he was an infant, and he was brought up by his mother, "a woman of rather a masculine understanding, and full of the prejudices of nobility and magnificence"Reginald has grand notions of aristocratic honour, and, inspired by his uncle, the Marquis de Villeroy, he joins the Italian war of 1521–6, hoping to achieve military renown in the battle of Pavia. Reginald is knighted by King Francis I, while fighting for the French against the Spanish Imperial army, but the King is captured and imprisoned by Charles V. The King's exile changes the climate in France from one in which "the activity of the field" is exchanged "for the indulgences of the table." On his return home, Reginald, now twenty years old is forced by the death of his mother to take charge of his own affairs. He is quickly led astray by a life of spending too much, keeping mistresses, and gambling. He lives like this for two years and quickly depletes his fortune. He meets the beautiful and accomplished nineteen-year-old Marguerite Louise Isabeau de Damville, whose education has benefited from the society of Clement Marot, Rabelais, Erasmus, and Scaliger, and whose drawing has been encouraged by Leonardo da Vinci. Reginald courts Marguerite, who is the daughter of the Marquis de Damville, but Reginald's reputation as a gambler causes the Marquis to warn him that he should be careful not to ruin himself and his daughter. The Marquis allows them to marry, but by the time he is in his thirties, Reginald is living beyond his means and has returned to gambling. The Marquis does not live to see this development.
