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.

[Q]: Passage: As the 19th century progressed, the United States government's Indian removal policy pushed Native American tribes west of the Mississippi River. In 1830, the Indian Removal Act was signed into law, and though that act did not directly address the Potawatomi people of Indiana, it led to several additional treaties that resulted in their removal. In what came to be known as the Potawatomi Trail of Death, about 860 Potawatomi Indians who had refused to leave were forced to move from Indiana to Kansas. On September 14, 1838, the group camped near Williamsport, and on September 15 they camped in the southwestern part of the county before moving into Illinois. Before reaching their destination in Kansas, over 40 of them had died, many of them children; two children died and were buried at the second Warren County campsite.When the county was established, the Wabash River was vital to transportation and shipping. Zachariah Cicott traded up and down the river, and cities like Attica, Perrysville, Baltimore and Williamsport were founded near the river's banks and flourished because of it. In the 1840s, the Wabash and Erie Canal began to operate and provided even broader shipping opportunities, but the canal favored towns which were on the "right side" of the river; the canal was on the Fountain County side, and towns like Baltimore dwindled as a result. Some towns, such as Williamsport and Perrysville, managed to participate in canal traffic through the use of side-cuts that brought traffic from the canal across the river. When railroads were constructed starting in the 1850s, they in turn began to render the canals obsolete and allowed trade to reach towns that lacked water connections. The canal continued to be used through the early 1870s.
[A]: What decade did the canals that provided broader shipping opportunities start to decline due to railroads?

[Q]: Passage: Concepts of women's social rights and social status during the Tang era were notably liberal-minded for the period. However, this was largely reserved for urban women of elite status, as men and women in the rural countryside labored hard in their different set of tasks; with wives and daughters responsible for more domestic tasks of weaving textiles and rearing of silk worms, while men tended to farming in the fields. There were many women in the Tang era who gained access to religious authority by taking vows as Daoist priestesses. The head mistresses of the bordellos in the North Hamlet of the capital Chang'an acquired large amounts of wealth and power. Their high-class courtesans, who likely influenced the Japanese geishas, were well respected. These courtesans were known as great singers and poets, supervised banquets and feasts, knew the rules to all the drinking games, and were trained to have the utmost respectable table manners.Although they were renowned for their polite behavior, the courtesans were known to dominate the conversation amongst elite men, and were not afraid to openly castigate or criticize prominent male guests who talked too much or too loudly, boasted too much of their accomplishments, or had in some way ruined dinner for everyone by rude behavior (on one occasion a courtesan even beat up a drunken man who had insulted her). When singing to entertain guests, courtesans not only composed the lyrics to their own songs, but they popularized a new form of lyrical verse by singing lines written by various renowned and famous men in Chinese history.It was fashionable for women to be full-figured (or plump). Men enjoyed the presence of assertive, active women. The foreign horse-riding sport of polo from Persia became a wildly popular trend amongst the Chinese elite, and women often played the sport (as glazed earthenware figurines from the time period portray). The preferred hairstyle for women was to bunch their hair up like "an elaborate edifice above the forehead", while affluent ladies wore extravagant head ornaments, combs, pearl necklaces, face powders, and perfumes. A law was passed in 671 which attempted to force women to wear hats with veils again in order to promote decency, but these laws were ignored as some women started wearing caps and even no hats at all, as well as men's riding clothes and boots, and tight-sleeved bodices.There were some prominent court women after the era of Empress Wu, such as Yang Guifei (719756), who had Emperor Xuanzong appoint many of her relatives and cronies to important ministerial and martial positions.
[A]: What is the name of the sport that glazed earthenware figurines portrayed women playing?

[Q]: Passage: Princess Anne plans to run away with Freddie Granton, the commoner secretary of her father, King Eric VIII, once her domineering mother, Queen Martha, has left for a vacation in America. Anne is therefore aghast when the Marquis of Birten brings news that he has negotiated her political marriage to Prince William of Grec, a man she has never even met. Dismissing Anne's vehement protests, the Queen is delighted, a feeling not shared by Anne's loving but ineffectual father.
Meanwhile, the Premier and General Northrup warn that a revolution is brewing. He wishes to execute large numbers of political prisoners, but cannot without the King's signature. The Queen wholeheartedly approves of these stern measures. The King promises to attend to it, but after Northrup and the Queen leave, he orders his secretary to misplace the death warrants. Led by Laker, the rebels rise up after Northrup gets Parliament to grant him dictatorial powers. Anne seizes the opportunity to try to flee with Granton, with her father's approval. However, when she believes that the King is in real danger, she refuses to leave him.
Doctor Fellman, a moderate rebel leader, comes to see the King to demand his abdication, but agrees to stop the fighting in favor of negotiation. Then Northrup insists he is in charge now and laughs in derision when the King claims the people are stronger than Northrup's army and navy. Next to arrive is Prince William. Despite his admission that he dislikes Anne, he is prepared to do his duty and go through with the wedding. Then Fellman and Laker show up. The King surprises Northrup by dismissing him from his service and putting Fellman in charge, ordering him to set up general elections as soon as possible.
[A]:
What is the title of the person who is to be married to Prince William of Grec?
