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: The original oil painting measures 380 by 580 centimetres (150 by 230 in). It depicts Arsenije leading tens of thousands of Serbs into exile, riding a horse and flanked by a Serb flag. In direct reference to the Bible, the image is reminiscent to that of Moses leading the chosen people out of Egypt. The irony, Judah notes, is that the Patriarch is leading his people away from their promised land. The Patriarch and four other figures dominate the composition, staggering unevenly across the canvas as opposed to moving in a straight line. "They punctuate the foreground," Filipovitch-Robinson writes, "directing the eye through the diagonals and curves of their bodies and gesture to the next line of figures behind them. Each subsequent line leads to the next." All age groups are represented in the painting, and Jovanovic pays special attention to their facial details. Thousands of figures on horseback and on foot appear in the background before eventually receding into the horizon. The left background shows Serbian warriors pointing their lances at the sky while the right background shows lumber wagons carrying families into exile. At the right foreground, an old man herds his sheep. To the right of the Patriarch, a mother and her infant son sit atop a horse carrying their belongings. The woman is the young wife of militia leader Jovan Monasterlija and the child his son. A mustachioed warrior walks before them with swords fastened to his belt and a rifle resting against his shoulder, "striding purposefully into the future". The warrior's right arm is smeared with blood and bound by a white sling.
What is the last name of the militia leader that the Patriarchin the painting is married to?

Passage: In 1924, Rix Nicholas, again travelling with Dorothy Richmond, set sail for France, intending to exhibit her works in Europe. She voyaged on the Ormonde, which was also carrying the Australian Olympic team. She befriended several of the team members and painted a portrait of one for an Olympic artists' competition.Arriving in Paris in June, eventually Rix Nicholas rented a studio in Montparnasse, which had previously belonged to French artist Rosa Bonheur. An exhibition at the "prestigious" Georges Petit Galerie in Paris in January 1925 was a great success. It led to important sales, including to the Musee du Luxembourg, making her the only Australian woman to have more than one work in its collection and, according to one report, one of only three Australian artists represented at all at that time, the others being Rupert Bunny and Arthur Streeton. The exhibition led also to a tour of her works to London and British regional galleries, the first time any Australian artist had archived such prominence; between 1926 and 1928, her works were shown in Hull, Sunderland, Tyne and Wear, Bootle, Blackpool, Northampton, Warrington, Folkestone, Leicester, Derby, Gateshead and Leek in Staffordshire.The work purchased by the Luxembourg in 1925 was In Australia, a portrait of Ned Wright, manager of the property at Delegate where she had stayed in the early 1920s. He is portrayed on horseback, a pipe clasped in his exposed and bright teeth, with a panoramic backdrop of an Australian pastoral landscape. His stance is casual, self-assured and heroic, consistent with the up-beat nationalism of Australia at the time.
What is the first name of the person who intended to exhibit her works in Europe?

Passage: Up until the mid-19th century, long stretches of the Colorado and Green rivers between Wyoming and Nevada remained largely unexplored due to their remote location and dangers of navigation. Because of the dramatic drop in elevation of the two rivers, there were rumors of huge waterfalls and violent rapids, and Native American tales strengthened their credibility. In 1869, one-armed Civil War veteran John Wesley Powell led an expedition from Green River Station in Wyoming, aiming to run the two rivers all the way down to St. Thomas, Nevada, near present-day Hoover Dam. Powell and nine men none of whom had prior whitewater experience set out in May. After braving the rapids of the Gates of Lodore, Cataract Canyon and other gorges along the Colorado, the party arrived at the mouth of the Little Colorado River, where Powell noted down arguably the most famous words ever written about the Grand Canyon of the Colorado:
We are now ready to start on our way down the Great Unknown. Our boats, tied to a common stake, are chafing each other, as they are tossed by the fretful river. They ride high and buoyant, for their loads are lighter than we could desire. We have but a month's rations remaining. The flour has been re-sifted through the mosquito net sieve; the spoiled bacon has been dried, and the worst of it boiled; the few pounds of dried apples have been spread in the sun, and re-shrunken to their normal bulk; the sugar has all melted, and gone on its way down the river; but we have a large sack of coffee. The lighting of the boats has this advantage: they will ride the waves better, and we shall have little to carry when we make a portage.
We are three-quarters of a mile in the depths of the earth, and the great river shrinks into insignificance, as it dashes its angry waves against the walls and cliffs, that rise to the world above; they are but puny ripples, and we but pigmies, running up and down the sands, or lost among the boulders.
We have an unknown distance yet to run; an unknown river yet to explore. What falls there are, we know not; what rocks beset the channel, we know not; what walls rise over the river, we know not; Ah, well! we may conjecture many things. The men talk as cheerfully as ever; jests are bandied about freely this morning; but to me the cheer is somber and the jests are ghastly.
What were the names of the two rivers that had a dramatic drop in elevation?
