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.

Input: Consider Input: Passage: With MacCallum's year of financial support over, Thomson's financial future became uncertain. He briefly looked into applying for a position as a park ranger, but balked after seeing that it could take months for the application to go through. Instead, he considered working in an engraving shop over the winter. He made little effort to sell his paintings, preferring to give them away, though he brought in some money from the paintings he sold. In mid-November, he donated In Algonquin Park to an exhibition organized to raise money for the Canadian Patriotic Fund. It was sold to Marion Long for $50 (equivalent to CAD$1,100 in 2018).In the spring of 1915, Thomson returned to Algonquin Park earlier than he had in any previous year and had already painted twenty-eight sketches by April 22. From April through July, he spent much of his time fishing, assisting groups on several different lakes, and sketching when he had time. In July, he was invited to send paintings to the Nova Scotia Provincial Exhibition in September. Because he was in Algonquin Park, his friends selected three works to send—two unidentified works from 1914 and the sketch Canadian Wildflowers. From the end of September to mid-October, he spent his time at Mowat, a village on the north end of Canoe Lake. By November, he was at Round Lake with Tom Wattie and Dr. Robert McComb. In late November, he returned to Toronto and moved into a shack behind the Studio Building that Harris and MacCallum fixed up for him, renting it for $1 a month.In 1915, MacCallum commissioned MacDonald, Lismer and Thomson to paint decorative panels for his cottage on Go-Home Bay. In October of that year, MacDonald went up to take dimensions. Thomson produced four panels which were probably meant to go over the windows. In April 1916, when MacDonald and Lismer went to install them, they found that MacDonald's measurements were incorrect and the panels did not fit.

Output: What is the name of the person who made little effort in selling his paintings?


Input: Consider Input: Passage: Erschallet, ihr Lieder is the third of the Weimar cantatas. It was the first composed for a feast day, Pentecost Sunday (Whit Sunday), Pentecost being a high holiday along with Christmas and Easter. The prescribed readings for the feast day are taken from the Acts of the Apostles, on the Holy Spirit (Acts 2:1–13), and from the Gospel of John, in which Jesus announces the Spirit who will teach, in his Farewell discourse (John 14:23–31). As in many Bach cantatas, the libretto is compiled from Bible text, contemporary poetry and chorale. The poetry is attributed to Salomon Franck, although the verses are not included in his printed editions. Several of Bach's early stylistic mannerisms appear here, such as a biblical quotation in a recitative second movement rather than in a first choral movement, arias following each other without a recitative in between, and dialogue in a duet.Franck's text shows elements of early Pietism: the expression of extreme feelings, for example "O seligste Zeiten!" (O most blessed times) in the opening chorus, and a "mystical demeanour", for example in the duet of the Soul and the Spirit united. In the middle section of the first movement, Franck paraphrases the Gospel text, which says in verse 23 that God wants to dwell with man, to "Gott will sich die Seelen zu Tempeln bereiten" (God Himself shall prepare our souls for His  temple, more literally: "God wants to prepare [our] souls to become his temples"). The words for the recitative are the quotation of verse 23 from the Gospel of John, "Wer mich liebet, der wird mein Wort halten" (Whoever loves Me will keep My Word, and My Father will love him, and We will come to him and make Our dwelling with him). Movement 3 addresses the Trinity and movement 4 the Spirit that was present at the Creation. Movement 5 is a duet of the Soul and the Spirit, underlined by an instrumental quote from Martin Luther's Pentecost hymn "Komm, Heiliger Geist, Herre Gott", which is based on the Latin hymn "Veni Sancte Spiritus, reple tuorum corda fidelium". Movement 6 is a chorale, verse four of Philipp Nicolai's hymn "Wie schön leuchtet der Morgenstern". Nicolai's "Geistlich Brautlied" (Spiritual bridal song) continues the theme of unity between Soul and Spirit.

Output: What books of the Bible are the prescribed readings for the feast day taken from?


Input: Consider Input: 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.


Output: What were the names of the two rivers that had a dramatic drop in elevation?
