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.

[EX Q]: Passage: Donald Duck is doing some camouflage painting on a cannon with yellow, green, and red stripes and black dots (based on the colors of the Flag of Lithuania with bullet holes in it). Sergeant Pete sees it and scolds Donald, explaining that it needs to painted so it can't be seen.  Pete then demands that Donald re-paint the cannon to make it "hard to see".  Obliging to the sergeant's orders, Donald walks to the "Experimental Laboratory: Camouflage Corps", disregarding the 'keep out' sign, and walks in. He finds some "invisible paint", which he tests with his finger, and uses it to paint the cannon.
When Pete returns, he is shocked to find the cannon seemingly gone, believing it to be stolen.  But of course it isn't stolen, as the sergeant finds out the hard way by bonking his head on the underside of the cannon and discovering Donald inside.  Angered that Donald painted the cannon too invisible to see, Pete blows hard into one end of the barrel, sending Donald out the other end and into the bucket of invisible paint.  When Donald runs away, Pete finds out Donald has become invisible after seeing Donald's footprints on the ground.  Donald then swims across a lake, but the invisible paint doesn't come off.
Pete continues to chase Donald through a field of flowers, until he accidentally throws some of the flowers on Donald, revealing his outline.  Pete spots Donald and tries to catch him, but he gets away again.  However, this gives Pete an idea to find Donald.  When the General drives up, Pete's antics, including jumping around a tree while singing "Here We Go Round The Mulberry Bush" and throwing flowers, convinces the General that he is acting odd, especially after he asks the General "did you see a little guy that you can't see?"  The invisible Donald then puts a cactus down Pete's pants, making him scream in pain and jump around like a madman, making the General wonder what is going on with Pete.
[EX A]: Who hits his head on the cannon?

[EX Q]: 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.
[EX A]: What is the name of the person who made little effort in selling his paintings?

[EX Q]: Passage: Out of the four theaters included in plan H-1, of March 1930, the city only approved the construction of two; and thus, only these two theaters were constructed. Samuel "Roxy" Rothafel, a successful theater operator who was renowned for his dominance of the city's theater industry, joined the center's advisory board in 1930. He offered to build two theaters: a large, vaudeville "International Music Hall", on the northernmost block, with more than 6,200 seats; and the smaller, 3,500-seat "RKO Roxy" movie theater on the southernmost block. The idea for these theaters was inspired by Roxy's failed expansion of the 5,920-seat Roxy Theatre on 50th Street, one-and-a-half blocks away. Roxy also envisioned an elevated promenade between the two theaters, but this was never published in any of the official blueprints. Meanwhile, proposals for a Metropolitan Opera House on the site persisted. Official plans for a facility to the east of the RKO Roxy were filed in April 1932; the projected 4,042-seat opera facility would contain features such as a second-floor esplanade extending across 50th Street. However, the Met was unable to fund such a move, so the proposed new opera house was relegated to tentative status.In September 1931, a group of NBC managers and architects toured Europe to find performers and look at theater designs. However, the group did not find any significant architectural details that they could use in the Radio City theaters. In any case, Roxy's friend Peter B. Clark turned out to have much more innovative designs for the proposed theaters than the Europeans did. The Music Hall was designed by architect Edward Durell Stone and interior designer Donald Deskey in the Art Deco style. Eugene Schoen was selected to design the RKO Roxy.
