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: An inventory of medium and large mammals in the park confirmed the presence of 30 species in Saguaro National Park between 1999 and 2008. Of these, 21 were found in the Tucson Mountain District and 29 in the Rincon Mountain District. A partial list of the park's mammals includes cougars, coyotes, bobcats, white-tailed deer, mule deer, javelinas, gray foxes, black-tailed jackrabbits, desert cottontails, ring-tailed cats, white-nosed coatis, ground squirrels, and packrats. One endangered mammal, the lesser long-nosed bat, lives part of the year in the park and part of the year in Mexico.The wide range of habitats in the park supports a diverse population of birds including some, such as the vermilion flycatcher and the whiskered screech owl, uncommon elsewhere in the United States. Among the park's 107 bird species are great horned owls, cactus wrens, ravens, kestrels, turkey vultures, roadrunners, woodpeckers, hawks, quails, and hummingbirds, and one threatened species, the Mexican spotted owl.The park's 36 reptile species include desert tortoises, diamondback rattlesnakes (one of the more commonly seen snakes), coral snakes, Gila monsters, short-horned lizards, spiny lizards, and zebra-tailed lizards. Despite the aridity, three amphibian species inhabit the park: the canyon tree frog, the lowland leopard frog, and Couch's spadefoot, which lives in underground burrows, emerging to breed during summer rains. Forest fires, which create erosion-prone burned areas, have destroyed many of the leopard frog's breeding pools, which fill with sediment. The Arizona Game and Fish Department lists the lowland leopard frog as a species of special concern.Urban sprawl, air and water pollution, noise, light pollution, and a range of habitat restricted by human infrastructure put stress on the park's mammals and other animals, but the most serious immediate threat to them is roadkill. About 50,000 vertebrates a year die on the park's roads when they are hit by a vehicle. The Rincon Mountain District has few roads, but Picture Rocks Road, an east–west commuter highway crossing the Tucson Mountain District, is highly dangerous to wildlife. Attempts in 2002 to convert it to a hiking trail failed after the proposal met with stiff public resistance.
[EX A]: What was attempted to be converted into a hiking trail?

[EX Q]: Passage: Possibly because of its size, The Sirens and Ulysses failed to sell at the 1837 Summer Exhibition. In October 1837 wealthy Manchester cotton merchant Daniel Grant, an admirer of Etty who had already commissioned Venus and her Doves from him, met Etty at Heaton Park races and offered to buy The Sirens and Ulysses and Etty's smaller Samson Betrayed by Delilah unseen for a total of £200. Etty was hoping for £400 for the two paintings, but on being told by Grant that his firm had lost £100,000 that year offered a price of £300 for the pair. Grant counter-offered £250 (about £22,000 in today's terms), which Etty refused. On leaving at the end of the evening, Grant suddenly said, "Will you take the money?", startling Etty, who in his surprise agreed. Grant died shortly afterwards, leaving the painting to his brother William, who in turn gave it to the Royal Manchester Institution in 1839.Etty considered the painting to be his best work, insisting that it form the centrepiece of his 1849 Royal Society of Arts solo exhibition. The Royal Manchester Institution was concerned that the painting would be damaged if moved, refusing to allow it to be used in the exhibition until Etty, and a number of influential friends, visited Manchester to beg them to release it. Etty died later that year, and his work enjoyed a brief boom in popularity. Interest in him declined over time, and by the end of the 19th century the cost of all his paintings had fallen below their original prices. As it was rarely exhibited, The Sirens and Ulysses had little influence on later artists, although it is credited as an influence on Frederic Leighton's 1858 The Fisherman and the Syren.
Ulysses and the Sirens is one of those great efforts of my Art achieved in the vigour of my life, I can never make again.
[EX A]: What were the names of what Etty was hoping to get £400 for?

While at a nightclub, Dixie does a musical number and catches the eye of Frank Buelow, a Hollywood director. Buelow persuades Dixie to go to Hollywood, where he will have a part waiting for her in his upcoming films.
Dixie takes the next train to California. When she arrives, she is disappointed to find that Buelow has been fired from the studio and that there is no part for her. Dixie meets Donny Harris, a former star who is now out of work because she is considered "as old as the hills" at the age of 32. Soon after, Dixie discovers that Jimmie Doyle is now in Hollywood because one of the movie studios had just bought the film rights to his musical play.
