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.

Question: 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.

Answer: What was attempted to be converted into a hiking trail?


Question: Passage: Agent Bart Langner finds Elsa Brinkmann, a would-be actress who looks and sounds just like  Lylah Clare, a flamboyant star who fell to her death in suspicious circumstances 20 years ago. He persuades arrogant director Lewis Zarkan, who had been married to Lylah, to see her. The two men then convince brash studio head Barney Sheean, who is equally struck, to back a picture with her as Lylah. 
Besides coping with the tyrannical Zarkan and easy access to alcohol and drugs, Elsa also has to contend with other hazards of Hollywood like malicious journalist Molly Luther and lesbian admirer Rossella. As filming continues, her identification with her rôle gets more intense. She also begins to fall in love with Zarkan, who is happy to sleep with her but his priority is to get his film finished. 
By the last day of shooting, her personality seems to have merged with that of the outrageous Lylah whose fatal fall, we learn, was prompted by the jealous Zarkan. To antagonise him, she first lets him find her in bed with the gardener. Then, as he directs her in a circus scene, she leaps to her death from the high-wire. The resulting publicity makes his film a huge success. Tragedy later comes when Zarkan himself is shot and killed by Rossella.
A final sequence (in this case, a TV commercial for dog food that interrupts the film itself) suggests that the world of Hollywood is literally one of dog eats dog.

Answer: Which person does Rossella admire?


Question: Passage: In the late 1830s, when much of the Old West was still Mexican territory, four people are traveling through the deserts, north of Texas and a three-day ride from Santa Fe.
One the Scalphunter, who says his trade is being a "buffaler" (buffalo hide trader). He is in search of gold. The others are a former ship Captain, also in search of the gold; the Woman from England, a former chambermaid who, in exchange for ship's passage to America, has signed an agreement to serve the Captain for five years as an indentured servant; and Mr. Rainbow, a former soldier who killed Indians.
The Captain sets out to find some of Montezuma's gold, risking danger from both the Native Indians and Mexican soldiers. The woman wants to get out of her contract with the Captain and go to New Orleans. She asks Mr. Rainbow to take her there, but he turns her down.
The Scalphunter wants half of the Captain's gold, and tags along with his men. Mr. Rainbow sets out across the desert through the Viaje de la Muerte, the Journey of Death.

Answer:
What does the nickname for the trade of the man searching for gold actually refer to?
