instruction:
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: In 1988, Harrison formed the Traveling Wilburys with Jeff Lynne, Roy Orbison, Bob Dylan and Tom Petty. The band had gathered in Dylan's garage to record a song for a Harrison European single release. Harrison's record company decided the track, "Handle with Care", was too good for its original purpose as a B-side and asked for a full album. The LP, Traveling Wilburys Vol. 1, was released in October 1988 and recorded under pseudonyms as half-brothers, supposed sons of Charles Truscott Wilbury, Sr. It reached number 16 in the UK and number 3 in the US, where it was certified triple platinum. Harrison's pseudonym on the album was "Nelson Wilbury"; he used the name "Spike Wilbury" for their second album.In 1989, Harrison and Starr appeared in the music video for Petty's song "I Won't Back Down". In October that year, Harrison assembled and released Best of Dark Horse 19761989, a compilation of his later solo work. The album included three new songs, including "Cheer Down", which Harrison had recently contributed to the Lethal Weapon 2 film soundtrack.Following Orbison's death in December 1988, the Wilburys recorded as a four-piece. Their second album, issued in October 1990, was mischievously titled Traveling Wilburys Vol. 3. According to Lynne, "That was George's idea. He said, 'Let's confuse the buggers.'" It peaked at number 14 in the UK and number 11 in the US, where it was certified platinum. The Wilburys never performed live, and the group did not record together again following the release of their second album.In December 1991, Harrison joined Clapton for a tour of Japan. It was Harrison's first since 1974 and no others followed. On 6 April 1992, Harrison held a benefit concert for the Natural Law Party at the Royal Albert Hall, his first London performance since the Beatles' 1969 rooftop concert. In October 1992, he performed at a Bob Dylan tribute concert at Madison Square Garden in New York City, playing alongside Dylan, Clapton, McGuinn, Petty and Neil Young.
answer:
What was the name of the person that used the name Spike WIlbury?

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 eastwest 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: Yale grad Dan Brooks is expected to marry wealthy boss J.L. Higgins' (Charles Bickford) daughter Margaret and join the family box-making business. He is far more interested in racing a horse he owns, Broadway Bill.
Doing poorly at work, Dan and his groom Whitey leave town to enter Bill in the Imperial Derby, but first must find money for the entry fee. He and old pal Professor Pettigrew each try to con the other out of a few bucks, then end up singing the Yale school song to get out of a restaurant tab they cannot pay.
Maggie's younger sister Alice is secretly in love with Dan, so she offers him some money, pawning her belongings. Whitey is beaten up trying to win some in a craps game, and Broadway Bill is carted away because Dan does not pay his feed bill. Dan is jailed, too.
A rich man makes a bet on 100-to-1 shot Bill, leading to false rumors that the horse is a shoo-in. The odds drop fast, but gamblers and a crooked jockey try to make sure their own favorites win the race. Broadway Bill somehow manages to win, but collapses at the finish line and suffers a fatal heart attack.
A saddened Dan takes comfort in deciding to buy and race Broadway Bill II. His enthusiasm persuades Alice and even her dad to lend Dan a hand.
answer:
Who is Margaret's fathers name?
