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

Passage: In late July 1983, Metallica embarked on the two-month Kill 'Em All for One tour with British co-headliners Raven. The tour name melded the titles of the albums the two bands were promoting: Metallica's Kill 'Em All and Raven's All for One, both released on Megaforce. The two groups met in Zazula's home two days before the tour began, and traveled in the same vehicle throughout the tour with five roadies and sound engineer Whitaker. The tour was set to conclude with three shows in San Francisco, thus Hetfield painted "No Life 'til Frisco" on the Winnebago tour bus. The tour had a few poorly attended gigs, such as a performance at the Cheers club in Babylon, New York, attended by some 50 people. After the conclusion of Kill 'Em All for One in early September, Metallica returned to El Cerrito to work on new material. Seven weeks after the tour ended, Metallica booked a number of performances at Bay Area clubs, the first a Halloween gig at the Keystone in Palo Alto. At the Country Club in Reseda, the group debuted "Fight Fire with Fire" and "Creeping Death", along with an early version of "The Call of Ktulu", then titled "When Hell Freezes Over". Three days later, at a gig at The Stone in San Francisco, Metallica premiered "Ride the Lightning", the title track from the upcoming album. In December, Metallica went on a short tour in the Midwest and eastern United States with a three-man road crew: Whitaker, guitar technician John Marshall, and drum technician Dave Marrs. The concert of January 14, 1984 in Boston was canceled because the band's equipment was stolen the night before.In February, Metallica embarked on its first European trek with Twisted Sister, supporting Venom's Seven Dates of Hell tour. The tour was sponsored by Metallica's UK distributor, Music for Nations, who released the "Jump in the Fire" EP for that occasion. The first show was at the Volkshaus in Zurich on February 3. At the Aardschok Festival in Zwolle on February 11, Metallica played in front of 7,000 people, its largest audience at the time. The tour stretched through countries such as Italy, Germany, France, and Belgium, culminating in two sold-out shows at the Marquee Club in London. After concluding the Seven Dates Of Hell tour, Metallica headed to Sweet Silence Studios in Copenhagen to record its sophomore album Ride the Lightning. By the end of the tour, Kill 'Em All had sold 60,000 copies worldwide and Metallica began to gain international recognition.
On June 8, 2013, at the Orion Festival, billed as the fictional band Dehaan, Metallica played the album in its entirety for the first time ever to mark the 30 year anniversary of the album.
What are the specific titles of the two separate albums by Metallica and Raven, respectively, that were melded together to form the name for their co-headlining tour?

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 1976–1989, 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.

What was the name of the person that used the name Spike WIlbury?
