TASK DEFINITION: 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.
PROBLEM: Passage: Most park visitors sightsee using the scenic drive, which provides access to 13 viewpoints over the amphitheaters. Bryce Canyon has eight marked and maintained hiking trails that can be hiked in less than a day (round trip time, trailhead): Mossy Cave (one hour, State Route 12 northwest of Tropic), Rim Trail (5–6 hours, anywhere on rim), Bristlecone Loop (one hour, Rainbow Point), and Queens Garden (1–2 hours, Sunrise Point) are easy to moderate hikes. Navajo Loop (1–2 hours, Sunset Point) and Tower Bridge (2–3 hours, north of Sunrise Point) are moderate hikes. Fairyland Loop (4–5 hours, Fairyland Point) and Peekaboo Loop (3–4 hours, Bryce Point) are strenuous hikes. Several of these trails intersect, allowing hikers to combine routes for more challenging hikes.
The park also has two trails designated for overnight hiking: the 9-mile (14 km) Riggs Spring Loop Trail and the 23-mile (37 km) Under-the-Rim Trail. Both require a backcountry camping permit. In total there are 50 miles (80 km) of trails in the park.
More than 10 miles (16 km) of marked but ungroomed skiing trails are available off of Fairyland, Paria, and Rim trails in the park. Twenty miles (32 km) of connecting groomed ski trails are in nearby Dixie National Forest and Ruby's Inn.
The air in the area is so clear that on most days from Yovimpa and Rainbow points, Navajo Mountain and the Kaibab Plateau can be seen 90 miles (140 km) away in Arizona. On extremely clear days, the Black Mesas of eastern Arizona and western New Mexico can be seen some 160 miles (260 km) away.The park also has a 7.4 magnitude night sky, making it one of the darkest in North America. Stargazers can, therefore, see 7,500 stars with the naked eye, while in most places fewer than 2,000 can be seen due to light pollution, and in many large cities only a few dozen can be seen. Park rangers host public stargazing events and evening programs on astronomy, nocturnal animals, and night sky protection. The Bryce Canyon Astronomy Festival, typically held in June, attracts thousands of visitors. In honor of this astronomy festival, Asteroid 49272 was named after the national park.There are two campgrounds in the park, North Campground and Sunset Campground. Loop A in North Campground is open year-round. Additional loops and Sunset Campground are open from late spring to early autumn. The 114-room Bryce Canyon Lodge is another way to stay overnight in the park.

SOLUTION: Which hiking trail in Bryce Canyon has the longest estimated hiking time?

PROBLEM: 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.

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

PROBLEM: Passage: Lucy finds that her adoptive father, a museum curator, has been attacked by Silas. Before dying, he gives clues which lead her to a "Golden Ticket" in a vending machine candy bar. During "comedic" situations, Golden Tickets are found by other orphans, which include Edward, a disillusioned monk trainee; Susan, a displaced adopted girl; and Peter, a mutant at Mutant Academy who is often teased for his chicken-like wings. All four meet up at Willy's Chocolate Factory. Willy reveals his plot to use them all as a special ingredient in his treats.
In an effort to hide from the maniacal Willy, Lucy finds a wardrobe. On the other side, in the middle of a wintry forest, she finds Mr. Tumnus, who welcomes Lucy to Gnarnia and warns her of danger. The others follow Lucy to Gnarnia, and Edward meets the White Bitch. She convinces him to trap the other orphans in order to become the king of Gnarnia in her White Castle. All four go to Tumnus' house, where they discover that they are all related to one another in a copy of the famous painting The Last Supper, and that the White Bitch killed their parents. They ally themselves with Harry Beaver, Tumnus' life partner, to defeat the White Bitch.
