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.

Input: Consider Input: Passage: Michael Joseph Jackson (August 29, 1958 June 25, 2009) was an American singer, songwriter, and dancer. Dubbed the "King of Pop", he is widely regarded as one of the most significant cultural figures of the 20th century and one of the greatest entertainers of all time. He was also known for his unorthodox lifestyle, residing in a private amusement park he called Neverland Ranch, and often becoming the focus of tabloid scrutiny. Jackson's contributions to music, dance, and fashion, along with his publicized personal life, made him a global figure in popular culture for over four decades.
The eighth child of the Jackson family, Michael made his professional debut in 1964 with his elder brothers Jackie, Tito, Jermaine, and Marlon as a member of the Jackson 5. He began his solo career in 1971 while at Motown Records, and in the early 1980s, became a dominant figure in popular music. His music videos, including those for "Beat It", "Billie Jean", and "Thriller" from his 1982 album Thriller, are credited with breaking racial barriers and transforming the medium into an art form and promotional tool. Their popularity helped bring the television channel MTV to fame. Bad (1987) was the first album to produce five US Billboard Hot 100 number-one singles. He continued to innovate throughout the 1990s with videos such as "Black or White" and "Scream", and forged a reputation as a touring artist. Through stage and video performances, Jackson popularized complicated dance techniques such as the robot and the moonwalk, to which he gave the name. His sound and style have influenced artists of various genres.
Jackson is one of the best-selling music artists of all time, with estimated sales of over 350 million records worldwide; Thriller is the best-selling album of all time, with estimated sales of 66 million copies worldwide. His other albums, including Off the Wall (1979), Bad (1987), Dangerous (1991), and HIStory (1995), also rank among the world's best-selling. He won hundreds of awards (more than any other artist in the history of popular music), has been inducted into the Rock and Roll Hall of Fame twice, and is the only pop or rock artist to have been inducted into the Dance Hall of Fame. His other achievements include Guinness world records (including the Most Successful Entertainer of All Time), 15 Grammy Awards (including the Legend and Lifetime Achievement awards), 26 American Music Awards (more than any other artist), and 13 number-one US singles (more than any other male artist in the Hot 100 era). Jackson was the first artist to have a top ten single in the Billboard Hot 100 in five different decades. In 2016, his estate earned $825 million, the highest yearly amount for a celebrity ever recorded by Forbes.

Output: What is the first name of the person whose estate in 2016, earned $825 million, the highest yearly amount for a celebrity ever recorded by Forbes?

Input: Consider Input: 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 (56 hours, anywhere on rim), Bristlecone Loop (one hour, Rainbow Point), and Queens Garden (12 hours, Sunrise Point) are easy to moderate hikes. Navajo Loop (12 hours, Sunset Point) and Tower Bridge (23 hours, north of Sunrise Point) are moderate hikes. Fairyland Loop (45 hours, Fairyland Point) and Peekaboo Loop (34 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.

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

Input: Consider Input: Passage: In addition to developing the atomic bomb, the Manhattan Project was charged with gathering intelligence on the German nuclear energy project. It was believed that the Japanese nuclear weapons program was not far advanced because Japan had little access to uranium ore, but it was initially feared that Germany was very close to developing its own weapons. At the instigation of the Manhattan Project, a bombing and sabotage campaign was carried out against heavy water plants in German-occupied Norway. A small mission was created, jointly staffed by the Office of Naval Intelligence, OSRD, the Manhattan Project, and Army Intelligence (G-2), to investigate enemy scientific developments. It was not restricted to those involving nuclear weapons. The Chief of Army Intelligence, Major General George V. Strong, appointed Boris Pash to command the unit, which was codenamed "Alsos", a Greek word meaning "grove".
The Alsos Mission to Italy questioned staff of the physics laboratory at the University of Rome following the capture of the city in June 1944. Meanwhile, Pash formed a combined British and American Alsos mission in London under the command of Captain Horace K. Calvert to participate in Operation Overlord. Groves considered the risk that the Germans might attempt to disrupt the Normandy landings with radioactive poisons was sufficient to warn General Dwight D. Eisenhower and send an officer to brief his chief of staff, Lieutenant General Walter Bedell Smith. Under the codename Operation Peppermint, special equipment was prepared and Chemical Warfare Service teams were trained in its use.Following in the wake of the advancing Allied armies, Pash and Calvert interviewed Frederic Joliot-Curie about the activities of German scientists. They spoke to officials at Union Miniere du Haut Katanga about uranium shipments to Germany. They tracked down 68 tons of ore in Belgium and 30 tons in France. The interrogation of German prisoners indicated that uranium and thorium were being processed in Oranienburg, 20 miles north of Berlin, so Groves arranged for it to be bombed on 15 March 1945.An Alsos team went to Stassfurt in the Soviet Occupation Zone and retrieved 11 tons of ore from WIFO. In April 1945, Pash, in command of a composite force known as T-Force, conducted Operation Harborage, a sweep behind enemy lines of the cities of Hechingen, Bisingen, and Haigerloch that were the heart of the German nuclear effort. T-Force captured the nuclear laboratories, documents, equipment and supplies, including heavy water and 1.5 tons of metallic uranium.Alsos teams rounded up German scientists including Kurt Diebner, Otto Hahn, Walther Gerlach, Werner Heisenberg, and Carl Friedrich von Weizsacker, who were taken to England where they were interned at Farm Hall, a bugged house in Godmanchester. After the bombs were detonated in Japan, the Germans were forced to confront the fact that the Allies had done what they could not.
Output: What is the full name of the operation that was created to deal with the possibilty of radioactive poisons and train teams with special equipment?
