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.

[EX Q]: Passage: Immediately after Aaliyah's death, there was uncertainty over whether the music video for "Rock the Boat" would ever air. It made its world premiere on BET's Access Granted on October 9, 2001. She won two posthumous awards at the American Music Awards of 2002; Favorite Female R&B Artist and Favorite R&B/Soul Album for Aaliyah. Her second and final film, Queen of the Damned, was released in February 2002. Before its release, Aaliyah's brother, Rashad, re-dubbed some of her lines during post-production. It grossed US$15.2 million in its first weekend, ranking number one at the box office. On the first anniversary of Aaliyah's death, a candlelight vigil was held in Times Square; millions of fans observed a moment of silence; and throughout the United States, radio stations played her music in remembrance. In December 2002, a collection of previously unreleased material was released as Aaliyah's first posthumous album, I Care 4 U. A portion of the proceeds was donated to the Aaliyah Memorial Fund, a program that benefits the Revlon UCLA Women's Cancer Research Program and Harlem's Sloan Kettering Cancer Center. It debuted at number three on the Billboard 200, selling 280,000 copies in its first week. The album's lead single, "Miss You", peaked at number three on the Billboard Hot 100 and topped the Hot R&B/Hip-Hop Songs chart. In August of the following year, clothing retailer Christian Dior donated profits from sales in honor of Aaliyah.In 2005, Aaliyah's second compilation album, Ultimate Aaliyah was released in the UK by Blackground Records. Ultimate Aaliyah is a three disc set, which included a greatest hits audio CD and a DVD. Andy Kellman of AllMusic remarked "Ultimate Aaliyah adequately represents the shortened career of a tremendous talent who benefited from some of the best songwriting and production work by Timbaland, Missy Elliott, and R. Kelly." A documentary movie Aaliyah Live in Amsterdam was released in 2011, shortly before the tenth anniversary of Aaliyah's death. The documentary, by Pogus Caesar, contained previously unseen footage shot of her career beginnings in 1995 when she was appearing in the Netherlands.In March 2012, music producer Jeffrey "J-Dub" Walker announced on his Twitter account that a song "Steady Ground", which he produced for Aaliyah's third album, would be included in the forthcoming posthumous Aaliyah album. This second proposed posthumous album would feature this song using demo vocals, as Walker claims the originals were somehow lost by his sound engineer. Aaliyah's brother Rashad later refuted Walker's claim, claiming that "no official album [is] being released and supported by the Haughton family.".
[EX A]: "Miss You" was the lead single on which album?

[EX Q]: 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.
[EX A]: Which hiking trail in Bryce Canyon has the longest estimated hiking time?

[EX Q]: Passage: Little documentary evidence of the games remains; contemporary and near-contemporary writings mostly record the major details and concentrate on the opening days. The poet Martial gives the most complete and only truly contemporary account in the form of his De Spectaculis ("On the Spectacles"), a somewhat sycophantic series of epigrams detailing the individual events of the games as an illustration of Titus' power and benevolence. Much of the work is concerned with praising Titus, and there have been difficulties with authenticating, dating and translating various portions, but Martial does give details of events not covered by other sources and the only known surviving complete record of a gladiatorial combat in the arena.The historian Suetonius was born in about AD 70, and started writing around AD 100. He was a child at the time of the games, but it is possible that he was born and raised in Rome, so he may have witnessed the inaugural games first-hand. His De Vita Caesarum (Lives of the Caesars, known also as The Twelve Caesars or Lives of the Twelve Caesars) probably completed around AD 117 to 127, includes some detail on the opening days of the games. Later in his history of Titus he reveals further information about the games. Suetonius' histories of the early Caesars have been criticised for being based on rumour and gossip rather than accurate historical sources, and he often reports from sources which contradict each other without attempting to analyse their quality or accuracy. However, he is generally regarded as a thorough scholar and has been praised for his balanced treatment of his subjects.The only other major source of information on the games is Cassius Dio who lived in the latter second and early third centuries. His History of Rome spans 80 books written in 22 years, but much of which are only fragments. He is noted for his attention to detail in administrative affairs, but for major events his writing can be merely impressionistic, with a greater emphasis put on his interpretation of the events' significance within the wider historical context rather than reporting details. His sources are varied: he relies on many of the major commentators but also seems to have paid close attention to public records. His account of the Titus games is not sourced.
[EX A]:
What is the full name of the person noted for his attention to detail in administrative affairs?
