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: Willow has been cut and used on the Levels since mankind moved into the area. Fragments of willow basket were found near the Glastonbury Lake Village, and it was used in the construction of several Iron Age causeways. The willow was harvested using traditional methods of pollarding, where a tree would be cut back to the main stem. New shoots of willow, called "withies", would grow out of the trunk and these would be cut periodically for use.During the 1930s, over 9,000 acres (36 km2) of willow were being grown commercially on the Levels. Largely because of the replacement of baskets by plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 350 acres (1.4 km2) were grown commercially, near the villages of Burrowbridge, Westonzoyland, and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially. For weaving, the species Salix triandra (almond willow, black maul) is grown, while Salix viminalis (common osier) is ideal for handles, bases, and the structural members in furniture and hurdles. Historically willow was used to make salmon traps or "putchers". Products including baskets, eel traps (kypes), lobster pots, and furniture were widely made from willow throughout the area in the recent past. Among the more unusual products still made are passenger baskets for hot air balloons, the frames inside the Bearskins worn by the regiments of the Grenadier Guards, and an increasing number of willow coffins.Another use of willow has been found by the Coate family, who make artists' charcoals in Stoke St Gregory. It has become in 30 years the leading artists' charcoal manufacturer in Europe, producing most of the natural charcoals sold under different art-material brands.The industry is celebrated in the form of the Willow Man (sometimes known as the Angel of the South), a willow sculpture, 40 feet (12.2 m) tall, produced by artist Serena de la Hey in September 2000 that can be seen from the railway and the M5 motorway to the north of Bridgwater. At Stoke St Gregory there is also a Willows and Wetlands Visitor Centre.
[EX A]: What is the name of the family that is the leading artists' charcoal manufacturer in Europe?

[EX Q]: Passage: In the late 1830s, when much of the Old West was still Mexican territory, four people are traveling through the deserts, north of Texas and a three-day ride from Santa Fe.
One the Scalphunter, who says his trade is being a "buffaler" (buffalo hide trader). He is in search of gold. The others are a former ship Captain, also in search of the gold; the Woman from England, a former chambermaid who, in exchange for ship's passage to America, has signed an agreement to serve the Captain for five years as an indentured servant; and Mr. Rainbow, a former soldier who killed Indians.
The Captain sets out to find some of Montezuma's gold, risking danger from both the Native Indians and Mexican soldiers. The woman wants to get out of her contract with the Captain and go to New Orleans. She asks Mr. Rainbow to take her there, but he turns her down.
The Scalphunter wants half of the Captain's gold, and tags along with his men. Mr. Rainbow sets out across the desert through the Viaje de la Muerte, the Journey of Death.
[EX A]: What does the nickname for the trade of the man searching for gold actually refer to?

[EX Q]: Passage: The historic center of San Francisco is the northeast quadrant of the city anchored by Market Street and the waterfront. It is here that the Financial District is centered, with Union Square, the principal shopping and hotel district, and the Tenderloin nearby. Cable cars carry riders up steep inclines to the summit of Nob Hill, once the home of the city's business tycoons, and down to the waterfront tourist attractions of Fisherman's Wharf, and Pier 39, where many restaurants feature Dungeness crab from a still-active fishing industry. Also in this quadrant are Russian Hill, a residential neighborhood with the famously crooked Lombard Street; North Beach, the city's Little Italy and the former center of the Beat Generation; and Telegraph Hill, which features Coit Tower. Abutting Russian Hill and North Beach is San Francisco's Chinatown, the oldest Chinatown in North America. The South of Market, which was once San Francisco's industrial core, has seen significant redevelopment following the construction of AT&T Park and an infusion of startup companies. New skyscrapers, live-work lofts, and condominiums dot the area. Further development is taking place just to the south in Mission Bay area, a former railroad yard, which now has a second campus of the University of California, San Francisco, and where the new Warriors arena will be built.West of downtown, across Van Ness Avenue, lies the large Western Addition neighborhood, which became established with a large African American population after World War II. The Western Addition is usually divided into smaller neighborhoods including Hayes Valley, the Fillmore, and Japantown, which was once the largest Japantown in North America but suffered when its Japanese American residents were forcibly removed and interned during World War II. The Western Addition survived the 1906 earthquake with its Victorians largely intact, including the famous "Painted Ladies", standing alongside Alamo Square. To the south, near the geographic center of the city is Haight-Ashbury, famously associated with 1960s hippie culture. The Haight is now home to some expensive boutiques and a few controversial chain stores, although it still retains some bohemian character.
North of the Western Addition is Pacific Heights, an affluent neighborhood that features the homes built by wealthy San Franciscans in the wake of the 1906 earthquake. Directly north of Pacific Heights facing the waterfront is the Marina, a neighborhood popular with young professionals that was largely built on reclaimed land from the Bay.
