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 Input:
Passage: Washington, D.C. is located in the mid-Atlantic region of the U.S. East Coast. Due to the District of Columbia retrocession, the city has a total area of 68.34 square miles (177.0 km2), of which 61.05 square miles (158.1 km2) is land and 7.29 square miles (18.9 km2) (10.67%) is water. The District is bordered by Montgomery County, Maryland to the northwest; Prince George's County, Maryland to the east; Arlington County, Virginia to the south; and Alexandria, Virginia to the west.
The south bank of the Potomac River forms the District's border with Virginia and has two major tributaries: the Anacostia River and Rock Creek. Tiber Creek, a natural watercourse that once passed through the National Mall, was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and was used during the 19th century to bypass the Little Falls of the Potomac River, located at the northwest edge of Washington at the Atlantic Seaboard fall line.The highest natural elevation in the District is 409 feet (125 m) above sea level at Fort Reno Park in upper northwest Washington. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L Streets NW.The District has 7,464 acres (30.21 km2) of parkland, about 19% of the city's total area and the second-highest percentage among high-density U.S. cities. This factor contributed to Washington, D.C., being ranked as third in the nation for park access and quality in the 2018 ParkScore ranking of the park systems of the 100 most populous cities in the United States, according to the nonprofit Trust for Public Land.The National Park Service manages most of the 9,122 acres (36.92 km2) of city land owned by the U.S. government. Rock Creek Park is a 1,754-acre (7.10 km2) urban forest in Northwest Washington, which extends 9.3 miles (15.0 km) through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes. Other National Park Service properties include the C&O Canal National Historical Park, the National Mall and Memorial Parks, Theodore Roosevelt Island, Columbia Island, Fort Dupont Park, Meridian Hill Park, Kenilworth Park and Aquatic Gardens, and Anacostia Park. The D.C. Department of Parks and Recreation maintains the city's 900 acres (3.6 km2) of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers. The U.S. Department of Agriculture operates the 446-acre (1.80 km2) U.S. National Arboretum in Northeast Washington.

Ex Output:
What is the country's fourth-oldest national park?

Passage: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the Mono–Inyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,—cinders and ashes scattered on glacier-polished pavements,—frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire."  Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".

Ex Output:
What is the name of the place that has two volcanic islands?

Passage: In the late 1970s the genre failed to help the economy, with punk music being anti-conformity and anti-mainstream they failed to get into the commercial music. By the 1990s, punk rock was sufficiently ingrained in Western culture that punk trappings were often used to market highly commercial bands as "rebels". Marketers capitalized on the style and hipness of punk rock to such an extent that a 1993 ad campaign for an automobile, the Subaru Impreza, claimed that the car was "like punk rock".In 1993, California's Green Day and Bad Religion were both signed to major labels. The next year, Green Day put out Dookie, which became a huge hit, selling nine million albums in the United States in just over two years. Bad Religion's Stranger Than Fiction was certified gold. Other California punk bands on the independent label Epitaph, run by Bad Religion guitarist Brett Gurewitz, also began achieving mainstream popularity. In 1994, Epitaph released Let's Go by Rancid, Punk in Drublic by NOFX, and Smash by the Offspring, each eventually certified gold or better. That June, Green Day's "Longview" reached number one on Billboard's Modern Rock Tracks chart and became a top forty airplay hit, arguably the first ever American punk song to do so; just one month later, the Offspring's "Come Out and Play" followed suit. MTV and radio stations such as Los Angeles' KROQ-FM played a major role in these bands' crossover success, though NOFX refused to let MTV air its videos.
The Offspring's 1998 album Americana, released by the major Columbia label, debuted at number two on the album chart. A bootleg MP3 of Americana's first single, "Pretty Fly (for a White Guy)", made it onto the Internet and was downloaded a record 22 million times—illegally. The following year, Enema of the State, the first major-label release by pop punk band Blink-182, reached the top ten and sold four million copies in under twelve months. On February 19, 2000, the album's second single, "All the Small Things", peaked at number 6 on the Billboard Hot 100. While they were viewed as Green Day "acolytes", critics also found teen pop acts such as Britney Spears, the Backstreet Boys, and 'N Sync suitable points of comparison for Blink-182's sound and market niche. The band's Take Off Your Pants and Jacket (2001) and Blink-182 (2003) respectively rose to numbers one and three on the album chart. In November 2003, The New Yorker described how the "giddily puerile" act had "become massively popular with the mainstream audience, a demographic formerly considered untouchable by punk-rock purists.".
