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.

Passage: Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The influential San Francisco Planning and Urban Research Association or SPUR was founded in 1910 to address the quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights, where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendid Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.It was during this period San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy was hired by San Francisco Mayor James Rolph as chief engineer for the city in September 1912 to supervise the construction of the Twin Peaks Reservoir, the Stockton Street Tunnel, the Twin Peaks Tunnel, the San Francisco Municipal Railway, the Auxiliary Water Supply System, and new sewers. San Francisco's streetcar system, of which the J, K, L, M, and N lines survive today, was pushed to completion by O'Shaughnessy between 1915 and 1927. It was the O'Shaughnessy Dam, Hetch Hetchy Reservoir, and Hetch Hetchy Aqueduct that would have the largest effect on San Francisco. An abundant water supply enabled San Francisco to develop into the city it has become today.
In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San Francisco–Oakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937, respectively. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, the Birdman of Alcatraz. San Francisco later celebrated its regained grandeur with a World's fair, the Golden Gate International Exposition in 1939–40, creating Treasure Island in the middle of the bay to house it.
What is the name of the city that celebrated its rebirth at the Panama-Pacific International Exposition in 1915?

Passage: Bach is believed to have written Christ lag in Todes Banden in 1707. He was a professional organist aged 22, employed from 1703 in Arnstadt as the organist of the New Church (which replaced the burned Bonifatiuskirche, today known as the Bach Church). At age 18, he had inspected the new organ built by Johann Friedrich Wender, was invited to play one Sunday, and was hired. The organ was built on the third tier of a theatre-like church. Bach's duties as a church musician involved some responsibility for choral music, but the exact year he began composing cantatas is unknown. Christ lag in Todes Banden is one of a small group of cantatas that survive from his early years. According to the musicologist Martin Geck, many details of the score reflect "organistic practice".In Arnstadt, the Kantor (church musician) Heindorff was responsible for church music in the Upper Church (Liebfrauenkirche), and the New Church where Bach was the organist. He typically conducted music in the Upper Church and would appoint a choir prefect for vocal music in the New Church. Wolff notes that "subjecting his works to the questionable leadership of a prefect" was not what Bach would have done. Therefore, most cantatas of the period are not for Sunday occasions, but restricted to special occasions such as weddings and funerals. Christ lag in Todes Banden is the only exception, but was most likely composed not for Arnstadt but for an application to a more important post at the Divi Blasii church in Mühlhausen.
What was the name of the Bach Church when Bach was the organist?

Passage: The Trout Creek Mountains are a remote, semi-arid Great Basin mountain range mostly in southeastern Oregon and partially in northern Nevada in the United States. The range's highest point is Orevada View Benchmark, 8,506 feet (2,593 m) above sea level, in Nevada. Disaster Peak, elevation 7,781 feet (2,372 m), is another prominent summit in the Nevada portion of the mountains.
The mountains are characteristic of the Great Basin's topography of mostly parallel mountain ranges alternating with flat valleys. Oriented generally north to south, the Trout Creek Mountains consist primarily of fault blocks of basalt, which came from an ancient volcano and other vents, on top of older metamorphic rocks. The southern end of the range, however, features many granitic outcrops. As a whole, the faulted terrain is dominated by rolling hills and ridges cut by escarpments and canyons.
Most of the range is public land administered by the federal Bureau of Land Management.  There is very little human development in the remote region—cattle grazing and ranching are the primary human uses—but former mines at the McDermitt Caldera produced some of the largest amounts of mercury in North America in the 20th century. Public lands in the mountains are open to recreation but are rarely visited. Vegetation includes large swaths of big sagebrush in addition to desert grasses and cottonwood and alder stands. Sage grouse and mountain chickadee are two bird species native to the range, and common mammals include pronghorn and jackrabbits.
Despite the area's dry climate, a few year-round streams provide habitat for the rare Lahontan cutthroat trout. Fish populations in the Trout Creek Mountains declined throughout much of the 20th century. In the 1980s, the effects of grazing allotments on riparian zones and the fish led to land-use conflict.  The Trout Creek Mountain Working Group was formed in 1988 to help resolve disagreements among livestock owners, environmentalists, government agencies, and other interested parties. The stakeholders met and agreed on changes to land-use practices, and since the early 1990s, riparian zones have begun to recover.

What is name of the group that was formed to help solve issues among livestock owners and formed riparian zones?
