Input: Consider Input: Passage: Recording sessions for The Joshua Tree began in January 1986 in Danesmoate House in Dublin and continued throughout the year. U2 briefly interrupted these sessions in June to join Amnesty International's A Conspiracy of Hope tour of benefit concerts. Following the first concert in San Francisco, lead singer Bono met René Castro, a Chilean mural artist. Castro had been tortured and held in a concentration camp for two years by the dictatorial Chilean government because his artwork criticised the Pinochet-led regime that seized power in 1973 during a coup d'état. Castro showed Bono a wall painting in the Mission District that depicted the ongoing plight in Chile and Argentina. He also learned of the Madres de Plaza de Mayo, a group of women whose children were forcibly disappeared by the Argentine government. The Madres' children were students who had opposed the government during the Dirty War, and the coup d'état that brought Jorge Rafael Videla to power. The Madres joined together to campaign for information regarding the locations of their children's bodies and the circumstances of their deaths, believing them to have been kidnapped, tortured, and murdered.Inspired by the mural, Bono took an extended break from recording into July, traveling to Nicaragua and El Salvador with his wife, Alison Hewson, to see first-hand the distress of peasants bullied by political conflicts and US military intervention. While there, they worked with the Central American Mission Partners (CAMP), a human rights and economic development organization. In El Salvador they met members of the Comité de Madres Monsignor Romero (COMADRES: Committee of the Mothers Monsignor Romero), an organization of women whose children were forcibly disappeared by the Salvadoran government during the Civil War because they opposed the military regime that was in power. At one point during the trip, Bono, Alison, and a member of CAMP were shot at by government troops while on their way to deliver aid to a group of farmers. The shots were a warning and, according to author John Luerssen, the incident made Bono realize that "they didn't care for their intrusion and they could kill them if they felt compelled."In 2006, Bono recounted another experience he had in El Salvador, where he had seen a body thrown from a van into the road. He remarked, "People would just disappear. If you were part of the opposition, you might find an SUV with the windows blacked out parked outside your house.... If that didn't stop you, occasionally they would come in and take you and murder you; there would be no trial." Bono understood the cause of the Madres and COMADRES and wanted to pay tribute to it. His experiences in Central America inspired the lyrics of "Mothers of the Disappeared" and another track from The Joshua Tree, "Bullet the Blue Sky". 
Question: What is the first name of the person who was held in a concentration camp for two years by the dictatorial Chilean government?

Output: René.


Input: Consider Input: Passage: New York City's Central Park, an oasis that functions as the city's "green lung", was in a state of deterioration in the mid-1970s. Though Central Park had been designated a National Historic Landmark in 1962, at the start of the 1980s, the city lacked the financial resources to spend an estimated US$3,000,000 to restore or even to maintain the park. The nonprofit Central Park Conservancy was founded in 1980, and began a successful campaign to raise renovation funds.In the early 1980s, Parks Commissioner Gordon Davis, responsible for New York City's green areas, and Ron Delsener, one of the city's most influential concert promoters, developed the idea of helping Central Park financially with a free open-air concert, under the legal guidance of Bob Donnelly. The city would use profits from merchandising, television, and video rights to renovate the park. Earlier park performances by Elton John and James Taylor showed that this concept could be a success. Davis authorized the project, and Delsener entered discussions with cable TV channel HBO to decide who would perform.They decided on Simon & Garfunkel, a group that had formed in New York City in the 1960s, and had been one of the most successful folk rock groups through the late 60s/early 70s. Simon & Garfunkel had broken up at the height of their popularity and shortly after the release of their fifth studio album, Bridge Over Troubled Water, which is deemed to be their artistic peak and which topped the 1970 Billboard charts for ten weeks. They had grown apart artistically and did not get along well with each other. In the following eleven years, both continued musical careers as solo artists, and worked together only sporadically on single projects. Garfunkel made brief guest appearances at Simon's concerts, which were always successful.Delsener presented the plan to Paul Simon in the summer of 1981. Simon was enthusiastic about the idea, but questioned whether it could be financially successful, especially given the poor audience attendance of his last project, the autobiographical movie One-Trick Pony. Simon's confidence had declined and he had sought treatment for depression. He questioned whether he and Art Garfunkel could work together, but contacted Garfunkel, who was vacationing in Switzerland. Garfunkel was excited about the idea, and immediately returned to the US.From the promoter's viewpoint, Simon and Garfunkel were ideal choices. Not only were they likely to draw a large crowd to the concert, they also had roots in the city –  both had grown up and gone to school in Forest Hills, Queens. Music critic Stephen Holden pointed out that, unlike artists who had left in pursuit of lifestyles offered by other locales, the two had always been a part of New York City. Both gained inspiration from the cityscape and the cultural variety of New York, and spoke of these influences in their songs. 
Question: What is the name of the city that lacked the financial resources to spend an estimated US$3,000,000 to restore or even maintain its "green lung" at the start of the 1980s??

Output: New York City.


Input: Consider Input: Passage: Shoshone National Forest is an integral part of the Greater Yellowstone Ecosystem, which has 1,700 documented species of plants. Since the elevation of the land in the forest ranges from 4,600 to 13,804 ft (1,402 to 4,207 m), which is more than 9,000 ft (2,700 m), the forest has a wide variety of ecosystems. Lower elevations often have sagebrush and grass-dominated vegetation types, while forested areas are dominated by various combinations of tree and shrub species. These include lodgepole pine, which along with Rocky Mountain juniper, and quaking aspen are found at elevations up to 9,000 ft (2,700 m). At higher elevations subalpine fir, Engelmann spruce, whitebark pine and limber pine, are common, each occurring up to timberline. The region above timberline makes up 25 percent of the total acreage of the forest and of that 13 percent is listed as just either barren, rock or ice. The types of plant species is highly dependent on the amount of water available, and trees are more commonly found on higher slopes due to the longer lasting snowfall which keeps the soil moister for a longer time into the summer months. Along lower elevation riparian corridors, cottonwoods and willows are typically dominant. Numerous plant species are endemic to the region including some that are rare. Among them, the whitlow grass, fremont bladderpod, shoshonea, and the north fork Easter daisy provide vivid white and yellow flowers during the spring and summer.Exotic species of flora that are not native to the region include Canada thistle, Musk thistle, Spotted knapweed, Leafy spurge and Yellow toadflax. These non-native plant species are considered noxious, impacting native plant communities and the species that thrive on them. Native species such as the mountain pine beetle are having an enormous negative impact on some tree species. A survey of the forest performed in 2010 indicated that over 1,000,000 acres (400,000 ha) of timberland had been impacted by insects such as the mountain pine beetle, spruce bark beetle and Douglas fir beetle, and that the insects had killed between 25 and 100 percent of the trees in the impacted areas. The forest service is addressing the situation by performing controlled burns, selling dead trees as firewood, timber harvesting and spraying the highest value areas. 
Question: What types of various trees and shrub species dominate the forest areas at higher elevations but below timberline??


Output: subalpine fir.
