instruction:
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.

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".
answer:
What is the first name of the person whose artwork criticized the Pinochet-led regime that seized power in 1973?


question:
Passage: The Stooges are wannabe detectives who inadvertently get their chance to crack a case in Scotland. They manage to stumble on a lead concerning the priceless Punjab diamond being stolen by a crook named Dapper. With dreams of becoming genuine detectives, the trio head for Squid McGuffy's cafe asking for the whereabouts of Dapper. They manage to convince everyone at the restaurant that they are actually police.
While searching several rooms above the cafe, the Stooges stumble on Dapper's moll, who hastily hides the Punjab diamond in a candy dish. The boys refuse to leave, suspecting Dapper will eventually show his face. While killing time, Shemp starts to flirt with the moll, and manages to swallow the ice along with some mints from the candy dish. The gal nearly has a nervous breakdown but quickly discovers the Stooges are not actually real detectives. She calls in Dapper and his henchman Muscles and frantically try to pry the diamond out of frazzled Shemp.
After all else fails, Dapper decides to cut him open. Moe and Larry are locked in a closet by Muscles while Shemp is tied down on a close by desk-turned-operating table. As luck would have it, there happen to be a bag of tools in the closet, which Moe and Larry use to saw their way out of the closet, and right into a gorilla's cage on the other side of the wall. The gorilla knocks Moe, Larry, Dapper and Muscles cold. The beast, however, befriends Shemp, and helps him cough up the diamond. Moments later, Shemp explains how he managed to swallow the diamond by actually doing so again.
answer:
Who swallows the Punjab diamond?


question:
Passage: Big Star was an American rock band formed in Memphis, Tennessee, in 1971 by Alex Chilton, Chris Bell, Jody Stephens, and Andy Hummel. The group broke up in early 1975, and reorganized with a new lineup 18 years later following a reunion concert at the University of Missouri. 
In its first era, the band's musical style drew on the Beatles, the Rolling Stones, and the Byrds. Big Star produced a style that foreshadowed the alternative rock of the 1980s and 1990s. Before it broke up, Big Star created a "seminal body of work that never stopped inspiring succeeding generations," in the words of Rolling Stone, as the "quintessential American power pop band," and "one of the most mythic and influential cult acts in all of rock & roll".Big Star's first album—1972's #1 Record—was met by enthusiastic reviews, but ineffective marketing by Stax Records, and limited distribution stunted its commercial success. Frustration took its toll on band relations: Bell left not long after the first record's commercial progress stalled, and Hummel left to finish his college education after a second album, Radio City, was completed in December 1973. Like #1 Record, Radio City received excellent reviews, but label issues again thwarted sales—Columbia Records, which had assumed control of the Stax catalog, likewise effectively vetoed its distribution. 
After a third album, recorded in the fall of 1974, was deemed commercially unviable and shelved before receiving a title, the band broke up late in 1974. Four years later, the first two Big Star LPs were released together in the UK as a double album. The band's third album was finally issued soon afterward; titled Third/Sister Lovers, it found limited commercial success, but has since become a cult classic. Shortly thereafter, Chris Bell was killed in a car accident at the age of 27.
During the group's hiatus in the 1980s, the Big Star discography drew renewed attention when R.E.M. and the Replacements, as well as other popular bands, cited the group as an influence. In 1992, interest was further stimulated by Rykodisc's reissues of the band's albums, complemented by a collection of Bell's solo work.In 1993, Chilton and Stephens reformed Big Star with recruits Jon Auer and Ken Stringfellow of the Posies, and gave a concert at the University of Missouri. The band remained active, performing tours in Europe and Japan, and released a new studio album, In Space, in 2005. Chilton died in March 2010 after suffering from heart problems. Hummel died of cancer four months later. These deaths left Stephens as the sole surviving founding member. Big Star was inducted into the Memphis Music Hall of Fame in 2014.
Since December 2010, several surviving members have appeared in a series of live tribute performances of the album Third/Sister Lovers, under the billing "Big Star's Third". As of 2017, that project has remained active.
answer:

What is the first name of the person who left not long after the first record's commercial progress stalled?
