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

Passage: In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrović has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for a last sojourn on the surface. Crewmate Richard Harrington drives Petrović in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrović.
Captain Charles Brunel and crewmate Lauren Dalby plan to explore the pit to retrieve Petrović's body. Dalby remains at the pit but disappears before the team can return with equipment. Brunel authorizes Vincent Campbell to explore the pit and he finds a fungus-like life that grows in the fissure. Dalby and Petrović reappear at the main outpost, but the Martian bacteria has mutated them into fast, aggressive, zombie-like creatures with blackened skin and no trace of their original personalities. Harrington dies from a power drill attack by one of the zombies and later revives as one himself. The remaining crew hold off the zombies while Brunel and Campbell return. Brunel is also fatally injured and reanimates, which provides the crew with new insight into the symptoms: thirst, memory loss and aggression.
What is the full name of the person who obtained the soil with the biological agent?

Passage: Shortly after the return home in November 1936 Riley, together with three other Jarrow councillors who had led the march—James Hanlon, Paddy Scullion and Joseph Symonds—left Labour to form a breakaway group committed to a more direct fight for employment. All four later rejoined the party; Scullion and Symonds both served as the town's mayor, and Symonds was Labour MP for Whitehaven from 1959 to 1970. In 1939 Wilkinson published her history of Jarrow, The Town that Was Murdered. A reviewer for The Economic Journal found the book "not quite as polemical as one might have expected", but felt that in her denunciation of the BISF Wilkinson had not taken full account of the state of the iron and steel industry in the 1930s. Wilkinson continued her parliamentary career, and from 1940 to 1945 held junior ministerial office in Churchill's wartime coalition government. In the 1945 Labour government she was appointed Minister of Education, with a seat in the cabinet, a post in which she served until her death, aged 55, in February 1947.
In 1974 the rock singer Alan Price released  the "Jarrow Song", which helped to raise awareness of the events of 1936 among a new generation. Among dramatisations based on the Jarrow March is a play, Whistling at the Milestones (1977) by Alex Glasgow, and an opera, Burning Road (1996), by Will Todd and Ben Dunwell. In what Perry describes as one of the ironies surrounding the march, the opera was performed in Durham Cathedral in May 1997, in retrospective defiance of the bishop who had condemned the march. On 29 October 2017, the Tyne Bridge was closed off and was the venue the Freedom on The Tyne Finale. The Freedom on The Tyne Finale was the finale of the 2017 Freedom City festival. The event, promoted by Newcastle University re-enacted many world civil rights stories throughout history. The final event, revolved around the March, the re-enactment was described as a memorable closing to the finale. The town of Jarrow contains several commemorations, including a steel relief sculpture by Vince Rea at the new railway station, a tile mural designed by local schoolchildren, and a bronze sculpture—"The Spirit of the Crusade" by Graham Ibbeson—in the town centre. Buildings and street names bear the names of Wilkinson and Riley. Perry writes that "In Jarrow, landscape and memory have fused together, just as the red hot rivets once fastened great sheets of steel in Palmer's Yard.".
What were the last names of the four people that led the march and formed a breakaway group?
