Problem: Background: Andy Warhol (; born Andrew Warhola; August 6, 1928 - February 22, 1987) was an American artist, director and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966-67). Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator.
Context: Warhol died in Manhattan at 6:32 a.m. on February 22, 1987 at age 58. According to news reports, he had been making a good recovery from gallbladder surgery at New York Hospital before dying in his sleep from a sudden post-operative irregular heartbeat. Prior to his diagnosis and operation, Warhol delayed having his recurring gallbladder problems checked, as he was afraid to enter hospitals and see doctors. His family sued the hospital for inadequate care, saying that the arrhythmia was caused by improper care and water intoxication. The malpractice case was quickly settled out of court; Warhol's family received an undisclosed sum of money. Shortly before Warhol's death, doctors expected Warhol to survive the surgery, though a revaluation of the case about thirty years after his death showed many indications that Warhol's surgery was in fact riskier than originally thought. It was widely reported at the time that Warhol died of a "routine" surgery, though when considering factors such as his age, a family history of gallbladder problems, his previous gunshot wounds, and his medical state in the weeks leading up to the procedure, the potential risk of death following the surgery appeared to have been significant. Warhol's brothers took his body back to Pittsburgh, where an open-coffin wake was held at the Thomas P. Kunsak Funeral Home. The solid bronze casket had gold-plated rails and white upholstery. Warhol was dressed in a black cashmere suit, a paisley tie, a platinum wig, and sunglasses. He was laid out holding a small prayer book and a red rose. The funeral liturgy was held at the Holy Ghost Byzantine Catholic Church on Pittsburgh's North Side. The eulogy was given by Monsignor Peter Tay. Yoko Ono and John Richardson were speakers. The coffin was covered with white roses and asparagus ferns. After the liturgy, the coffin was driven to St. John the Baptist Byzantine Catholic Cemetery in Bethel Park, a south suburb of Pittsburgh. At the grave, the priest said a brief prayer and sprinkled holy water on the casket. Before the coffin was lowered, Paige Powell dropped a copy of Interview magazine, an Interview T-shirt, and a bottle of the Estee Lauder perfume "Beautiful" into the grave. Warhol was buried next to his mother and father. A memorial service was held in Manhattan for Warhol on April 1, 1987, at St. Patrick's Cathedral, New York.
Question: Cause of death
Answer: he had been making a good recovery from gallbladder surgery at New York Hospital before dying in his sleep from a sudden post-operative irregular heartbeat.

Problem: Background: Richard of Bordeaux was the younger son of Edward, the Black Prince, and Joan of Kent. Edward, heir apparent to the throne of England, had distinguished himself as a military commander in the early phases of the Hundred Years' War, particularly in the Battle of Poitiers in 1356. After further military adventures, however, he contracted dysentery in Spain in 1370. He never fully recovered and had to return to England the next year.
Context: Richard gradually re-established royal authority in the months after the deliberations of the Merciless Parliament. The aggressive foreign policy of the Lords Appellant failed when their efforts to build a wide, anti-French coalition came to nothing, and the north of England fell victim to a Scottish incursion. Richard was now over twenty-one years old and could with confidence claim the right to govern in his own name. Furthermore, John of Gaunt returned to England in 1389 and settled his differences with the king, after which the old statesman acted as a moderating influence on English politics. Richard assumed full control of the government on 3 May 1389, claiming that the difficulties of the past years had been due solely to bad councillors. He outlined a foreign policy that reversed the actions of the appellants by seeking peace and reconciliation with France, and promised to lessen the burden of taxation on the people significantly. Richard ruled peacefully for the next eight years, having reconciled with his former adversaries. Still, later events would show that he had not forgotten the indignities he perceived. In particular, the execution of his former teacher Sir Simon de Burley was an insult not easily forgotten. With national stability secured, Richard began negotiating a permanent peace with France. A proposal put forward in 1393 would have greatly expanded the territory of Aquitaine possessed by the English crown. However, the plan failed because it included a requirement that the English king pay homage to the King of France - a condition that proved unacceptable to the English public. Instead, in 1396, a truce was agreed to, which was to last 28 years. As part of the truce, Richard agreed to marry Isabella, daughter of Charles VI of France, when she came of age. There were some misgivings about the betrothal, in particular because the princess was then only six years old, and thus would not be able to produce an heir to the throne of England for many years. Although Richard sought peace with France, he took a different approach to the situation in Ireland. The English lordships in Ireland were in danger of being overrun, and the Anglo-Irish lords were pleading for the king to intervene. In the autumn of 1394, Richard left for Ireland, where he remained until May 1395. His army of more than 8,000 men was the largest force brought to the island during the late Middle Ages. The invasion was a success, and a number of Irish chieftains submitted to English overlordship. It was one of the most successful achievements of Richard's reign, and strengthened the king's support at home, although the consolidation of the English position in Ireland proved to be short-lived.
Question: Was his foreign policy successful?

Richard began negotiating a permanent peace with France.
