In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: How old was Reg Smith the year he capped twice and scored 2 goals for England? Passage:In the 192526 season Millwall had 11 consecutive clean sheets, a Football League record, which they hold jointly with York City and Reading. Millwall became known as a hard-fighting Cup team and competed in various memorable matches, notably defeating three-time league winners and reigning champions Huddersfield Town 31 in the third round of the 192627 FA Cup. In the 192728 season Millwall won the Third Division South title and scored 87 goals at home in the league, an English record which still stands. Matches against Sunderland and Derby County saw packed crowds of 48,000-plus in the 1930s and 1940s. Their 1937 FA Cup run saw Millwall reach the semi-finals for the third time, and a fifth-round game against Derby still stands as Millwall's record attendance of 48,762. Millwall were the 11th best supported team in England in 1939, despite being in the Second Division. Millwall were one of the most financially wealthy clubs in England. The club proposed plans to improve the Den and signed international players. Winger Reg 'JR' Smith was capped twice, scoring two goals for England in 1938. The Lions were pushing for promotion to the First Division toward the end of the decade, but one week into the 193940 season, World War II broke out and Millwall were robbed of their aim.

Example Input: Question: The year that Debeaumarche was transported from Pantin to Buchenwald, which area was more populated during that time? Passage:He was arrested on 3 August 1944 at the Gare Montparnasse, and questioned harshly by the Gestapo at the Rue des Saussaies. He lost consciousness under the beatings but did not divulge any names; he was subsequently held at Fresnes Prison. Debeaumarche was one of the so-called "77,000" (named for the prisoners' numbers, between 76,000 and 78,000), Fresnes prisoners who were transported by train from Pantin to Buchenwald on 15 August 1944. He was moved to the underground factory of Mittelbau-Dora which produced V-1 flying bombs and V-2 rockets, and posing as an electrical engineer was put to work in the manufacture of the V-1. Maurice Naegele, a Kapo in the tunnel assembly section, gained the trust of Debeaumarche by relating details of the resistance movement in France. In fact Naegele had been an agent of the Gestapo, before his deportation. Naegele denounced Debeaumarche to SS-Oberscharfuhrer Sander, head of surveillance at Mittelbau-Dora. Debeaumarche was arrested with others (including Naegele) on the night of 34 November 1944. They were taken to the Niedersachswerfen SD headquarters, where Naegele attempted to beat confessions out of the other prisoners. Debeaumarche was sentenced to death on 11 November 1944, but the sentence was not carried out. Instead Debeaumarche was held in solitary confinement, accused of anti-Nazi plotting. In April 1945 he was moved to Bergen-Belsen, where he was liberated during the advance of Allied troops on 15 April 1945 and repatriated to France. On 1 May 1945 he marched down the Champs-Elysees alongside fellow Buchenwald-captive Pierre Dejussieu-Pontcarral.
Links: a. Oberscharfuhrer b. Pantin c. Buchenwald concentration camp d. Buchenwald concentration camp
Example Output: b

Example Input: Question: Who did West Germany defeat to win the 1954 FIFA World Cup in Switzerland? Passage:Following the end of World War II, Germany was partitioned into rival West and East zones, each with their own football systems. The general turmoil of the period and the country's lack of international footballing pedigree up to that point meant it was a surprise to many when West Germany won the 1954 FIFA World Cup in neighbouring Switzerland. It was in the mid-1960s when German football became very strong, with the backbone of the national squad formed by an exceptional group of young players at FC Bayern Munich, soon augmented further by another very strong team at Borussia Monchengladbach and others from the leading clubs. After reaching the 1966 FIFA World Cup Final, they built on victory in UEFA Euro 1972 by winning the 1954 FIFA World Cup on home soil. A further Euro win in 1980 (after an unexpected loss in the 1976 final), plus further World Cup final appearances in 1982 and 1986 confirmed their status as one of the world's most consistently powerful teams. With the end of the Cold War and reunification of the country approaching at the end of the 1980s, the final achievement of West Germany was winning the 1990 FIFA World Cup.
