Input: Consider Input: Question: What was the founding date of the team Foster played against in the 2001 FA Trophy final? Passage:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.

Input: Consider Input: Question: Who won the World Cup where the Costa Rican team had a prominent performance? Passage:Since the late 1980s, the team has continuously been visible as a solidly competitive side, with a prominent performance in the 1990 FIFA World Cup in Italy, making it to the knockout stage in their debut after finishing second in their group during the first phase, below Brazil. They also managed to qualify for the 2002 and 2006 FIFA World Cups. In 2014, Costa Rica made their best performance in history by finishing first in their group that consisted of three former World Cup champions: Uruguay, Italy, and England. During the Round of 16 they defeated Greece 5–3 via a penalty shootout after a 1–1 draw. Moreover, during the match against a much better team, Navas saved more than 15 shots due to the Costa Rican very weak defense. The match was characterized as "Navas vs Greece". They reached the quarterfinals for the very first time as the Ticos were defeated by the Netherlands also in a penalty shootout (3–4) after a scoreless draw on 5 July. Their 2018 World Cup campaign ended in a 4th place group stage exit with their only point coming from a 2-2 draw vs Switzerland.

Input: Consider Input: Question: How old was Pierre Dejussieu-Pontcarral when he marched with Debeaumarché down the Champs-Élysées? 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. Debeaumarché 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 Naegelé, a Kapo in the tunnel assembly section, gained the trust of Debeaumarché by relating details of the resistance movement in France. In fact Naegelé had been an agent of the Gestapo, before his deportation. Naegelé denounced Debeaumarché to SS-Oberscharführer Sander, head of surveillance at Mittelbau-Dora. Debeaumarché was arrested with others (including Naegelé) on the night of 3–4 November 1944. They were taken to the Niedersachswerfen SD headquarters, where Naegelé attempted to beat confessions out of the other prisoners. Debeaumarché was sentenced to death on 11 November 1944, but the sentence was not carried out. Instead Debeaumarché 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-Élysées alongside fellow Buchenwald-captive Pierre Dejussieu-Pontcarral.
