Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Of the three cups University College Dublin competed in, which cup was established first? Passage:University College Dublin A.F.C. was founded in 1895 as the Catholic University Medical School Football Club. They began playing regular games the following year. A First XI played College games against other Universities and a Second XI entered outside competitions. The club was founder members of the Leinster Junior League in 1896 and reached the semi-finals of the Leinster Senior Cup in 1897. The club became University College Dublin when the new University annexed the Medical school in 1908. UCD won the inaugural Intervarsities competition, the Collingwood Cup, in 1914 and added the Irish Intermediate Cup the following year beating Portadown 2–1 in a replayed final. When the Irish Free State was formed in 1921 and the new Football Association of Ireland was formed, UCD participated in the Preliminary round against fellow non-League team Shamrock Rovers in November 1921. The game took place in Windy Arbour and the Hoops won 6–2. UCD were invited to join the League of Ireland in 1922, but had to turn it down on the basis of not being able to field a team in the League of Ireland Shield in September as the Academic year didn't commence until October. In 1945 they won the FAI Intermediate Cup when UCD beat fellow future League of Ireland members Cobh Ramblers 4–2 in the final. UCD appeared in the FAI Cup in the 1930s, 1940s and 1950s, their final appearance as a non-League outfit coming in 1957 when Cork Athletic beat UCD 4–2 in the Mardyke.

Example Input: Question: Who was the other finalist in the 1930 Allan Cup other than the team Roche was on? Passage:Roche was born in Prescott, Ontario, but moved to Montreal where he played junior hockey for the Montreal Victorias and other teams. He moved up to senior hockey for the Montreal Hockey Club and played for their Allan Cup-winning squad of 1930. He signed with the Maroons of the NHL, playing for the Maroons and the Windsor Bulldogs until 1933. He was released by the Maroons and signed with the Bruins in January 1933 only to be traded to the Senators one month later. In his one full season with the Senators in 1933–34 he showed a scoring touch, scoring 13 goals and 16 assists in 45 games. The next season, the Senators relocated to St. Louis to become the Eagles. Roche was traded twice in 1934–35; from St. Louis to Buffalo, then to the Red Wings. That marked his last season in the NHL, as he subsequently played for various minor-league pro teams until 1942.

Example Input: Question: What was size of the largest telescope in operation when the photographic plates of Zeta Aurigae were exposed? Passage:Zeta Aurigae was first recognized as a spectroscopic binary by William Hammond Wright while analyzing photographic plates taken at Lick Observatory between 1898 and 1908. This star is among those earlier described by Antonia Maury as having a composite spectrum. The first orbit was determined in 1924 by William Edmund Harper using measurements taken at Dominion Observatory, his orbital elements are very similar to the most recent determinations. Harper also noticed that the composite nature of the spectrum had disappeared on the one plate when the K type primary was nearest the sun indicating a possible eclipse. In 1932 the eclipsing binary nature of the system was confirmed by Paul Guthnick, Heribert Schneller and independently Josef Hopmann.
