In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. 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: Does the college that Harrison graduated from in 1922 have more students than the one he graduated from in 1924? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Example Input: Question: How many world championships have been won by the team that the Reds outscored 22-8? Passage:On the mound, the Reds relied on left-handers Don Gullett and Fred Norman to pacify the Yankee hitters in Games 1 and 2, respectively. Gullett had come back from a mid-season injury to start Game 1 but had to leave the game in the eighth inning due to a twisted ankle while Norman out-pitched ace Hunter in Game 2. Game 3 in New York pitted effective 1976 NL Rookie of the Year Pat Zachry for the Reds against newly acquired Yankee, Dock Ellis. Ellis only lasted innings, exiting in the fourth after a home run by Driessen. Game 4 was delayed a day due to rain, but the Reds were ready for the sweep. Bench's two-run home run gave the Reds a 31 lead. In the bottom of the eighth, a frustrated Billy Martin threw a baseball from the dugout onto the field towards home plate umpire Bill Deegan, causing his ejection from the game. In the ninth, Bench's second home run followed by back-to-back doubles by Cesar Geronimo and Dave Concepcion made the score 72 and essentially blew the game open. The Cincinnati Reds outscored the New York Yankees, 228, and became the first NL team to repeat as World Champions since the 19211922 New York Giants. The Reds did not make a single offensive or defensive substitution (save pitching changes) during the entire series. Bench would claim the MVP of the series hitting .533 with two home runs and six runs batted in. His catching counterpart, Thurman Munson, had nine hits, all singles, and a .529 batting average.

Example Input: Question: How old was Rudi Gernreich when the monokini was introduced? Passage:By making an analogy with words like bilingual and bilateral containing the Latin prefix "bi-" (meaning "two" in Latin), the word bikini was first back-derived as consisting of two parts, [bi + kini] by Rudi Gernreich, who introduced the monokini in 1964. Later swimsuit designs like the tankini and trikini further cemented this derivation. Over time the "kini family" (as dubbed by author William Safire), including the "ini sisters" (as dubbed by designer Anne Cole), expanded into a variety of swimwear including the monokini (also known as a numokini or unikini), seekini, tankini, camikini, hikini (also hipkini), minikini, face-kini, burkini, and microkini. The Language Report, compiled by lexicographer Susie Dent and published by the Oxford University Press (OUP) in 2003, considers lexicographic inventions like bandeaukini and camkini, two variants of the tankini, important to observe. Although "bikini" was originally a registered trademark of Reard, it has since become genericized.
