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: Which was created first, Little Quacker (1950) or The Yogi Bear Show? Passage:Another recurring character in the series was Little Quacker the duckling, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker (1950), Just Ducky (1953), Downhearted Duckling (1954), Southbound Duckling (1955), That's My Mommy (also 1955), Happy Go Ducky (1958), and The Vanishing Duck (1958). Quacker talks a lot compared to Tom and Jerry. His voice is a 'duck voice' not dissimilar to Disney's Donald Duck. In many shorts, he is the only character who speaks. He is very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He is a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. He appeared in The Tom and Jerry Show episode "The Lost Duckling" (1975). He also got his own series of shorts on The Yogi Bear Show (renamed Yakky Doodle) after guesting in several Hanna-Barbera TV shows. Quacker was then used as a template for the 'Hard Luck Duck' character starring in the titular character's short from the What a Cartoon! series. His What a Cartoon! counterpart Hard Luck Duck was voiced by Russi Taylor.

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: What country did Li Yuru have a successful 48-day run of 62 plays in? Passage:Graduating at age 17 in 1940, she established her own troupe with friends from the school. She organised a program of 62 new and traditional plays over a successful 48-day run in Shanghai, starring in 28 of them. Disliking the pressure she came under as an independent young actress, she disbanded the troupe and placed herself under the training and protection of older male actors: Xun Huisheng and Mei Lanfang, two of the "Four Great Dan"; Zhao Tongshan, the greatest "flowery" actor of the time; the "martial clown" Ye Shengzhang; the "educated clown" Ma Fulu; the "painted face" actor Jin Shaoshan; the "martial" actor Li Shaochun; the "Four Great Beards" Ma Lianliang, Tan Fuying, Yang Baosen, and Xi Xiaobo; and the other "old men" Zhou Xinfang and Tang Yunsheng. She also studied under the female impersonators Yu Lianquan and Cheng Yanqiu. The broad range of specialists expanded her repertoire greatly. During this period, Li gave successful performances of The Dragon and the Phoenix, The Courtyard of the Black Dragon, Two Phoenixes Flying Together, and Three Pretty Women. Her career and finances were largely handled by her mother, who was reckoned one of the "Four Famous Mothers" of the opera. She had her first daughter Li Li in 1944.
