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.

[EX Q]: 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.

[EX Q]: Question: Was WB Network more popular than Fox Television the year Black Family Channel folded? Passage:In 1987, Townsend wrote, directed and produced Hollywood Shuffle, a satire based on the hardships and obstacles that black actors undergo in the film industry. The success of his first project helped him establish himself in the industry. Another of his films was The Five Heartbeats based on 1960s R&B male groups and the tribulations of the music industry. Townsend created and produced two television variety shows—the CableACE award–winning Robert Townsend and His Partners in Crime for HBO, and the Fox Television variety show Townsend Television (1993). He also created and starred in the WB Network's sitcom The Parent 'Hood which originally ran from January 1995 to July 1999. In 2018, Townsend also directed 2 episodes for the B.E.T. Series American Soul which began airing in 2019. The show is about Don Cornelius and Soul Train. Townsend was programming director at the Black Family Channel, but the network folded in 2007. Townsend created The Robert Townsend Foundation, a nonprofit organization whose mission is to introduce and help new unsigned filmmakers.

[EX Q]: Question: When was the discovery of the base in DNA that is involved in the formation of 8-oxoguanine? Passage:The role of the deoxyriboside form of 8-oxoguanine, 8-oxo-2'-deoxyguanosine (abbreviated 8-oxo-dG or 8-OHdG) in cancer and aging also applies to 8-oxoguanine. Oxoguanine glycosylase is employed in the removal of 8-oxoguanine from DNA by the process of base excision repair. As described in oxoguanine glycosylase, deficient expression of this enzyme causes 8-oxoguanine to accumulate in DNA. This accumulation may then lead upon replication of DNA to mutations including some that contribute to carcinogenesis. 8-oxoguanine is usually formed by the interaction of reactive oxygen species (ROS) with the guanine base in DNA under conditions of oxidative stress; as noted in the article about them, such species may have a role in aging and male infertility, and 8-oxoguanine can be used to measure such stress.
