Answer the question depending on the context.
Context: The peninsular borough's maritime heritage is acknowledged in several ways.The City Island Historical Society and Nautical Museum occupies a former public school designed by the New York City school system's turn-of-the-last-century master architect C. B. J. Snyder. The state's Maritime College in Fort Schuyler (on the southeastern shore) houses the Maritime Industry Museum. In addition, the Harlem River is reemerging as "Scullers' Row" due in large part to the efforts of the Bronx River Restoration Project, a joint public-private endeavor of the city's parks department. Canoeing and kayaking on the borough's namesake river have been promoted by the Bronx River Alliance. The river is also straddled by the New York Botanical Gardens, its neighbor, the Bronx Zoo, and a little further south, on the west shore, Bronx River Art Center.;
Question: Who designed the City Island Historical Society and Nautical Museum's building?;
If you can't find the answer, please respond "unanswerable".
Answer:
C. B. J. Snyder
The context mentions that the museum's building was designed by C. B. J. Snyder, who is also mentioned as a "master architect".
Therefore, we can conclude that he must have been quite renowned for his design work to be referred to in such way and therefore it makes sense for him to be an architect who is highly sought after or known for designing public buildings like schools and museums (as opposed to private residences)..
