Question: Which of the 1900 public parks in New York is the Grey Art Gallery located in? 

full_context: Document 1: Grey Art Gallery: The Grey Art Gallery is New York University’s fine art museum, located on historic Washington Square Park, in New York City’s Greenwich Village. As a university art museum, the Grey Art Gallery functions to collect, preserve, study, document, interpret, and exhibit the evidence of human culture. While these goals are common to all museums, the Grey distinguishes itself by emphasizing art’s historical, cultural, and social contexts, with experimentation and interpretation as integral parts of programmatic planning. Thus, in addition to being a place to view the objects of material culture, the Gallery serves as a museum-laboratory in which a broader view of an object’s environment enriches our understanding of its contribution to civilization.
