Answer:
Museums influence the way we view and understand works of art by giving either giving us sterile environments to view the work without biases influencing us, as well as provide information about the piece to better understand it, or by placing it an environment which allows us to immerse ourselves and understand the piece better when it is paired with things that match its vision (i.e. a French revolution painting being put in a French section of a museum or religious statues being put together in a room) museums can be objective sources of knowledge because they simply provide the background information on a painting, with subjective knowledge usually optional in the form of tours and such.
