Critic: Photographers, by deciding which subjects to depict and how to depict them, express their own worldviews in their photographs, however realistically those photographs may represent reality. Thus, photographs are interpretations of reality. The argument's conclusion is properly drawn if which one of the following is assumed? ['To express a worldview is to interpret reality.', "All visual art expresses the artist's worldview.", 'Any interpretation of reality involves the expression of a worldview.', 'Nonrealistic photographs, like realistic photographs, express the worldviews of the photographers who take them.']
