Art critic: Support Abstract paintings are nonrepresentational, and so the only measure of their worth is their interplay of color, texture, and form. ███ ███ █ ████████ ██ ████ ███ ██████ ██ █████████ ███████ █████████ ██ ██████ █████████ ████ ██ ███ ████ ████████████ ███ ████ ███████ ██████████████ ██ █████ ██████████ ████████ ████████ ███ █████ ██ █ ███████████ ███████████ ███ █████
The art critic concludes that abstract painting can never be a politically significant art form. Why? Because, for a painting to inspire political action, it must clearly represent scenes of injustice. And abstract painting is nonrepresentational. 
The conclusion is about being politically significant, but the support is about inspiring political action. We don’t know that those are identical. Therefore, the author must be assuming that, if a painting can’t inspire political action, it isn’t politically significant art. (The contrapositive: being politically significant requires inspiring political action.) Note that this assumption is both necessary and sufficient to prove the argument’s conclusion.
