  3. Correct

    Only art that involves original

    Why this is right

    We can't derive any connection between original ideas and influential. It's very possible that some influential art doesn't involve original ideas. That doesn't go against anything in the stimulus. There could be art that is influential, but not great, and so it might not have any original ideas (like Taylor Swift's music, just kidding Swifties don't murder me).

    Skill tested: Must be True · how this choice captures the argument's function is the move to repeat next time.

  4. Only art that is influential

    This can be inferred from the GA → OI second and third statements. GA → I GA → I + OI

    13% picked this

  5. Some twentieth-century art is influential

    Must Be True

    This can be inferred from 20th ↢some↣ GA all three statements. GA → OI GA → I ∴ 20th ↢some↣ I + OI
