For answer choice (E), I've read the explanations of why this clause is supported / why this answer choice is correct, but "to comment on society's values" is a bit of a stretch here, no? A commentary on societal values
really refers to something like dignity, human rights, morality, etc. An artistic statement on consumerist / materialistic culture would be pretty much the exact definition of a commentary on societal values, and the passage specifically relates that to some pop art and directly presents Lichtenstein's art as counter to that trend. I consequently eliminated this answer because I thought it was a Shell Game played with those details, which in my experience happens pretty frequently in RC:
But, in contrast to some pop art, Lichtenstein's work exuded not a jaded cynicism about consumer culture, but a kind of deliberate naivete
I understand now why the answer I chose -- A -- is incorrect, but at the time it seemed as though it was the least off-base answer of the 5, and to me it still seems as though "to comment on society's values" was a rather erroneous way for the test makers to have constructed a correct answer choice?
