Official ExplanationThe key phrase here is
“cared deeply.” Someone who cared deeply about his art would be unlikely to work at it ambivalently (with mixed feelings about what he was doing). Likewise, someone who cared deeply about his art would be unlikely to work at it only intermittently (sporadically; at odd moments). No. We would expect someone with such deep feelings to work at his art
diligently (carefully, conscientiously).
“Despite” signals a contrast. The contrast is between Warhol’s deep feelings for his art and the appearance he affected or shammed. He tries to appear
nonchalant (unconcerned), and his affected nonchalance makes people who don’t look closely think he is indifferent (uncaring) about his paintings.
