Choice D is the best answer. In lines 83-90("Media...postings"), the author of Passage 2 criticizes media critics for their alarmist writing: "Media critics write as if the brain takes on the qualities of whatever it consumes, the informational equivalent of 'you are what you eat.' " The author then compares media critics'"you are what you eat" mentality to ancient people's belief that "eating fierce animals made them fierce." The author uses this analogy to discredit media critics' belief that consumption of electronic media alters the brain.
Choices A, B, and C are incorrect because the final sentence of Passage 2 does not use ornate language, employ humor, or evoke nostalgia for the past.
