Read the passage. The cartography essay opens with a familiar claim: maps help people find their way. It then complicates that claim by pointing out how a map's choices about scale, color, labels, and borders can make one feature appear central and another almost invisible. A transit map may enlarge downtown stations; a historical map may draw a boundary as if it were settled. The essay's main point is that maps do not merely display space. They guide attention and can quietly argue for a way of seeing it. Which choice best states the central idea of the entire passage about maps as arguments?
