If you want to know the year of the latest revision of the quad, which element would you consult?

Explanation:
Maps carry metadata about when they were created or updated, and that information is found where the map’s basic details are shown. The title block is the part of a quad that lists the map’s title, publication date, edition, and revision year. That makes it the go-to place to learn the year of the latest revision, so you can judge how current the data is. The legend explains symbols, the scale shows the distance relationship, and contour lines depict terrain elevations; none of these indicate when the map was last revised. So the year of the latest revision is found in the title block.
