🔍 Key Concepts

• Chart marginal information (where titles, notes, and publication data are shown) • Difference between chart title area and other corners or edges • How edition dates and revision information are usually presented on official NOAA or Admiralty charts

💭 Think About

• Before looking at the choices, picture a standard paper nautical chart on a chart table. Where do you normally see the title, scale, and publication notes printed? • Ask yourself: is the revision date treated more like a random note anywhere on the chart, or is it grouped with other formal information such as title, publisher, and scale? • Think about which part of the chart is designed for text blocks and reference info versus areas reserved for depth soundings and navigation features.

✅ Before You Answer

• Identify which answer choice corresponds to the main information block where chart title, scale, and publisher appear. • Eliminate any options that would place important publication data in an area that might be obscured by plotting or covered with navigation symbols. • Confirm that the choice you are leaning toward is where you have actually seen edition / correction / revision dates on real charts or in textbook illustrations.
