🔍 Key Concepts

• National responsibility for aids to navigation (lights, buoys, fog signals) in Canadian waters • Difference between hydrographic services (charts & publications) and coast guard services (aids to navigation, SAR, etc.) • Distinguish between Canadian and U.S. authorities named in the options

💭 Think About

• First, decide whether this publication is a Canadian or U.S. document based on the title. Which options can you eliminate right away? • Think about what a hydrographic service normally produces versus what a coast guard typically manages. Which one is more directly tied to maintaining physical aids to navigation? • Ask yourself: who is operationally in charge of lights, buoys, and fog signals in Canada—the chart makers or the service that maintains aids to navigation?

✅ Before You Answer

• Eliminate any choices that clearly refer to U.S. organizations, since the title is a Canadian publication. • Recall which Canadian organization is responsible for aids to navigation rather than charting and mapping. • Before choosing, match the job: does this book list and describe physical aids (lights, buoys, fog signals) or produce nautical charts? Pick the organization whose main role best fits that job.
