🔍 Key Concepts

• NGA (NIMA) Pub 117, Chapter 8 – what its wartime instructions generally cover • How merchant vessels are expected to operate when hostilities begin (routing, reporting, control) • The meaning of terms like danger zone, shipping control, and darken ship in wartime procedures

💭 Think About

• Which of these options sounds like a specific instruction that would reasonably appear in a global publication like Pub 117, rather than a very narrow or oddly limited rule? • Think about how navies typically protect merchant shipping in wartime: do they want independent action by each master, or some form of centralized coordination? • Ask yourself which choices contain absolute statements ("only," "should not") that might be too rigid for a worldwide emergency directive.

✅ Before You Answer

• Check which option involves coordinating with official control organizations versus acting entirely on your own. • Consider whether Pub 117 would likely give a blanket rule about day vs. night port entry or distance from a danger zone, or instead emphasize communication and control. • Verify which statement aligns with the general goal of organizing and managing merchant shipping safely during wartime conditions.
