Answer

Irrelevant
The word 'extraneous' derives from the Latin prefix 'extra-', meaning 'outside' or 'beyond'. In the context of streamlining a briefing, material that lies outside the essential scope is irrelevant.

Step-by-Step Solution

1
Analyze the prefix and morphological structure of the target word
The prefix 'extra-' means 'outside', 'beyond', or 'external to'.
Prefix identification clarifies the fundamental spatial or categorical meaning of the word.
2
Apply the prefix meaning to the sentence context
Details that are 'outside' the core mission objective are nonessential or irrelevant.
Contextual integration confirms that information removed to make a briefing concise must be irrelevant.
