Analogy — Traveller : Journey :: Sailor : ? Select the term that names the typical expedition or travel undertaken by a sailor, paralleling traveller–journey.

Introduction / Context:
“Traveller : Journey” links an agent with the activity undertaken. The parallel for a sailor is the term that denotes the travel/expedition by sea. This is a standard agent–activity pairing in vocabulary questions.

Given Data / Assumptions:

• Traveller → journey (activity).
• Sailor → voyage (sea journey/activity).
• Eliminate medium (“water”), vehicle (“ship”), or group (“crew”) since the analogy calls for activity.

Concept / Approach:
Maintain category alignment: both right-hand terms should be activities, not objects or collectives. “Voyage” is the natural activity noun for a sailor’s travel by sea.

Step-by-Step Solution:

Verification / Alternative check:
Usage in literature and common speech consistently pairs “sailor” with “voyage.”

Why Other Options Are Wrong:

• Water — medium, not an activity.
• Ship — vehicle, not an activity.
• Crew — group of people, not an activity.

Common Pitfalls:
Picking a closely related noun (ship) instead of the activity noun demanded by the analogy.

Final Answer:
Voyage
