Question

complete the analogy.
doctor is to stethoscope as navigator is to
ship
discovery
compass

Explanation:

To solve the analogy, we analyze the relationship between "doctor" and "stethoscope": a stethoscope is a tool used by a doctor. Now, we check the options for "navigator": a compass is a tool used by a navigator. "Ship" is the vehicle a navigator works on, and "discovery" is an outcome, not a tool. So the correct tool - user relationship is navigator - compass.

Answer:

compass
