explanation: an "airplane" is where a "pilot" works, and "pilot" is a profession. a "classroom" is a place where a "teacher" works, and "teacher" is a profession. the place where the "navy" works should be the warship, not the "sea". "wife" is an identity, not a profession. "emperor" is not a profession.
