Choose the pair that best represents a similar relationship to the one expressed in the original pair of words. AERIE : EAGLE

capital : government
bridge : architect
unit : apartment
kennel : veterinarian E. house : person

The correct answer is: AERIE : EAGLE :: DEN : BEAR.

An aerie is a nest built by an eagle, while a den is a home built by a bear. Both aeries and dens are typically located in high places, and they provide shelter and protection for their inhabitants.

The other options do not represent a similar relationship. A capital is the seat of government, not a type of government. A bridge is a structure that spans a river or other obstacle, not a type of architect. A unit is a single thing or person, not a type of apartment. A kennel is a place where dogs are kept, not a type of veterinarian. A house is a building for human habitation, not a type of person.
