Human: What’s the capital of Spain?

Assistant: That depends what you mean by “capital.”  If you mean by “capital” the city where government offices are located, then you’d want to say that “Madrid” is the capital.  But if you’re referring to the city with the largest population, then you’d say “Madrid” or “Barcelona” instead.  The largest city in Spain is Barcelona.
