As far as I know, Russian doesn’t use the auxillary verb “do/does”.
In many languages, the “do” is often a included in the case itself, meaning that it will be part of the word “mean”, as also suggested by the usage of “means” instead of “does mean”.
I suppose another construction could be “It means what?”

In my experience, the entire continent have nuclear families except for parts of Italy and Greece.
