Is it true or false that a culture realm is the smallest possible culture region?

I would say false

Explanation:

It is false that a culture realm is the smallest possible culture region.

Explanation:

Culture realm is the set of traditions and specific cultural expressions of a specific geographical area. A clear example of culture realm is with Texas and its cowboy culture, which includes the use of horses, ranchera music and typical clothing. But culture realms are not the smallest possible cultural area, since within each cultural area there may be different subgroups with dissimilar characteristics in several aspects. Again taking the case of Texas, a cultural group that lives near the Mexican border (broad Hispanic influence) is not the same as a group that lives, on the contrary, in the north of the state (here the influence is lost). Therefore, it could be said that cultural regions do not have a limit in terms of their smallness, but depend on how different cultural events unfold in each culture realm.
