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.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
