Question ID:PT88 S2 Q18 Passage:Anthropologists have long debated whether the customs of a culture invariably function to preserve it.

If this definition is correct, then the customs of a culture necessarily function to preserve it, even if only in the most trivial sense, because, under this conception of a culture, the abandonment of any custom by a culture's members would by definition constitute that culture's destruction.
