Greenbergian universals are induced from empirical samples, whereas Chomskyan universals are posited as innate mental constraints. What does this distinction imply when a newly documented language violates an absolute universal?

C. A Greenbergian rule is immediately refuted whilst a Chomskyan principle can survive

Because taxonomic universals are empirical claims across attested speech, one exception disproves an absolute rule. Conversely, innate generative constraints may remain theoretically viable by attributing surface violations to language-specific parameters or performance factors rather than immediate refutation.
