Read the passage below:
In nineteenth-century historical linguistics, the formulation of Grimm’s Law established that consonant shifts in Germanic languages followed systematic patterns rather than arbitrary transformations. However, early comparative philologists often treated apparent exceptions to these sound shifts as erratic anomalies resulting from dialectal contamination. It was not until the emergence of the Neogrammarian school in the 1870s that scholars asserted the absolute exceptionlessness of sound laws, proposing that all sound changes operate with mechanical regularity unless conditioned by specific phonetic environments or interrupted by analogical leveling. Critics initially dismissed the Neogrammarian hypothesis as an overreaching dogma that reduced the organic evolution of language to rigid mechanistic determinism. Yet, subsequent investigations into Verner’s Law demonstrated that previously unexplained voiceless-to-voiced fricative shifts were not random anomalies at all, but rather precise consequences of accentual patterns in Proto-Indo-European. Consequently, far from undermining the regularist paradigm, Verner’s work validated the Neogrammarian claim that sound shifts are governed by unyielding structural constraints.
Which of the following best describes the rhetorical function of the sentence beginning with "Yet, subsequent investigations into Verner’s Law..."?
- It provides empirical evidence that resolves an apparent contradiction, thereby countering an objection to a theoretical position.Answer
- BIt introduces a definitive counterexample that forces proponents of Neogrammarian linguistics to abandon their thesis of sound law regularity.
- CIt summarizes the primary methodological claim advanced by early comparative philologists prior to the 1870s.
- DIt demonstrates that dialectal contamination was the primary mechanism behind consonant shifts in early Proto-Indo-European.
- EIt adopts an overtly hostile stance toward critics by accusing them of deliberate scholarly misinterpretation.
