Zorluk: ZorRhetorical Structure and Sentence Function

Read the passage below. Identify which sentence functions as a concession that acknowledges a methodological limitation of the primary comparative framework under discussion.

Cevap:[Sentence 1] In palaeoclimatology, the mid-Pliocene Warm Period is frequently analyzed as an analog for projected global warming scenarios because atmospheric carbon dioxide concentrations were comparable to contemporary levels. [Sentence 2] Proponents of this comparative framework argue that sea surface temperature anomalies during the Pliocene offer valuable insight into equilibrium climate sensitivity under sustained greenhouse forcing. [Sentence 3] Admittedly, disparities in ancient continental topography and polar ice sheet extent preclude an exact equivalence between Pliocene climate dynamics and modern anthropogenic warming trajectories. [Sentence 4] Nevertheless, evaluating Pliocene ocean circulation patterns yields essential empirical benchmarks for refining long-term climate models.

Sentence that serves as the concession: 【Sentence 3】

Cevap

Sentence 3 functions as a concession because it introduces a countervailing fact—disparities in topography and ice sheet extent—that limits the direct applicability of the mid-Pliocene comparative framework.
Sentence 3 is the correct response because it uses the structural transition word 'Admittedly' to acknowledge a specific limitation—namely, that geographical and cryospheric differences between the Pliocene epoch and the present prevent a direct, one-to-one comparison.

Adım Adım Çözüm

1
Analyze the rhetorical movement of the passage across all four sentences.
Sentence 1 introduces the main analog model, Sentence 2 supports its utility, Sentence 3 introduces a qualifying constraint, and Sentence 4 reasserts its overall value despite that constraint.
Tracking structural transitions allows identification of where the author shifts from supporting a framework to qualifying it.
2
Locate explicit discourse markers signaling a concession or qualification.
The word 'Admittedly' at the start of Sentence 3 explicitly signals an admission of a counter-fact or limitation.
Transition signals like 'admittedly,' 'granted,' or 'to be sure' introduce rhetorical concessions.
3
Confirm the functional scope of the identified sentence.
Sentence 3 highlights specific physical differences (topography and ice sheets) that prevent exact equivalence between past and present climate dynamics, directly conceding a methodological constraint.
Verifying that the content matches the definition of a concession ensures accurate selection.
