Zorluk: OrtaContrast and Reversal Clues

Although the fossil records of early hominins in Eastern Africa were long considered remarkably ________, exhibiting minimal variation across distinct geographical zones, recent biomechanical re-evaluations of limb bone density suggest that local micro-environments actually fostered significant morphological divergence.

Which of the following words best completes the blank in the sentence?

  1. homogeneousCevap
  2. B
    heterogeneous
  3. C
    fragmented
  4. D
    rudimentary
  5. E
    anomalous

Cevap

The word 'homogeneous' correctly completes the sentence by establishing a contrast between uniform early hominin remains and recent findings of morphological divergence.
The sentence begins with the concessionary pivot 'Although', signaling a contrast between the historical view of hominin fossils and recent re-evaluations. The second clause reveals that recent findings show 'significant morphological divergence'. Therefore, the initial view must have been that the fossils were uniform. The option 'homogeneous' (meaning uniform or composed of similar parts) fits both the contrast with 'divergence' and the descriptive clue 'exhibiting minimal variation'.

Adım Adım Çözüm

1
Identify the structural transition word in the sentence stem.
The word 'Although' at the beginning of the sentence functions as a contrast pivot.
Contrast signals indicate that the two main clauses will express opposing or contradictory ideas.
2
Analyze the context clues in both clauses to determine target semantic valence.
The second clause notes 'significant morphological divergence', while the first clause includes the restatement clue 'exhibiting minimal variation'.
The blank must describe a state of uniformity/sameness to contrast with 'divergence' across the pivot.
3
Evaluate the answer choices against the required definition of uniform or unvarying.
'Homogeneous' directly means uniform in structure or composition, satisfying both the local clue 'minimal variation' and the macro-contrast with 'divergence'.
Only 'homogeneous' provides the exact semantic reversal demanded by the sentence structure.
