Zorluk: OrtaFunction of Specific Details

Consider the following passage discussing Pleistocene ecology:

The Pleistocene megafaunal extinction has traditionally been attributed to rapidly shifting climatic conditions at the end of the last ice age. However, proponents of the 'overkill hypothesis' argue that human predation was the primary driver of this ecological collapse. To counter the climate-driven model, these proponents point out that many megafaunal species had successfully navigated equally severe glacial-interglacial transitions in previous epochs without experiencing mass extinctions. Furthermore, the survival of dwarfed mammoth populations on Wrangel Island until roughly 4,000 years ago—long after the global climate had stabilized, but exactly when human hunter-gatherers first arrived on the island—is frequently cited by overkill proponents. If climate were the sole culprit, they argue, these isolated populations should have perished concurrently with their mainland counterparts, regardless of their insular environment.

The author mentions the 'survival of dwarfed mammoth populations on Wrangel Island' primarily in order to...

  1. A
    highlight a unique environmental anomaly that explains how certain species survived previous glacial-interglacial transitions.
  2. B
    illustrate a phenomenon that advocates of the climate-driven hypothesis use to explain the gradual nature of the extinction.
  3. C
    prove that isolated ecosystems are fundamentally immune to the severe climatic shifts that affect mainland environments.
  4. present a specific piece of evidence that challenges the adequacy of the traditionally accepted explanation for a historical phenomenon.Cevap
  5. E
    suggest that human hunter-gatherers systematically targeted island ecosystems after mainland resources had been depleted.

Cevap

The correct answer is the option stating that the reference presents a specific piece of evidence that challenges the adequacy of the traditionally accepted explanation for a historical phenomenon.
The correct answer accurately synthesizes the rhetorical structure of the passage. The 'traditionally accepted explanation' is the climate-driven model. The 'survival of dwarfed mammoth populations' is introduced by proponents of the overkill hypothesis to show that megafauna survived changing climates when humans were absent, thereby directly challenging the adequacy of that traditional climate explanation.

Adım Adım Çözüm

1
Identify the primary topic and the opposing viewpoints in the passage.
The passage discusses the Pleistocene megafaunal extinction, contrasting the traditional 'climate-driven' model with the newer 'overkill hypothesis' (human predation).
Understanding the core argument is necessary to determine the structural function of any specific detail within that argument.
2
Locate the specific detail in the text and identify who is bringing it up.
The text states that the survival of Wrangel Island mammoths 'is frequently cited by overkill proponents.'
Attributing the evidence to the correct viewpoint prevents viewpoint misattribution errors.
3
Determine how this specific group uses the detail to advance their overall argument.
The overkill proponents use this detail to show that mammoths survived climate stabilization but went extinct exactly when humans arrived, implying climate was not 'the sole culprit.'
This reveals the rhetorical purpose: it serves as a counterexample intended to cast doubt on the opposing, traditional theory.
