Zorluk: OrtaPoints of Disagreement

Passage A
The sudden disappearance of megafauna in North America at the end of the Pleistocene epoch closely coincides with the arrival of the Clovis people. The "overkill" hypothesis posits that these early humans, armed with advanced projectile points, hunted these large, ecologically naive mammals to extinction. Critics point to climate change as an alternative explanation, but this is unconvincing. Earth had experienced numerous severe glacial-interglacial climate shifts prior to this period without triggering mass extinctions. The unique variable at the end of the Pleistocene was not a warming climate, but the introduction of a highly effective apex predator.

Passage B
Attributing the late Pleistocene megafaunal extinction primarily to human hunting significantly overestimates the demographic and technological capacity of early Americans. It is highly improbable that small, highly mobile bands of hunter-gatherers could systematically exterminate dozens of wide-ranging species across an entire continent. Instead, the dramatic climate warming at the end of the last Ice Age fundamentally reorganized ecosystems, replacing expansive nutrient-rich steppes with habitats unable to support megaherbivores. While humans certainly hunted megafauna, their impact was secondary; they merely provided the final push to populations already doomed by severe habitat fragmentation and loss of food resources.

Which one of the following most accurately describes a point of disagreement between the authors of Passage A and Passage B?

  1. Whether early human populations possessed the demographic and technological capacity to primarily cause the continental extinction of megafauna.Cevap
  2. B
    Whether severe glacial-interglacial climate shifts had occurred on Earth prior to the end of the Pleistocene epoch.
  3. C
    Whether early humans actually engaged in the hunting of large North American mammals during the late Pleistocene.
  4. D
    Whether environmental transformations inevitably result in the total extinction of megaherbivore populations.
  5. E
    Whether the arrival of early human populations caused the severe habitat fragmentation that led to the decline of the megafauna.

Cevap

The authors disagree on whether early human populations possessed the demographic and technological capacity to primarily cause the continental extinction of megafauna.
Passage A claims that early humans were a highly effective apex predator capable of hunting the megafauna to extinction, acting as the 'unique variable' that caused the event. Passage B directly contradicts this, stating that it is 'highly improbable' that these human populations could systematically exterminate species across a continent, arguing that attributing the extinction to them 'significantly overestimates' their capacity. Therefore, they clearly disagree on the capability of humans to cause the extinction.

Adım Adım Çözüm

1
Analyze Passage A to determine the author's central claim regarding the cause of the megafaunal extinction.
Passage A argues that humans were a 'highly effective apex predator' and the 'unique variable' that hunted the megafauna to extinction, dismissing climate change as the primary cause.
Identifying the first author's stance on the core topic is necessary to establish one side of the potential disagreement.
2
Analyze Passage B to determine its central claim and locate where it intersects with Passage A.
Passage B argues that attributing the extinction primarily to humans 'overestimates their demographic and technological capacity,' asserting that climate-induced habitat loss was the primary cause and humans were only a secondary factor.
Finding the second author's stance on the exact same topic reveals where the two arguments collide.
3
Synthesize the overlapping views to formulate the precise point of mutual disagreement.
The exact point of friction is the extent of human capability: Passage A affirms they were capable of causing the extinction, while Passage B denies they had the capacity to do so systematically.
A valid point of disagreement requires one author to answer 'yes' to a proposition while the other author answers 'no'.
4
Evaluate the answer choices to find the one that accurately reflects this synthesis while eliminating choices based on false disagreements or shared views.
The correct option correctly captures the conflict over human demographic and technological capacity. The other choices involve shared agreements (humans hunted animals), unaddressed topics (previous climate shifts), or extreme distortions ('inevitably').
Distractors in comparative reading often rely on statements that only one author addresses, or facts that both authors actually agree upon.
