Zorluk: OrtaDistinguishing Main Point from Subsidiary Points

For decades, the dominant paradigm in ecological conservation was the single-species approach, which focused resources on protecting apex predators or charismatic megafauna. This strategy was politically appealing because it offered highly measurable, immediate outcomes: a stabilized population of a specific endangered species could be easily quantified and communicated to the public. However, ecologists increasingly recognize that this approach is fundamentally inadequate in the face of rapid macro-environmental shifts. By treating ecosystems as static backgrounds rather than dynamic, interdependent networks, single-species conservation often fails to protect the underlying processes that sustain biodiversity. For instance, successfully stabilizing a specific avian population in a localized forest tract does little to ensure the ecosystem's survival if shifting wildfire regimes—a macro-level threat—fundamentally alter the forest's composition. Consequently, conservation biology has begun pivoting toward a landscape-level resilience model, which prioritizes the functional integrity of entire ecosystems over the survival of isolated species. While critics rightly point out that this holistic approach is bureaucratically cumbersome and lacks the immediate, headline-grabbing successes of the older model, such administrative difficulties are a necessary trade-off. Ultimately, because isolated conservation efforts are easily undone by systemic ecological collapse, embracing the complexity of landscape-level management represents the only viable path to securing long-term environmental stability.

Which of the following most accurately expresses the main point of the passage?

  1. A
    The single-species approach to conservation was politically advantageous because it generated highly quantifiable results that could be easily communicated to the public.
  2. Although the landscape-level resilience model presents administrative difficulties, it must replace the historically dominant single-species approach because only the former can secure long-term ecological stability.Cevap
  3. C
    Because ecosystems are dynamic networks, protecting an isolated species in a localized area cannot prevent ecological collapse caused by macro-environmental threats.
  4. D
    Global environmental stability can only be achieved if conservationists completely abandon the protection of charismatic megafauna and focus entirely on bureaucratic landscape management.
  5. E
    A discussion of the historical shift in ecological conservation from a paradigm focused on isolated species to one focused on the functional integrity of entire ecosystems.

Cevap

The correct answer states that despite its bureaucratic drawbacks, the landscape-level resilience model is a necessary replacement for the single-species approach in order to ensure long-term environmental stability.
The correct answer perfectly encapsulates the author's primary argument. It acknowledges the shift from the old model to the new model, incorporates the author's concession that the new model is administratively difficult, and delivers the final judgment that this shift is imperative for long-term ecological stability.

Adım Adım Çözüm

1
Analyze the passage's structure to identify the author's primary argument.
The author introduces an old model (single-species), critiques its ecological flaws, introduces a new model (landscape-level), concedes its administrative flaws, and concludes that the new model is nevertheless necessary.
Understanding the structural flow helps separate the background context and supporting evidence from the final, synthesized conclusion.
2
Differentiate between supporting evidence (subsidiary points) and the overarching conclusion.
The political appeal of the old model and the specific example of the avian population are premises building toward the final sentence, which serves as the ultimate thesis.
Main point questions require selecting the answer that encompasses the entire argument, not just a factual sub-component.
3
Evaluate the options to find the one that synthesizes the entire argument.
The correct option captures the transition between the two models, the author's concession regarding bureaucracy, and the final judgment regarding necessity.
A complete main point must reflect the author's specific stance and the scope of the passage's conclusion.
