Zorluk: OrtaCentral Ideas

For years, ecologists studied urban parks primarily as isolated green patches with minimal ecological value compared to undisturbed rural forests. However, recent research by Dr. Elena Vasquez demonstrates that these urban spaces function as vital stepping-stone habitats, facilitating the movement of migratory bird species through fragmented landscapes. By tracking bird flight paths across major metropolitan areas, Vasquez's team revealed that even small, highly manicured municipal parks significantly reduce the energy expenditure of migrating species by providing crucial foraging sites. Consequently, conservation strategies must expand beyond preserving contiguous wilderness to integrate the ecological management of fragmented urban ecosystems.

Which choice best states the main idea of the text?

  1. Municipal parks, despite their small size, serve as essential stepping-stone habitats for migrating birds and should be included in broader conservation efforts.Cevap
  2. B
    Ecological conservation strategies are shifting their focus entirely from natural wilderness areas to urban green spaces.
  3. C
    Migrating birds have adapted to urban sprawl by changing their ancestral flight paths to target municipal foraging sites.
  4. D
    Small, manicured municipal parks offer more abundant food sources for migrating birds than undisturbed rural forests do.

Cevap

Municipal parks, despite their small size, serve as essential stepping-stone habitats for migrating birds and should be included in broader conservation efforts.
The correct answer accurately states that urban parks function as crucial stepping-stone habitats by providing food and resting spots for migrating birds, meaning they must be managed as part of comprehensive conservation strategies. This perfectly summarizes both the scientific finding and the conservation recommendation in the passage.

Adım Adım Çözüm

1
Analyze the text for key arguments and findings.
The text presents a contrast between the old view of urban parks (isolated, low value) and new findings (vital stepping-stone habitats for migratory birds that reduce their energy expenditure).
Identifying the shift in scientific consensus helps locate the author's primary argument.
2
Identify the conclusion or recommendation in the passage.
The text concludes that conservation strategies must expand to integrate the ecological management of fragmented urban ecosystems.
The final sentence of the passage provides the key takeaway, connecting the research on migratory birds to a broader conservation goal.
3
Evaluate the answer choices against the main finding and conclusion.
The statement summarizing the stepping-stone role of small parks and the need to include them in conservation planning is the only one that matches the passage without overgeneralizing or speculating.
Ensuring the selected choice captures both the biological function and the policy recommendation of the passage leads directly to the correct central idea.
