Difficulty: Very hardMain Idea and Central Theme Identification

Read the passage carefully and answer the question that follows:

The emerging bio-technological paradigm of de-extinction—utilizing CRISPR-based gene editing and somatic cell nuclear transfer to resurrect proxy versions of extinct organisms—is increasingly promoted by advocates as a transformative frontier in conservation genetics. However, this techno-centric enthusiasm threatens to displace the foundational principles of modern biodiversity stewardship. Attempting to reintroduce functional proxies of long-extinct species into contemporary ecosystems overlooks the critical reality that habitat fragmentation, anthropogenic climate disruption, and invasive species dynamics remain the paramount drivers of modern ecological collapse. Reintroduced proxies would inevitably enter severely degraded biomes incapable of supporting their historical ecological roles, rendering such interventions ecologically nominal at best.

Furthermore, directing vast financial capital and institutional bandwidth toward high-profile de-extinction initiatives creates a severe resource asymmetry. It diverts finite conservation funding away from baseline habitat preservation, indigenous community-led stewardship, and the immediate protection of critically endangered extant species currently on the brink of extinction. While resurrection biology may yield speculative advancements in genomic manipulation, framing it as a panacea for global biodiversity loss represents a dangerous technological solutionism. True ecological resilience cannot be engineered through isolated genetic resurrection; it requires preserving the holistic integrity of living ecosystems and addressing the systemic socio-economic drivers of environmental degradation.

Which of the following statements correctly capture the core thesis and central argument advanced by the author in the passage?

  1. De-extinction initiatives risk misallocating finite financial resources and institutional focus away from the urgent protection of extant species and baseline habitat preservation.Answer
  2. B
    Resurrection biology possesses no scientific value whatsoever and should be strictly prohibited across all research institutions.
  3. Relying on technological interventions like species resurrection fails to resolve the systemic environmental drivers causing contemporary ecological collapse.Answer
  4. D
    CRISPR-based cloning technologies have proven commercially unviable due to the inability to recover intact genomic material from fossilized remains.

Answer

The core thesis is correctly captured by the statements highlighting that de-extinction initiatives risk misallocating finite resources away from existing species preservation, and that relying on technological fixes fails to address systemic drivers of ecological degradation.
The author's central thesis asserts that de-extinction embodies a flawed 'technological solutionism' that ignores the root causes of ecological degradation (such as habitat loss and climate change) while simultaneously siphoning critical funding and institutional resources away from saving extant endangered species and preserving living habitats. The two correct statements accurately summarize these central pillars of the argument.

Step-by-Step Solution

1
Analyze the main argument and paragraph structure
The first paragraph establishes that reintroducing extinct proxy species fails to fix underlying drivers of ecosystem collapse (habitat fragmentation, climate change). The second paragraph argues that funding de-extinction creates resource asymmetry, diverting money from protecting living species.
Identifying the macro-structure helps isolate the author's primary thesis from secondary nuances.
2
Evaluate candidate summary statements against passage claims
The statement regarding resource misallocation directly aligns with paragraph two's point about resource asymmetry. The statement regarding technological fixes failing to solve systemic environmental drivers directly aligns with the critique of technological solutionism.
Valid central theme statements must synthesize the core thesis without bringing in unsupported facts or extreme exaggerations.
3
Eliminate misrepresentative and external distractors
The claim calling for a complete ban ignores the author's nuanced admission of genomic benefits. The claim about CRISPR commercial unviability relies on external knowledge not present in the text.
Distractors often rely on tone overgeneralization or external knowledge contamination.
