Zorluk: OrtaPassage Assumptions and Underlying Premises

Read the following passage carefully and answer the question that follows:

To mitigate agricultural soil degradation and encourage sustainable land use, several state governments have launched Payments for Ecosystem Services (PES) schemes that provide direct financial compensation to smallholder farmers who plant native trees within their crop landscapes. Proponents argue that compensating farmers for the ecological benefits and carbon sequestered by these trees will offset initial yield losses incurred during the transition away from intensive monoculture farming, thereby ensuring sustained long-term adoption. However, critics point out that carbon measurement on fragmented agricultural holdings remains technically complex and expensive to monitor. Consequently, unless state agencies establish long-term institutional mechanisms for guaranteed carbon credit off-take at predictable floor prices, smallholder farmers will revert to high-input monoculture once the initial financial incentives expire after five years.

Which of the following is a crucial underlying assumption required for the author's conclusion regarding the reversion to monoculture farming to hold true?

  1. A
    Without guaranteed carbon credit purchase prices, smallholder farmers will inevitably revert to high-input monoculture once the initial state subsidy expires.
  2. Smallholder farmers' long-term decision to maintain agroforestry practices is primarily governed by financial return rather than non-monetary motivations.Cevap
  3. C
    Agroforestry carbon sequestration is scientifically proven to reduce global atmospheric carbon more effectively than industrial carbon capture technologies.
  4. D
    Smallholder farmers can avoid initial crop yield losses during the transition period by utilizing native tree varieties.

Cevap

The correct underlying assumption is that smallholder farmers' long-term decision to maintain agroforestry practices is primarily governed by financial return rather than non-monetary motivations.
The author's conclusion asserts that a lack of financial price guarantees after five years will cause smallholder farmers to return to monoculture. For this claim to be valid, the author must implicitly assume that economic viability is the essential deciding factor for farmers. If farmers were guided by non-financial incentives (e.g., environmental stewardship independent of income), the absence of long-term financial guarantees would not automatically force a reversion to monoculture.

Adım Adım Çözüm

1
Identify the author's main argument and conclusion in the passage.
The author concludes that farmers will revert to monoculture farming after the five-year subsidy ends unless long-term guaranteed carbon credit prices are established.
An assumption is an unstated link connecting the evidence (end of subsidies/lack of price guarantees) to the conclusion (farmers will revert to monoculture).
2
Apply the Negation Test to candidate premises.
Negate the statement: 'Farmers are NOT primarily motivated by financial return.' If non-monetary factors motivate them, they would continue agroforestry even without financial guarantees, which causes the author's argument to collapse.
A valid assumption must be logically necessary for the conclusion to hold.
