Zorluk: OrtaResolving Paradoxes and Discrepancies

In 2025, a commercial fruit orchard replaced its traditional synthetic chemical pesticides with an organic biological control system that introduced beneficial predatory insects. During the subsequent harvest season, field inspections revealed that the total population of fruit-damaging pests in the orchard was 30 percent higher than in the previous year. Nevertheless, the proportion of harvested fruit that qualified for premium Grade-A market classification was significantly higher than in any preceding year.

Which of the following, if true, most helps to resolve the apparent discrepancy described above?

  1. A
    The purchasing and release costs of the predatory insects were lower than the annual expense of purchasing and spraying synthetic chemical pesticides.
  2. B
    Consumer demand for organically cultivated fruit has risen sharply, enabling orchards to sell Grade-A produce at a higher retail markup.
  3. The predatory insects specifically suppressed pest larvae that cause internal core rot, leaving pests to cause only light skin blemishes, whereas the chemical pesticides previously used routinely left chemical residue that automatically disqualified fruit from Grade-A status.Cevap
  4. D
    Pest populations in neighboring fruit orchards that continued using synthetic chemical pesticides sustained even severe crop damage due to weather conditions.
  5. E
    The total weight of all fruit harvested from the orchard was lower in 2025 than in prior years due to unseasonably late spring frosts.

Cevap

The apparent paradox is resolved by the fact that predatory insects limited pest damage to superficial surface blemishes while eliminating the chemical residues from synthetic sprays that previously triggered automatic Grade-A disqualifications.
The correct answer successfully bridges the gap between increased pest counts and higher Grade-A fruit proportions. It shows that while overall pest numbers rose, the damage caused was restricted to minor surface blemishes that did not fail Grade-A standards. Simultaneously, removing synthetic pesticides eliminated chemical residue disqualifications, boosting the net proportion of fruit achieving Grade-A status.

Adım Adım Çözüm

1
Identify the two contradictory facts in the stimulus.
Fact 1: Total population of fruit-damaging pests increased by 30%. Fact 2: The proportion of harvested fruit qualifying for premium Grade-A classification was significantly higher than in prior years.
Resolving a discrepancy requires finding an underlying cause that allows both statements to be simultaneously true.
2
Evaluate the mechanism provided by each answer choice.
The correct choice explains that predatory insects altered the nature of pest damage (shifting it from internal rot to minor cosmetic marks) while removing synthetic chemical residue, which was a major cause of Grade-A disqualification in previous years.
This dual mechanism accounts for both the survival of more pests and the increased rate of Grade-A qualification.
