Zorluk: KolayResolve the Paradox

An organic apple orchard introduced a new mineral-based spray specifically designed to repel codling moths, a primary pest responsible for damaging apple crops. Although the spray successfully eliminated nearly all codling moths from the orchard within weeks, the percentage of harvested apples showing pest damage was significantly higher at the end of the season than in previous years.

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

  1. A
    The mineral spray cost significantly more per acre to apply than conventional chemical pesticides previously used in the region.
  2. B
    Codling moths have historically caused more total crop loss in apple orchards across the state than any other insect species.
  3. Codling moths naturally compete with and suppress populations of leafroller caterpillars, a pest unaffected by the spray that damages apples even more aggressively.Cevap
  4. D
    The spray leaves a harmless white residue on apple skins that can be completely removed only through thorough washing after harvest.
  5. E
    Insects rarely develop physiological resistance to mineral-based repellents as quickly as they do to synthetic chemical compounds.

Cevap

The statement showing that codling moths naturally suppress populations of leafroller caterpillars, a pest unaffected by the spray that damages apples even more aggressively.
The correct response demonstrates that the removal of codling moths removed natural competition for leafroller caterpillars. Because leafrollers are unaffected by the spray and damage apples more severely, their population surge explains why overall crop damage rose despite the successful elimination of the primary target pest.

Adım Adım Çözüm

1
Identify the two competing facts in the stimulus.
Fact 1: The spray effectively eliminated nearly all codling moths. Fact 2: Overall pest damage on harvested apples increased significantly.
Resolving a paradox requires clearly defining the exact tension that must be reconciled.
2
Determine the necessary bridging mechanism.
An explanation showing how eliminating codling moths could inadvertently increase total pest damage.
A valid resolution must allow both stated facts to be simultaneously true without denying either premise.
3
Evaluate the answer choices to locate the causal link.
The choice identifying an unaffected competitor pest that causes even greater damage when freed from codling moth competition reconciles both facts.
This shows a direct secondary consequence of the spray that accounts for the higher total damage.
