Zorluk: ZorConditional Logic and Formal Deductions

A marine conservation agency abides by the following guidelines regarding commercial oceanic operations: An oceanic research institute will approve a coastal zone for deep-sea mining only if the zone undergoes an ecological impact assessment. An ecological impact assessment is conducted whenever a designated marine habitat contains endangered coral species, unless the habitat is classified as a protected sanctuary. Furthermore, any coastal zone that undergoes an ecological impact assessment requires the implementation of continuous acoustic monitoring.

If the statements above are true, which of the following MUST also be true?

  1. A coastal zone cannot be approved for deep-sea mining without the implementation of continuous acoustic monitoring.Cevap
  2. B
    Any coastal zone in which continuous acoustic monitoring is implemented will automatically be approved for deep-sea mining.
  3. C
    If a designated marine habitat is classified as a protected sanctuary, an ecological impact assessment cannot be conducted under any circumstances.
  4. D
    Any designated marine habitat that contains endangered coral species must implement continuous acoustic monitoring.
  5. E
    A coastal zone that does not contain endangered coral species is not required to implement continuous acoustic monitoring under any circumstances.

Cevap

A coastal zone cannot be approved for deep-sea mining without the implementation of continuous acoustic monitoring.
The passage establishes a chain of necessary conditions: approval for deep-sea mining requires an ecological impact assessment (Approval -> Assessment), and an ecological impact assessment requires continuous acoustic monitoring (Assessment -> Monitoring). Combining these transitive statements yields Approval -> Monitoring. The contrapositive of this deduction is that without continuous acoustic monitoring, a zone cannot receive approval for deep-sea mining.

Adım Adım Çözüm

1
Formalize the conditional statements provided in the passage.
Statement 1: Approval -> Assessment. Statement 2: Coral AND NOT Sanctuary -> Assessment. Statement 3: Assessment -> Monitoring.
Mapping the premises into logical notation clarifies valid deductions and prevents common fallacies.
2
Chain the conditional statements linking Approval, Assessment, and Monitoring.
Approval -> Assessment -> Monitoring. Thus, Approval -> Monitoring.
Transitive logic allows combining two nested conditional rules sharing a middle term (Assessment).
3
Take the contrapositive of the combined deduction.
NOT Monitoring -> NOT Approval.
A conditional statement is logically equivalent to its contrapositive, confirming that without monitoring, approval is impossible.
