Zorluk: OrtaInference and Logical Deduction

Read the following passage carefully:

Under the 2026 Maritime Cabotage and Port Infrastructure Act, foreign-flagged cargo vessels are prohibited from transporting domestic freight directly between two coastal ports within the sovereign waters of the state unless granted an emergency waiver by the Port Regulatory Authority. Such emergency waivers are issued exclusively during declared national supply chain disruptions and require proof that no domestic-flagged vessel of equivalent cargo capacity is available within a 48-hour sailing window. Furthermore, the Act mandates that all port operators allocate at least 30 percent of their container berths to domestic feeder vessels during peak seasonal trade periods. Compliance with berth allocation is tracked via automated transponder logs, and failure to meet the threshold results in a mandatory 15 percent surcharge on all port fees levied on the non-compliant terminal operator for the subsequent quarter.

Based strictly on the passage above, which of the following statements are logically valid inferences?

  1. A foreign-flagged vessel cannot legally obtain an emergency cabotage waiver during a declared national supply chain disruption if a domestic vessel with equivalent cargo capacity is available within 24 hours.Cevap
  2. Port operators who allocate only 25 percent of their container berths to domestic feeder vessels during peak trade periods will be subject to a financial surcharge in the subsequent quarter.Cevap
  3. C
    The Port Regulatory Authority possesses discretionary power to grant cabotage waivers to foreign vessels during routine, non-emergency trade operations.
  4. D
    Automated transponder logs are deployed by port authorities primarily to measure international vessel seaworthiness and safety compliance.

Cevap

The logically valid statements are that a foreign-flagged vessel cannot obtain an emergency waiver if a domestic vessel of equivalent capacity is available within 24 hours, and that port operators allocating only 25 percent of berths to domestic feeder vessels during peak trade periods will face a financial surcharge in the following quarter.
The inference regarding the 24-hour domestic vessel availability is strictly valid because 24 hours falls within the 48-hour restriction window, preventing waiver eligibility. The inference regarding the 25 percent berth allocation is also strictly valid because 25 percent is less than the mandated 30 percent minimum, triggering the 15 percent fee surcharge penalty.

Adım Adım Çözüm

1
Analyze the conditions required for an emergency cabotage waiver.
Emergency waivers require a declared national supply chain disruption AND proof that no domestic vessel of equivalent capacity is available within 48 hours.
Evaluating the option regarding domestic vessel availability within 24 hours against the 48-hour window.
2
Deduce the consequence of having a domestic vessel available within 24 hours.
Since 24 hours is less than 48 hours, a domestic vessel is available within the restricted window, making the foreign vessel ineligible for the waiver.
Validating the logical necessity of the waiver rule.
3
Evaluate the berth allocation threshold and penalty criteria.
Port operators must allocate at least 30 percent of berths to domestic feeder vessels during peak trade periods; failure leads to a mandatory 15 percent fee surcharge in the subsequent quarter.
Testing the statement about allocating 25 percent berth capacity.
4
Deduce the result of allocating 25 percent of container berths.
Because 25 percent is less than the mandatory 30 percent, the operator fails compliance and incurs the surcharge in the subsequent quarter.
Confirming the second valid inference.
