Difficulty: MediumIdentifying Must-Be-True Statements and Valid Deductions

Under the guidelines of the Global Logistics Safety Board, any cargo vessel operating along Route K that carries hazardous liquid chemicals must be equipped with an automated leak-detection telemetry system. Furthermore, any cargo vessel equipped with an automated leak-detection telemetry system is subject to mandatory unannounced monthly inspections by maritime safety authorities. During the previous calendar year, the commercial vessel Vanguard operated along Route K and carried hazardous liquid chemicals.

Based on the information provided above, evaluate the truth value of the following statement: The Vanguard was subject to mandatory unannounced monthly inspections by maritime safety authorities.

Answer: Answer

Answer

The statement is True.
Combining the premises yields a valid chain of logic: (Route K + Hazardous Chemicals) → Leak-Detection Telemetry System → Mandatory Unannounced Monthly Inspections. Since the Vanguard satisfies the initial conditions, the final outcome must logically hold true.

Step-by-Step Solution

1
Identify the initial factual premises regarding the specific vessel.
The vessel Vanguard operated on Route K and carried hazardous liquid chemicals.
This establishes the antecedent conditions for the first rule.
2
Apply the first conditional rule to the established premises.
The Vanguard was required to be equipped with an automated leak-detection telemetry system.
Rule 1 dictates that operating on Route K with hazardous liquid chemicals necessitates the leak-detection system.
3
Apply the second conditional rule to the result from Step 2.
The Vanguard was subject to mandatory unannounced monthly inspections by maritime safety authorities.
Rule 2 dictates that any vessel equipped with the leak-detection telemetry system is subject to these inspections.
