Difficulty: EasyMust Be True Questions

Every commercial aircraft manufactured by AeroFlight Industries is equipped with the advanced automated navigation suite. Furthermore, no aircraft equipped with the advanced automated navigation suite requires a dedicated human navigator on board.

Based on the information above, it must be true that no commercial aircraft manufactured by AeroFlight Industries requires a dedicated human navigator on board.

Answer: Answer

Answer

True
The correct answer is True because the two premises form a perfect transitive conditional chain. 'Every A is B' combined with 'No B is C' yields the logically provable conclusion 'No A is C'. Therefore, the statement that no AeroFlight commercial aircraft require a dedicated human navigator is 100% proven from the text.

Step-by-Step Solution

1
Analyze the first premise to establish its conditional relationship.
If an aircraft is an AeroFlight commercial aircraft, then it is equipped with the advanced automated navigation suite.
Translating absolute statements ('Every...') into formal conditional logic helps identify necessary and sufficient conditions.
2
Analyze the second premise to establish its conditional relationship.
If an aircraft is equipped with the advanced automated navigation suite, then it does not require a dedicated human navigator on board.
Translating negative absolute statements ('no...') connects the sufficient condition to a negative necessary condition.
3
Combine the conditional relationships into a logical chain.
AeroFlight commercial aircraft → advanced automated navigation suite → does NOT require a dedicated human navigator.
If A implies B, and B implies C, then A implies C (the transitive property of conditionals).
4
Evaluate the statement provided at the end of the stem against the established logical chain.
The statement accurately reflects the valid deduction (AeroFlight commercial aircraft → does NOT require a dedicated human navigator).
To verify if a statement must be true, it must be directly proven by the premises without any outside assumptions.
