Difficulty: Very hardDrawing Logical Conclusions

Under the revised Severe Atmospheric Protocol, commercial flights must either reroute to an alternate sector or engage high-altitude holding patterns if microburst activity is detected within a 20-mile radius. Rerouting is strictly prohibited if flight fuel reserves are below 45 minutes. Conversely, high-altitude holding patterns require immediate clearance from a centralized air traffic control facility. Flight 880 successfully complied with the protocol after detecting severe microburst activity 12 miles ahead of its trajectory, despite being unable to establish communication with the centralized facility.

Evaluate whether the following concluding statement is strictly true based on the passage: Flight 880 possessed fuel reserves of at least 45 minutes.

Answer: Answer

Answer

True
The statement is logically true because the deductive chain requires it. Flight 880 complied with the protocol but could not get clearance to hold, forcing it to reroute. Because it compliantly rerouted, it is a logical certainty that it possessed the requisite 45 minutes of fuel.

Step-by-Step Solution

1
Identify the mandatory conditional trigger.
Flights within 20 miles of a microburst must either reroute or enter a holding pattern.
Establishing the initial required actions for Flight 880, which detected a microburst at 12 miles.
2
Evaluate the viability of the holding pattern option.
Flight 880 could not enter a holding pattern.
Holding patterns require clearance from the centralized facility, which the flight could not communicate with.
3
Determine the necessary action taken.
Flight 880 must have rerouted.
The passage explicitly states the flight successfully complied with the protocol. With holding eliminated, rerouting was the only compliant option.
4
Extract the prerequisite constraint for the taken action.
Flight 880 must have had fuel reserves of 45 minutes or more.
The passage states rerouting is prohibited if fuel is below 45 minutes. Since they rerouted compliantly, they must have met this requirement.
