Zorluk: OrtaPredicting Future Outcomes

To prevent uncontrolled wildfires, a forestry management crew conducts prescribed burns only under strict environmental thresholds. Protocol mandates that if ambient relative humidity drops below 25% or sustained wind speeds exceed 15 miles per hour, all active ignition must immediately cease and ground personnel must transition to wetting down the containment perimeter. During a scheduled maintenance burn on Tuesday afternoon, field sensors record humidity falling steadily from 31% to 21%, while wind speeds remain steady at 7 miles per hour.

Based on this information, what action will the forestry crew most likely take next?

  1. A
    Continue the scheduled burn because wind speeds remain well below the maximum safety threshold.
  2. B
    Accelerate ignition across remaining sectors to finish the burn before conditions deteriorate further.
  3. Halt active burning operations and begin wetting down the containment perimeter.Cevap
  4. D
    Evacuate all personnel from the forest district due to an uncontrollable wildfire.

Cevap

Halt active burning operations and begin wetting down the containment perimeter.
The passage establishes an 'either/or' safety condition: burning must halt if humidity falls below 25% or winds exceed 15 mph. Since the humidity dropped to 21%, the crew must follow the stated protocol by halting ignition and wetting down the containment perimeter.

Adım Adım Çözüm

1
Identify the conditions that mandate a change in procedure.
The protocol states that operations must alter if relative humidity drops below 25% OR sustained winds exceed 15 mph.
Establishing the operational rule determines what environmental triggers require crew action.
2
Evaluate the current environmental data against the protocol conditions.
Relative humidity is at 21% (which is below the 25% limit), satisfying the condition for halting the burn despite wind speeds being acceptable at 7 mph.
The rule uses an 'or' condition, meaning either trigger independently requires protocol activation.
3
Determine the required protocol response.
The crew must cease active ignition and wet down the containment perimeter.
This directly matches the mandated operational procedure stated in the passage.
