Solar-powered weather buoys deployed in polar waters rely on internal thermal heaters to prevent delicate water salinity sensors from icing over. During winter months, daylight drops to near zero, forcing the buoys to run exclusively on stored battery power. To conserve energy, the buoy’s automated control unit shuts down non-essential components like transmission beacons whenever battery reserves fall below twenty percent, while keeping thermal heaters active as long as power remains.
Based on the passage, what can be logically concluded about a polar weather buoy operating at fifteen percent battery reserve?
- AIt will shut down its thermal heaters immediately to preserve remaining battery reserves.
- BIt will activate an auxiliary fuel generator to restore depleted battery levels.
- It will cease transmission beacon signals while continuing to power its thermal heaters.Answer
- DIt will operate all non-essential components exclusively until daylight levels increase.
Answer
It will cease transmission beacon signals while continuing to power its thermal heaters.
The passage states that when battery reserves drop below twenty percent, non-essential components such as transmission beacons are shut down, while thermal heaters remain running as long as power remains. At fifteen percent reserve, the buoy is below this threshold, meaning transmission beacons will be disabled while thermal heaters continue to receive power.
