What are the two most common causes of communications problems?

The correct choice highlights that low batteries and difficult terrain are indeed prevalent causes of communication problems in Search and Rescue operations.

Low battery levels can severely hinder communication devices, rendering them ineffective when they are needed most. Search and Rescue teams rely heavily on communication tools such as radios and mobile devices, which require adequate power to function. If batteries are not charged or are running low, important messages may not be conveyed, leading to potential safety risks for both rescuers and those in need of assistance.

Difficult terrain poses another significant challenge. Rugged landscapes, mountains, dense forests, or canyons can disrupt radio signals and make it challenging to maintain reliable communication. Even if a device is fully functioning and powered, the physical environment can obstruct signals and affect the overall effectiveness of communication efforts.

Together, low batteries and difficult terrain encapsulate two of the most common obstacles that can impair communication during critical Search and Rescue missions.
