What is a significant benefit of using a telephone in situations like natural disasters?

Using a telephone, particularly traditional landline telephones, during situations like natural disasters offers the significant benefit of not requiring a power connection. This is crucial because during emergencies, power outages are common, disrupting electric-based communication devices such as mobile phones and computers. Traditional landline phones typically rely on the phone lines, which can still function even if the power is out, allowing individuals to communicate and access emergency services when other means may fail. This capability makes telephones particularly valuable in crisis communication where maintaining contact can be vital for safety and coordination of response efforts.

In contrast, other options highlight limitations or drawbacks rather than advantages. For example, needing a constant power supply hinders communication during outages; limited mobility restricts users’ ability to move freely while communicating; and requiring expertise for installation can delay emergency response efforts, making these attributes less beneficial in urgent situations.
