Which method enables long-distance speech communication?

• A. Telephone
• B. Verbal
• C. Presentations
• D. Written

Answer: (A)

Long-distance speech communication relies on a method that carries voice signals between distant locations. The telephone fits this role because it converts a speaker’s voice into electrical signals and transmits them over wires or wireless networks, enabling real-time conversation over long distances. Verbal describes spoken language itself rather than a transmission method, so it doesn’t specify how to reach distant listeners. Presentations are typically delivered to an in-person audience, even with aids, and aren’t primarily about enabling long-distance speech. Written communication uses text rather than voice, so it doesn’t provide spoken exchange. Therefore, the telephone is the method that enables long-distance speech communication.
