01 What problem may arise if a public announcement contains too many technical terms?
Answer and explanation
Correct answer: B. General listeners may not understand the message correctly
Explanation: The governing concept is audience-centred communication. A public announcement is effective only when its intended audience can understand the vocabulary and message. Excessive technical jargon creates a language barrier, especially for listeners who do not know the specialised field. Thus, option B is correct: ordinary listeners may misunderstand or fail to understand the announcement. The other choices describe unrelated effects; technical terms do not make a message visual, automatically record it or improve voice clarity.
