01 Why should unnecessary difficult words be avoided while speaking?
Answer and explanation
Correct answer: D. They can make the message difficult to understand
Explanation: The governing concept is clarity in verbal communication. Unfamiliar or unnecessarily difficult words may prevent a listener from understanding the intended meaning, especially when the listener has limited subject knowledge. Therefore, simple, familiar, context-appropriate words are preferable. Option D is correct; the other choices describe effects that are false or not generally applicable.
