Which skill is enhanced by practicing extemporaneous speaking?

Practicing extemporaneous speaking significantly enhances critical thinking and adaptability because it requires speakers to think on their feet and respond spontaneously to topics or questions. This type of speaking involves formulating responses quickly, which fosters an ability to analyze information, construct coherent arguments, and adjust one's speech based on audience reactions or the flow of conversation.

Moreover, since the speaker does not have a detailed script to rely on, they must draw on their knowledge, experience, and quick judgment to make their points clear and persuasive. This practice not only sharpens the ability to articulate thoughts clearly but also enhances the skill of adapting to new information or unexpected developments during the discussion, which is vital in effective communication and leadership.

While other options such as writing skills, memorization skills, and visual design skills may be useful in various contexts, they do not have the same direct relationship with the dynamic and immediate verbal interactions that extemporaneous speaking entails.
