Step 1: Understanding the Concept:
The question asks to identify the incorrect statement among the given options about the qualities of a good communicator and their relation to teaching.
Step 2: Detailed Explanation:
- Statements A, B, and C describe positive attributes that contribute to effective communication. A good sense of humour can make communication more engaging, wide reading knowledge provides depth and context, and command over language is fundamental for clarity and precision. These are all plausible characteristics of a good communicator.
- Statement D claims that a good communicator cannot be a good teacher. This is a strong, negative, and absolute statement. Effective communication is one of the most essential skills for a teacher. A teacher needs to clearly explain complex concepts, engage students, provide feedback, and create a positive learning environment, all of which rely heavily on good communication skills. Therefore, being a good communicator is a prerequisite for being a good teacher, not a barrier. The statement is logically false.
Step 3: Final Answer:
The statement "A good communicator cannot be a good teacher" is not correct.
