Final answer:
Leading questions are not the best type of questions for effective listening; open-ended and neutral questions are preferred as they encourage genuine responses.
Step-by-step explanation:
The statement that leading questions are the best kind of questions to ask speakers as a part of an effective listening plan is false. Leading questions are designed to guide respondents towards a specific answer, which may not reflect their true opinions or knowledge. Instead, open-ended and neutral questions are considered more effective for engaging speakers and encouraging them to share their genuine thoughts in a listening context. For instance, in a scientific poll design, a leading question is avoided because it may bias the results, whereas a random sample is essential to ensure the poll's representativeness and accuracy.
