You do not understand a part of the speech of the speaker, or you want to know something about the subject. The question you pose is neutral. Positive question This type of question is to assist the speaker if you agree with him. You can do this by wrapping up an important argument of the speaker in the form of a question, providing with an example or by coming forward with a new argument. There are of course also pestering questions.
Examples are legion.
Do not use this type of question too often and form them delicately. It is easy to use these questions, since you immediately force the speaker in a defending position. On the hand, you run the risk of being seen as a delegate who is only nagging, which certainly is no good for your reputation and credibility. It is wise to answer at least one question after your speech. Do not be afraid, people often listen more intensely because the assembly is more actively involved.
