This is an easy one, but nevertheless a lot of presenters fall into this trap. In typical Q&A situation, a person is given attention. A question is posed to the presenter. But, as the direction of the mouth is towards the front, hardly anyone sitting behind the person talking hears the question. Just hearing the answer is like Jeopardy. A nice game for in front of TV, but not for audiences towards you want to send excitement or selling something.
There are two ways around this. One is in having a pro equipment with headset and a hand-around microphone. Sets like this are available for not to much money, but are not suitable for typical corporate or community presentations.
The other, far easier one is to just repeat the question. This serves two purposes. The less important one being that all have heard the question and are prepared to hear the answer. Even more important is that this serves as verification if the question has been understood correctly. As a side note, it allows to “fine-tune” the question within a certain degree if the answer is not within your preferred zone…
