Dealing with questions will be as intimidating as delivering the presentation itself, and a few presenters might choose to skip the method entirely.
To properly conclude your presentation and respect the link you have developed along with your audience, you wish to permit for questions.
When answering questions, acknowledge the speaker and repeat the question so the whole audience can hear it. Avoid stepping into a debate or argument, and if you are doing not know the solution to the question, admit it. invite the contact information of the person asking the question and offer to induce back to them with a response later.
