The more questions asked, the more answers there become. Questions lead to new knowledge, and from the beginning of time questions are what created what we know today. It is important that we educate in questions and answers, not only to provide knowledge but to make people realize its acceptable to ask what they may be thinking, and question whenever they are unsure in life.
Providing education with questions and answers is more engaging, more thought provoking and creates more discussion when people have different answers and opinions on the subject. Instead, when providing simple information and facts with no questioning, or possible answers, it is a more simple way to learn information and may be less engaging as the question/answer way to do it.
