Ask the interviewee an open-ended question. For example, use questions that start with "who," "what," "when," "where," "how" and "why." This will help you avoid "yes" and "no" answers.
Ask questions that get at the heart of the issue, especially when someone isn't giving all the information. For example, if someone says taxes will go up this year, ask them by how much and how many dollars that means to the average resident in a given period.
Find out all of the information necessary for a complete story. Your readings will want to know the "who," "what," "when," "where," "why" and "how" of the story.
Quote someone who is asking a question by placing the question mark within the quotation. For example, "Wouldn't you have made the same tax cuts?"
