Only rarely should you refer to other portions of the Bible, and then only at the request of the leader. Of course, the Bible is internally consistent. Other good forms of study draw on that consistency, but inductive Bible study sticks with a single passage and works on it in depth. These are discussion studies. Questions in this guide aim at helping a group discuss together a passage of Scripture in order to understand its content, meaning and implications.
Most people are either natural talkers or natural listeners.
Yet this type of study works best if people participate more or less evenly. Try to curb any natural tendency to either excessive talking or excessive quiet. You and the rest of the group will benefit. Most questions in these guides allow for a variety of answers. If you disagree with someone else's comment, gently say so.
