Step-by-step explanation:
Stefano's small group has adopted the method of a symposium for presenting its recommendations on a policy for increasing child safety in the homes of gun owners. During a symposium, each member delivers a prepared speech on a different aspect of a topic, which allows for a comprehensive exploration of the subject. This method is effective for presenting researched information and allowing experts to delve deeply into specific areas of a topic. This contrasts with other methods such as panel discussions, which involve spontaneous interaction among experts, or open forums and convocations, which are more general methods of gathering and discussing input on a topic.
