Step-by-step explanation:
When determining a topic, the basic question that helps determine the speaker's enthusiasm for a topic is 'What are the speaker's interests and hobbies?' This is because personal interests and hobbies are typically areas where individuals have intrinsic motivation and genuine curiosity, which often translates into enthusiasm when discussing or presenting on the subject.
Exploring the speaker's interests serves as a quick launch for finding and focusing on a topic that captures their passion and engagement. It is this energy and passion that will help generate a positive tone during a presentation, thereby maximizing the effectiveness of the communication with the audience. Conversely, the speaker's qualifications and expertise, personal experiences, and opinions, and beliefs may also play a role in passion for the topic, but interests and hobbies are often the most direct reflection of what excites them.
In answering questions such as what the speaker finds most fascinating about the subject, what important aspects may be overlooked, and what issues are personally important to the speaker, one can further delineate the depth of the speaker's enthusiasm and refine the topic to be both engaging and informative.
