The correct option is 1.
Step-by-step explanation:
Manny gave a formal presentation about a new product to potential customers. The sentence that shows an effective delivery technique he used is: He spoke clearly and confidently, maintaining eye contact with the audience. Effective speech delivery is critical in conveying a message successfully to an audience. It involves using clear language, proper intonation, eye contact, and expressions to keep the audience engaged and to ensure the message is understood.
Eye contact is a key component of an effective presentation as it helps establish a connection with the audience and conveys confidence in the speaker's abilities. Speaking clearly and with confidence is also imperative; it ensures that the information is communicated effectively without confusion, while maintaining a professional tone. Varied vocal techniques, like changes in speed and pitch, along with strategic pauses, can enhance a presentation, making it memorable and interesting.
Technical jargon, unless well-explained, can alienate an audience, as can reading verbatim from notes without engaging with the audience. Likewise, speaking in a monotone voice, too quickly, or too quietly can make the presentation hard to follow. Manny's technique, therefore, aligns with good practice for delivering a presentation.
