Why might a videoconference be preferred over a voice conference call?

A videoconference is preferred over a voice conference call primarily because it enhances communication through nonverbal cues. Nonverbal cues, such as body language, facial expressions, and gestures, can significantly impact the effectiveness of communication. In a videoconference setting, participants can see each other, which helps to convey emotions, reactions, and engagement levels that are often lost in an audio-only setting. This visual element facilitates a deeper understanding among participants, fosters stronger connections, and can lead to more productive discussions by allowing for immediate visual feedback.

While the other factors mentioned in the options may have some relevance in different contexts - like potential technical support or cost considerations - they do not contribute as directly to effective communication in the way that nonverbal cues do. In a voice call, the absence of visual elements can sometimes lead to misunderstandings or a lack of engagement, making videoconferencing a more effective choice for collaborative discussions and presentations.
