The group should encourage the person who has not spoken to speak.
The correct answer is to encourage the person who has not spoken to speak. When in a group discussion, it is important to ensure everyone has the opportunity to contribute their thoughts and ideas. Encouraging the person who has not spoken yet helps create an inclusive and respectful environment where everyone's opinions are valued. Mocking or repeating everything that was already said would not be productive or respectful to the person who has not spoken yet. Moving quickly to the next topic without giving the person a chance to speak may result in excluding their perspective, limiting the overall effectiveness of the group discussion.
