Which fallacy might be represented by a teacher saying, "Come now, she isn't much of a student, is she?"

The statement made by the teacher exemplifies a leading question because it suggests a particular answer or influences the respondent to agree with a preconceived notion. A leading question subtly guides someone toward a specific conclusion by framing the query in a way that implies the correct response aligns with the speaker's perspective. In this case, the teacher's question implies that the student lacks merit or value, thereby influencing others to perceive her negatively.

There are other types of reasoning or rhetorical strategies at play, but they do not capture the essence of how the question is structured and the intent driving it. The statement doesn’t require a response based on genuine inquiry but rather steers the listener toward discounting the student's capabilities. Thus, it effectively exemplifies the nature of a leading question.
