A tag question can be positive when the auxiliary verb used in the tag is also positive. In other words, the tag question matches the polarity (positive or negative) of the statement that it follows.
For example, consider the following statement:
You like ice cream.
A positive tag question that matches the polarity of the statement would be:
You like ice cream, don't you?
In this case, the auxiliary verb "do" in the tag question is positive, which makes the overall tag question positive.
Another example:
John is a good student.
A positive tag question that matches the polarity of the statement would be:
John is a good student, isn't he?
In this case, the auxiliary verb "is" in the tag question is positive, which makes the overall tag question positive.
So, a tag question is positive when the auxiliary verb used in the tag matches the positive or affirmative nature of the statement.
