This question will resolve based on the change in polls as reported by 538, from June 27 (the day of the first debate) to July 4th (a week after).

This will use the polls as reported to the nearest 0.1%; all answers are inclusive.

For example, if the poll result on June 27th is Trump +0.7 (where it is as of question writing) and then on July 4th it is Trump +0.2, that is a swing towards Biden of 0.5 points, and the answer "Biden +0.3 to +0.9" will resolve Yes and all others No.
