Read the passage. (1) One high school shifted its opening time forty-five minutes later for a semester. Morning attendance improved, and fewer students arrived during first period. (2) The pilot coincided with a revised attendance reminder system, and the school did not find a consistent change in course grades. Coaches and families also reported new transportation conflicts for some afternoon activities. (3) The district is reviewing attendance, transportation, and student-wellness data before deciding whether to continue the schedule. Which ending gives the most balanced conclusion about the later-start pilot?
