Prompt

The study found that longer waiting time during recess queues affected the punctuality of students in returning to their classes. Students who spent more time falling in line had less time to buy food, eat, and prepare for their next subject, which made them more likely to return late to their classes. The study also showed that the length of the queue and the speed of canteen accommodation influenced students’ waiting time. This means that when the line was long or the service was slow, students had a greater probability of being tardy. which sentence should be removed?
