Question

maintaining the current nine-month school year is essential to keeping students in school. despite a limited statistic showing a smaller dropout rate, students in year-round school would find more stressors added to their already overwhelming lives. while the american education system does need to be reformed, changing the schedule is not the way to do it.
what makes this a strong conclusion?
it ends with a call to action for all schools to change to a year-round schedule.
it ends with a judgment that reform is needed but that the schedule should be left alone.
it ends with a judgment that students will not be affected regardless of any changes.
it ends with a call to action for students to participate in school reform.

Explanation:

The conclusion acknowledges the need for education system reform but specifically argues against changing the nine-month school schedule, which is a targeted, judgment-based stance that directly addresses the core debate of the text. The other options are incorrect: it does not call for a year-round schedule change, does not claim students won't be affected by changes, and does not call on students to participate in reform.

Answer:

It ends with a judgment that reform is needed but that the schedule should be left alone.
