Passage Summary: Even though small classes are usually better for kids, this district shouldn't do it because they'd end up hiring bad teachers just to fill the rooms, which ruins the benefit.

Conclusion: Reducing class sizes in this specific school district will likely fail to improve overall student achievement.

Reasoning: Smaller classes require more teachers, but a local shortage means the district would have to hire underqualified staff, which negatively impacts education.

Analysis: The educator is weighing two competing factors: the benefit of individualized instruction versus the harm of underqualified teachers. For the conclusion to hold, the educator must assume that the 'bad' of the underqualified teachers is at least as strong as the 'good' of the smaller classes. Look for an answer that confirms this trade-off is negative or neutral for the students. If the benefits of small classes were so massive that even a mediocre teacher couldn't ruin them, the argument would fall apart faster than a substitute teacher's lesson plan.
