The two sources disagree on the effectiveness of recycling programs in schools. Source 1 emphasizes the necessity and potential positive impact of school districts participating in recycling to reduce greenhouse gas emissions, implying that participation can lead to successful outcomes. In contrast, Source 2 points out the difficulties in getting all students to follow a specific recycling program, suggesting that this can make recycling efforts ineffective. Therefore, the disagreement lies in the effectiveness and feasibility of implementing recycling programs in schools.
However, since none of the exact response options provided match this assessment, the closest response would be:
"There are too many people in a school district to follow one plan."
This reflects the concern present in Source 2 about the challenges of participation because of the large number of individuals involved, which Source 1 does not address.
