The correct answer is B) A small group organized demonstrations against the curriculum change.
The cause was that a small group organized demonstrations against the curriculum change.
The many editorials that were written in the newspaper were in response to the small minority that had an aversion to change and thwarted the plans by organizing demonstrations. This represented the active participation of the group of students that favored changes in the school curriculum and that support the environment. That is the only way to exert some kind of pressure to defend their right to have a better curriculum that makes them progress.
