Answer:
Division.
Step-by-step explanation:
Social changes usually come about through fortuitous historical circumstances aided by explicit propositions that fit the historical moment in question —propositions such as those presented by individual thinkers adopted by social movements or by the conjunction of the premises fueling the movement collectively. As such, it is seldom the case that a movement can be thought of as monolithic; more often presenting diverse perspectives that, in the long run, if not coordinated, can present unsalvageable divisions within the movement that can bring about its disappearance.
