why were political machines difficult to break up?\no they always operated within the law.\no they created a cycle of supply and demand.\no they used violence to intimidate voters.\no they created a cycle of favors for votes.
Answer
Answer:
D. They created a cycle of favors for votes.
Brief Explanations:
Las máquinas políticas ofrecían favores (empleos, ayuda social, etc.) a cambio de votos, creando una dependencia y un círculo difícil de romper. Aunque algunas usaron violencia, la dinámica del intercambio de favores - votos era fundamental para su persistencia. No siempre operaban dentro de la ley y la creación de un ciclo de oferta y demanda no era un factor determinante en su resistencia.
