Political rights for women grew most rapidly on the western frontier primarily because

(1) the settlers were influenced by native american indian societies

(2) women greatly outnumbered men in the west

(3) pioneer life often required men and women to share responsibilities equally

(4) immigrants settling in the west brought ideals of gender equality from europe

pioneer life often required men and women  to share responsibilities equally

Explanation:

The Pioneer Life was hard, the family usually blended together so everyone could work and contribute to the success of the homestead. Despite the fact that men usually did the heaviest work, women and children also worked hard and carried significant responsibilities. This caused the political rights movement to grow on the western frontier.
