Which of the following contributed to the passage of the 19th amendement

the desire to have everyone pay an equal share of income tax

Women's Suffrage:During America's early history, women were denied some of the basic rights enjoyed by male citizens. For example, married women couldn't own property and had no legal claim to any money they might earn, and no female had the right to vote. Women were expected to focus on housework and motherhood, not politics. The 19th Amendment to the U. S. Constitution granted American women the right to vote, a right known as women's suffrage, and was ratified on August 18, 1920, ending almost a century of protest. So protest by women can factor leading to the passage of the 19th amendment. In 1848 the movement for women's rights launched on a national level with the Seneca Falls Convention organized by Elizabeth Cady Stanton and Lucretia Mott. Following the convention, the demand for the vote became a centerpiece of the women's rights movement.
