Final answer:
The result of the campaign for women's suffrage just prior to 1920 was the successful achievement of voting rights for women, culminating in the ratification of the Nineteenth Amendment.
Step-by-step explanation:
According to the interview with the reporter from the Cleveland Plain Dealer, the result of the campaign for women's suffrage in the years just prior to 1920 was that women's suffrage was successfully achieved (a).
This success was the culmination of decades of effort, starting at local and state levels, with women securing the right to vote in several states and gaining significant political influence.
States like Wyoming, Utah, Idaho, and Colorado granted women statewide voting rights by 1900, and by 1910 and 1911, successful campaigns in Washington and California further bolstered the movement.
The momentum continued as the 1912 election saw growing political support for the suffrage cause, with even previously evasive politicians recognizing the political necessity of supporting women's rights.
Finally, the concerted efforts of millions of women, various suffrage organizations, and Progressive men led to the ratification of the Nineteenth Amendment in 1920, granting women the right to vote across the United States.
