Final answer:
The statement is true; suffragettes actively picketed the White House to push for an amendment granting women the right to vote, which was realized with the 19th Amendment in 1920.
Step-by-step explanation:
The statement that suffragettes picketed in front of the White House for an amendment that would give women the right to vote in America is true. This form of protest was part of the broader women's suffrage movement and began in a significant way starting January 1917, during President Woodrow Wilson's term. The picketing was integral to the public pressure that resulted in the passage of the 19th Amendment in 1920, which ultimately granted women the right to vote. These suffragettes, such as members of the National Woman's Party, used various strategies to draw attention to their cause, including public protests, legal arguments, and hunger strikes. Despite facing arrests and violence, their steadfast efforts contributed to achieving voting rights for women.
