Answer:
D. Passage of the 19th Amendment.
Step-by-step explanation:
The given speech by Alice Paul shows how she warns the women suffrage movement to not think they have achieved anything extraordinary. Rather, the implementation of the 19th Amendment only allows them the equality to cast votes but not in any other sphere. So, she is pointing out the flaw in it, that they have a more bigger obstacle of fighting for the rights of women in attaining equality in all spheres. She warns them to not think that this "great victory" is the end of their struggle. She wants them to act more passionately in their struggle "to remove the remaining forms of woman's subordination".
