Final answer:
Abigail Adams' last act of defiance was advocating for political pluralism by expressing her desire for women to have a voice in the new government.
Step-by-step explanation:
Abigail Adams' last act of defiance was advocating for political pluralism.
In her letter to her husband, John Adams, in 1776, Abigail Adams expressed her desire for the delegates, including her husband, to remember the ladies and be more generous and favorable to them in the new code of laws. She believed that women should have a voice in the new government and warned that American women would engage in their own rebellion if they were denied that voice.
By advocating for political pluralism and challenging the existing male-dominated power structure, Abigail Adams was defying the norms and expectations of her time.
