Explanation:
The American women demonstrated their opposition to<em> World War I </em>by forming the <em>Women's Peace Party (WPP).</em> This organization was established by Jane Addams,<em> an American social worker and activist.</em>
The members of this organization believed that "<em>women were the mother half of humanity"</em> and thus, they needed to do something to stop the war.
