The correct answer is B. False
Step-by-step explanation:
The Progressive Era (1890-1920) was a period in the United States during which important changes occur in society in terms of regulations, laws, rights, among others. In the case of female Progressives, their main goal during this time was to ratify the right of women to vote. Indeed, during this time the National American Women Suffrage Association was founded, and this along with the effort of all women led to the Nineteenth Amendment that established vote was a right no matter the sex. Additionally, during this era women fought to participate in community and social issues and there were changes in the ideas related to marriage and sexuality.
According to this, it is false the primary concern for female Progressives was women's right to fight in the military because the main concern during this time was the women's right to vote and only later (around the 1940s) women fought to be part of the army and similar.
