How did the socialist movement connect to the women’s suffrage movement?

Socialist movement really helped to further the women's suffrage movement. Socialists really challenged the "accepted" ideas that women were some how inferior. The basic doctrine of socialism and the ideas of people being equal really backs the ideas that women should be able to vote. They should be able to vote because they are the same as men. They should also have a say in the running of the government. 

(d) it was complex and capable of highly organized efforts.
