What tactics would have been used by Alice Paul's more aggressive followers? Select two options
picketing in public areas
engaging in hunger strikes
writing newspaper articles
lecturing at public conferences
organizing letter-writing campaigns

Answers

Answer:

picketing in public areas

engaging in hunger strikes

Explanation:

Picketing in public areas and engaging in hunger strikes are the tactics would have been used by Alice Paul's more aggressive followers. Hence, option A and B is correct.

What was Alice Paul's personality like?

Paul's leadership style mixed stereotypically feminine and masculine characteristics in a way that either engendered ardent loyalty or stoked intense hostility. She had a fragility that dispelled worries about her militant history and her intense drive because of her dread of the limelight and ingrained shyness.

Alice Paul was a prominent figure in the women's suffrage campaign of the 20th century. She worked to get the US Constitution's 19th Amendment, which gave women the right to vote, passed. The Equal Rights Amendment, which Paul then wrote in 1923, is still not in effect.

Alice Paul was a militant and outspoken leader in the women's suffrage movement who split from the National American Woman Suffrage Association to found the National Woman's Party, which advocated for more radicalization.

Thus, option A and B is correct.
