Read the sentence from “Eleanor Roosevelt on Civil Liberties.”


I think that is, perhaps, one of the greatest things that the civil liberties committees do, and I wish we had one in every place throughout the country--one group of people who really care when things go wrong and do something when there is an infringement of the individual’s rights.


Which sentence from “Fighting for Everyone’s Rights” best supports the idea that the ACLU achieved Roosevelt’s wish?

“The ACLU is an organization that provides lawyers and legal advice in cases where civil rights may be in danger.”

“In 1920, a group of people who were upset by the Palmer Raids formed the American Civil Liberties Union.”

“The ACLU’s work helped make freedom of religion, freedom of speech, equal treatment under the law, and other rights become real for millions of people.”

“The ACLU began as a small group of individuals protecting the rights of immigrants.”
