For 17. I select d. First too. The Supreme Court had ruled to government to punish an individual for statements that were considered threatening, dangerous or untrue. This shows there is exception to Free Speech.
For 18. I select b. The Thirteenth Amendment to the Constitution too. It states, "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
For 19. I chose a. a request for an equitable lien on property too. This took a little more research to gather answer.
For 20. I select b. compel action or force cessation of action. It is not about money. A typical equitable remedy is a restraining order where nobody pays money but someone has to stop doing something (like polluting or making too much noise). Injunctions are examples of an equitable remedy. The answer you picked, c. award only monetary damages is an example of a legal remedy.
