The answer is letter C and B. Puerto Rican citizens do not vote for the president. They are US unincorporated territory and they are considered American citizens and are using the US Dollar as currency. Just like Guam, they can freely move to any any another place in the US.
The correct answer would be the Espionage Act of 1917.
The Supreme Court decided, unanimously mind you, that the Espionage Act of 1917 was constitutional and that the defendants who took upon themselves to distribute flyers about resisting induction to the men who are of age to be drafted can be convicted of obstructing the draft.
Answer wouldn’t be B because the Sherman Anti-Trust Act of 1890 forbade any restraint of commerce, which was used against labor unions. However, the Clayton Anti-Trust Act, passed during the progressive era, exempted unions from the Sherman Anti-Trust and stronger enforced the act. The Elkins and Mann-Elkins Acts didn’t really do anything for labor; they just gave the ICC more power to regulate railroads and interstate commerce, along with the Hepburn Act.
In short, best answer would be A.
