The answer is A, the national and state governments share power.
Answer:
Social media makes it faster to spread rumors and misinformation, weather about a person or topic.
If someone posts something controversial, say, which president is better, then they might get a lot of hate drawn to them from people of the other side, and from people personally disagreeing with them.
Im not sure what answer this would go to exactly, but the magna carta limited the power of the monarchy by creating a parlament. So, I guess the answer would most logically be A.
