You didn't give us answer choices, but we can at least define "rotten boroughs" for you here ... and that may be enough to lead you to the correct answer.
A "rotten borough," also sometimes called a "pocket borough," was a borough or area that had a representative seat in Parliament but no longer really had much population in the borough. People had moved to the cities in droves due to industrialization. But as old parliamentary regions retained their representation in the House of Commons, their small electorate could be controlled by a small faction, or even by a single person. That's where the term "pocket borough" came from, as a whole representative district was essentially "in the pocket" of a single powerful person or family in that district.
Obviously all of that is bad for democracy. Democratic processes work best when the people are represented fairly. How boroughs for Parliament were drawn up, or how congressional districts for the US Congress are drawn up today, has an affect on how people are represented democratically. In the USA today, we have a sort of similar problem in what are called "gerrymandered" districts. Look up that term to learn more!
What helped Ronald Reagan win the presidential election of 1980 were D. his gifts as a polished communicator.
People loved what they heard Reagan speak, that is why they chose him to become their next president in the 80s. If he hadn't been such a good communicator, then his opponent would have won.
I'm pretty sure the answer is B. Supreme court has unlimited jurisdiction.
My only doubt is supreme court cases can be overruled but only by the supreme court (which is A).
Explanation:
The Bolsheviks had to use violence to start and to maintain a communist state because of how most people didn't believe in the Bolsheviks or the communist regime and tried to block them whilst other countries like Britain and America AND China were sending support for the Whites (The Original Government) to retake control of the country so that there wouldn't be revolts like the one in Russia across the whole world.
