What is the connection of free press to the American political system

Freedom of the press is an essential right in the United States and a core principle of democracy. Protected by the First Amendment to the U.S. Constitution, a free press helps maintain the balance of power in government.

i believe it d) heterogeneous

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
