Revise the following paragraph so that they are more cohesion and coherence.
Some potential threats exist in the modern mass communications media, though there are many significant advantages. If a powerful minority should happen to control it, public opinion could be manipulated through biassed reporting. And while a wide knowledge of public affairs is a great advantage that result from national coverage, divisiveness and factionalism can be accentuated by connecting otherwise isolated, local conflicts about the same issues are occurring in different places. It will always be true, of course, that human nature produces differences of opinion, but the threat of faction and division may be reinforced when national coverage publicizes uninformed opinions. According to some, education can suppress faction when the true nature of conflicts reaches the public through the media, but history has shown that as much coverage is given to people who encourage conflict as to people who try to remove conflict.
