The correct answer to this open question is the following.
What are some responsibilities of the media?
The main responsibilities of the media are to objectively inform people about current issues on politics, economics, education, culture, sports, show business, and other current topics that could have a social impact.
I would like to highlight the word "objectively," which means to never bias information to one side or the other, to one ideology or private interests in particular.
How has increased social media impacted citizens' ability to gain information?
It has impacted citizens in that they have more channels, webpages, and social media sites to choose from and watch or read the news. However, it's important to say something. Not everything we watch and read on social media is true. There are a lot of unofficial or amateur channels that have nothing to do with the truth. They only create misinformation and that is a big risk when citizens are uninformed.
