Generally, all of the above. The context of the "media" matters to answer this question properly, though. For instance, you don't need 2 or 3 if it's news, you only need to understand it, and make sure it comes from a reliable source.
You need 2 and 3 if it's something about a protest that you saw on some social media site (3 requires 2, by the way, you can't be compelled to action without an emotion being sparked).
