Because an editorial is an article that presents the newspaper's opinion on an issue.
Therefore editorial writers must be able to
use arguments to promote an opinion or a point of view.
I don't know if this is correct but I would choose B) distinguish between fact and opinion. The reason is because an editorial writer is supposed to make sure everything is fact and accurate, and they are supposed to record information faithfully. On the other hand, reporters tend to twist peoples words and make events seem bigger than what really happened.
