D. dictionary
For the purpose of an informative piece (be it an article or essay), you will have a very distinct goal of teaching your audience or readers, by manner of presenting information (demonstrating), how to do something or give them enough information by manner of defining or describing something to where they could do something on their own.
B is correct "A social commentator, who explains what a book says about people in general."
The Storyteller, a classic work of H.H.Munro - known as Saki, talks about a bachelor who tells a story to two young girls who are his travel companions on a train.
Explanation:
This is a story that is straight-forward and direct. It starts to the point where the two young girls are listening to the story being narrated by their aunt. At the end of the story they both express that they have not liked it at all and that it is unreal because of its extreme morale.
The bachelor keeps observing the entire scene and listens to the story. He understands that the young girls want to listen to something realistic, practical and believable. He tells them a story titled as 'horribly good' about a girl who dies because of her goodwill/good deed medals making a noise while she tries to hide from view of a wild animal.
The girls absolutely love the story and exclaim how relating and realistic it is.
THE MORAL OF THE STORY and THE MESSAGE SAKI WANTS TO GIVE to his readers is exactly the same. He wants to tell his readers that righteousness is a trait that all of us must practice but it does not lead us to good ends. It can lead us to bad too. It is not true that good people will end up only in the good experiences. They suffer equally.
This is central message of the story.
