Explanation:
This passage has a melancholic mood. You can tell this due to some specific key words: "dull", "dark", "soundless." They all have a negative connotation. The imagery of a lone rider in a dreary and dull country under the oppressive sky may clue you in that the overall passage has a sad tone to it. Even later in the passage the author states that the scene is melancholic.
In a way i would prefer a question because how can you get the answer without given the question or visa versa. So if it would be question the explanation would be it helps you decides who,when,what,where........
And if it would be answer it would be answer helps you can elaborate to help you know more. hope this helps. i tried my best
