Question

What does this line most likely show about the setting of the scene? It takes place in a foreign land because Barnardo does not know everyone. It is dark because Barnardo has trouble seeing the other guard. It takes place in a castle because Barnardo is a guard. It is early in the morning because Barnardo arrives first on the scene.

Answer 1

A setting of a  story is "the location and time frame in which the action of a narrative takes place." (Britannica)

Here, the location is a castle in a foreign land.

The time is morning.

The action of these lines takes place in the castle in the morning. And Barnardo is a guard who appears first on the scene in the morning.
