How do details such as "stone or metal,” "many pigeons,” "towers,” and "wild cats that roam the god-roads” establish setting?

By giving the image in your mind of what the setting will look like with those key items in it.

Explanation:

The answer is because of semantic fields.

Explanation:

A semantic field can be understood as a group of words that are related among them. Putting all the words in the same text (stone or metal, many pigeons, towers, and wild cats that...) setting is established because all of these words together can create the picture of somebody in a room or hallway in a castle, or at least, in a similar environment. It has to be mentioned that the connection between "stone or metal" and "pigeon" is not very close, but if the other quoted words are added, we can talk about a landscape that belongs to a very particular context.

the answer is d, first person always relates to the speaker. i hope this : )
