Answer 1

Answer:

The joy of the lawyer turned into disappointment when he reached New Mullion​ because he had thought it would be a beautiful, idyllic place; but It turned out to be quite a dirty and squalid town. Its streets were  rivers of mud, with rows of wooden shops, which were either painted a sour brown,  or bare of any paint at all.
