Question

Read the passage. I had only been a detective for a few months when I was hired to investigate a very odd case. Traveling across town, I soon found myself walking down a dim, dingy street, looking for the law offices of one “L. Creighton, Esq.” Entering the office, a very calm, well-dressed gentleman warmly greeted us. I was surprised to find the office spacious, neat, and clean. Somehow, I had expected to see a cramped, untidy, and dismal space. What did the detective expect to see in the offices of the accountant? a mysterious doctor a large and prosperous office a dangerous warehouse a small, unclean office

Answer 1

A small and unclean office is the answer 

Answer 2

The right answer is "a small and unclean office ".

The answer to this question expounds, literally in the text. The excerpt that shows this is:  " I was surprised to find the office spacious, neat, and clean. Somehow, I had expected to see a cramped, untidy, and dismal space."

Basically, the character is surprised to find a clean, spacious and tidy place, because he expected exactly the opposite, that is, a small, dirty and untidy desk.
