I believe the answer is humor.
This is because, the mood of danger is shown because of policemen meaning something bad might or could have happened. The mood of mystery is shown because you do not know where the man is, or why the policemen is there. Suspense is shown because the man speaks up quickly.
<span>In his book Walden, a reflection on the act of living as simply as possible, Thoreau spoke at length on the impact of technology on our daily lives and humanity as a whole. He believed that technology was leading to a degradation of our relations with one another and with the natural world. He cited the construction of a telegraph line from Maine to Texas, saying,"We are in great haste to construct a magnetic telegraph line from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate." We can see them same in our modern day quest for the "next big thing"; snapping up the latest iPhone for hundreds of dollars, posting ever more on social media, with many having nothing important to contribute to a wider world despite access to that world at an unprecedented level. As a society, we have at our fingertips the lessons and work of all the world's great thinkers and scholars, and yet a great number of people use the potential at hand to watch funny cat videos. I believe that this is a sign of the degradation that Thoreau spoke of made manifest.</span>
The sentence in the above excerpt from "In Another Country" by Ernest Hemingway which is an example of irony is:
“You are a fortunate young man.”
The story "In Another Country" is about Hemingway's personal experiences in the Milanese hospital. He narrates the stories of the patients admitted with him after the end of the first World War. The story talks about the wounds which the war has given to them, apart from the physical pains. The wounded soldiers wanted to erase the ills and effects which the world war has given to the world. In the above excerpt, it is ironical that the doctor calls the football player 'a fortunate man' after his leg broke off.
C- her, sounds like the best fit for that sentence.
