Answer:
Option 2. The tension on the street will steadily increase.
Step-by-step explanation:
Foreshadowing in Literature reflects when the writer starts his story. It is when the author gives a clue about further developments to come from the beginning of the story. When an author uses foreshadowing in his writing, he creates a mood of suspense. Foreshadowing makes the readers anticipate what is to happen in the story. Examples of foreshadowing are Charles Dickens' Great Expectations, John Steinbeck's Of Mice and Men, Alfred Noyes' The Highwayman, etc.
From the excerpt, option 2 is more appropriate.
