Question

drag and drop one dash into the sentence to indicate a pause or break.
—
the attorney felt irritable so disgruntled, in fact, that he could hardly focus on the details of the case.

Explanation:

To indicate a pause or break, we place the dash after "irritable" to separate the description of the attorney's feelings. The sentence becomes: "The attorney felt irritable — so disgruntled, in fact, that he could hardly focus on the details of the case." This use of the dash creates a pause to emphasize the degree of his disgruntlement.

Answer:

The attorney felt irritable — so disgruntled, in fact, that he could hardly focus on the details of the case.
