Final answer:
The correct word to complete the sentence is 'contrite', which implies a sense of remorse that the bankers do not feel.
Step-by-step explanation:
The correct answer to fill in the blank is 'contrite'. Far from being contrite, those bankers I know who are not in line for bonuses express a kind of contemptuous mirth at having to do their jobs "only for the salary." The word contrite means feeling or expressing remorse or penitence; affected by guilt.
Given the context of the sentence, it suggests that instead of feeling guilty or remorseful about their situation, the bankers feel a scornful amusement. The other options do not make sense in the context provided. 'Unassisted' implies not having help or support, 'gory' is associated with violence or bloodshed, and 'overwrought' implies that someone is in a state of nervousness, excitement, or anxiety.
