What event were Dahl and Coke anticipating during their time in Argos?

Dahl and Coke were anticipating a potential attack by the Germans during their time in Argos. This context is vital to understanding the atmosphere and sense of urgency described in "Going Solo." They were in a location where tension was high due to the ongoing war, and the anticipation of an enemy attack created a situation that demanded vigilance and readiness. This preoccupation with potential danger influenced their actions and decisions as they prepared for what could happen next, showcasing the ever-present threat that war imposed on their daily lives.

In contrast, the other options, while they could be relevant in a wartime scenario, are not the focus of their immediate concerns during that period in Argos. There was no indication that their primary objective revolved around meetings with local officials, rescue missions, or supply drop operations at that particular moment, making the anticipation of an attack the most fitting choice in this context.
