How many shares does Dahl mention regarding the khaki shirt?

In "Going Solo," Roald Dahl refers to his khaki shirt with the emphasis on how many shares were allotted to him. He humorously remarks that he only has one shirt. This detail illustrates the simplicity and modesty of his situation at the time, highlighting his experiences during the war. The mention of 'one' shirt serves not just as a factual statement, but also adds to the narrative of his resourcefulness and adaptability in challenging circumstances. This context shows that the choice of one is both a literal count and a reflection of his life experiences during that period. Other options do not align with the narrative since Dahl clearly points to just having a single khaki shirt, emphasizing its significance in his recollections.
