Final answer:
The 'great tragedy' often involves loss or emotional pain, shown in various literature examples where characters experience deep distress or transformation, such as Nora in 'A Doll's House'. Vera is revealed to lie or invent stories.
Step-by-step explanation:
The term "great tragedy" in literary context often refers to a devastating event causing emotional distress or death. However, the concept of tragedy has evolved, and modern dramas may not end with death but instead focus on deep emotional or psychological suffering, as seen in the example of Nora from A Doll's House. In the story mentioned in the question, we learn that Vera's tendency to fabricate stories emerges clearly at the end, serving as a revelation to her character's nature.
