Final answer:
Without the specific literary text that mentions Mr. Pirzada, it's not possible to determine why the narrator's parents invited him to dinner. The provided context suggests a variety of interpersonal connections and motivations, but the exact answer requires reference to the specific work of literature.
Step-by-step explanation:
The context provided does not directly mention Mr. Pirzada or the reasons for his invitation to dinner. However, all given narratives involve interpersonal relationships and how people are perceived or interact in society. It is likely that the question is referencing a specific work of literature where Mr. Pirzada is a character. In such a case, one would need to refer to the specific text to understand the motivations behind Mr. Pirzada's invitation to dinner. Without the text, it is not possible to discern whether the narrator's parents invited Mr. Pirzada due to a sense of pity, due to familial relationships, the desire for companionship, or the need for their daughter's tutoring. From the provided contexts, it could be inferred that individuals often reach out to others in situations where they recognize a predicament or feel a connection, whether through shared experiences, social kindness, or mutual benefits.
