Final answer:
Marji's father likely visited Khosro for assistance related to the political turmoil in Iran, depicted in the graphic novel 'Persepolis'. Khosro's motives for helping could have been due to shared political views or personal relationships.
Step-by-step explanation:
The question appears to be referring to the character Marji and events surrounding her family, which suggests the subject matter is from the graphic novel Persepolis by Marjane Satrapi.
In the context of Persepolis, the reason Marji's father visited Khosro was likely linked to the political and social upheavals occurring in Iran during the time period described in the novel.
Although the provided texts do not contain specific details about Marji, Khosro, and her father, considering the historical background of Iran, Khosro's motive for assisting him could have been influenced by shared political views, a sense of solidarity among those opposed to the regime, or perhaps a personal friendship.
It's important to understand the backdrop of the Iranian Revolution and the subsequent unrest, which are central themes in Persepolis, to fully comprehend the motives of the characters.
