Final answer:
Nick and Hanifa face challenges related to cultural factors that influence their roles and responsibilities within the family, akin to the experiences studied by researchers focusing on migration and diaspora.
Step-by-step explanation:
Nick and Hanifa are both engineers who face major challenges in their lives. One of the challenges they face is the cultural factors that affect the way they view their individual roles and responsibilities in the family. This concept is similar to research conducted by Attiya Ahmad and Ritty Lukose, who have studied how migration and diaspora impact individuals' lives and their integration into new cultures. Migrants often deal with shifts in their identity and the expectations placed upon them both in the country they move to and upon returning to their homeland. This leads to a complex interplay of new cultural norms and the retention of traditions from their original culture.
