what do the villagers know about the Khan family chapter 2 of amal unbound

I'm not exactly sure what you are meaning here. The girls transition to a discussion of Amal and Seema’s heavily pregnant mother, Mehnaz. They wonder whether the baby will finally be a boy. The girls notice a new building near their homes and speculate about its function. Hafsa guarantees that Khan Sahib is the only man wealthy enough to afford such a building but doubts he would invest his money in anything positive for their village. Omar, Amal’s best friend rides past her on his bicycle and chimes his bell three times. Amal recognizes his signal and departs to meet him at a stream near her home where they can talk privately.
