who does Kambilis family meet in chapter 6

Kambili’s cousins arrive: Amaka, 15, an inquisitive teenage girl, Obiora, 14, an intelligent and assured boy, and Chima, big for his seven years. All kids share their mother’s throaty laugh. Amaka asks if they can watch CNN on the Achike's satellite TV. Kambili nearly chokes every time Amaka speaks to her, but she manages to explain they don’t watch much TV. Amaka sneers and asks if she is bored with satellite. Kambili lets the insult pass and does not tell her cousin the truth – TV time is not in her schedule. When they leave, Obiora and Chima say goodbye. Amaka does not turn back to her cousin.
