Final answer:
In The Poisonwood Bible, the first piece of advice that Nathan ignores from Mama Mwanza is to respect the beliefs and traditions of the Congolese people.
Step-by-step explanation:
In The Poisonwood Bible, the first piece of advice that Mama Mwanza gives and Nathan ignores is to listen to the voices of the Congolese people and respect their beliefs and traditions. Mama Mwanza warns Nathan that his rigid and fanatical approach will not be well received by the people of the village.
Instead of taking this advice to heart, Nathan disregards Mama Mwanza's wisdom and imposes his own religious beliefs, considering them superior and refusing to adapt to the local culture. This sets the stage for the conflicts and misunderstandings that unfold throughout the novel.
This disregarded advice by Mama Mwanza highlights the theme of cultural clash and the consequences of ignoring the perspectives of others.
