Final answer:
The older villagers disapprove of Leah's hunting because it goes against their traditional gender roles and threatens the community's food supply.
Step-by-step explanation:
The older villagers in The Poisonwood Bible disapprove of Leah's hunting because it goes against their traditional gender roles and expectations. In their culture, hunting is typically seen as a male activity, and the fact that Leah, a young girl, is taking part in hunting goes against their beliefs. They may also disapprove because Leah's hunting skills may be seen as a threat to the community's food supply, as she could potentially scare away or kill the animals that they rely on.
