This question refers to the article "The yuckiest food in the Amazon." In this article, author Mary Roach describes her experiences sharing food with a tribe in the Amazon. The host of such an experience is Isaac. The author describes Isaac's living room as a low log bench in the open-walled platform. The floor is dirty but uncluttered. The decoration consists of parrot feathers, jaguar skulls and a government poster urging vaccinations for children. The main reason why Roach includes these details is because she wants to create an image in the mind of the reader in order to better understand what the experience was like for her.
