Answer:
Cooking was the most important part of Thanksgiving for Carrie.
Step-by-step explanation:
When Carrie saw the kitchen in her brother's dormitory in London, she believed that it was like a coffin and she wondered how they would do their cooking for Thanksgiving there because, for her, cooking was the most important part of Thanksgiving.
Her consistent complaints about what she felt the food in London would look like showed that she was particularly interested in food and cooking. It was only the presence of her brother that calmed her down everything in London seemed to annoy her.
