What does Beatrice have to suppress if she decides to stay in Abnegation While speaking to Caleb about the test, Beatrice hears a train horn in the distance. Explain how this makes her feel?

Beatrice, as a member of Abnegation, must suppress her own individual desires and emotions in order to prioritize the needs and well-being of the community. The train horn, a symbol of the wider world beyond Abnegation and its restrictions, may evoke feelings of temptation and longing for a life outside of Abnegation's constraints. At the same time, Beatrice's sense of duty to Abnegation and its principles may cause her to feel guilty for these feelings, leading to internal conflict and turmoil.
