Answer:
Hopeful.
Step-by-step explanation:
Diana Garcia's poem "On Leaving" is part of her "On Leaving | On Staying Behind" where she talks of escaping to the border. The escape journey by train would be the main focus of the short poem where she talks about how to be safe throughout the journey.
In the given lines, she talks of how her cousins had told her about "those wearing yellow", people from their village. Such men with yellow bandanas are safe and would be there to help her for "they speak our language, they are known to our village." This presents a hopeful tone to the speaker, for it signifies her safety and that of her cousins who are with her.
