Answer:
From the story–The House on Mango Street
Explanation:
In this story, particularly in chapter 29 we read about the role of "four skinny trees" in the life of Esperanza which were beside her house. We are told about them: "Their strength is secret. They send ferocious roots beneath the ground. They grow up and grow down and grab the earth between their hairy toes and bite the sky with violent teeth and never quit their anger. This is how they keep".
In a sense, Esperanza is motivated by the trees.
