Pick two scenes in which the senses (sight, sound, etc.) work with space (where people are, why, who) to produce an understanding of racial dynamics

So my prompt is: Isolate and discuss two scenes in the novel in which the senses (e.g. sight, sound, etc.) work in concert with space (where people are located and why, the character and meaning of those spaces) to produce our understanding of the racial dynamics at work in the book. How does Boyle try to make us see, hear, feel, smell, and/or taste whiteness, Mexicanness, and intersections/interactions thereof? How are these sensual perceptions shaped by the spaces and the spatial arrangements in which they occur?

Any help is appreciated!!!!
