Final answer:
The recurring critical incident in the chapter likely relates to the characters Delia and Velia almost disclosing the truth of a dead body to border patrol officers, highlighting the dangerous and fraught nature of border crossings. Option c is the correct answer.
Step-by-step explanation:
The critical incident that occurs multiple times in the chapter under consideration appears to deal with encounters and events that highlight the difficult experiences of those crossing borders and dealing with immigration authorities.
Based on the details provided in the excerpts, which speak to the various trials faced by individuals crossing the border—such as being bewildered and distraught children questioned by border officers, migrants left to their fate by smugglers, and the perils of the journey through harsh environments like the Sonoran Desert—it is reasonable to infer that Option C: Delia and Velia almost reveal the truth of the dead body to the border patrol officers could represent a recurring critical incident in the chapter.
This option suggests close calls with border authorities, which fits within the broader theme of border challenges and close encounters with law enforcement.
