Final answer:
The word 'distraught' in the passage indicates that Jia was agitated, evidenced by her anxious behavior after missing the bus.
Step-by-step explanation:
Based on context clues in the passage, the most likely meaning of distraught is agitated. The description of Jia pacing back and forth, wringing her hands, and trying not to cry suggests a high level of emotional distress or anxiety, which aligns with the definition of being distraught as deeply upset and agitated. This is in contrast to being simply tardy (late), doubtful (uncertain), or earnest (serious and sincere). The context does not suggest these other emotions, focusing instead on her intense, worried reaction to missing the bus and potentially losing her job.
