Final answer:
Jin Wang's thought of aggression toward Wei-Chen upon his arrival indicates that Jin has become more confrontational, revealing a negative shift in his character from his initial behavior at Mayflower Elementary. Therefore, the answer to the question is: C. Jin Wang has become more aggressive and confrontational.
Step-by-step explanation:
When Wei-Chen arrives at school and Jin Wang immediately thinks, "Something made me want to beat him up," it reflects a significant shift in Jin Wang's character since he first started attending Mayflower Elementary.
Initially starting as a more passive and possibly more friendly individual, Jin Wang's transformation into someone who harbors aggressive thoughts towards Wei-Chen speaks volumes about his internal struggles and changes. This change in his character could be attributed to various factors such as a need to adapt to new social norms, internal conflict about his identity, or the influence of peers and the environment around him.
Considering the context from the text and understanding the nuances of human behavior and character evolution, the sudden urge to engage in violence suggests a decrease in tolerance and an increase in confrontational behavior. Therefore, the answer to the question is:
C. Jin Wang has become more aggressive and confrontational.
