How is zhu changed by the journey to the west

I believe the answer is that Zhu Bajie becomes better version of himself and is given reward of being the “Cleanser of the Altars”.

 

In “Journey to the West”, Chinese novel written during the Ming dynasty (16th century), attributed to Wu Cheng'en, Zhu Bajie (Pig) doesn’t achieve enlightenment as his fellow pilgrims. Although, Zhu becomes much improved version of himself, he is still too much a creature of his base desires. As a reward for his pilgrimage's success, he is rewarded with a job as "Cleanser of the Altars" and all the leftovers he can eat.

This was already the answer "the use of academic language creates an angry and disdainful tone. the use of academic language gives the text a serious and instructive tone. the use of words with strong connotative meanings creates a sorrowful tone."

The answer is a. society, sociology is the  systematic study of social interaction. it's a social science.
