Some scholars argue that Confucianism in East Asia acted much like:

A) Irish Catholicism in 1800s America.
B) Spanish missionary expansion in the Philippines.
C) Protestantism in 19th-century Europe.
D) All of the above.
E) None of the above.

Confucianism in East Asia, like Protestantism in 19th-century Europe, provided a set of ethical and social guidelines for individuals to follow. Confucianism emphasized the importance of education, family values, and social harmony, much like Protestantism emphasized the importance of individual responsibility, hard work, and personal virtue. Both Confucianism and Protestantism spread rapidly and had a significant impact on the societies in which they were adopted. Irish Catholicism in 1800s America and Spanish missionary expansion in the Philippines are not as apt comparisons, as they were both primarily religious in nature and did not have the same comprehensive impact on society as Confucianism and Protestantism.
