In the late 1800s and early 1900s, violent riots were started in several chinatowns by
a. nativists who were angry and resentful of newcomers.
b. immigrants who were being denied their rights.
c. laborers who were unemployed.
d. city workers who were being denied their wages.

Option A, natives who were angry and resentful of newcomers, is the right answer.

The immigrants from China were extreme to work because of many reasons such as sending money to their families, to pay the debts of the merchants who sponsored their journey to America. Therefore, the Chinese immigrants worked hard to fulfill their need for money.

But this action of the Chinese immigrants soon drew the anger of the native Americans, as these native Americans considered that the immigrants have removed out of certain jobs . Therefore, this led to several riots in the Chinatown by the natives.
