Question

how did us labor unions treat chinese immigrants in the 1800s?
○ labor unions discriminated against chinese immigrants and did not allow them to join.
○ labor unions helped chinese immigrants find jobs in factories and mills.
○ labor unions asked employers to pay chinese immigrants lesser wages than union members.
○ labor unions helped chinese immigrants form their own unions.

Explanation:

In the 1800s, US labor unions often held nativist and discriminatory attitudes toward Chinese immigrants. They feared Chinese immigrants would take jobs and drive down wages, so they excluded them from joining unions. The other options are incorrect: labor unions didn't help them find jobs or form unions, and they opposed employers paying Chinese less (as they saw Chinese as competition, not as a group to underpay in that way).

Answer:

A. Labor unions discriminated against Chinese immigrants and did not allow them to join.
