In the early 1860s, chinese immigrants came to the united states to
a.
escape industrialization in china.
b.
work in factories in chicago.
c.
escape religious persecution.
d.
work on the transcontinental railroad.

I believe that the correct answer that would best complete the given statement above would be option D. In the early 1860s, Chinese immigrants came to the United States to work on the transcontinental railroad. But in 1882, the Chinese Exclusion Act of 1882 barred Chinese immigration for 10 years and did now allow the Chinese already in the US to become citizens. Hope this answer helps.
