The correct answer is d. none of the above. Chinese immigrants started to pour in the United States during the early 19th century. The Chinese were attracted to better job opportunities in the United States, and earned wages that helped them sustain their families in China. Local people hated them dearly because they are willing to work for lower wages. Since they were considered foreigners, they were excluded from joining trade unions that would have given them better rights. Almost all trade unions hated the Chinese too.
