The artist who drew this cartoon agreed with which of the following ideas? Chinese immigrants are a threat to American workers. It is unfair to single out Chinese immigrants for restriction. It is risky to accept immigrants who are Communists. American industry will be crippled without Chinese laborers.
Assuming that this is referring to the same cartoon that was posted before with this question, the best option is "American industry will be crippled without Chinese laborers" since it shows railroads failing.
