Question

the origins of segregation legislation is powerless to eliminate racial instincts or to abolish distinctions based upon physical differences.... if the civil and political rights of both races be equal, one cannot be inferior to the other civilly or politically. if one race be inferior to the other socially, the constitution of the united states cannot put them upon the same plane. what is the main purpose of this passage? to criticize louisiana for its segregation of railroad cars to argue against those who oppose segregation to defend segregation as an acceptable practice to deny that legal segregation is necessary

Explanation:

The passage states that legislation can't eliminate racial instincts or physical - based distinctions, and if one race is socially inferior, the Constitution can't put them on the same plane. This is defending segregation by suggesting that it's a result of natural racial differences and that the Constitution can't override social inferiority, so the main purpose is to defend segregation as acceptable. The first option is incorrect as the passage isn't criticizing Louisiana. The second option is wrong as it's not arguing against anti - segregationists. The fourth option is incorrect as it's not denying the necessity of legal segregation.

Answer:

C. To defend segregation as an acceptable practice
