How can nativism best be described?

CHOICES:
A) Loyalty to old immigrants and discrimination against new immigrants.
B) Loyalty to any immigrants that adapted to the American way of life.
C) Discrimination against any immigrant from Asia.
D) Discrimination against immigrants who practiced Protestantism.

ANSWER:
A) Loyalty to old immigrants and discrimination against new immigrants.

Nativism refers to the political policy that favors the interests of natives or current inhabitants within a country against those of new immigrants. Based on this definition we can conclude that "Loyalty to old immigrants and discrimination against new immigrants." is the best description of nativism. We can understand the preference for the terms "old immigrants" rather than natives because in most scenarios nativism refers to the "patriot" population of a country rather than the original people of said country, take the U.S.A for example, when we talk about natives we aren't referring to the indigenous population as much as we are to the old immigrants taken as the forefathers of the United States. All the other answers are incorrect because nativism expresses a certain aversion towards newer immigrants so we can't say that it means, "Loyalty to any immigrants that adapted to the American way of life." There is also no specific discrimination described within nativism towards Asians or Protestants so the best option really is "Loyalty to old immigrants and discrimination against new immigrants.".
