In the majority culture of America,coughing,sweating,and diarrhea are symptoms of an illness.For some individuals of Mexican-American origin,however,these symptoms are a normal part of living.This is probably because Mexican-Americans:

A) have less efficient immune systems and are often ill.
B) consider these symptoms a part of normal living,not symptoms of ill health.
C) come from Mexico and coughing is normal and healthy there.
D) are usually in a lower socioeconomic group and are more likely to be sick.
