Rodney and elise are u. s. students studying abroad in italy. when they are introduced to their host families, the families kiss them on both cheeks. when rodney's host brother introduces himself and kisses rodney on both cheeks, rodney pulls back in surprise. where he is from, unless they are romantically involved, men do not kiss one another. this is an example of: a. culture shock
b. imperialism
c. ethnocentrism
d. xenocentrism

A) Culture shock

Explanation:

This is a clear example of what A) culture shock is: When someone is on a trip far from his homeland he experiences other cultures which have differents approaches to life (such as the kiss, or other´s like religion, food, dancing, clothing, sports etc.). When one encounters such different approaches there´s always a chance of being shoked by them (like our friend Rodney).

The answer clearly is not B) imperialism beacuse Rodney does not have any political or military attitude towards the italians. Neither is                      C) ethnocentrism because Rodney is not making a judgement towards the italian salute, he was simply suprised. And is not D) xenocentrism because  Rodney is not prefering the Italian way of saluting over the american way.
