Keiko was visiting several Latin American cities over the summer and was made very uncomfortable by all the warm hugs and embraces she received when first meeting her host's friends. Keiko's discomfort was likely due to differences in between her native and host cultures:
a. sexual standards
b. courtship signals
c. display rules
d. manners

a. sexual standards

Explanation:

All over the world, the differences of cultures and tradition between individuals leads to distinct reaction when the two cultures clashes. For example, in a country where pork is not eaten, someone coming from that country would feal uncomfortable if heor she found herself in another country where that is the only meat served.

In the case of Keiko, her uncomfort might be as a result of the sexual standards displayed by people in her country which is quite different from her new cultural experience in the Latin american cities. Maybe, handshake is offered when opposite sexes are involved unlike the situation where she is being hugged by her host's friends.
