Answer:
Ethnocentric.
Explanation:
As the exercise suggests, Rhett is trying to avoid having an ethnocentric approach to business. This approach consists in, basically, adapting the branch of a company to resemble the parent country, even if it is in a very different country in terms of social, cultural or economics differences. This is seen when Rhett tries to adapt onto this differences instead of forcing the "American way" on them, hence his attitude against an ethnocentric approach.
