Answer:Carol had to adjust to CULTURAL differences
Explanation:
Cultural differences refers to doffrences in beliefs, behaviours, languages, practices and customs amongst the individuals of different ethnic ,race or national origin.
Sometimes cultural differences also occurs due to age differences of educational background and also the places from which we were raised such as between individuals raised in rural areas and those raised in urban areas.
All these differences if not embraced by individuals from different groups they may lead to cultural clash.
Carol is now in a foreign country where she doesn't share the same national origin with the people so it very likely that there are so many cultural differences that exist; she may need to adapt to these new values and beliefs as she learns and understand them.
