Answer:
The correct answer is letter "C": gradual adjustment.
Step-by-step explanation:
Canadian anthropologist Kalervo Oberg (1901-1973) defined Cultural Shock as the process by which individuals culture crash against a new culture being introduced implying feelings such as anxiety, confusion, and impotence as a result of the cultural difference.
According to Oberg, there are four (4) stages in the Cultural Shock: the honeymoon; the crises or cultural shock phase; the gradual adjustment and recovery phase; the adaptation, resolution or acculturation phase.
In the gradual adjustment and recovery phase, the foreign culture starts to make sense and negative reaction to the unusual decreases. Problems do not end in this stage but individuals react positively to them. The foreign language is learned during this phase.
