Take schizophrenia as an example-

Common symptoms are visual and auditory hallucinations.

In, let's say, America, someone experiencing those symptoms is considered abnormal, or ill, and we apply a clinical lens to it, because culturally, those people are labeled as "crazy". We have a medical diagnosis for that.

Now pretend we are in an indigenous tribe somewhere, and culturally, shamans are a large part of their way of life. It is believed that those shamans see and hear messages from the universe or gods. Culturally, what we consider hallucinations, they are considered a blessing. This person will be respected. Schizophrenia doesn't exist to them. Therefore, the symptoms aren't even symptoms.

The cultural norms between the United States and a remote tribe somewhere are very different, so how someone with auditory and visual hallucinations will be treated will be very different.

Hopefully, this makes some sense. I think this is what they are kind of trying to say, or at least the way I interpreted it. The way this question is worded is very strange.
