Question

Disorganized speech and grossly disorganized behavior represent the ____ in schizophrenia.​

Answer 1

I believe the answer is: C.  a wide range of possible positive symptoms

Symptoms would be considered as a 'wide range' if that symptoms almost always happen even though there is some occurrences when they don't happen.
And the symptoms would be considered as positive if it affect thoughts, behaviors, or sensory perceptions of the patient.
