A. tend to be younger at diagnosis.
B. show a more chronic and declining course.
C. show similar social and language deficits.

To compare children with autism and children with schizophrenia, we need to consider certain characteristics that differentiate these two disorders. Here is an analysis of the statements provided:

A. tend to be younger at diagnosis.
To determine whether children with schizophrenia are younger at diagnosis compared to children with autism, we can conduct research or consult reliable sources such as medical journals, textbooks, or reputable websites. These sources would provide data on average diagnosis age for each condition, allowing us to compare the findings.

B. show a more chronic and declining course.
To determine whether children with schizophrenia show a more chronic and declining course compared to children with autism, we would need to examine the clinical course of both disorders through research articles, longitudinal studies, and expert opinions. This would enable us to evaluate the trajectory and progression of symptoms over time for each disorder.

C. show similar social and language deficits.
To evaluate whether children with schizophrenia and children with autism show similar social and language deficits, we can review relevant studies that have compared the social and communication impairments in each disorder. These studies might use standardized assessment tools and observational measures to determine the similarities or differences in these domains.

D. show less intellectual impairment.
To investigate whether children with schizophrenia exhibit less intellectual impairment compared to children with autism, we can examine studies or resources that have assessed the cognitive functioning of individuals with each disorder. These sources may present data on various aspects of intellectual ability, such as IQ scores or cognitive assessments, allowing us to determine the extent of any differences.

In summary, to definitively answer the question, it is crucial to analyze relevant research, consult trusted sources, and consider expert opinions. Only through a comprehensive review of reputable information can we obtain accurate and reliable answers to make an informed comparison between children with autism and children with schizophrenia.
