While doing research on crime, professor middler notes that crime creates jobs in law enforcement and related careers. he also notices that crime reinforces community norms when criminals are caught and punished. professor middler has probably adopted a approach to the study of crime?

The answer is structural functionalism.  

I hope this helps.

Ifound the exercise on the internet. attached is the list mentioned above.in order for a compound to be considered optically active it can't have any axis or plan of symmetry. the molecule  shouldn't also  be superimposable on its mirror image.with such considerations, the compounds that are optically active are: -third compound on the first image is optically active; -second and third compound from the second image are optically actives.
