Answer and Explanation:
1. Nellie Bly affirms that the mentally ill are mistreated, abused and that there is no type of commitment from the employees in relation to the patients, since they are not concerned with their well-being, nor with their correct treatment, since the employees only care about testing new equipment, not caring about patients.
