Answer:
prisoners
Explanation:
Prisoners have been popular victims(research subjects) of illegal research in the past and so laws have been put in place to prevent this.
Prisoners are classified as "vulnerable" under federal regulations that regulate research with prisoners. This is because their informed consent and voluntary decision to participate in any research brought before them is somewhat compromised. The health and human services(HHS) in addition to other regulations have added additional requirements for research on prisoners such as the requirement of a prisoner or prisoner representative in the IRB.
The correct answer would be, hierarchical system.
Sabrina made effective use of hierarchical system.
Explanation:
When people arrange things physically or in their minds in an order from above to lower to lower to above, this is called as making hierarchical system.
Hierarchies are seen in organizations where there is a top management which is then goes down to managerial level, which further divides into supervisors and then employees of the company which represents the lowest in hierarchy.
Similarly hierarchical systems can be found anywhere. When Sabrina remembered the things she had to buy by remembering them from generalized top category to a lower more narrowed one, she was actually made an effective use of hierarchical system.
