Dr. Croteau explains to students in his methodology class that when they are using a mixed design, they are essentially using a(n) factorial design with multiple independent variables.
Methodology is studying the methods used in field and the theories or principles behind them, so that you can develop a approach which matches your requirements.
Mixed design is an approach in which the researcher have to examines both the potential differences between two or more separate groups of participants and also the individual changes over time.
Factorial design is necessary  when interactions are there to avoid misleading conclusions. They allow the effects of a factor to be estimated at several levels of a factor, that can yield a conclusion that are valid over a range of experimental conditions.

Second, to be a judicial power it would involve a trial to find out if someone broke the established rules and requires the application of the pertinent laws according to his or her behavior. For it to be independent it would require him to fight for a cause without the support of an organization. therefore, democracy is the correct answer.
