Answer: Experimental Method
Explanation:
The field of psychology has several research methods for the study of human behavior and its different forms. There is what is called experimental psychology, which expresses that psychological phenomena can be studied through the experimental method through observation, manipulation, and recording of the variables that affect the object of study.
The experimental method expresses that one or several variables are manipulated to determine their effect on an independent variable. In this case, rap music is set to see how it influences aggressive behavior and is analyzed because this type of music may have a certain relationship with the behavior.
In the experimental method, humans and animals are used to know the behavior that an individual may have when exposed to other variables that may interfere with their behavior. This type of experiment is usually done more in animals than in people because researchers can dispose of them at any time and in turn have more control. Besides, some experiments cannot be carried out in human beings due to ethical issues since if they are carried out they could put the person's health at stake.
The answer to this question is: Valid
For example, let's say that a researcher wants to study the psychology of motivation as a variable.
In this case, motivation does not possess a measurable standard that could be used as data, so the researcher could only predict thte amount of motivation through the amount of job done (but this data is reliable because motivation is only on of the many factors that may influenced it)

Answer:
In the United States, the two major layers of government are at the state and national levels. This system, where more than one layer of government has jurisdiction over the same territory, is called federalism. Although it seems natural to US citizens that government is divided into multiple layers, in fact, there are only 15 federal republics in the world.
In the United States, the federalist system emerged because the states evolved from separate colonies, which had diverse populations and different needs. The Framers of the Constitution envisioned that state governments, not the national government, would be the main unit of government for citizens on a day-to-day basis.
