Explanation:
The Roman Republic originated in the year 509 BC, when the last Etruscan king is deposed and the Senate takes over the functions of government.
After the monarchical experience, the Romans choose not to leave power in the hands of one individual. Therefore, they eliminated the figure of the king and all positions should be held by two or more people.
Thus, there was not the figure of one ruler, but two, called consuls. These had a one-year term and were to control each other.
During this time, Rome organized its institutions and made important military conquests that ensured it dominated the Mediterranean Sea.
the answer is: A cognitive psychologist enrolls undergraduate students for a computer-based study about the effect of mood on problem-solving behaviors.
Here the requirement for research with human subjects according to the Fed :
"Obtains information or biospecimens through intervention or interaction with the individual, and uses, studies, or analyzes the information or biospecimens; or Obtains, uses, studies, analyzes, or generates identifiable private information or identifiable biospecimens."
The experiment on this ption fulfill the criteria because:
- The experiment should use studies or analytics to obtain some sort of private information from the subjects. (such as their mood)
- The experiment should make some sort of intervention that can be used to measure its hypothesis. (in the case above, the researchers could put the subject under a certain level of stress before telling them to solve a set of problems)
- The researchers need to interact with the subject in a certain way. (since the researchers meet the undergraduate directly, it's considered as an interraction)
Nations form alliances in order to achieve goals that otherwise wouldn't be possible. For example, NATO, or the North Atlantic Treaty Organization, a coalition of countries in North America and Europe, agree to defend one another in case of attack from an outside party. This is clearly beneficial, because this intergovernmental support both makes an outside attack less probable, and if it occurs, easier to handle. Another example is NAFTA, or the North American Free Trade Agreement. Shared among Canada, the US, and Mexico, this alliance eradicated trade barriers within these countries. Another beneficial alliance, this agreement increases international trade due to lower costs and thus improves the international economy.
