Answer:
There is a high positive correlation between sleep and exam performance.
Explanation:
The concept of correlation indicates an association, that is to say, it is used for measuring how much two variables relate to each other. The 3 results of a correlational study are positive, negative, and no correlation. A positive correlation takes place between 2 variables that can increase or decrease together. In this case, the more students sleep, the better they performed at their exams.

The normative relationships and patterns of interaction that guide group behavior in particular settings is known as Social Structure .
<h2>What is social structure ?</h2>
Social structure is the patterned social arrangements in society that are both emergent from and determined of the actions of individuals. 
Studies of social structure try to explain things like trends in inequality and integration. Sociologists examine institutions, social categories (like age groups) or rates (like crime or birth rates) in the study of these phenomena.
This method, often known as formal sociology, does not make a direct reference to personal choices or social interactions. Because the analysis is too abstract at this level, social structure research is not regarded as a behavioral science.

Answer:
 A. Danube
Explanation:
The river shown by number 1 is the Volga.
The river shown by number 2 is Ob.
Rover shown by number 3 is Lena.
<u>These three rivers all flow through Russia. The Danube is not shown in the picture – it does not pass through Russia at all, and it is Russia and its rivers that are depicted in the image.</u>
The Danube flows through the European countries located West of Russia. It starts in Germany, going through Austria, Slovakia, many Balkan countries, Moldova and Ukranie. In the end, it goes in the Black Sea. It is the second-longest European river, after the Volga, and it flows for 2850km.
