Answer:social learning
Explanation:
Social learning refers to how we learn from all those around us by closely watching their behaviour. Mostly we have people we look up to as our model and we are likely to model their behaviour after studying it carefully and we may find ourselves later doing what they did exactly as they were doing it.
However the behavior that we imitate depends on whether the behavior that we observed was reinforced or punished from our model. If the behaviour we observed was reinforced which means it hard a rewarding outcome ,it is likely that we will imitate that behavior so that we can also receive such reinforcement however if the behaviour was punished it is less likely that we will imitate it.
This is why Donna is trying to look at their mistakes and achievement because she wants to learnt from their mistakes and not repeat them and imitate those behavior that led to achievements.
Crude divorce rate is the ratio of the number of divorces to the average population in a given year. Divorce-marriage ratio is the ratio of the number of divorces to the number of marriages in a given year. Refined divorce rate is the ratio of divorces to the number of married women. Divorce rate is the general term for all of these ratios.
Thus, from the description, the answer is divorce-marriage ratio.

There were more than 1,100 passengers on board, 112 of whom lost their lives. Of those, 28 were Americans, but President Roosevelt was unfazed by the tragedy, declaring that no one was to “thoughtlessly or falsely talk of America sending its armies to European fields.” The United States would remain neutral.
