Marvin Wolfgang’s study of males born in Philadelphia in 1945 was an attempt to measure delinquency by following those males from their 10th birthday until they were 18. This is an example of what type of study?

Cohort Study

Explanation:

Cohort Study I'd a type of longitidunal study that follows a group of people over time to understand the relationship between some attribute shared by the group at the beginning nof the survey and the eventual outcome. That's same thing that Mavin is trying to do by understudying these group of individuals for some period of time to measure deliquency.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.
