problem_activity: Task
Researchers have noticed that the number of golf courses and the number of divorcees in the United States are strongly correlated and both have been increasing over the last several decades.  Can you conclude that the increasing number of golf courses is causing the number of divorcees to increase?
Either justify why a causation can be inferred, or explain what might account for the correlation other than a causal relation.
