Step-by-step explanation:
A positive correlation means that as one variable increases, the other variable also increases. In terms of health benefits, a positive correlation would indicate that as the variable under investigation increases, there are positive health benefits associated with it. So, if the question is asking if exercise and many drugs are similar in terms of their benefits, we would need to consider if there is a positive correlation between exercise and the benefits it provides, as well as if there is a positive correlation between drugs and the benefits they provide.
