Essays / Essay for my undergrad elective - Empirical vs logical validity [3]

I have to write an essay for my undergrad elective and I'm confused. We are given a list of essay questions to choose from which are in the form of "Present two views in support of... and two views against... Then, present your own informed view on their logical and empirical validity."

I'm not exactly sure what this means (i.e. logical vs empirical validity). If somebody can provide an explanation and possibly an example, that would be much appreciated.
