5.In your post, first propose a theory that could explain the following observation: Niamh has left her apartment and returned to it ten times in the last week. On seven

of those occasions, one of the books from her bookshelf was on the floor when she returned. Her other books were still on the bookshelf. All of the books were on the bookshelf before she left the apartment. After you have written your explanatory theory, provide an evaluation of it, giving consideration to all of the following criteria: testability, fruitfulness, scope, simplicity, and conservatism. (Note that you do not have to create a theory that is successful in meeting all these criteria, but if it has does have deficiencies in any of these areas then you should be able to identify and comment on them.) You must give reasons for any claims you make, and show a good understanding of all of these listed criteria.
