iPhone - Text Displayed from Database when Buttons Pushed

I am new to the iPhone. I am writing an App that will display text information based on the sequence someone presses on a set of buttons. There are five (5) Tables that each have about sixty (60) responses that are about the size of the sample below: There will be a total of maybe three hundred (300) unique responses. I want to be able to update these 300 unique answers each 6 months or so in an updated version. What is the best storage and retrieval method? SQlite?, Core Data? some other method?

You could do a plist or series of plists. 300 may not really warrant a database. And plists would be very simple to update.
