Answer choice E states that typically, the longer a drink exists in a particular place, then the more widely that beverage is used there. It would stand to reason then that the place where the beverage has existed for the longest (the originator) would be the place where the beverage is most widely used.
Answer choice A is incorrect because we do not support that Mate originated in Paraguay by stating that it is rare for there to be a great variety of a drink in a place unless it has been in use there for a long time. A long time does not mean the originator, nor does it tell us anything more to help determine that it was the first country to produce Mate.
