Of the following items, which form of currency is the most durable and portable?
rice
cattle
olive oil
tulip bulbs
in the early 1800s, which of the following was not authorized to issue currency?
cities
stores
churches counties

The items which are most durable as a form of currency (and are also the most portable) would most likely be olive oil. Olive oil has a long shelf time and doesn't require nor take up much space. It is very precious in lower quantities and is therefore a good currency. 

In the early 1800s, stores weren't authorized to issue currency themselves. 

Any answer choices that would me answer your question?
