An interesting distinction here: jkaptur says that an educated citizen "can", which I interpret as meaning that such a citizen possesses the ability to do or figure out how to do the thing, independently of whether they currently know it. This is different than your "must", which takes it a step further and defines things everyone should know. I think an educated citizen should know how to, if they so desired, have an informed opinion on anything, whether it's current emission standards or the NSA's definition of collecting information. That citizen should be able to research and learn how to change the oil on their car, or to learn how a 4-stroke engine works.
