We kind of need to see the cartoon...
The president exercises a check over Congress through his power to veto bills, but Congress may override any veto (excluding the so-called "pocket veto") by a two-thirds majority in each house. When the two houses of Congress cannot agree on a date for adjournment, the president may settle the dispute.
Das Kapital and Communist Manifesto
Answer: Greek
I might add a little detail to this. Ever since the conquests of Alexander the Great in the 4th century BC, the Meditarranean world in general experienced "Hellenization." Or we might call it "Greekification." The <em>koine </em>(that is "common") Greek language became a common language throughout the lands where Alexander had cast his influence. When the Romans took over those lands, Greek remained a commonly spoken language. So Latin was the official language of the Roman empire and Romans themselves were native Latin speakers. But Greek had become the language of international commerce. When the New Testament was written in the early AD era, it was written in Greek for that reason.
So, in the Western Roman Empire, Latin remained spoken, but with Greek spoken alongside it. In the Eastern (or Byzantine) empire, Greek was predominantly spoken, while Latin remained known by educated persons, especially in government. And Greek did become the official language of the Byzantine Empire by the time of emperor Justinian. Justinian's famous law code, the <em>Corpus Iurus Civilis ("Body of Civil Law") </em>was published in both Greek and Latin editions.
The correct answer to your problem is yes!
