Input: Article: The old oracles in Delphi seem to be connected with a local tradition of the priesthood, and there is not clear evidence that a kind of inspiration-prophecy existed in the temple. This led some scholars to the conclusion that Pythia carried on the rituals in a consistent procedure through many centuries, according to the local tradition. In that regard, the mythical seeress Sibyl of Anatolian origin, with her ecstatic art, looks unrelated to the oracle itself. However, the Greek tradition is referring to the existence of vapours and chewing of laurel-leaves, which seem to be confirmed by recent studies.

Now answer this question: Who did scholars beieve carried on the rituals in a consistent procedure?

Output: Pythia

Input: Article: In the Roman Church, universal positive ecclesiastical laws, based upon either immutable divine and natural law, or changeable circumstantial and merely positive law, derive formal authority and promulgation from the office of pope, who as Supreme Pontiff possesses the totality of legislative, executive, and judicial power in his person. The actual subject material of the canons is not just doctrinal or moral in nature, but all-encompassing of the human condition.

Now answer this question: What is given to the universal positive law of the Roman Catholic Church by its leader?

Output: formal authority and promulgation

Input: Article: The Eastern Roman Empire – today conventionally named the Byzantine Empire, a name not in use during its own time – became increasingly influenced by Greek culture after the 7th century, when Emperor Heraclius (AD 575 - 641) decided to make Greek the empire's official language. Certainly from then on, but likely earlier, the Roman and Greek cultures were virtually fused into a single Greco-Roman world. Although the Latin West recognized the Eastern Empire's claim to the Roman legacy for several centuries, after Pope Leo III crowned Charlemagne, king of the Franks, as the "Roman Emperor" on 25 December 800, an act which eventually led to the formation of the Holy Roman Empire, the Latin West started to favour the Franks and began to refer to the Eastern Roman Empire largely as the Empire of the Greeks (Imperium Graecorum).

Now answer this question: What decision did he make that influenced the culture in an attempt to make things more homogeneous ?

Output:
decided to make Greek the empire's official language.
