[EX Q]: The ecclesiastical structure of the Roman Empire survived the movements and invasions in the west mostly intact, but the papacy was little regarded, and few of the western bishops looked to the bishop of Rome for religious or political leadership. Many of the popes prior to 750 were more concerned with Byzantine affairs and eastern theological controversies. The register, or archived copies of the letters, of Pope Gregory the Great (pope 590–604) survived, and of those more than 850 letters, the vast majority were concerned with affairs in Italy or Constantinople. The only part of Western Europe where the papacy had influence was Britain, where Gregory had sent the Gregorian mission in 597 to convert the Anglo-Saxons to Christianity. Irish missionaries were most active in Western Europe between the 5th and the 7th centuries, going first to England and Scotland and then on to the continent. Under such monks as Columba (d. 597) and Columbanus (d. 615), they founded monasteries, taught in Latin and Greek, and authored secular and religious works.
[EX A]: When did Gregory the Great become pope?

[EX Q]: While the Warsaw Pact was established as a balance of power or counterweight to NATO, there was no direct confrontation between them. Instead, the conflict was fought on an ideological basis. Both NATO and the Warsaw Pact led to the expansion of military forces and their integration into the respective blocs. The Warsaw Pact's largest military engagement was Warsaw Pact invasion of Czechoslovakia (with the participation of all Pact nations except Romania and Albania). The Pact failed to function when the Revolutions of 1989 spread through Eastern Europe, beginning with the Solidarity movement in Poland and its success in June 1989.
[EX A]: Which organization was in direct competition with the Warsaw Pact?

[EX Q]: The earth deity had power over the ghostly world, and it is believed that she was the deity behind the oracle. The older tales mentioned two dragons who were perhaps intentionally conflated. A female dragon named Delphyne (δελφύς, "womb"), who is obviously connected with Delphi and Apollo Delphinios, and a male serpent Typhon (τύφειν, "to smoke"), the adversary of Zeus in the Titanomachy, who the narrators confused with Python. Python was the good daemon (ἀγαθὸς δαίμων) of the temple as it appears in Minoan religion, but she was represented as a dragon, as often happens in Northern European folklore as well as in the East.
[EX A]:
Who was the adversary of Zeus in the titanomachy?
