Question: South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years.

Question: Tito was notable for pursuing a foreign policy of neutrality during the Cold War and for establishing close ties with developing countries. Tito's strong belief in self-determination caused early rift with Stalin and consequently, the Eastern Bloc. His public speeches often reiterated that policy of neutrality and cooperation with all countries would be natural as long as these countries did not use their influence to pressure Yugoslavia to take sides. Relations with the United States and Western European nations were generally cordial.

Question: In July 2015, Eton accidentally sent emails to 400 prospective students, offering them conditional entrance to the school in September 2017. The email was intended for nine students, but an IT glitch caused the email to be sent to 400 additional families, who didn't necessarily have a place. In response, the school issued the following statement: "This error was discovered within minutes and each family was immediately contacted to notify them that it should be disregarded and to apologise. We take this type of incident very seriously indeed and so a thorough investigation, overseen by the headmaster Tony Little and led by the tutor for admissions, is being carried out to find out exactly what went wrong and ensure it cannot happen again. Eton College offers its sincere apologies to those boys concerned and their families. We deeply regret the confusion and upset this must have caused."

Question: The War of the Austrian Succession had seen the belligerents aligned on a time-honoured basis. France’s traditional enemies, Great Britain and Austria, had coalesced just as they had done against Louis XIV. Prussia, the leading anti-Austrian state in Germany, had been supported by France. Neither group, however, found much reason to be satisfied with its partnership: British subsidies to Austria had produced nothing of much help to the British, while the British military effort had not saved Silesia for Austria. Prussia, having secured Silesia, had come to terms with Austria in disregard of French interests. Even so, France had concluded a defensive alliance with Prussia in 1747, and the maintenance of the Anglo-Austrian alignment after 1748 was deemed essential by the Duke of Newcastle, British secretary of state in the ministry of his brother Henry Pelham. The collapse of that system and the aligning of France with Austria and of Great Britain with Prussia constituted what is known as the “diplomatic revolution” or the “reversal of alliances.”
Try to answer this question if possible: Who was the traditional partner with Great Britain at the beginning of the conflict?
Answer:
Great Britain and Austria, had coalesced
