Question: 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.
Is there an answer to this question: What was the name of the Albanian revolutionary movement which the Warsaw Pact failed to suppress?

Answer: unanswerable


Question: The region covers an area of 1,579 square kilometres (610 sq mi). The population density is 5,177 inhabitants per square kilometre (13,410/sq mi), more than ten times that of any other British region. In terms of population, London is the 19th largest city and the 18th largest metropolitan region in the world. As of 2014[update], London has the largest number of billionaires (British Pound Sterling) in the world, with 72 residing in the city. London ranks as one of the most expensive cities in the world, alongside Tokyo and Moscow.
Is there an answer to this question: With which two other cities is London named one of the most expensive in the world?

Answer: Tokyo and Moscow


Question: The islands are at relatively low altitudes, with central Ireland and southern Great Britain particularly low lying: the lowest point in the islands is Holme, Cambridgeshire at −2.75 m (−9.02 ft). The Scottish Highlands in the northern part of Great Britain are mountainous, with Ben Nevis being the highest point on the islands at 1,343 m (4,406 ft). Other mountainous areas include Wales and parts of Ireland, however only seven peaks in these areas reach above 1,000 m (3,281 ft). Lakes on the islands are generally not large, although Lough Neagh in Northern Ireland is an exception, covering 150 square miles (390 km2).[citation needed] The largest freshwater body in Great Britain (by area) is Loch Lomond at 27.5 square miles (71 km2), and Loch Ness, by volume whilst Loch Morar is the deepest freshwater body in the British Isles, with a maximum depth of 310 m (1,017 ft). There are a number of major rivers within the British Isles. The longest is the Shannon in Ireland at 224 mi (360 km).[citation needed] The river Severn at 220 mi (354 km)[citation needed] is the longest in Great Britain. The isles have a temperate marine climate. The North Atlantic Drift ("Gulf Stream") which flows from the Gulf of Mexico brings with it significant moisture and raises temperatures 11 °C (20 °F) above the global average for the islands' latitudes. Winters are cool and wet, with summers mild and also wet. Most Atlantic depressions pass to the north of the islands, combined with the general westerly circulation and interactions with the landmass, this imposes an east-west variation in climate.
Is there an answer to this question: At 33.5 square miles, what is the largest freshwater body in Great Britain?

Answer: unanswerable


Question: The medical treatment of infectious diseases falls into the medical field of Infectious Disease and in some cases the study of propagation pertains to the field of Epidemiology. Generally, infections are initially diagnosed by primary care physicians or internal medicine specialists. For example, an "uncomplicated" pneumonia will generally be treated by the internist or the pulmonologist (lung physician). The work of the infectious diseases specialist therefore entails working with both patients and general practitioners, as well as laboratory scientists, immunologists, bacteriologists and other specialists.
Is there an answer to this question: Disease propagation can fall under the purview of what field of study?

Answer:
Epidemiology
