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.

Answer: Which organization was in direct competition with the Warsaw Pact?


Question: In the early 1950s, Universal set up its own distribution company in France, and in the late 1960s, the company also started a production company in Paris, Universal Productions France S.A., although sometimes credited by the name of the distribution company, Universal Pictures France. Except for the two first films it produced, Claude Chabrol's Le scandale (English title The Champagne Murders) and Romain Gary's Les oiseaux vont mourir au Pérou (English title Birds in Peru), it was only involved in French or other European co-productions, the most noticeable ones being Louis Malle's Lacombe, Lucien, Bertrand Blier's Les Valseuses (English title Going Places), and Fred Zinnemann's The Day of the Jackal. It was only involved in approximately 20 French film productions. In the early 1970s, the unit was incorporated into the French Cinema International Corporation arm.

Answer: What was the name of the Universal production company based in Paris?


Question: According to conservation of energy, energy can neither be created (produced) nor destroyed by itself. It can only be transformed. The total inflow of energy into a system must equal the total outflow of energy from the system, plus the change in the energy contained within the system. Energy is subject to a strict global conservation law; that is, whenever one measures (or calculates) the total energy of a system of particles whose interactions do not depend explicitly on time, it is found that the total energy of the system always remains constant.

Answer:
According to what, energy can neither be created nor destroyed by itself?
