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:
Today, most commercial web browsers are paid by search engine companies to make their engine default, or to include them as another option. For example, Google pays Mozilla, the maker of Firefox, to make Google Search the default search engine in Firefox. Mozilla makes enough money from this deal that it does not need to charge users for Firefox. In addition, Google Search is also (as one would expect) the default search engine in Google Chrome. Users searching for websites or items on the Internet would be led to Google's search results page, increasing ad revenue and which funds development at Google and of Google Chrome.
answer:
Which company pays Firefox to make their search engine the default on their browser?
