[Q]: I know that the answer to the question "Why is the Mozilla browser free?" is in "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.". Can you tell me what it is?

Please answer this: I know that the answer to the question "Ecuador is what kind of country in terms of its distance to the equator?" is in "During the Eocene (56 million years ago - 33.9 million years ago), the continents continued to drift toward their present positions. At the beginning of the period, Australia and Antarctica remained connected, and warm equatorial currents mixed with colder Antarctic waters, distributing the heat around the world and keeping global temperatures high. But when Australia split from the southern continent around 45 Ma, the warm equatorial currents were deflected away from Antarctica, and an isolated cold water channel developed between the two continents. The Antarctic region cooled down, and the ocean surrounding Antarctica began to freeze, sending cold water and ice floes north, reinforcing the cooling. The present pattern of ice ages began about 40 million years ago.[citation needed]". Can you tell me what it is?

Problem: I know that the answer to the question "Who was Kerry accused of making fun of?" is in "Kerry said that he had intended the remark as a jab at President Bush, and described the remarks as a "botched joke", having inadvertently left out the key word "us" (which would have been, "If you don't, you get us stuck in Iraq"), as well as leaving the phrase "just ask President Bush" off of the end of the sentence. In Kerry's prepared remarks, which he released during the ensuing media frenzy, the corresponding line was "... you end up getting us stuck in a war in Iraq. Just ask President Bush."

Can you tell me what it is?

A: American troops


Problem: Given the question: I know that the answer to the question "How is the system distinctive?" is in "Mexico City is served by the Sistema de Transporte Colectivo, a 225.9 km (140 mi) metro system, which is the largest in Latin America. The first portions were opened in 1969 and it has expanded to 12 lines with 195 stations. The metro is one of the busiest in the world transporting approximately 4.5 million people every day, surpassed only by subway lines in Moscow (7.5 million), Tokyo (5.9 million), and New York City (5.1 million). It is heavily subsidized, and has some of the lowest fares in the world, each trip costing 5.00 pesos from 05:00 am to midnight. Several stations display pre-Columbian artifacts and architecture that were discovered during the metro's construction.[citation needed] However, the metro covers less than half of the total urban area. The Metro stations are also differentiated by the use of icons and glyphs which were proposed for people who could not read. The specific icons were developed based on historical (characters, sites, pre-Hispanic motifs), linguistic, symbolic (glyphs) or location references and has being emulated in further transportations alternatives in the City and in other Mexican cities. Mexico City is the only city in the world to use the icon reference and has become a popular culture trademark for the city.". Can you tell me what it is?
