Input: Consider Input: An additional extension to MPEG-2 is named MPEG-2.5 audio, as MPEG-3 already had a different meaning. This extension was developed at Fraunhofer IIS, the registered MP3 patent holders. Like MPEG-2, MPEG-2.5 adds new sampling rates exactly half of that previously possible with MPEG-2. It thus widens the scope of MP3 to include human speech and other applications requiring only 25% of the frequency reproduction possible with MPEG-1. While not an ISO recognized standard, MPEG-2.5 is widely supported by both inexpensive and brand name digital audio players as well as computer software based MP3 encoders and decoders. A sample rate comparison between MPEG-1, 2 and 2.5 is given further down. MPEG-2.5 was not developed by MPEG and was never approved as an international standard. MPEG-2.5 is thus an unofficial or proprietary extension to the MP3 format.

Output: As MPEG-3 had a different meaning, what was the name given to the extension of MPEG-2?

Input: Consider Input: Following the 11 September 2001 attacks, former President of Pakistan Pervez Musharraf sided with the U.S. against the Taliban government in Afghanistan after an ultimatum by then U.S. President George W. Bush. Musharraf agreed to give the U.S. the use of three airbases for Operation Enduring Freedom. United States Secretary of State Colin Powell and other U.S. administration officials met with Musharraf. On 19 September 2001, Musharraf addressed the people of Pakistan and stated that, while he opposed military tactics against the Taliban, Pakistan risked being endangered by an alliance of India and the U.S. if it did not cooperate. In 2006, Musharraf testified that this stance was pressured by threats from the U.S., and revealed in his memoirs that he had "war-gamed" the United States as an adversary and decided that it would end in a loss for Pakistan.

Output: Which Pakistan president supported the US attacking the Taliban?
