In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Example Input: American Airlines Flight 11: FAA Awareness. Although the Boston Center air traffic controller realized at an early stage that there was something wrong with American 11, he did not immediately interpret the plane's failure to respond as a sign that it had been hijacked. At 8:14, when the flight failed to heed his instruction to climb to 35,000 feet, the controller repeatedly tried to raise the flight. He reached out to the pilot on the emergency frequency. Though there was no response, he kept trying to contact the aircraft. At 8:21, American 11 turned off its transponder, immediately degrading the information available about the aircraft. The controller told his supervisor that he thought something was seriously wrong with the plane, although neither suspected a hijacking. The supervisor instructed the controller to follow standard procedures for handling a "no radio" aircraft. The controller checked to see if American Airlines could establish communication with American 11. He became even more concerned as its route changed, moving into another sector's airspace. Controllers immediately began to move aircraft out of its path, and asked other aircraft in the vicinity to look for American 11. At 8:24:38, the following transmission came from American 11: American 11: We have some planes. Just stay quiet, and you'll be okay. We are returning to the airport. The controller only heard something unintelligible; he did not hear the specific words "we have some planes." The next transmission came seconds later: American 11: Nobody move. Everything will be okay. If you try to make any moves, you'll endanger yourself and the airplane. <sep>What were the first things done by America 11 that led the air traffic controller to notify his supervisor that something was wrong with the flight?<sep>There was no response
Example Output: No

Example Input: IBM opened a sprawling and sophisticated semiconductor factory here on Wednesday that cost more than $2.5 billion to build and equip, the largest single capital investment the company has ever made. The factory, which opens as the computer chip business is in a slump, is a costly and risky move for IBM. But it is also an expression of confidence by the company that it can remain a technology leader in the highly competitive global semiconductor industry, and a commitment that the best place to execute that strategy is in upstate New York. IBM is an exception among computer makers in that it still invests heavily in research to advance the design, manufacture and materials used in semiconductor chips. It is spending more than $500 million a year on semiconductor research and development. The factory will produce a wide range of specialized semiconductors used in everything from the largest mainframe computers to cell phones and video-game consoles. The new plant is part of IBM's push to gain a strong lead in chip-making beyond the personal computer business, where Intel and East Asian chip producers hold the advantage. "The core of our strategy is to lead in technology and attack the high-performance segments of the market," said John Kelly, senior vice president in charge of IBM's technology group. An advantage to having the semiconductor fabricating factory here, Kelly explained, was that it was very close to its research laboratories in nearby Westchester County, N.Y. To stay ahead in advanced chip technology, he said, moving innovations out of the labs and into the factory as fast as possible is crucial. "What we call the lab-to-fab time should be as close to zero as possible," Kelly said. "If our strategy were anything but to be on the leading edge, we'd have put the plant in Asia." The new factory, which will begin normal production early next year, will employ about 1,000 people. <sep>What does IBM's senior vice president in charge of their technology group, John Kelly, feel that the location of the new plant is so important?<sep>To increase the lab-to-fab time
Example Output: No

Example Input: Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important. Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it. <sep>In 1921, Chaim Wiezzman asked someone to assist him in raising money for Hebrew University of Jerusalem. Whom did he ask?<sep>Einstein
Example Output:
Yes
