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: The National Security Act of 1947 created the position of Director of Central Intelligence (DCI). Independent from the departments of Defense, State, Justice, and other policy departments, the DCI heads the U.S.intelligence community and provides intelligence to federal entities. The sole element of the intelligence community independent from a cabinet agency is the CIA. As an independent agency, it collects, analyzes, and disseminates intelligence from all sources. The CIA's number one customer is the president of the United States, who also has the authority to direct it to conduct covert operations. Although covert actions represent a very small fraction of the Agency's entire budget, these operations have at times been controversial and over time have dominated the public's perception of the CIA. The DCI is confirmed by the Senate but is not technically a member of the president's cabinet. The director's power under federal law over the loose, confederated "intelligence community" is limited. He or she states the community's priorities and coordinates development of intelligence agency budget requests for submission to Congress. This responsibility gives many the false impression that the DCI has line authority over the heads of these agencies and has the power to shift resources within these budgets as the need arises. Neither is true. In fact, the DCI's real authority has been directly proportional to his personal closeness to the president, which has waxed and waned over the years, and to others in government, especially the secretary of defense. Intelligence agencies under the Department of Defense account for approximately 80 percent of all U.S. spending for intelligence, including some that supports a national customer base and some that supports specific Defense Department or military service needs. As they are housed in the Defense Department, these agencies are keenly attentive to the military's strategic and tactical requirements. <sep>Who coordinates development of intelligence agency budget requests for submission to Congress?<sep>Director of Central Intelligence
Example Output: Yes

Example Input: When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though. <sep>What do humans have that plants don't have?<sep>Immune systems
Example Output: Yes

Example Input: Although  Bin Laden, Atef, and KSM initially contemplated using established al Qaeda members to execute the planes operation, the late 1999 arrival in Kandahar of four aspiring jihadists from Germany suddenly presented a more attractive alternative. The Hamburg group shared the anti-U.S. fervor of the other candidates for the operation, but added the enormous advantages of fluency in English and familiarity with life in the West, based on years that each member of the group had spent living in Germany. Not surprisingly, Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah would all become key players in the 9/11 conspiracy. Mohamed Atta was born on September 1, 1968, in Kafr el Sheikh, Egypt, to a middle-class family headed by his father, an attorney. After graduating from Cairo University with a degree in architectural engineering in 1990, Atta worked as an urban planner in Cairo for a couple of years. In the fall of 1991, he asked a German family he had met in Cairo to help him continue his education in Germany. They suggested he come to Hamburg and invited him to live with them there, at least initially. After completing a course in German, Atta traveled to Germany for the first time in July 1992. He resided briefly in Stuttgart and then, in the fall of 1992, moved to Hamburg to live with his host family. After enrolling at the University of Hamburg, he promptly transferred into the city engineering and planning course at the Technical University of Hamburg-Harburg, where he would remain registered as a student until the fall of 1999. He appears to have applied himself fairly seriously to his studies (at least in comparison to his jihadist friends) and actually received his degree shortly before traveling to Afghanistan. In school, Atta came across as very intelligent and reasonably pleasant, with an excellent command of the German language. When Atta arrived in Germany, he appeared religious, but not fanatically so. This would change, especially as his tendency to assert leadership became increasingly pronounced. According to Binalshibh, as early as 1995 Atta sought to organize a Muslim student association in Hamburg. In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians. Atta proved a poor bridge, however, because of his abrasive and increasingly dogmatic personality. But among those who shared his beliefs, Atta stood out as a decisionmaker. <sep>How many years after graduating Cairo university passed before Mohamed Atta traveled to Germany<sep>1
Example Output:
No
