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".

Input: Consider Input: As noted above, the 9/11 plotters spent somewhere between $400,000 and $500,000 to plan and conduct their attack. The available evidence indicates that the 19 operatives were funded by al Qaeda, either through wire transfers or cash provided by KSM, which they carried into the United States or deposited in foreign accounts and accessed from this country. Our investigation has uncovered no credible evidence that any person in the United States gave the hijackers substantial financial assistance. Similarly, we have seen no evidence that any foreign government-or foreign government official-supplied any funding. We have found no evidence that the Hamburg cell members (Atta, Shehhi, Jarrah, and Binalshibh) received funds from al Qaeda before late 1999. It appears they supported themselves. KSM, Binalshibh, and another plot facilitator, Mustafa al Hawsawi, each received money, in some cases perhaps as much as $10,000, to perform their roles in the plot. After the Hamburg recruits joined the 9/11 conspiracy, al Qaeda began giving them money. Our knowledge of the funding during this period, before the operatives entered the United States, remains murky. According to KSM, the Hamburg cell members each received $5,000 to pay for their return to Germany from Afghanistan after they had been selected to join the plot, and they received additional funds for travel from Germany to the United States. Financial transactions of the plotters are discussed in more detail in chapter 7. Requirements for a Successful Attack As some of the core operatives prepared to leave for the United States, al Qaeda's leaders could have reflected on what they needed to be able to do in order to organize and conduct a complex international terrorist operation to inflict catastrophic harm. We believe such a list of requirements would have included leaders able to evaluate, approve, and supervise the planning and direction of the operation; communications sufficient to enable planning and direction of the operatives and those who would be helping them; a personnel system that could recruit candidates, vet them, indoctrinate them, and give them necessary training; an intelligence effort to gather required information and form assessments of enemy strengths and weaknesses; the ability to move people; and the ability to raise and move the necessary money. The information we have presented about the development of the planes operation shows how, by the spring and summer of 2000, al Qaeda was able to meet these requirements. By late May 2000, two operatives assigned to the planes operation were already in the United States. Three of the four Hamburg cell members would soon arrive. <sep>What time in 2000 does al Queada meet the requirements and what chapter can you find more details about financial transactions?<sep>Before May

Output: No

Input: Consider Input: MALS was formed here more than 30 years ago. Today, 14 staff attorneys, 26 office workers and 21 University of Memphis third- year law students work out of rented offices in the old Claridge Hotel building at 109 N. Main. Offices are spartan. There are no lush rugs or stylish furniture. The large table in the conference room is simple varnished wood. Offices are small and mostly plain, except for the eclectic mix of pop art, African statuary and neon that adorns litigation director Webb Brewer's space. Brewer, who has been at the agency 20 years, said there is a need for lawyers of all stripes to help with the problems of the poor. "The private bar could meet more of the need through pro bono work, but there are still cases that involve the systemic problems for low-income people that we would need to do," said Brewer. "The legal system marketplace just doesn't serve low-income people too well, except in fee-generat-ing type cases," Brewer said. "If a poor person gets run over by a bus, an attorney might take that case because they might be able to recover part of the damage award as attorney fees. But so many of the cases we handle have to do with basic rights and a decent life. There is just no profit motive." Larry Pivnick, law professor at the University of Memphis Law School and director of political programs at MALS, said Legal Services is a great learning laboratory for law students. "There are thousands and thousands of people who have problems that never get an opportunity to appear in court," Pivnick said. "Some people may not be particularly articulate. Courts have rules that clients don't always understand." Brewer said a major focus of the agency's work involves housing. "Although a lot of our work is grant-driven, we find that the lack of safe and decent affordable housing and the prevalence of predatory lending are the biggest problems in our client population," Brewer said, referring to clients such as James. <sep>What type of work is done by MALS?<sep>Medical work

Output: No

Input: Consider Input: Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter. <sep>How did Robert Boyle prove how sound waves travel?<sep>He placed a ticking clock in a jar and then removed the air from the jar.
Output: Yes
