Question:
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. After reading the above, is "Boyle" the correct answer to the question "Which scientist demonstrated that sound waves cannot travel through empty space by placing a ticking clock in a sealed glass jar?"?

Answer:
yes

Question:
Sara wanted to play on a baseball team. She had never tried to swing a bat and hit a baseball before. Her Dad gave her a bat and together they went to the park to practice. Sara wondered if she could hit a ball. She wasn't sure if she would be any good. She really wanted to play on a team and wear a real uniform. She couldn't wait to get to the park and test out her bat. When Sara and her Dad reached the park, Sara grabbed the bat and stood a few steps away from her Dad. Sara waited as her Dad pitched the ball to her. Her heart was beating fast. She missed the first few pitches. She felt like quitting but kept trying. Soon she was hitting the ball very far. She was very happy and she couldn't wait to sign up for a real team. Her Dad was very proud of her for not giving up. After reading the above, is "She didn't want to really play" the correct answer to the question "Why do you think Sara missed the first few pitches?"?

Answer:
no

Question:
And William Martinez, 28, who cut his medical school studies short because he couldn't afford the $39,000 in loans after two years of graduate school and four years of college. Martinez works two jobs as a physician's assistant and supports his elderly parents and 8-year-old son. Uncommon Good has a 22-member board of doctors, lawyers and representatives of Christian groups and is recruiting mentors. One goal is to get the state Legislature to pass a law to provide loan forgiveness to medical professionals and lawyers who work with the poor. Mintie said she hopes her organization can be a national model for other professions. She is trying to bring legal aid services to the Inland Valley -- the closest legal aid office is in El Monte and represents 700,000 poor people throughout the San Fernando, San Gabriel and Inland valleys. "Unless the legal aid is in the community, you can't say you are serving the poor," Mintie said. Neal Dudovitz is the executive director of Neighborhood Legal Services of Los Angeles County, the legal aid office in El Monte. He sees attorneys new to poverty law leave all the time because they can't afford the salary with their law school debt. "She's really opened a lot of eyes in terms of having people understand how the educational debt is limiting and reducing the services that are available to low-income communities," Dudovitz said. "Nancy is light years ahead of the curve on this stuff. Very little is being done practically to solve it." Mintie, her colleagues say, could have made a lot of money in private practice. "She's very kind and pleasant," said Julius Thompson, 45, an attorney at Inner City Law Center and an Uncommon Good recipient. "But she's also a woman on a mission. When she sets her sights on something, she's a formidable force." After reading the above, is "18" the correct answer to the question "How old was William Martinez when he had his son?"?

Answer:
no

Question:
After the 1998 embassy bombings, the U.S. government tried to develop a clearer picture of Bin Laden's finances. A U.S. interagency group traveled to Saudi Arabia twice, in 1999 and 2000, to get information from the Saudis about their understanding of those finances. The group eventually concluded that the oft-repeated assertion that Bin Laden was funding al Qaeda from his personal fortune was in fact not true. The officials developed a new theory: al Qaeda was getting its money elsewhere, and the United States needed to focus on other sources of funding, such as charities, wealthy donors, and financial facilitators. Ultimately, although the intelligence community devoted more resources to the issue and produced somewhat more intelligence, it remained difficult to distinguish al Qaeda's financial transactions among the vast sums moving in the international financial system. The CIA was not able to find or disrupt al Qaeda's money flows. The NSC staff thought that one possible solution to these weaknesses in the intelligence community was to create an all-source terrorist-financing intelligence analysis center. Clarke pushed for the funding of such a center at Treasury, but neither Treasury nor the CIA was willing to commit the resources. Within the United States, various FBI field offices gathered intelligence on organizations suspected of raising funds for al Qaeda or other terrorist groups. By 9/11, FBI agents understood that there were extremist organizations operating within the United States supporting a global jihadist movement and with substantial connections to al Qaeda. The FBI operated a web of informants, conducted electronic surveillance, and had opened significant investigations in a number of field offices, including New York, Chicago, Detroit, San Diego, and Minneapolis. On a national level, however, the FBI never used the information to gain a systematic or strategic understanding of the nature and extent of al Qaeda fundraising. Treasury regulators, as well as U.S. financial institutions, were generally focused on finding and deterring or disrupting the vast flows of U.S. currency generated by drug trafficking and high-level international fraud. Large-scale scandals, such as the use of the Bank of New York by Russian money launderers to move millions of dollars out of Russia, captured the attention of the Department of the Treasury and of Congress. Before 9/11, Treasury did not consider terrorist financing important enough to mention in its national strategy for money laundering. After reading the above, is "Washington D.C" the correct answer to the question "Where were field offices opened to investigate al Qaeda funding?"?

Answer:
no
