Input: Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.
"What happens to static electricity if it is balanced?" is "All the positive charge is on the wool"?

OPTIONS:
- no
- yes
Output: no

Input: Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh").

Does the response "Saudi" correctly answer the question "Where did Mihdhar and Hazmi become experienced mujahideen?"?

Iwasaki's careful respect for the Long Beach program and its lawyers earned him the political capital he needed to complete his takeover in a matter of weeks. "The Long Beach program had strong support in the community so in a situation like that, one has to recognize that it's not like a takeover where I have all the answers and I know best," Iwasaki said. "The people in the community who are working there have the contacts and the knowledge that will allow service to continue." Things have gone less smoothly across town. There, Dudovitz, a longtime poverty lawyer and executive director of the San Fernando Valley's 36-year-old legal aid program, continues to struggle with his hostile takeover of the neighboring San Gabriel-Pomona Valleys service area one year after it was accomplished. On the bright side, Dudovitz has extended his respected program to clients in the San Gabriel-Pomona Valley, and he now operates on a much larger budget, $6.5 million last year. However, his clash with the old San Gabriel program resulted in litigation, bitter feelings and a mission that some say is not clearly focused on serving poor people. "It was a difficult situation that was probably mishandled by everyone," a longtime observer of the public interest community said of the San Fernando Valley-San Gabriel-Pomona Valley merger. "There are very few people who come out as the heroes. Personalities got involved when they shouldn't have. Things were said that caused bad feelings and couldn't be unsaid." Iwasaki's merger with the smaller, 48-year-old Long Beach program was friendly and fast, and no one - not even Long Beach board members - lost a job. When it was over, Iwasaki had $1 million more in federal dollars and two new offices. Long Beach clients regained services they had lost years ago when federal budget cuts and dwindling grants reduced the staff of 15 lawyers to five and cut immigration and consumer law programs. Iwasaki said, "[I judged the transition] better than I could have hoped for."

Question: "In the eyes of the public interest community, was Dudovitz's hostile takeover well-handled?"

Problem: The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

Question: "When did the artesian springs first appear?"

Answer: "Around 3000 b.c"
