Input: How can you describe your location? You might use a familiar system. You might say, 'I live at 1234 Main Street, Springfield, Ohio.' You could also say, 'I live right behind the Elementary School.' This method uses the school as a point of reference. Another example is, I am at the corner of Maple Street and Main Street. Both streets may be a good reference for anyone living in your town. Scientists must be able to pinpoint a feature they are studying. Scientists use a special system to describe locations. They use latitude and longitude as a reference. Lines of latitude and longitude form a grid. You may have used a grid system while doing graphing. This grid is centered on a reference point. Zero latitude is the equator. Lines of latitude run east to west. They divide the Earth from North to South. Lines of longitude run from north to south. They divide the Earth from East to West. Zero longitude runs through Greenwich, England. You may have heard the term, Greenwich Mean Time, or GMT. The system of latitude and longitude works well for objects that do not move.

Does the response "Latitude is two dimensional and longitude is three dimensional" correctly answer the question "How do lines of longitude and latitude differ from one and another?"?

- no

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.

Question: "How do astronauts hear each other?"

OPTIONS:
- no
- yes

Answer: "Boyle carries them with his empty jar."

Response: no

Little is known of the earliest Stone Age inhabitants of Europe's southwestern extremity. The ancient Greeks called them the Cynetes (or Cunetes). Whatever their origins, their culture evolved under the pressure and influence of foreign forces. Among the many invading armies that settled here and contributed to nascent Portuguese culture were Phoenicians, who settled in the area around 1,000 b.c., followed by the Celts, Iberians, Greeks, and Carthaginians. But it was the Romans, who arrived late in the third century b.c., who most greatly influenced all of Iberia. They built towns, industries, roads, and bridges, developed agriculture, and bequeathed the Latin language, of which Portuguese is a direct descendant. The Romans named the southwestern province of the peninsula Lusitania, oddly enough for one of the Celtiberian tribes they defeated, and by the third century a.d. had introduced Christianity. By the beginning of the fourth century the Algarve had a bishop in place, based in Faro. But Rome had already fallen into decay, and soon hordes of northern tribesmen took over the empire. The Algarve fell to the Visigoths in the mid-fifth century. Under Moorish Rule In a.d. 711, the Moors brought powerful armies from North Africa and launched a devastating attack on the Iberian peninsula, conquering much of what would become Spain and Portugal. They imposed Islam and left an indelible influence on the countryside and the population of the Algarve. The Moorish legacy can still be seen in the form of wells and waterwheels, squat white houses, the dark complexions of the people, and in the very name given the regiontaken from Al-Gharb, which means "country of the west" (when the Moors conquered the territory, it was the most westerly in the known world). The Moors governed their Iberian kingdoms from across the border in Seville, but the Algarve had its own regional capital and huge, invulnerable fortress. The capital was Chelb (or Xelb), and it was bigger and better defended than Lisbon. Today the town, known as Silves, is a provincial outpost whose only besiegers are busloads of tourists who climb the narrow streets up to the old Moorish ramparts.

Question: "What did the Greeks call the early Stone Age inhabitants?"

Response: "Chelb"

Still untaken are several steps that required goodwill from local bar associations and others who had opposed the combination. "[I am] not a fan of Neal's," admitted John Peck, a former board member of the San Gabriel-Pomona Valley program and a Pasadena Bar Association board member. Peck says bad feelings still linger among Ailies of the old program who feel left out. "They really screwed us. We had a good program," Peck said. An observer familiar with the reconfiguration debate who requested anonymity wondered why Dudovitz had not spent more time mending fences. "He ought to be bending over backwards for reconciliation, but if you want to do impact work and people in the San Gabriel Valley want direct services, you have to accommodate that or change your approach," the observer said. "Neal would never consider doing that." More than a year after he officially incorporated the San Gabriel-Pomona Valley, Dudovitz had not placed a local resident on the board of Neighborhood Legal Services or made the rounds of the private legal community to recruit the volunteer lawyers. "Our emphasis has been on having our potential clients know about us and deliver services to them," Dudovitz said. "We have done that spectacularly." He did not hire any of the old program's nine lawyers and has yet to permanently place any of his 18 new hires in the San Gabriel-Pomona Valley. The lack of a legal aid presence in Pomona prompted the bar association and court officials to start their own once-monthly family law clinic. After learning of the effort, Dudovitz sent personnel to staff the clinic for three hours per week and is helping to write a grant application to fund a self-help kiosk for Pomona patterned on the center he pioneered in Van Nuys. The help, although late, has earned Dudovitz some appreciation. "There has been a transition and [the clinic] has helped to fill some void," said Deni Butler, administrator for the Eastern District Superior Court. "But we are working together quite nicely contrary to what the other side issue is." Scott Wheeler, president of the Eastern Bar Association of Los Angeles and an ally of the old program, said he mobilized his 200 members to staff the clinic after watching the ranks of unserved poor grow over the past year.

Question: "According to an observer, what would Neal never consider doing?"

Response: "Build fences for neighbors"
