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: "Where did the people live and what happened to the landscape over the years?"

Answer: "New lakes discovered"
Answer: no

Problem: 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.

Question: "What line, running north to south, passes through Greenwich, England and is also at the equator?"

Answer: "Zero longitude"
Answer: yes

Problem: LONDON, England (CNN) -- The most eagerly anticipated animated film this year hits big screens this weekend, as "The Simpsons Movie" opens worldwide. The Screening Room spoke to creator Matt Groening and writer Al Jean in London about everyone's favorite two-dimensional yellow family. Simpsons supremo Matt Groening with his creations at the film's premiere in Springfield, Vermont Matt Groening told the Screening Room that fans had driven the demand for the movie. "We've had fans clamoring for a movie for the past 18 years," he said. The film has taken four years to come to fruition, as writer Al Jean explained. "What really held us up for a long time was to have enough people to do the show and the movie," he said. "We talked for a while about doing the movie after the show is done, but the show is never done! So it really started in earnest in 2003, when we started working on this story that became the movie." Technology has also played its part. Jean continued, "The technology to do this film really wasn't even around five years ago. For example, there was this joke I once pitched and David Silverman, the director, started drawing and as I was pitching it, it went into the film and it was cut a day later. To go from pitch to cut in two days is pretty impressive." Its creators hope that "The Simpsons Movie" will both satisfy long-term fans and bring Homer and Marge's family to a new audience. Groening told the Screening Room, "This movie is designed to both honor the people who have loved the show all this time, so there's lots of little details for them in the movie, little characters and stuff who they know and love, but we also want people who don't know the family to not be completely confused. It is a complete movie experience, but again, we have a lot of little details that only the really, true die-hard fans are going to get." And fans can expect to be entertained by plenty of cartoon mishaps. Groening said, "When you see somebody fall off the roof in a live-action film, it's funny -- we all love it. But it's not as funny as when Homer falls off the roof.

Question: "Who was quoted saying, "We've had fans clamoring for a movie for the past 18 years."?"
