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.

Problem: Also on Feb. 12, a week before the ice dancing finals, Tokhtakhounov told Anissina's mother in a telephone call that the Russian federation official "had called me from America" to assure that "we are going to make" Anissina "an Olympic champion." He told her that the Russian skating federation official "will help -- he has two or three judges." On or about March 7, in a conversation between Tokhtakhounov and Anissina, she said she would have won the event without his assistance because the Russian judge did not vote for her and her partner. She also apologized for not calling to thank him earlier, but that Gailhaguet had forbidden her. She told Tokhtakhounov that she knew the FBI had interviewed Gailhaguet because of information that Tokhtakhounov "was involved with the results" of the ice dancing. He assured her that it was nonsense, but that Gailhaguet "knows my name very well -- he tried to help me, and later he made stuff up to scare you so you would not connect me to him even more." The conversations seem to indicate a familiarity between Tokhtakhounov and Anissina. Tass, the official Russian news agency, reported that Anissina attended a ceremony in 1999 at a Paris hotel honoring Tokhtakhounov for his philanthropy. That Russian organized crime may have infiltrated international sport at the Olympics stunned Phyllis Howard, president of the U.S. Figure Skating Association. "This is a criminal act and it certainly puts things in a different league," Howard said. Lloyd Ward, chief executive officer of the U.S. Olympic Committee, said in a statement, "Competitors from all nations must be assured that they compete on a level playing field."

Question: "On what date did Anissina reveal that Gailhaguet had forbidden her from speaking with Tokhtakhounov?"

Answer: "On or about March 7th"

Input: Grande dame of cooking still going strong at 90: Julia Child celebrates in San Francisco. How does it feel to turn 90 and have attained the status of an icon, a living legend? "It feels just like it felt before," Julia Child says with the throaty laugh familiar to millions who cut their culinary teeth on her "French Chef" television series. The show, along with her seminal book, "Mastering the Art of French Cooking" (1961), revolutionized the way America cooks and eats. While making light of the difference a day -- or another decade -- makes, Child intends to enjoy her birthday thoroughly. First, there will be all the public observances, including a sold-out dinner Thursday at San Francisco's tony Fifth Floor restaurant, which -- like dinners that night at 19 other venues across the country -- will benefit the scholarship fund of the International Association of Culinary Professionals (which Child co-founded). Friday to Sunday, the action moves to Napa, with both members-only and public events at COPIA: The American Center for Wine, Food and the Arts, of which she is an honorary board member. Aug. 15, her actual birthday, will see her in Maine at an annual gathering of nieces, nephews, their offspring and friends, who for many years have rolled a joined birthday celebration for several members of the group into a jolly reunion. The schedule Child and her assistant of 14 years, former pastry chef Stephanie Hersh, have laid out is not exactly a senior-citizen routine, even though Child has always been candid about her age and realistic in assessing her own capabilities. When the Pasadena native moved back to California from her long-time home in the Boston area last year, she also made the move from a condominium she and her late husband, Paul, had purchased many years ago to a progressive retirement home. She is in the most active of the four levels available, but should the need arise, she can move on to assisted living facilities within the same complex.

Does the response "Art of French Cooking" correctly answer the question "As Julia Child turns 90, she will celebrate in San Francisco. The celebration will host many sold out dinners that will benefit which dear charity of Child's?"?
