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 "East or west" correctly answer the question "Which directions could you be going if you followed the equator?"?

OPTIONS:
- no
- yes

The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Question: "What happens in the large intestine?"

OPTIONS:
- no
- yes

Answer: "Nutrients are absorbed"

Response: no

Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water.

Question: "What are the physical properties of matter, and how many primary states are there for matter?"

Response: "solid and gas"
OPTIONS:
- no
- yes

A: no

Problem: Neighborhood Legal Services, which provides free legal services to the poor, has expanded into the San Gabriel and Pomona valleys, areas with large Asian populations, many of whom speak limited or no English. Language is their biggest obstacle, but the Asian communities' cultural isolation and service providers' lack of cultural expertise also play a part, said NLS executive director Neal Dubovitz. And with 13 percent to 15 percent of the Asian population in the U.S. living below the poverty line, NLS services are badly needed, Dubovitz said. "Although it is a significant part of the poverty population, Asians historically have not been able to participate in the services and programs available to the poor," he said. From simple telephone advice to complete legal representation in court, the agency provides free consumer, health, family, immigration, housing, public benefits and labor legal services to people who earn under $1,380 per month. Legal service providers have long served large Latino populations, who have cultural diversity but share a common language. "I remember the days when there were only a handful of people in the legal offices who spoke Spanish," Dudovitz said. "Now Spanish and English are interchangeable. Our goal is to have that for the major Asian languages as well." Before the expansion, only a few NLS lawyers spoke Asian languages, said attorney Rebecca Yee, who was hired by NLS in April 2002 to design and head the project. "Now we have people speaking Cantonese, Mandarin, Thai, Khmer (from Cambodia), Korean, Vietnamese, Japanese and Tagalog," Yee said. One of the 13 attorneys hired to work with the program is Irene Mak, a family law attorney who speaks Cantonese, Mandarin and Thai. Mak was a partner at a private law firm before she went to work for NLS two years ago, earning up to $20,000 less a year working on domestic violence cases. "The job is more satisfying than the money," said Mak, who grew up in Hong Kong and Thailand before coming to the United States. "I could use my language skills and wanted to give back to the Asian community." NLS expanded when Legal Services Corp., the federal agency that funds providers of free legal services nationwide, reduced the number of grantees in the Los Angeles area from five to three, Dudovitz said. NLS won the competitive grant over the Legal Services Program for Pasadena, San Gabriel-Pomona valleys. That boosted its client base from 16,000 to around 25,000, and NLS opened an office in El Monte.

Question: "How do the attorneys working with the program feel about it?"

Answer: "They feel satisfied"

OPTIONS:
- no
- yes
Answer: yes

Military Notification and Response. Boston Center did not follow the protocol in seeking military assistance through the prescribed chain of command. In addition to notifications within the FAA, Boston Center took the initiative, at 8:34, to contact the military through the FAA's Cape Cod facility. The center also tried to contact a former alert site in Atlantic City, unaware it had been phased out. At 8:37:52, Boston Center reached NEADS. This was the first notification received by the military-at any level-that American 11 had been hijacked: FAA: Hi. Boston Center TMU [Traffic Management Unit], we have a problem here. We have a hijacked aircraft headed towards New York, and we need you guys to, we need someone to scramble some F-16s or something up there, help us out. NEADS: Is this real-world or exercise? FAA: No, this is not an exercise, not a test. NEADS ordered to battle stations the two F-15 alert aircraft at Otis Air Force Base in Falmouth, Massachusetts, 153 miles away from New York City. The air defense of America began with this call. At NEADS, the report of the hijacking was relayed immediately to Battle Commander Colonel Robert Marr. After ordering the Otis fighters to battle stations, Colonel Marr phoned Major General Larry Arnold, commanding general of the First Air Force and NORAD's Continental Region. Marr sought authorization to scramble the Otis fighters. General Arnold later recalled instructing Marr to "go ahead and scramble them, and we'll get authorities later." General Arnold then called NORAD headquarters to report. F-15 fighters were scrambled at 8:46 from Otis Air Force Base.

Question: "Which jet did the military scramble?"

Response: "F-15s"
OPTIONS:
- no
- yes
