Example Input: Article: A new report says only about half of all students in the main school systems of America's largest cities finish high school. The report notes higher rates of graduation -- over 70% --in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation's fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people. Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true _ of the number of students who leave high school before finishing. Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America's Promise Alliance. The private group aims to help children receive services they need to succeed. General Colin Powell was chairman of America's Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future. Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school.

Example Input: Article: One day the employees of a large company in St Louis,Missouri returned from their lunch break and were greeted with a sign on the front door. The sign said:"Yesterday the person who has been hindering your growth in this company passed away. We invite you to join the funeral in the room that has been prepared in the gym." At first everyone was sad to hear that one of their colleagues had died,but after a while they started getting curious about who this person might be. The excitement grew as the employees arrived at the gym to pay their last respects. Everyone wondered:"Who is this person that was hindering my progress? Well,at least he's no longer here." One by one the employees got closer to the coffin and when they looked inside it they became speechless. They stood over the coffin,shocked and in silence,as if someone had touched the deepest part of their soul. There was a mirror inside the coffin:Everyone who looked inside it could see himself. There was also a sign next to the mirror that said. "There is only one person who can set limits to your growth:it is YOU." You are the only person who can revolutionize your life. You are the only person who can influence your happiness,your realization and your success. You are the only person who can help yourself. Your life does not change when your family changes,when your friends change,when your boss changes,and when your company changes. Your life changes when YOU change,when you go beyond your limiting beliefs,when you realize that you are the only one responsible for your life.

Example Input: Article: Have you wondered why you have two eyes and why they are set close together on the front of your face? The reasons are simple and important to the way you see the rest of your world. Your eyes are like two small cameras. A camera catches an image of an object and records it on film.Similarly,when you look at something,each eye takes in what it sees and sends this image to the back of the eyeball.Because your eyes are set close together,they view the world from about the same height but from slightly different angles. Working as a team, the eyes send the images to your brain, which puts them together into a single, centered image. Seeing in stereo means seeing with two eyes working together,which is called stereoscopic sight.This allows you to view the world in three dimensions,or 3-D.Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it.If images are coming from only one eye, however,only two of these dimensions-height and width-can be perceived.A world seen with one eye is thus two-dimensional,as in a photograph. Now consider why your two eyes are on the front of your face.Think of other animals with this same arrangement.They are all animals that hunt,like lions and wolves.Their eyes face directly in front of them.This provides a field of sight about 180 degrees wide,which is called binocular sight.On the other hand,animals that are hunted have eyes on the sides of the head,which provides nearly 360-degree field of sight.In order to stay alive,they need to see things coming from the sides and from behind.However,without stereoscopic sight,they have difficulty determining how far a danger is. With sight both stereoscopic and binocular,humans share with animal hunters the ability to see from side to side and to accurately determine the distance.If you think it would be great to have another type of sight,perhaps with hundreds of tiny eyes like many insects do,think again! Each tiny insect eye sees only a tiny part.Besides,what if you needed glasses? Be glad for the eyesight that you have.

A
