Question: Article: After an extra day in space,the crew of Discovery returned to Earth,landing at Edwards Air Force Base in California early on Tuesday morning.The shuttle and its crew spent two weeks in space,most of it aboard the International Space Station.It was the first flight of NASA's spaceshuttle fleet since February 2003,when the shuttle Columbia came apart while reentering Earth's atmosphere. NASA officials delayed Discovery's return for one day because of cloudy weather in Florida,where the shuttle was supposed to lanD. On Tuesday morning,mission controllers directed Discovery to a landing site in California,where the skies were clear.The crew members will have to wait until Wednesday to see their families when they all meet together in Houston at the Johnson Space Center. Discovery had a very busy mission in space,compared to past missions.The space shuttle docked with the International Space Station most of the journey,delivering badly needed supplies and repairing damaged parts.The crew spent a lot of time testing new repair techniques on their own shuttle,conducting three different spacewalks(where astronauts exit the space shuttle to do work outside).On the third spacewalk,astronaut Steve Robinson went underneath the shuttle to remove material sticking out from between the spacecraft's protective tiles. There were concerns in the last remaining days of Discovery's mission that a torn heat blanket--another shield against overheating in the space shuttle--may pose a problem to crew members. NASA officials and technicians worked on ways that the crew could fix the problem, but later decided it was not a risk. With the shuttle and its crew safely back on firm ground, NASA is hailing this mission, labeled STS114,as a huge success. "I hope this shows people that we're coming back," NASA spaceflight chief Bill Readdy said after Discovery's successful landing. "We've got some more work to do. We know what we need to do and we'll do it.
Answer: Finding the cause why the shuttle Columbia came apart.

Answer: Which of the following isn't included in the jobs of the shuttle Discovery?

Question: Article: Every immigrant leads a double life. Every immigrant has a double identity and a double vision, being suspended between an old and a new home, an old and new self. The very notion of a new home, of course, is in a sense as impossible as the notion of new parents. Parents are who they are; home is what it is. Yet home, like parentage, must be legitimized through love; otherwise, it is only a fact of geography or biology. Most immigrants to America found their love of their old homes betrayed: they did not really abandon their countries; their countries abandoned them. In America, they found the possibility of a new love, the chance to nurture new selves. Not uniformly, not without exceptions. Every generation has its Know-Nothing movement. Its understandable fear and hatred of alien invasion is as true today as it always was, but in spite of all this, the American attitude remains unique. Throughout history, exile has been a disaster; America turned it into a triumph and placed its immigrants in the center of a national epic. The epic is possible because America is an idea as much as it is a country. America has nothing to do with loyalty to a dynasty and very little to do with loyalty to particular place, but everything to do with loyalty to a set of principles. To immigrants, those principles are especially real because so often they were absent or violated in their native lands. It was no accident in the '60 and '70s, when alienation was in flower, that it often seemed to be "native" Americans who felt alienated, while aliens or the children of aliens upheld the native values. The immigrant's double vision results in a special, somewhat skewed perspective on America that can mislead but that can also find revelation in the things that to native Americans are obvious. Psychiatrist Robert Coles speaks of those "who straddle worlds and make of that very experience a new world." "Home is where you are happy." Sentimental, perhaps, and certainly not conventionally patriotic, but is appropriate for a country that wrote the pursuit of happiness into its founding document. That continues for the immigrant in America, and it never stops, but it comes to rest at a certain moment. The moment is hard to pin down, but it occurs perhaps when the immigrant's double life and double vision joint together toward a single state of mind. When the old life, the old home fade into a certain unreality: places one merely visits, in fact or in the mind, practicing the tourism of memory. It occurs when the immigrant learns his ultimate lesson: above all countries, America, if loved, returns love.
Answer: Immigrants have played an important role in America's history.

Answer: What's the result of American's unique attitude toward immigrants?

Question: Article: October 15th is Global Handwashing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap. Experts say people around the world wash their hands but very few use soap at so-called extremely moments. These include after using the toilet,after cleaning a baby and before touching food. Global Handwashing Day is the idea of the Public Private Partnership for handwashing with soap. The goal,they say,is to create a culture of handwashing with soap. The organizers say all soaps are equally effective at removing disease-causing germs .They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas,including under the fingernails. Then,wash well under running water. Finally,dry your hands with a clean cloth. The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell,which increases the chances that people will wash again. It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea ,which is the second leading cause of child deaths,killing more than one and a half million children a year,by almost half.
Answer: It gets all people into the habit of washing hands.

Answer:
Which fact can't explain why soap is important?
