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?

Article: To many Americans,Labor Day marks the end of the summer,a day off from work and school,and one last chance to relax.But Labor Day is much more than just a day off . It represents a very important victory for laborers everywhere.The holiday is a celebration of the social and economic achievements of American workers. More than a century ago workers were forced to deal with harsh conditions.They were paid very little and they often worked 10-to l2-hour days.Men, women and even small children were forced to work even when they were sick.Tired of long hours and dangerous conditions,workers began organizing themselves into labor unions.On top of fighting for higher pay and shorter workdays,they also fought for the rights of children.The workers wanted employers to place limits on the age of their workers so that small children were not overworked or hurt in factories. A New York City carpenter named Peter McGuire is credited for coming up with the idea for Labor Day.In 1872,after working many hours under poor conditions, McGuire _ 100,000 workers to go on strike.The workers marched through the streets of New York City,demanding a better work environment.McGuire spent a decade fighting for workers' rights.In 1882,he proposed the idea to create a special holiday for workers.On Tuesday,September 5,1882, more than 10,000 workers hit the streets of New York City for the first ever Labor Day parade.Two years later the celebration was moved to the first Monday in September.And in 1894,Congress passed a law making Labor Day a national holiday.Americans celebrated the first Labor Day holiday with a parade,picnics and fireworks. Today,many people hit the road to enjoy the last of their summer vacation.Others enjoy the long weekend with picnics,backyard barbecues or just rest and relaxation.However you spend Labor Day,remember that the holiday is a time to pay tribute to the workers who have made America what it is today.
Answer: The first ever Labor Day parade was held in 1882.

Article: (NEW YORK)---Scientists have discovered small signs of awareness in some vegetative brain injury patients and have even communicated with one of them---findings that are beneficial to how to assess and care for such people. The new research suggests that standard tests may ignore patients who have some consciousness, and that someday some kind of communication may be possible. In the strongest example, a 29-year-old patient was able to answer yes-or-no questions by picturing specific scenes the doctors asked him to imagine. "We were stunned when this happened," said one study author, Martin Monti of the Brain Sciences Unit in Cambridge. "I find it really amazing. This was a patient who was believed to be vegetative for five years." Ever since a research paper four years ago described obvious signs of awareness in a vegetative patient, families of patients have been demanding brain scans, said Dr. James Bernat, a spokesman for the American Academy for Neurology. But experts said more study is needed before the specialized brain scans could be used in medical treatment. "It's still a research tool," Bernat said. Experts also pointed out that only a few tested patients showed evidence of awareness. And they said it is not clear what degree of consciousness and mental abilities the signs imply. They also noted that the positive signals appeared only in people with traumatic brain injury---not in patients whose brains had been lacking in oxygen, as can happen when the heart stops. The new study used brain scanning called functional MRI, for 23 patients in a vegetative state and 31 that are minimally conscious. Patients are said to be in a vegetative state if they are tested and found unable to do such things as move on command or follow a moving object with their eyes. Minimally conscious patients show signs of awareness, but they are minimal and discontinuous.
Answer: It drives the government to care about vegetative patients.
answer:
