Question: Article: Six volunteers are about to find out what it would be like to live on Mars without ever leaving the Earth. Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii. They are part of an experiment that is designed to mimic life on Mars. Their mission began on October 15, 2014. NASA says it could send astronauts to Mars as early as the 2030s. The mission would take more than two years, so NASA needs to know how people would react to living in a small group, isolated from the rest of the world, for such a long time. Some people may become depressed or bored living under those conditions. By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission, and how to help them get along. They will live in a two-story building. The ground floor is about 86 square meters, roughly the size of a small two-bedroom apartment. It includes shared areas like kitchen, dining room, bathroom, laboratory and an exercise room. The upstairs is less than half the size of the downstairs. It contains another bathroom and six small bedrooms. The building is located in an abandoned quarry about 2,400 meters up the side of Mauna Loa, the second biggest volcano in the world. It is constantly monitored for signs of volcanic activity. NASA chose the location because the appearance looks very similar to Mars. To make it more like being on Mars in the future, they are only able to communicate by email during the experiment. Meanwhile, there will be a 20-minute delay between the time when a message is sent and that when it is received. When they go outside, they will have to suit up in full spacesuits, just as if they were on Mars. The commander is Martha Lenio, a 34-year-old Canadian. During the mission, she will run experiments on growing food. The other members have backgrounds in physics and so on. None of them are astronauts.
Answer: On June 15, 2015.

Answer: When will the six volunteers end their mission about mimicking life on Mars?

Question: Article: Among all the fast growing science and technology, the research of human genes , or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people. The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by _ s. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied , not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span can be prolonged. Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it and a healthy child will be born. Some people are worrying that the gene research can be used to manufacture (produce) human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
Answer: Expressing the writer's idea that gene technology will benefit people

Question: Article: Nick Vujicic was born with no arms or legs, but the brave 32-year-old man, plays football and golf, swims, and surfs. Nick has a small foot on his left side, which helps him balance and enables him to kick. He uses his one foot to type, write with a pen and pick things up between his toes. "I call it my chicken drumstick ," joked Nick, "I'd be lost without it. When I get in the water I float because 80 per cent of my body is lungs and my drumstick acts as a propeller." When Nick was born his father was so shocked he left the hospital room to vomit. His _ mother couldn't bring herself to hold him until he was four months old. "It was so hard for them, but right from the start they did their best to make me independent. My dad put me in the water at 18 months and gave me the courage to learn how to swim. " said Nick. Throughout his childhood Nick dealt with the typical challenges. At the age of seven, Nick tried out some specially designed electronic arms and legs, in hope that he would be more like the other kids. During the short trial period of the electronic arms and legs, Nick realized that even with them, he was still unlike his peers at school, and they turned out to be much too heavy for Nick to operate, affecting his flexibility quite significantly. "When I was 13 I read a newspaper article about a disabled man who had managed to achieve great things and help others," said Nick, "I realized why God had made us like this - to give hope to others. It was so inspirational to me that I decided to use my life to encourage others and decided to be thankful for what I do have, not get angry about what I don't." "I tell people to keep on getting up when they fall and to always love themselves," he said. "If I can encourage just one person then my job in this life is done." By now, he has visited 35 different countries, touring the world as a motivational speaker.
Answer: His small foot.

Answer:
What makes it possible for Nick to swim in the water?
