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. Mauna Loa was chosen as the experimental site because   _  . A) it is located near a rocket base B) other people can hardly find the location C) its landscape is so much like that of Mars D) it is a safe place to conduct the experiment

Moving to a new city and state was difficult for me, especially in winter. Little did I know that a Colorado snowstorm would greet me after I had been in my new home for only a week. I just missed home. But more than the old house and the beach, I missed Stacey, my best friend. And I missed our lovely tea. Going to a sweet little tearoom, we had discovered was a special treat for us. The place was a Victorian dream, with delicate teacups and tablecloths with flower prints. The hat shelf near the front door swept us back to childhood. Stacey and I became little girls, trying on different hats until we found the perfect one for our dress-up tea party. We would then choose a lovely table and order our tea. That was a precious time, filled with laughter between scones  and sharing our lives between tiny cucumber sandwiches. Springtime descended upon Denver, and the sun lightened my heart. But I still fought loneliness almost every day. I decided to explore the Denver area. While my husband went to the office, I took time to see what our new area had to offer. One day, I was walking along the street when suddenly the words "Tea Leaves" caught my eye. A tea room? Here, in the land of loneliness and pain? I walked through the doors, and tears came to my eyes. It was a beautiful room, not Victorian, but simple and lovely. I sat down and ordered a pot of tea, a cucumber sandwich, and some scones.It felt silly and wonderful --- and it felt like home. For the first time since moving, I felt as if this new city and state could be, would eventually be, my home. I would come back here and bring new friends. When Stacey visited, we would come here. I lifted my cup and made a silent toast. I toasted Stacey, whom I missed  ly, and I toasted the sweet little tearoom that lessened my pain. We can infer from the text that the author would probably   _  . A) open her own teahouse B) ask the owner of the teahouse to decorate it like a home C) make new friends in Denver D) go back to her hometown to visit Stacey

Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to an outlet that is acceptable in the domestic   setting. One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn't solve all behavior problems, but it is the foundation for solving just about any problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of "come here, sit," it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack   by using extreme measure. You can teach your dog its subordinate   role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge. Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal. Behavior problems of dogs are believed to   _  . A) occur when they go wild B) be just part of their nature C) get worse in modern society D) become a threat to the community
(A).
