Article: Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health.

Article: In Vietnam, two members of a family of street vendors are finding a way to help the poorest students in Hanoi. Pham Minh Dap and his brother are providing the students with mostly free English and Japanese lessons at a learning center they created. The men want to help people who would not normally have a chance to learn a foreign language. Some education experts in Vietnam say such knowledge may help college graduates get jobs. The country's economy has improved. But many graduates continue to have a hard time finding employment. Local media reported ten percent of university graduates do not have a job. Earlier this year, 24-year-old Pham Minh Dap and his brother established a school they call "Stand By You". Volunteers teach poor students English and Japanese. Many classes are free. Students with some language knowledge pay 25 to 50 cents per class. Mr. Dap pays about $ 500 to rent the language center space and for other costs. He gives about $ 150 from his earnings as a street Vendor and private language teaching. His brother gives the same amount from the money he earns as a secretary. Friends provide the rest. Mr. Dap and many of his family members have sold things outside HoaBinh Park in the center of Vietnam's capital for five years. They come from a village of rice farmers in Thanh Hoa Province. Twenty-four-year-old Pham THi Trang is one of 600 students at the language school. She is finishing her university studies. Her parents work in a market in a village in Ha Nam Province. She says life is hard in the city. She earns about $50 a month from a part-time job, and her parents give her $ 75. But this is not enough to live on. She has said she has to be very careful with money so she can pay her bills. Demand for the school is growing. About 1,000 people are on a waiting list to enter. Ten people have offered to teach for free. And Mr. Dap says he is hoping to raise money to pay for a bigger place. He wants to open more classes.
Answer: by two brothers

Article: Some British and American people like to invite friends for a meal at home. But you should not be upset if your English friends don't invite you home. It doesn't mean they don't like you! Dinner parties usually start between 7 and 8 p.m., and end at about 11. Ask your hosts what time you should arrive. It's polite to bring flowers, chocolates or a bottle of wine as a gift. Usually the evening starts with drinks and snacks . Do you want to be more polite? Say how much you like the room, or the picture on the wall. But remember--it is not polite to ask how much things cost. In many families, the husband sits at one end of the table and the wife sits at the other end. They eat with their guests. You'll probably start the meal with soup or something small, then you'll have meat or fish with vegetables, and then dessert, followed by coffee. It's polite to finish everything on your plate and to take more if you want it. Did you enjoy the evening? Call your hosts the next day, or write them a short thank you letter. British and American people like to say " Thank you, thank you, thank you." all the time!
Answer: you'd better bring a certain present with you

Ex Output:
If you are going to attend a dinner party, _ .
