Article: WASHINGTON--A baby born with the virus that causes AIDS appears to have been cured, scientists announced Sunday, describing the case of a child from Mississippi who's now 2.5 and has been off medication for about a year with no signs of infection. There's no evidence that shows that the child will remain healthy, although complex testing uncovered just traces of the virus' genetic material still lingering . If so, it would mark only the world' s second reported cure. Specialists say Sunday's announcement, at a major AIDS meeting in Atlanta, offers promising clues for efforts to remove HIV infection in children, especially in African countries where too many babies are born with the virus. "You could call this about as close to a cure," Dr. Anthony Fauci of the National Institutes of Health, who is familiar with the findings, told The Associated Press.     A doctor gave this baby faster and stronger treatment than usual, starting a three-drug mixture within 30 hours of birth. That was before tests confirmed the infant was infected and not just at risk from a mother whose HIV wasn't diagnosed until she was in labor . "I just felt like this baby was at higher-than-normal risk, and deserved our best shot," Dr. Hannah Gay, a pediatric HIV specialist at the University of Mississippi, said in an interview. That fast action apparently knocked out HIV in the baby's blood before it could form hideouts in the body. Those so-called reservoirs of dormant cells usually rapidly reinfect anyone who stops medication, said Dr. Deborah Persaud of Johns Hopkins Children's Center. Next, Persaud's team is planning a study to try to prove that, with more aggressive treatment of other high-risk babies. "Maybe we'll be able to block this reservoir seeding." Persaud said. No one should stop anti-AIDS drugs as a result of this case, Fauci warned. Question: We can infer that HIV is difficult to treat because   _  . Yes or no, is the answer "HIV is so clever that it hides when it feels danger"?

Article: We don't have beds in the space shuttle, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio.   On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float into a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. When I'm in space I don't need as much sleep as I do on Earth Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping. Question: How often does the sun rise to people in the space shuttle? Yes or no, is the answer "Every 90 minutes."?
(A).
No

Article: It was a Black Day for love in South Korea on Monday with lonely hearts trying to ease their pain by diving head first into bowls of noodles. South Korea celebrates Valentine ' s Day, where local custom dictates women give gifts to men.     It has taken on a popular event born in Japan but sweeping Asia known as White Day on March 14 when men return the favor with gifts for women. But Black Day, on April 14, is a South Korean original. It is marked by people who have not found love dressing in dark color1s and commiserating    over meals of black food, with the dish of choice being Chinese-style noodles topped with a thick sauce of black bean paste.   "I had a miserable time on Valentine ' s Day, felt even lonelier on White Day and now I' m crying over a bowl of' black noodles," said a young woman, "Things better be different next year.     At universities across the country on Monday, students without lunch dates ordered black noodles, dined with other lonely hearts and searched for companionship, South Korea marketers have used special days for the 14th of each month to create a calendar full of love. Some days have gained attraction such as Black Day, while others such as Green Day in August, when couples are supposed to drink cheap wine that comes in green bottles and walk in the woods, have yet to attract much of a following. Black Day events have snowballed, with a major matchmaking service this year providing an evening of speed dating where the dish of choice is sushi blackened by squid ink. An on-line company for movie tickets sponsored a speed eating competition of black noodles for those who bought single tickets for the latest films. "It is depressing enough going to the movies by yourself," said Shin Youn-joo of the company called Max Movie. "We just wanted to spread a little joy to the singles ." Question: The speed eating competition of black noodles is held to . Yes or no, is the answer "give some joy to the singles"?
