[Q]: Article: After three military tours in Iraq and three in Afghanistan, Dennis Swols gets angry easily. He is unable to really talk about his time on the battlefield. But as Swols sits in a clinic at Fort Bragg, his hand drops to the furry head beside him. His mood brightens. Sitting at his feet, Lexy , a 5-year-old German shepherd, gives Swols a few moments of distraction . It's her job. And, according to Swols, she is good at it. "I have a hard time talking to people about my battlefield experiences and everything," says Swols, who took part in several wars. Now he's been suffering from post-traumatic stress disorder . "I just pet Lexy. Or I'm sitting here and we won't talk about military things. We'll just talk about the dog. My day is better every time I come in." For Doctor Christine Rumayor, Lexy is a partner and a living, breathing medical tool. The dog can calm a patient and make a therapy appointment a little more enjoyable. Animal therapy is used in only a few other army medical centers. A small number of dogs like Lexy are being used almost as co-therapists. The army is struggling to address stress disorders and mental health problems brought by more than ten years of war. One of the big difficulties is getting soldiers to seek treatment. Lexy, it turns out, is particularly good at that. Rumayor , who uses Lexy in her practice, said there was a resistance at first. "You don't expect everyone to think they can just bring their dog to work," she said. Walking around the base, she uses Lexy to attract soldiers, and then draws them into conversation. "There's nothing better than coming to an appointment where you get to have a warm furry thing that you get to pet all the time. People don't want to come in the door. When they see Lexy coming in, it makes them want to come in the door."
Answer: He is suffering from post-war stress.

[Q]: Article: No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting . For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. That many people feel their joints hurt is a sign of wet weather. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.
Answer: Weather forecasting is a way of telling what the weather will be like.
[A]: Which is true about weather forecasting?

[Q]: Article: A cute invention was revealed this month at the International Robot Exhibition (IREX) in Tokyo. It's called Jukusui-Kun ("deep sleep" in Japanese) ---a robotic pillow in the shape of a polar bear. The pillow is in fact a serious technological innovation hidden under a cute cover. It was developed by a group of scientists and engineers at Tokyo's Waseda University to help people suffering from snoring and those who live with them. This is how the robotic pillow works: a microphone detects the noise level of the snoring, and if the snoring becomes very loud, which can be the sign of sleep apnea , the bear will raise its hand and carefully touch the face of the sleeper, leading to a change in the sleeper's position without waking him or her up. This is definitely the world's first anti-snoring machine and an important potential treatment for sleep apnea. This sleeping disorder involves pauses in breathing, and can lead to heart attacks during sleep. In Japan, around 2 million people are struggling with the problem. When a sleeper starts snoring, the sleeper's blood oxygen level drops. The new device tracks the level of oxygen in the sleeper's blood and wirelessly sends the information to the polar bear. But the only problem is that people not only have to sleep on a bear-shaped pillow with robotic hands, but also have to insert their hands into a monitor that keeps track of blood oxygen levels. If these levels fall below a certain point, it gives the bear another cue to lift its hand. The bear is not yet on sale, and it remains to be seen whether a robotic hand reaching up to touch one's face is any more effective than one's partner giving one a good shove .
Answer: With this device, the sleeper's hands can't move freely while sleeping.
