Input: Consider Input: Article: Mrs. Janes gave music lessons at a school.She had a good voice and enjoyed singing, except that some of her high tones sound like a gate that had forgotten to oil.Mrs. Janes knew her weakness well, and took every chance she could find to practise these high notes. As she lived in a small house, where she could not practise without disturbing the rest of the family, she usually went for long walks along the country roads whenever she had time and practised her high notes there.Whenever she heard a car or a person coming along the road, she stopped and waited until she could no longer be heard before she started practicing again, because she was a shy person. One afternoon, a fast, opened car came up behind her so silently and so fast that she didn't hear it until it was only a few yards from her.She was singing some of her highest and most difficult tones at that time and as the car passed, she saw an anxious expression came over the driver's face.He stopped his car suddenly, jumped out and began to examine all his tyres carefully. Mrs. Janes didn't dare to tell him what the noise he had heard really was, so he got back into the car and drove off.
Answer: She sang terribly, she was no singer at all.

Output: How did Mrs. Janes sing?

Input: Consider Input: 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.

Output: What do we know about Dennis Swols ?

Input: Consider Input: Article: Just five minutes of exercise a day outdoors can improve mental health, according to a study. Researchers from the University of Essex, UK have found that as little as five minutes of a "green activity" such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem . Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show. Barton and Pretty looked at data from 1,252 people of different ages, genders and mental health status taken from 10 studies in Britain. They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail . They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent. Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill. Green and blue A bigger effect was seen with exercise in an area that also contained water - such as a lake or river. "This is because historically we are drawn to water to survive and it is in our genetic make-up to be at one with nature," the researchers wrote in their report. Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from "green exercise". "Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health." He also said exercise programs outdoors could benefit youth offenders.
Answer: It determined the exact amount of time needed.
Output: How is the study this article refers to different from other studies?
