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: Seven years ago I was 13 years old. I still remember to this day where I was and how it all came down. I was in my social studies classroom, when a teacher came back and told us that the first building of the World Trade Center was hit by a plane. We immediately stopped our work and turned on the television. Throughout half the day we watched TV until the school was forced to let all of us home early. I walked home and immediately turned on the television and watched until my bedtime. I remember always seeing the towers walking to my Tae Kwon Do school; to me, a boy teenager, it was a great thing because at that time I have never seen any other building that caught my eye as much as _ did. And walking to my school that day was just a horrifying dream. Crossing the busy road of the Bell Pike was a big cloud of smoke and dust. It was very upsetting. Every day after that horrific day I looked up to the once stood Twin Towers just to see nothing there. To my eyes, that day will always be in my mind and in my heart, even though I didn't lose any loved ones, I still feel the pain as if I did. September 11th, 2001 will never be forgotten.
Answer: He was in the classroom.

Output: Where was the writer when the tragedy took place?

Input: Consider Input: Article: Family traditions were important in our house, and one was more appreciated than our annual trip to the woods for the perfect Christmas tree. "Dad, can we watch when you trim it?" my eldest son ,John ,asked on the way home. "I won't be cutting this year," my husband said." You and your brother Dan are old enough to measure things, fit the tree to the stand and do it by yourselves. Think you boys can handle it?" They seemed to _ in their chairs at the thought of such an amazing responsibility. "We can handle it," Dan promised. We won't let you down." A few days before Christmas, Dan and John rushed in after school. They gathered the tools they'd need and brought them out of yard, where the tree waited. I left the older boys to their work and brought David inside for his early supper. A moment later I heard the happy sounds as the boys carried the trees into the living room. Then I heard the sound become dead silence. I hurried out to them. The tree was too short. John crossed his arm tight across his chest. His eyes were filled with angry tears. The tree was central to our holiday, but it was not what I worried about. I didn't want the boys to feel ashamed every time they looked at it. We had a terrible problem on our hands. I couldn't lower the ceiling, and I couldn't raise the floor either. There was no way to repair the damage. If I couldn't fix the problem, maybe I could get creative with it. A thought came to my mind, which turned to the solution. I followed them back into the living room.. "We can't make the tree taller," I said. "But we can put it on a higher position." Dan turned his head sideways, measuring the distance with his eyes . "We can put it on the coffee table and put the lights and decorations on before we lift it up . Thus, we won't need a ladder. It just might work! Let's try it!" When my husband got home and looked at the big tree on top of the coffee table, Dan and John held their breath. "What a good idea!" he declared, as if the boys had gone beyond all his expectations. "Why didn't I ever think of such a thing ?" John broke into a grin. Dan's chest swelled with pride. David squealed.
Answer: The writer's husband
