question:
You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air. <sep>What happens when less heat reaches the surface of your skin?<sep>Cools the body
answer:
No


question:
Jake was walking to the park to play baseball with his friends. He loved being outside on sunny days, and now that school was over for the year, he was playing baseball every day. The more he played, the better he got. Only Frank was better than he was. He liked playing third base, but he often played in the field. He was carrying his favorite mitt that his Grandfather had bought him. His Grandfather had taught him to catch. He loved spending time with him when he was younger, but he had moved last year. Now he only saw his Grandfather in the summer. Jake was really excited to show him his skills when he came to their next game. He could throw really fast now. He was sure his Grandfather would want to sit in the front to watch him. He knew he would jump up and down. Jake happily ran the rest of the way to the park thinking about how much fun he was going to have playing baseball this year. <sep>Did jake walk to the park everyday to play baseball with his friends during school days?<sep>No
answer:
No


question:
Allan sat down at his desk and pulled the chair in close. Opening a side drawer, he took out a piece of paper and his inkpot. After filling his pen, Allan looked at his paper in the orange glow from the lantern set back in the desk's right-hand corner. His pen cast a forbidding line of shadow slanting across the page, echoing the inky darkness crouching in the edges of the lantern's struggling glow. The only other illumination came from a lurid moonlight filtered through thin branches and clouds, casting its bone-pale glow onto the pine floorboards. Allan unfolded another page, this one crowded with ranks of letters in tight formation from left to right. The lines of letters stepped into their divisions, in the shape of a story's outline: the loose, dry skeleton of a tale lay exposed beneath their feet, awaiting tendons, muscle and blushing skin. Allan reviewed the troops, all prepared to disembark, their task to form the tale of a young man returning home from Life Abroad to find his childhood friend a bride to-be, thus upsetting the apple cart of his life's plan, clarified – of course – by his very time away from her he loved best. Although the concept was a simple one, Allan thought it had potential. Besides, the public liked a good, simple romance. Perhaps this will be more saleable, he thought and began to write. They gazed at each other, lost in the rapture of love based so deeply within their hearts that they had never seen it before. "What about Roger?" she asked, knowing that the answer no longer mattered. <sep>What are the two light sources Allan is using to write?<sep>Secret service
answer:

No
