Q: Article: The oldest and hardest cow beef may be made as tender and tasty as young and choice met. "This declaration was made by the French physicist Denis Papin in book published in 1681, which described his "New Digester" or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121degC. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal --a replaceable rubber sealing ring. When Vischer's patent expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests.

Q: Article: A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too. A man's mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind. Memory is the diary that we all carry about with us.
Answer: hearing

A:
