Q: Read the article and select the best answer. Article: Nobody likes home economics . But restoring the program could help us in the fight against obesity and chronic diseases today. The home economics movement was founded on the belief that housework and food preparation were important subjects that should be studied scientifically. The first classes occurred in the agricultural and technical colleges that were built in the 1860s. When most departments of universities rejected women, home economics was a back door into higher education. Indeed, in the early 20th century, home economics was a serious subject When few people understood germ theory and almost no one had heard of vitamins, home economics classes offered vital information about washing hands regularly, eating fruits and vegetables and not feeding coffee to babies. However, today we remember only the fixed ideas about home economics, forgetting the movement's most important lessons on healthy eating and cooking. Too many Americans simply don't know how to cook. Our diets, consisting of highly processed foods made cheaply outside the home, have contributed to many serious health problems. In the last decade, many cities and states have tried to tax junk food heavily or to ban the use of food stamps to buy soda. Clearly, many people are doubtful about any governmental steps to promote healthy eating. But what if the government put the tools of obesity prevention in the hands of children themselves by teaching them how to cook? My first experience with home economics happened two decades ago when I was a seventh grader in a North Carolina public school. A year later, my father's job took our family to Wales, where I attended a large school for a few months. It was the first time I had ever really cooked anything. I remember that it was fun, and with an instructor standing by, it wasn't hard. Those lessons stuck with me when I first started cooking for my husband and myself after college and they still do. Teaching cooking in public schools can help solve some problems facing Americans today. The... Question: In the opinion of the author, how should we fight against childhood obesity? Options: A: Children should be taught how to cook. B: A heavy tax should be put on junk food C: Healthy eating should be promoted at school D: Using food stamps to buy soda should be banned
A: A

Q: Read the article and select the best answer. Article: What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology . With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory. In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs . The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones. It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future. Question: We can learn from the passage that _ . Options: A: human life will not last more than 120 years in the future B: human have to take medicine to build new skin cells now C: much needs to be done before humans can have a longer life D: we have already solved the technical problems in building new cells.
