Article: Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago. The scientists say that the human body has changed very little since human first appeared on the earth,but the way we live has changed greatly. Our body has not been able to deal with these changes in lifestyles and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called "diseases of civilization ".Many cancers and diseases of the blood system,including heart attacks and strokes are examples of such diseases. Scientists noted that early stoneage people used very little alcohol or tobacco ,probably none. Ancient people also got a great deal of physical exercise,but a change in food is one of the main differences between life in ancient times and life today. Stoneage people hunted wild animals for their meat ,which had much less fat than farm animals. They also ate a lot of fresh wild vegetables and fruits. They did not use milk and other dairy products ,and they made very little use of grains . But today,we eat a large amount of dairy products and grain foods. We eat six times more salt than stoneage people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live as people thousands of years ago did,but scientists say that we would be much healthier if we ate as those ancient people did,cutting the amount of fatty,salty and sweet foods. Question: What is the main cause mentioned in the article why people today suffer from a lot of new sicknesses? Yes or no, is the answer "Food is quite different between life today and life in ancient times."?
Yes

Article: Pulling heavy suitcases all day in the summer is hard work, especially when you're a thin 14-year-old.That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsyl-vania Railway Station. After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it." When I got home that night, I told my dad what I wanted to do." You give an honest day's work," he said, looking at me straight in the eye." They're paying you. If they want to do that, you let them do that." I followed my dad's advice for the rest of that summer and have lived by his words ever since. Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possessions. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone. Whether you're on a sports team, in an office or a member of a family, if you can't trust one another, there's going to be trouble. Question: It can be concluded from the text that _ . Yes or no, is the answer "his experience as a baggage boy had a great influence on his later life"?
Yes

Q: Article: Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world. I was pretty shocked when I first stepped onto the campus. Well, it's not even really a campus. It's more like a district in a small town. Harvard's main buildings are from the 18thcentury. They look very old and simple. You might even say they're a little shabby. They don't fit the modern idea of university at all. The buildings are surrounded by grass and trees, so I felt as if I had walked into a medieval castle. But when I looked across the street, busy shops and in-fashion students made me feel like I was in the 21stcentury again. It creates a strong contrast and brings a special atmosphere to the school. Our tour guide Gary took us around and told us, "You see this grass field in the center of the school? Here is where they host their graduation ceremony. They just set up tents and benches and have a very simple ceremony. Unbelievable! Who would think the most talented students just graduate on the lawn?" I saw some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of pages turning, along with the chirping of the birds, I felt very calm. There was no competitive feeling at all. Harvard has the world's first computer in its science center and there are hundreds of high-end computers too. Its religion and the literature departments are also among the best. It is the perfect mix of tradition and new technology. It makes Harvard a very attractive place to study in. I hope one day I'll attend my dream school---Harvard. Question: According to the article, in which fields is Harvard top in the world Yes or no, is the answer "Religion, computer science and literature"?
A: No
