Read the following article and select the best answer. Article: I chose to study in Madrid because I had a desire to learn Spanish. My first impressions of Madrid were incredible. It was before the New Year that I arrived in Madrid for the first time. While traveling to my Spanish friend's house in a taxi, I appreciated the buildings along the road which were different from those of my own country. There are an incredible number of restaurants and bars from all over the world. If you are really into sightseeing, I hope you have rechargeable batteries for your digital camera, because one week really isn't enough time to see everything here including a number of art, science, and historical museums as well as parks, buildings, and amazing landscapes. What I liked best about life in Madrid was the fact that if you were frustrated with schoolwork and wanted to have some fun, you can easily go out. The nightlife never seems to stop and the people are all very friendly. You can meet people and practice Spanish while having fun at the same time. What I liked least was the fact that many people smoked in the streets. Also, coming from the US, I was used to having a big breakfast every morning, but while living with an actual Spanish family, I wasn't really satisfied with the food in the morning. I think I have definitely become more independent since I came back from Spain. Living in a big city like Madrid ,I found that it is necessary to plan ahead and to make a schedule for future. There is so much to see, not just in the Spanish World, but in the European World as well. Question: What's the purpose of the text? - To attract people to tour around Madrid. - To show how to enjoy Spanish culture. - To give advice on how to study Spanish. - To describe the author's life in Madrid.

Q: Read the following article and select the best answer. Article: Your chair is your enemy. That is the conclusion of several recent studies. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don't. So what's wrong with sitting? The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy. You may think you have no choice about how much you sit. But this isn't true. Suppose you sleep for eight hours each day, and exercise for one. That still leaves 15 hours of activities. Even if you exercise, most of the energy you burn will be burnt during these 15 hours, so weight gain is often the cumulative effect of a series of small decisions: Do you take the stairs or the elevator? Do you walk to the corner store, or drive? But it looks as though there's a more sinister aspect to sitting. Some evidence suggests that when you spend long periods sitting, your body actually does things that are bad for you. Lipoprotein lipase is a molecule that plays a central role in how the body processes fats. Low levels of lipoprotein lipase are associated with a variety of health problems. Studies in rats show that leg muscles only produce this molecule when they are actively being moved. The result is that when you sit, an important part of your metabolism slows down. You may also have a higher risk of suffering from diabetes . Some people have advanced radical solutions to the sitting syndrome : replace your sit-down desk with a stand-up desk, or watch television in a rocking chair. But whatever you choose, know this. The data is clear; look out for your chair. Question: The author mentions lipoprotein lipase mainly to _ . - show that it plays a big part in keeping us healthy - tell us that it isn't produced while we are sitting - suggest that we should take less exercise to be healthy - prove sitting for long is bad for our body
A: prove sitting for long is bad for our body
