Read the following article and select the best answer. Article: The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word "activity". As long as you're getting your body moving, it doesn't have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics , strength building, and flexibility exercise. Make exercise a habit by arranging some time every day. On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it's OK to divide it into shorter exercise breaks throughout the day. Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school -- or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you've probably reached your 60 minutes. Here are five simple ways to make an exercise lifestyle change: Question: The author advises dividing activity into shorter exercise breaks because _ . - exercising for a long time is bad for people's health - it has the same effect as soccer practice - people usually haven't much time to exercise - no one can spare lots of time to exercise
people usually haven't much time to exercise

Q: Read the following article and select the best answer. Article: The size and shape of your ears show your character more than any other parts of the face. Other parts of the face change shape as we get older, but ears do not change their shape. They only change in size. Reading people's character from their ears is an old science. In very old times people thought that a person with big ears had a good and generous character. They thought that a person with pale, small ears was dangerous. They also thought that the shape of the ear showed if a person was musical. Today, too many people believe that the size and the shape of the ear help you know if a person is musical. Ears are all different, and each characteristic has a meaning. Next time when you look at a person, see if his ears are large, medium-size or small. Look at the lobes (the lowest part of the ear). Do they stick to the face? Ears that are always red mean a person may easily get angry, or he / she just has high blood pressure . Ears that are always cold and pale mean a person has a nervous character. And a big inside hole of the ear means a person is musical. Question: When a baby is born, _ . - his / her ears are red - his / her ears will not change all the life - he / she will get large ears - his / her ears will not change in shape
A: his / her ears will not change in shape

Read the following article and select the best answer. Article: Health officials in Canada are very busy these days. They are placing chickens at fixed points all along their 2,500 km border with the United States of America. It's not a joke, nor have the Canadians gone mad. They are using these chickens to see if the West Nile virus is still around. The virus infects birds, so the chickens have a chance of catching the virus and fall ill. The West Nile virus is spread among humans. It killed seven people in New York last year. Countries around the world are realizing that it may just be possible to stop certain kinds of people from entering their land. However, it is very difficult to stop viruses traveling from one end of the earth to another. When they travel to new places, they get used to the environment very easily and sometimes start destroying the local plant and animal life. These biological polluters are called smart polluters. These smart polluters can be carried across borders of countries unknowingly. Just as we humans are travelling across the world more often than earlier, these biological polluters have also started journey much more. They slide into airplanes through their wheels. They dig into objects that travelers may be carrying from one country to another. There are some good examples of how these polluters work. The water hyacinth of South America is blocking lakes in China and Africa. Tree snakes from Papua New Guinea are busy eating up some birds in the country of Guam, which breaks its natural balance. That's why the customs officials in many foreign countries prevent people from bringing in a small plant, or an object made of wood that is in its natural form. The customs officials have these rules because these varieties of plants are special to certain places. The plants have the power to spread new illnesses among native plants and animals. Biological polluters always create problems in places where they do not belong. They could be special varieties of plants, bugs or even animals. Question: Customs officials in many countries prevent people from bringing in _ . - chocolates - shoes - pictures - plants
plants
