I'm taking a test and have to guess the right answer to the question after the article. Article: Half of the world's population is affected by Asian monsoons , but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions. Every year, damp air masses,known as monsoon,produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south. According to Edward Cook , a weather expert at Columbia University in New York., the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places. Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s. Professor Cook says the tree-ring records show periods of wet and dry weather. "If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability." With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons. "There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive...

I'm taking a test and have to guess the right answer to the question after the article. Article: It seems school children all over the world complain about their school food. Cherie Blair, the wife of previous Prime Minister Tony Blair, said that she would prepare a packed lunch for her son if school dinners do not improve. So what do students of your age eat for lunch at school? Japan High schools have canteens , which serve everything from noodles to rice, but not burgers and chips. Other children bring food from home such as cold rice balls, meat or fish, pickles and vegetables. Students take home a menu for the coming month containing notes on nutrition value. Twice a year parents are invited to have a taste of the food. The class with the fewest leftovers at the end of the month receives a prize. Untied States A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies. School lunches must also provide at least one-third of the daily dietary allowances of protein, vitamin A, vitamin C, iron, calcium, and calories. Australia Meat pies, sausage rolls and hotdogs are all traditional dishes in Australian school shops. But as the nation pays more attention to children's health, healthier foods have started to find their way onto school menus. Many schools have used a traffic light system. The sale of red-labelled foods, including pastries, chocolate and soft drinks, is served only twice a week. Healthier green-labelled foods such as sushi , sandwiches, corn and watermelon, however, are available every day. In some schools, students have a choice of up to 89 foods to choose from, including popcorn and rice. South Africa Most of South Africa's schools do not serve meals at all. Classes end at 1:30pm and students get their own lunches. Many students bring food from home, usually sandwiches. Fast food and fried food sell the best among students, which has led to a rise in _ among children. But as more people began to realize the fact that being too fat may cause different diseases, some schools in towns have led the way towards... Question: The article is written for _ . Options: A: parents B: schoolmasters C: students of your age D: nutritionists

I'm taking a test and have to guess the right answer to the question after the article. Article: A study shows that nearly ninety percent of teens report that they have tried alcohol. That's an increase of 23 percent in just four years! Each year, 1.1 billion cans of beer are drunk by students aged 15-19 years old. Beer is the most common alcoholic drink among teens--81 percent of the drinkers had tried it. Beer is followed by wine with 63 percent, hard liquor with 53 percent and wine coolers with 35 percent. When the young people are asked why they drank, the most common answer is that drinking is "something to do". If a teen's parents drink alcohol, the teenager is more likely to start drinking at an early age. Also, tens see all of their friends drinking alcohol so they think it is the must-to-do thing. Peer pressure is probably the hardest thing teens have to deal with. What's more, teens often drink alcohol because it makes them feel older and cooler. Researchers asked 56,000 students about their drinking habits and grades, to see how drinking might affect their grades in school. The results seem to be clear. Students who got a C level or lower tend to use three times as much alcohol as those who got B's or A's. Alcohol use can be deadly. About 8,100 young people are killed per year in alcohol-related accidents. Eight young people die per day as a result of a drunk-driving accident. Between 50 and 65 percent of all teen suicides occur after the young people drink. So you see, drinking the alcohol doesn't always end up with a good time. The next time you try to push someone to drink or someone tries to push you to drink, please remember this. One drink can set the habit for life. Why not throw it away? Question: The passage was written mainly to _ . Options: A: show the bad effect of drinking alcohol B: show how many teenagers drink alcohol C: tell teenagers not to try alcohol D: tell the reasons why teenagers drink alcohol.
