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: Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school . Now, researchers report that short people--at least in the past--were also more likely to die at a younger age than their taller peers. Their study, published in the Journal of Epidemiology and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal remains from an archaeological site in northeastern England , YC dating from the 9th century to about 1850 . About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased. "This study provides evidence from an archaeological sample that long bone length is connected with age at death--those with smaller bones tend to die younger," according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues . While it is not clear why short stature might be linked to earlier death , the researchers point out that height is _ of childhood nutrition, which may have long-lasting effect on health . "Mechanism for height-mortality associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature mortality in women," Gunnell and colleagues write . "However, short bones, it would appear, have always been a marker of a short life," the authors conclude. Question: Short stature may be caused by _ . Options: A: less childhood nutrition B: heart disease C: some illnesses D: high blood pressure

I'm taking a test and have to guess the right answer to the question after the article. Article: China has a long tradition of respecting education. But its present education is not that respectable. According to the Hurun Report, which conducted one-on-one interviews with 980 wealthy Chinese people with net assets of more than 60 million yuan ($9.5 million) in 18 mainland cities from May to September, about 14 percent of them said they had either already moved overseas or had applied to do so, and another 46 percent said they planned to emigrate within three years. All cited the higher-quality education available for their children overseas as the reason. Such a mindset has resulted in a growing number of Chinese students studying abroad. To be fair, our primary and high schools are a leader in content throughout the world. The Program for International Student Assessment last year offered a feather in the cap for our education. Participating in the program administered by the Organization for Economic Cooperation and Development, teenagers in Shanghai were far in advance of their peers from 64 countries, including the United States, in reading literacy, mathematics and science. So why does education in this country leave so many wealthy parents cold? Children in China have no say in what they learn. They normally learn by rote and are forced to study the subjects that help them in examinations for a school of a higher grade, especially the college entrance exams. Studies conducted by the China Youth and Children Research Center show that more than half of Chinese secondary school students study overtime and they don't get enough sleep. And more than 70 percent of students in primary and middle schools take after-school tutoring classes, which is considered a heavy burden on children. And this situation turns many parents into demons like "Wolf Father" Xiao Baiyou in Guangdong province, who supported his children's learning with verbal abuse and physical violence. Xiao doesn't pale in comparison to Tiger Mother Amy Chua in the United States. He is satisfied with his parenting skills, as he... Question: What is the author's opinion of "Wolf Father" and "Tiger Mother" parenting style? Options: A: Supportive. B: Satisfactory. C: Stimulating. D: Scary.
