I'm taking a test and have to guess the right answer to the question after the article. Article: Perhaps it is hard to imagine that a bad tooth could be deadly. But doctors in the Washington area say a twelveyearold boy died last month of a tooth infection that spread to his brain. They say it might have been prevented if the boy had received the dental care he needed. Experts at the National Institutes of Health say good dental care should start at birth. They say breast milk is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. When baby's teeth begin to appear,you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies,and use them very gently. The use of fluoride to protect teeth is common in many parts of the world. This natural element is often added to drinking water supplies. The fluoride mixes with enamel ,the hard surface on teeth,to help prevent holes,or cavities from forming. But the American Academy of Pediatric Dentistry points out that young children often swallow toothpaste when they brush their teeth. The group notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully supervised when they brush their teeth. And only a small amount of fluoridated toothpaste,the size of a green pea,should be used. Parents often wonder what effects sucking a thumb or sucking on a pacifier might have on their baby's teeth. Dental experts generally agree that this is fine early in life. The American Academy of Family Physicians says most kids stop sucking their thumbs by the age of four. If it continues,the group advises parents to talk to their child's dentist or doctor. It could influence the correct development of permanent teeth. Question: The boy with a bad tooth died because _ . Options: A: his tooth disease was very deadly B: the doctor refused to treat him properly C: he didn't receive timely treatment D: something was wrong with his brain

I'm taking a test and have to guess the right answer to the question after the article. Article: The snow cap of Mount Kilimanjaro, famous in literature and beloved by tourists, initially formed some 11,000 years ago, but will be gone in two decades, according to researchers who say the ice fields on Africa's highest mountain shrank by 80 percent in the past century. Lonnie G. Thompson,one professor from Ohio State University, said measurements using modern navigation satellites show that the oldest ice layers on the famous mountain were deposited during an extremely wet period starting about 11,700 years ago.The mountain appears in literature, most notably Ernest Hemingway's "The Snows of Kilimanjaro" and some ancient beliefs in Africa hold the mountain to be a sacred place. But a temperature rise in recent years is destroying the 150-foot-high blocks of ice that gave Kilimanjaro its unique white cap."The ice will be gone by about 2030," said Thompson. The disappearing ice already has reduced the amount of water in some Tanzanian rivers and the government fears that when Kilimanjaro is bald of snow the tourists will stop coming. "Kilimanjaro is the number one foreign currency earner for the government of Tanzania," said Thompson. "It has its own international airport and some 20,000 tourists every year. The question is how many will come if there are no ice fields on the mountain." Africa was not alone in the global drought. Thompson said other records show that civilizations during this period collapsed in India, the Middle East and South America. Researchers put markers on the ice field blocks in 1962 and Thompson said measurements using satellites show the summit of the ice has been lowered by about 56 feet in 40 years. The _ of the ice also has moved back more than six feet in the past two years, much smaller than before. "That's more than two meter's worth of ice lost from a wall 164 feet (50 meters) high," said Thompson. "That's an enormous amount of ice." Question: According to Thompson, the disappearing of the snow may mainly influence _ . Options: A: the local water supply B: the local tourism C: the weather in the surrounding areas D: the government foreign currency exchange

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: When different species of birds flock together, their flight formations are determined by social dynamics both between and within species. New research from the Universities of Cambridge and Exeter reveals for the first time that, contrary to current models used to explain the movement of flocks, the differences between bird species and social relationships between individuals play a critical role in determining the dynamics of mixed-species flocks. The unified behaviour of bird flocks has puzzled scientists for hundreds of years. One naturalist from the turn of the century even suggested telepathy may be involved. There have since been more logical explanations, including mathematical models that show that repeated interactions among individuals following simple rules can _ coordinated group movements. However, these models usually rely on the assumption that individuals within groups are identical and interact independently, which may not reflect reality. Jolle Jolles, a PhD student at the University of Cambridge's Department of Zoology and author of the paper, said:"Spectacular collective behaviour can be found in a large range of animal species, and we now know that often these complex coordinated group movements may be the result of individuals following simple rules. However, rarely are the individual characteristics and social relationships within them taken into account. Our research highlights that these striking displays of group behaviour are much more complex." By analysing high-resolution photographs of mixed flocks of rooks and jackdaws (both from the corvid family), the researchers found that rather than individuals interacting in a consistent fashion throughout the flock, interactions depended on social dynamics between the different species as well as relationships within a species. The researchers discovered that birds prefer to fly close to members of their own species, and that the larger and more dominant rooks take the lead by flying near the front of flocks. Additionally, the... Question: According to Jolle Jolles, what are seldom considered about coordinated group movement? Options: A: Individual characteristics and social relationship between them B: Repeated interactions among individuals and social dynamics C: Telepathy and social relationship between them D: The structure of groups and the varieties of species
