Read the following article and select the best answer. Article: Inprefix = st1 /Kansas City,Missouri, a computer helps fire fighters. The computer, which works very fast, has information about all the 350,000 street addresses in the city. Within two or three seconds after a call is received, the computer provides necessary information for the fire fighters. The information is then sent to them by radio from the computer centre in the City Hall. The exact place of the burning building and its size, type and any other details are clear to them. TheKansas Citycomputer system also has a medical record of each of the city's 900 fire fighters. This kind of information is especially useful when a fire fighter is injured. With the information, doctors at hospital can treat the injured fire fighters more quickly and easily. The fire fighters themselves greatly appreciate the computer's help. They know about possible danger ahead of them and can prepare for it. Many times the computer information helps to save lives and property . Sometimes the lives are those of fire fighters themselves. Mike Horan, a fire fighter captain, says, "I feel as if the computer is watching over me to help me if I get hurt." Question: Why can the doctors treat the fire fighters quickly and easily? - The hospital has a very good computer. - The fire fighters can know about possible danger early. - The computers can prepare everything for them. - Medical records in the computers help them a lot.
Medical records in the computers help them a lot.

Read the following article and select the best answer. Article: Global warming and changing climatic conditions are triggering disease epidemics in wildlife around the world, reports a famous team of ecologists and epidemiologists in the Friday June 21st issue of Science. "What is most surprising is the fact that climate sensitive outbreaks are happening with so many different types of pathogens ----viruses, bacteria, fungi, and parasites----as well as in such a wide range of hosts including corals, oysters, terrestrial plants, birds, and humans, " says lead author Drew Harvell of Cornell University. "This isn't just a question of coral bleaching for a few marine ecologists, nor just a question of malaria for a few health officials---the number of similar increases in disease incidence is astonishing," says coauthor Richard Ostfeld from the Institute of Ecosystem Studies in Millbrook prefix = st1 /New York. "We don't want to be alarmists, but we are alarmed." The team documented examples of viruses, bacteria, and fungi associated with diseases that develop more rapidly with slight rises in temperature. Many vectors of disease such as mosquitoes, flies, and rodents, as well as the viral, fungal, and bacterial pathogens are highly temperature and moisture sensitive. As temperature increases, _ are likely to spread into new areas and may have potentially devastating effects on wildlife populations that have not been previously exposed. Reproduction, growth, and biting rates of insects all go up with increases of temperature. Winter is the limiting time for many pathogens, killing back populations each year. With milder winters, this population bottleneck may be removed for many species. Warmer, longer summers also mean that the period of time of disease transmission is longer. Warmer summers may increase host susceptibility to disease due to thermal stress, particularly in the oceans. Marine bacteria and fungal growth rates are positively correlated with increasing temperature. Question: Where can we probably find this passage? In a _ . - Book - magazine - textbook - dictionary
