２７、The following appeared in a popular health and fitness magazine.
"A ten-year study of a group of 552 men from Elysia showed that long-term consumption of caffeinated black tea was associated with a much lower risk of stroke. Of these men, those who drank more than three cups of black tea a day had a 70 percent lower risk of stroke than those who drank no tea. These results suggest that health-conscious people should consume at least three cups of black tea a day, beginning early in life."

２８、The following appeared in a report of the Committee on Faculty Promotions and Salaries at Elm City University.
"During her seventeen years as a professor of botany, Professor Thomas has proved herself to be well worth her annual salary of $50,000. Her classes are among the largest at the university, demonstrating her popularity among students. Moreover, the money she has brought to the university in research grants has exceeded her salary in each of the last two years. Therefore, in consideration of Professor Thomas’ demonstrated teaching and research abilities, we recommend that she receive a $10,000 raise and a promotion to Department Chairperson; without such a raise and promotion, we fear that Professor Thomas will leave Elm City University for another college."

２９、The following appeared in a newsletter distributed at a recent political rally.
"Over the past year, the Consolidated Copper Company (CCC) has purchased over one million square miles of land in the tropical nation of West Fredonia. Mining copper on this land will inevitably result in pollution and environmental disaster, since West Fredonia is home to several endangered animal species. But such disaster can be prevented if consumers simply refuse to purchase products that are made with CCC’s copper until the company abandons its mining plans."

３０、The article entitled ’Eating Iron’ in last month’s issue of Eating for Health reported that a recent study found a correlation between high levels of iron in the diet and an increased risk of heart disease. Further, it is well established that there is a link between large amounts of red meat in the diet and heart disease, and red meat is high in iron. On the basis of the study and the well-established link between red meat and heart disease, we can conclude that the correlation between high iron levels and heart disease, then, is most probably a function of the correlation between red meat and heart disease. The following appeared as a letter to the editor of a national newspaper.

３１、"Your recent article on corporate downsizing* in the United States is misleading. The article gives the mistaken impression that many competent workers who lost jobs as a result of downsizing face serious economic hardship, often for years, before finding other suitable employment. But this impression is contradicted by a recent report on the United States economy, which found that since 1992 far more jobs have been created than have been eliminated. The report also demonstrates that many of those who lost their jobs have found new employment. Two-thirds of the newly created jobs have been in industries that tend to pay above-average wages, and the vast majority of these jobs are full-time."
*Downsizing is the process in which corporations deliberately reduce the number of their employees.

３２、According to a poll of 200 charitable organizations, donations of money to nonprofit groups increased by nearly 25 percent last year, though not all charities gained equally. Religious groups gained the most (30 percent), followed by environmental groups (23 percent), whereas educational institutions experienced only a very small increase in donations (3 percent). This poll indicates that more people are willing and able to give money to charities but that funding for education is not a priority for most people. These differences in donation rates must result from the perception that educational institutions are less in need of donations than are other kinds of institutions.

３３、A new study collected data that shows that people who snore are more likely to gain weight than are people who do not snore. It is well known that many people who snore also stop breathing frequently during the night for a few seconds, a condition called sleep apnea. The interruption of breathing wakes the person---often so briefly that the waking goes unnoticed---and can leave the person too tired during the day to exercise. Anyone who snores, therefore, should try to eat less than the average person and to exercise more

３４、The following appeared in the editorial section of a local newspaper.
"The librarians in our town’s school system have reported that the number of trips that our students make to their school library on a voluntary basis has decreased significantly in recent years. For example, the average seventh-grade student visited the school library five times last year, but four of those visits were part of required classroom activities. This shows that our students are reading less than in the past. To address this problem, our town needs to improve the atmosphere of the libraries so that they will be comfortable places in which to work. If students view the libraries as uncomfortable, then they are unlikely to want to spend much time there."
