181The following appeared as an editorial in a health magazine.
"Clormium 5 is an odorless, tasteless, and generally harmless industrial by-product that can enter the water supply. A preliminary study has linked cooking with water containing clormium 5 to an increased incidence of allergies and skin rashes. Tests of the drinking water in several areas have revealed the presence of clormium 5. Although it is possible to remove clormium 5 from water, the costs of routine testing and purification are higher than many communities can afford. Therefore, in order to prevent allergies and skin rashes, communities that cannot afford to rid their drinking water of clormium 5 should replace drinking fountains in public buildings, such as schools and libraries, with bottled-water coolers."
182Allergies are an overreaction of the immune system to certain stimuli. One view is that allergies can develop as the result of childhood exposure to certain irritants, such as dust or animal dander, while the immune system is not yet mature. Another view is that exposure to particular bacteria early in childhood actually triggers the proper development of the immune system, and that limiting exposure to these bacteria through excessive hygiene can cause children's immune systems to overreact to certain irritants later on. A new study supports the second view: children who are washed especially frequently and whose parents clean their homes especially frequently are more likely to develop allergies than are other children. So in order to reduce the incidence of allergies in children and adults, parents should not limit children's exposure to irritants or bacteria.
183The following appeared in a letter to an editor.
"In many countries, wood is the primary fuel used for heating and cooking, but wood smoke can cause respiratory and eye problems, and extensive use of wood causes deforestation, a major environmental problem. In contrast, charcoal, made by partially burning wood in a controlled process, is a fuel that creates less smoke than wood does. Moreover, although charcoal costs slightly more than wood, less charcoal is needed to produce the same amount of heat. Therefore, people who use wood as their primary fuel can, without experiencing economic hardship, switch to charcoal and can thereby improve their health and preserve the environment."
184The following appeared in a memo from the business manager of Medicine, Inc., a local drugstore.
"Most business analysts for the drugstore industry have stated that even when a nation's economy is weak, drugstores' profits are unlikely to decline appreciably. While consumers might put off some kinds of purchases when the economy is slow, prescription and over-the-counter drug purchases are dictated by consumers' health needs, which are independent of the economy. Therefore, Medicine Inc. is likely to continue to have increasing profits and should plan to open an additional drugstore next year."
185The following appeared in a memo written by the head of the Gorham School.
"Our school cafeteria should make changes in the lunches that it serves in order to improve the health of our students. Several teachers and I have observed that students who eat these meals tend to eat the main course and the dessert, but seldom finish the vegetable portion. This pattern means that students are missing the vital nutritional benefits of fruits and vegetables, which are typically rich in vitamins and minerals. Therefore, the school cafeteria should serve larger fruit and vegetable portions along with smaller main course and dessert portions. This change will be effective because, according to research conducted at the Rose Children's Hospital, children eat the same amount of food served to them — about 55 percent, on average — no matter what the main course is."
186The following appeared in the letter to an editor of a Myrian newspaper.
"Under Governor Winslow's leadership over the past four years, Myria has enjoyed unprecedented prosperity. Average wage increases this year are higher than they have been at any time since the 1970's, the number of people who report being unemployed has decreased by 10 percent, and construction of new homes is up by one third. In contrast, over the past four years Governor Winslow's opponent, Mr. Homer, has been mayor of a city in which only a small number of new businesses have opened. If Myrians want another four years like the past four years, they should reelect Governor Winslow."
187The following appeared in a memo from a member of the Clark City School Board.
"Mason Elementary School is faced with a shortage of classroom space. At the same time, parents in our district are increasingly expressing the desire to see improvements in their children's reading abilities. Therefore, we should reduce the number of physical education classes at Mason Elementary and convert part of the gymnasium to class-room space. The school will gain the additional space for classrooms without the cost of extending the building and can use the time that students would have spent in physical education classes to provide more reading instruction. This plan will lead to improvements in students' reading skills."
188The following appeared in a memo to managers of Christine's, a chain of craft stores.
"Several major newspapers have recently run articles noting an increased interest in pottery. The number of potters in this country has risen by eighteen percent in the past five years, and pottery is particularly gaining popularity on college campuses. In order to take advantage of these trends, Christine's should immediately begin carrying a larger volume of pottery supplies. Since several of our stores have recently experienced a decrease in sales of painting supplies, all store managers should reallocate shelf space from the painting area for the display of pottery. Stores should display posters showing pottery that is designed to appeal to college-age individuals. These actions will undoubtedly increase our profits dramatically."
189The following appeared in a newsletter about health published in the country of Sauria.
"According to Sauria's leading nutritional experts, a diet high in complex carbohydrates, and low in fat is optimal for good health and longevity. Because this was the diet of the people who lived in ancient Sauria, one would expect them to have had long and healthy lives. Yet the mummified remains of Sauria's ruling classes from two to three thousand years ago show the existence of many medical problems among the ancient Saurians, including dental problems, elevated blood pressure, obesity, heart disease, and early mortality. Clearly, the diet of the ancient Saurians was responsible for these problems. The high incidence of high blood pressure, obesity, and heart disease in Sauria today even among those who have tried low-fat, high-carbohydrate diets further proves that Sauria's leading nutritional experts are wrong."
190The following appeared in a newspaper published in the state of Celera.
"Speed limits on our state's highways should be eliminated in order to increase our state's prosperity. Because greater speed means more efficient travel, commercial deliveries will be faster, increasing business profits. Elimination of speed limits will also make driving more attractive to motorists, so that more people will use the highways, providing more highway toll revenues for the state. At the same time, safety on our highways will not be affected: daytime speed limits were eliminated last year in the western states of our country, and no significant increase in the number of accidents in these states has been reported."

181 Clormium 5是一种能够进入供水系统的无臭无味且基本无害的工业副产品。一项初步调查发现用含有Clormium 5的水做饭与过敏和皮炎发病率的增加有关。在一些地区对于饮用水的检测发现了Clormium 5的存在。尽管我们可以从水中除去Clormium 5，日常检测和净化的花费要高于很多社区所能承受的值。因此，为防止过敏和皮炎，那些负担不起从水中除去Clormium 5的花费的社区应该把公共建筑比如学校和图书馆的饮水龙头替换成瓶装水冷却器。
182过敏是免疫系统对某种刺激的过度反应。一种观点认为过敏可能会由于儿童时期免疫系统还不成熟的时候接触了某种刺激物比如灰尘或动物皮屑而导致。另一种观点认为幼年时接触特定的细菌实际上能促进免疫系统的正常发育，通过过度的卫生手段切断与这些细菌的接触将会导致儿童的免疫系统以后将对某种刺激物反应过度。一项新的研究支持了第二种观点：洗澡过于频繁的儿童和其父母打扫房间过于频繁的儿童比其他儿童更容易患过敏症。因此为减少儿童和成人过敏发病率，家长不应该限制儿童对刺激物或细菌的接触。
183在很多国家，木材是取暖和做饭的主要燃料，但燃烧木材产生的烟能够导致呼吸道和眼部疾患，而且过度使用木材会导致林木资源枯竭这一严重的环境问题。相比而言，通过一种受控制的流程使木材不充分燃烧而产生的木炭是一种产生的烟雾比木材少的多的燃料。而且，尽管木炭比木材稍微贵一些，但产生同等热量所需的木炭比较少。因此，仍以木材为主要燃料的人们可以不会有任何经济障碍地转向木炭，因而能够提高他们的健康水平并保护环境。
184多数药品商店的商业分析师指出即使当一个国家的经济低迷的时候，药店的利润也不太可能明显下降。经济萧条时消费者可能放弃某些物品的消费，而处方药和非处方药的消费由消费者的健康需求决定，而这不取决于经济。因此，Medicine Inc.很可能继续保持盈利的增长，并且应该计划在来年开设一家新药店。
185我们的学校食堂应该对于它所提供的午餐服务进行改革来提高我们学生的健康。一些教师和我观察到在这里吃午餐的学生倾向于吃主菜和甜食，但很少把蔬菜吃完。这一习惯意味着学生没有摄取到水果和蔬菜的营养成分，这通常包含有大量维生素和矿物质。因此，学校食堂应该提供更大分量的水果和蔬菜并减少主菜和甜食的量。这种改革将会十分有效，因为根据Rose Children's Hospital所作的研究，不论主菜是什么，儿童都将会吃掉同等数量的所提供的食物--平均而言大约55%。
186过去四年中在州长Winslow的领导下，Myria经历了空前的繁荣。今年平均工资提高，而且比1970年以来的任何一年都要高，报告失业的人数下降了10%，新住房的建造增加了三分之一。相比之下，过去四年中Winslow的竞争对手Homer出任了另一个市的市长，那个城市只开展了很少的新型商业。如果Myria的居民希望未来四年和过去四年一样，他们就应该再次选举Winslow。
187 Mason小学面临着教室空间短缺的问题。同时，我们区的家长对于看到他们的孩子阅读能力提高的愿望越来越强烈。因此，我们应该减少Mason小学体育课的数量，把部分体育场馆改造成教室。学校无需花费资金扩建校舍就可以获得更多的教室空间，并且可以把学生原本花在体育课的时间用于提供更多的阅读课程。这一计划将会带来学生阅读能力的提高。
188一些大报最近刊登文章指出对于陶器兴趣的增长。过去五年中全国陶工的数量增加了18%，并且陶器在大学校园得到了特殊的青睐。为利用这一潮流，Christine's应该马上开始提供大量陶器。由于我们的若干商店最近绘画的销量下降，所有的店主都应该重新安排货架空间，把绘画的货架用于展示陶器。商店应该张贴能够吸引在校年龄人群的陶器的招贴画。这些举措无疑将会显著增加我们的盈利。
189根据Sauria的权威营养专家的看法，碳水化合物含量高而脂肪含量低的饮食对于健康和长寿是最为有利的。由于古代Sauria的居民所吃的就是这类饮食，我们可以推测他们应该健康而且长寿。然而一两千年前Sauria统治阶级的木乃伊残骸显示古代Sauria人存在很多疾病，包括牙齿疾患，高血压，肥胖，心脏病和早夭。显然，古代Sauria人的饮食是这些疾患的原因。今天Sauria那些既便尝试了低脂肪高碳水化合物饮食的人中也存在的高血压，肥胖和心脏病的较高发病率进一步证明了Sauria权威营养学家是错误的。
190本州高速公路的限速应该被取消以促进本州的繁荣。由于更高的速度意味着更高效的交通，商业物流将会更快捷，从而增加商业利润。限速的取消同样也会使驾驶对于司机更有吸引力，因而更多的人将会使用高速公路，为本州带来更多的路费收入。同时，高速路的安全并不会受到影响：本国西部州去年取消了白天的限速，那些州上报的事故数量并没有显著增加。
