   The following appeared in a letter to the editor of the Balmer Island Gazette.

　“The population of Balmer Island increases to 100，000 duing the summer months. To reduce the number of accidents involving mopeds and pedestrians， the town council of Balmer Island.， should limit the number of mopeds rented by each of the island’s six moped and bicycle rental companies from 50 per day to 30 per day during the summer season. By limiting the number of rentals， the town council is sure to attain the 50 percent reduction in moped accidents that was achieved last year in the neighboring island of Torseau， when Torseau’s town council enforced similar limits on moped rentals.”

 The following appeared in a recommendation from the president of Amburg’s Chamber of Commerce.

“Last October the city of Belleville installed high intensity lighting in its central business district， and vandalism there declined almost immediately. The city of Amburg has recently begun police patrols on bicycles in its business district but the rate of vandalism there remains constant. Since high intensity lighting is apparently the most effective way to combat crime， we should install such lighting throughout Amburg. By reducing crime in this way， we can revitalize the declining neighborhoods in our city.”

 The following appeared as part of an article in a health magazine.

 “A new discovery warrants a drastic change in the diets of people living in the United States. Two scientists have recently suggested that omega －3 fatty acids play a key role in mental health. Our ancestors， who ate less saturated fat and more polyunsaturated fat， including omega －3 fatty acids， were much less likely to suffer from depression than we are today. Moreover， modern societies－－－such as those in Japan and Taiwan－－－that consume large quantities of fish report depression rates lower than that in the United States. Given this link between omega －3 fatty acids and depression， it is important for all people in the United States to increase their consumption of fish in order to prevent depression.”

　The Department of Education in the state of Attra recommends that high school students be assigned homework every day. Yet a recent statewide survey of high school math and science teachers calls the usefulness of daily homework into question. In the district of Sanlee， 86 percent of the teachers reported assigning homework three to five times a week， whereas in the district of Marlee， less than 25 percent of the teachers reported assigning homework three to five times a week. Yet the students in Marlee earn better grades overall and are less likely to be required to repeat a year of school than are the students in Sanlee. Therefore， all teachers in our high schools should assign homework no more than twice a week， if at all.
