　　1. A recently issued twenty-year study on headaches suffered by the residents of Mentia investigated the possible therapeutic effect of consuming salicylates.Salicylates are members of the same chemical family as aspirin,a medicine used to treat headaches.Although many foods are naturally rich in salicylates,food-processing companies also add salicylates to foods as preservatives.The twenty-year study found a correlation between the rise in the commercial use of salicylates and a steady decline in the average number of headaches reported by study participants.At the time when the study concluded,food-processing companies had just discovered that salicylates can also be used as flavor additives for foods,and,as a result,many companies plan to do so.Based on these study results,some health experts predict that residents of Mentia will suffer even fewer headaches in the future.

　　2. A recent sales study indicates that consumption of seafood dishes in Bay City restaurants has increased by 30 percent during the past five years.Yet there are no currently operating city restaurants whose specialty is seafood.Moreover,the majority of families in Bay City are two-income families,and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about healthful eating.Therefore,the new Captain Seafood restaurant that specializes in seafood should be quite popular and profitable.

　　3. In an attempt to improve highway safety,Prunty County last year lowered its speed limit from 55 to 45 miles per hour on all county highways.But this effort has failed:the number of accidents has not decreased,and,based on reports by the highway patrol,many drivers are exceeding the speed limit.Prunty County should instead undertake the same kind of road improvement project that Butler County completed five years ago:increasing lane widths,resurfacing rough highways,and improving visibility at dangerous intersections.Today,major Butler County roads still have a 55 mph speed limit,yet there were 25 percent fewer reported accidents in Butler County this past year than there were five years ago.
