　　the following appeared in a newsletter on dental health.

　　a recent research study reported the experience of dentists whose patients had, over a period of five years, regularly used flux dental floss as part of their dental hygiene routine. the report indicates that these dentists had 50 percent fewer cases of gum disease than did dentists whose patients did not use flux regularly. in addition, most of the flux users who were surveyed by their dentists agreed that fluxs mint flavor would encourage people to floss more often. thus, even though flux may cost more than other brands of floss, it is clearly a worthwhile investment for those who want to be assured of healthy teeth and gums.

　　the following appeared in a letter to the editor of the shady village newspaper.

　　commuters are complaining that the rush hour traffic on blue highway between shady village and bright city has doubled their commuting time. some commuters have asked that an additional traffic lane be built, but the recent creation of such a lane on nearby green highway apparently attracted more commuters, judging from the fact that rush-hour traffic jams actually increased there this past winter. to reduce rush-hour traffic on blue highway, a bicycle lane should be added instead of a traffic lane. this approach will succeed because many citizens of shady village are avid bicyclists; 75 percent of respondents to a recent questionnaire distributed there said they would like to bicycle more hours per week than they currently do.
