newspaper:
“Last year when Washington County received a special appropriation for improving highway safety, it spent all those funds to straighten sections of certain county roads. Unfortunately, the number of traffic accidents in the county was actually higher than in the previous year. Although Adams County received a smaller appropriation for improving highway safety, it hired more police officers and enforced traffic laws more strictly. Last year Adams County reported 15% fewer traffic accidents than during the previous year. Since money for improving highway safety throughout the state is limited, we can achieve greater success with less expenditure by using all such funds for stricter enforcement of speed limits.”
呵,請高人指點我一下錯誤在哪好嗎
