[지문]
Downtown Greensborough is a major financial center, in which many citizens either drive or rely on public transportation to get to work. This setup has led up to a spate in the number of pedestrians who have been struck and killed by vehicles. In an effort to curb the number of pedestrian-related fatalities, Greensborough has installed speed reduction signs at the six city intersections in which the highest numbers of fatalities have occurred in the last year. The Greensborough city government predicts that the number of pedestrian fatalities will significantly decrease once the speed reduction signs have been installed.
Q. Which of the following, if true, most strengthens the validity of the conclusion?
Select the answer.
A) Some of those who drive to work in downtown Greensborough have a valid driver’s license.
B) The number of annual pedestrian fatalities outside the downtown area is far less than in the downtown area.
C) The six intersections in which the signs are installed are responsible for a majority of pedestrian deaths in downtown Greensborough.
D) The new speed reduction signs will be in neon orange and prominently placed.
E) Red light cameras, which are used to catch motorists running red lights, were installed yet the number of pedestrian fatalities did not decrease.
