More pedestrian injuries occur at crosswalks marked by both striping on the roadway and flashing lights than occur at crosswalks not so marked. Obviously these so-called safety features are a waste of taxpayer money. The reasoning in the argument is most vulnerable to criticism because the argument
A: takes for granted that crosswalks with both striping and flashing lights have no other safety features
B: fails to consider that crosswalks marked by both striping and flashing lights are marked in this way precisely because they are the most dangerous ones
C: presumes that there are less expensive features that will reduce the number of pedestrian injuries just as effectively as striping and flashing lights
D: takes for granted that safety features that fail to reduce the number of injuries are a waste of taxpayer money
Choose A, B, C or D as your solution.
