The passage does not discuss the number of fatalities. It only speaks to a significant reduction in fatalities than the previous year. E states that the number of fatalities was not abnormally high to begin with, however, the passage only mentions that there was a significant reduction. D seems to weaken because it speaks to enforcement reducing the fatalities not the reduction of the highway speed limit.
