Question

@Steph, Happy to help. (B) says, "Uniformity of speeds among vehicles is more important for highway safety than is a low average highway speed." (B) is the correct answer because it provides us with an explanation that gives us a reason to think that that raising speed limits would increase safety rather than decrease it. Increasing speed highway speed limits would help bring the current drivers who are driving under the speed limit up to the speed of current speeders, so overall the highway will have a greater percentage of cars driving at uniform speeds. Given what (B) says, we know this would make the highway safer. Does this make sense? Let us know if you have any other questions!
