问题 We learn from the first paragraph that two systems of automated highways______.
A special-purpose lane system is probably advantageous in that______.

选项 A、it would require only minor changes to existing highways
B、it would achieve the greatest highway traffic efficiency
C、it has a lane for both automated and partially automated vehicles
D、it offers more lanes for automated vehicles

答案B

解析 细节题。根据第一段最后一句:A special-purpose lane system would require more extensive physical modifications to existing highways,but it promises the greatest gains in freeway capacity.特别目的车道系统要求对现有的高速公路进行更广泛的改造,但它会使高速公路获得最大的能力。由此可知B为止确答案。
