A PRT only B RUF only C both PRT and RUF
Write the correct letter, A, B, or C in boxes 7-12 on your answer sheet. [br] It can run on existing roads.

选项

答案 B

解析 原文明显提到只有RUF可以在现有道路上运行(倒数第四段中间“so they can driveoff the rail onto a normal road”),而PRT却不具备这个特征(第五段中间“With PRT,the infrastructure would have to come first”),所以正确答案为B。
