答案

b
当first和firstly作副词用的时侯,如果“用于分开并依次列举所述各点”时,是没有什么区别的,可以替换.e.g.First(ly),I'll mention the advantages,then I'll mention the disadvantages.
但当用于修饰行为动词时,则只能用first.
e.g.I must ask my parents first
When did you first go to the country?
b
翻译 尽管老路确实不是很便捷,然而我还是不会选择新的,因为我并不觉得安全
d
have 是动词,如果不加who的话,一个句子中就有两个谓语动词了
（有问题的话,欢迎讨论,嘿嘿）
