ysl246

(A) Unlike in other transportation industries, there are no minimum standards set by government or industry for qualifying for being

(B) Unlike other transportation industries that have minimum standards set by government or industry, there are none for qualifying to be

(C) Although the government or industry usually sets minimum standards for transportation industries, no such one has been set for qualifying as to being

(D) Although the government or industry usually sets minimum standards for transportation industries, no such standard has been set for qualifying to be

(E) Although there are usually minimum standards set by government or industry for transportation industries, there is none for qualifying and being

考点不在sets而在于unlike A, B do中A,B需严格对称，立刻排除A,B项，

E中there be sth done,错，

C中one不如[n.]standard好，for qualifying as to being也不对

恩。。。但是不考虑这道题本身的话，or后面应该加谓语单数把？
