New items developed for automobiles in the 1997 model year included a safer air bag, which, unlike previous air bags, eliminated the possibility that a burst of smoke would appear when the bag inflated, and making an already terrified passenger think the car was on fire.
这个题目我看有点意思 A的话是想让making和elminated并列 一起修饰which而which 在这里指的是a safer air bag 大家试想下a safer air bag 能使客人产生车着火的感觉吗 逻辑上不同
B的话更离谱 大家仔细体会下意思 so that是因此的意思 eliminated the possibility that a burst of smoke would appear when the bag inflated 能导致顾客产生车着火的感觉吗 也说不通 并且it指代不明确 不知道指的是前面的句子还是bag 还是somke还是possibility
