(E) resulting in the fact ofdomestic oil prices that are vulnerable to any hints of oil supply disruptionsin the Middle East or to any unexpected growth in consumer demand that might be
这道题的OA是B，但为什么B不是错的呢？
or并列状语省略介词的情况很常见，那么：
to any hints of oil supply disruptions in the Middle East or any unexpected growth in consumer demand that might be这句话有明显的歧义
any unexpected growth极有可能是省略了介词in作 oil supply disruptions的状语啊（和in the middle east并列）
虽然题中有明显的平行提示词any，但还是会有歧义的可能性啊。GMAC究竟在什么情况下忽略介词省略造成的歧义，什么时候把歧义当成错误呢？
谢谢各位NN
