(D) to lead to anincrease of 55 percent in delays at airports, and prompted

(E) leading to a55-percent increase in delays at airports and prompting

正确答案是E.大全上的这题和og12 94相同，不晓得B为什么不行，og上的解释是：

the phrase 55 percent more delays is not as clear as the phrase a 55 percent increase in delays


我不明白为什么就没有E项清晰明了了，请NN指教，谢谢：）
