[求助]大全真题18，提问

18.   Many environmentalists believe that the widespread planting of trees, along with the conservation of existing forests, would be one of the surest, easiest, and least expensive ways to begin to halt or even to reverse the buildup of carbon dioxide in the air.

(A) one of the surest, easiest, and least expensive ways to begin to halt or even to reverse

(B) one of the most sure, easy, and least expensive ways to begin a halt or even reverse

(C) one of the surest, easiest, and least expensive ways that would begin halting or even reversing

(D) a most sure, easy, and inexpensive way beginning the halting and even reversing of（A）

(E) the most sure, easiest, and inexpensive way that would begin halting or even reversing

原本选A的，但在REVIEW的时候，突然有这样的想法，the most，是最高级了，最高级应该是独一无二的啊，one of 与最高级有点语义重复的感觉，基于这个考虑，首先就排除了ONE OF的 ABC选项。请大牛指教？？？？？？？？？

“one of the surest, easiest, and least expensive ways ”指的是“各种最可靠、最容易、最便宜的方法”。。没有说最高级就一定是独一无二的啊，比如说下面这个句子：

He's one of the richest men in the world.[引自Longman]
