30. GWD-31-Q30 The United States petroleum industry’s cost to meet environmental regulations is projected at ten percent of the price per barrel of refined petroleum by the end of the decade
A. The United States petroleum industry’s cost to meet environmental regulations is projected at ten percent of the price per barrel of refined petroleum by the end of the decade. B. It is estimated that by the end of the decade the cost to the United States petroleum industry of meeting environmental regulations will be ten percent of the price per barrel of refined petroleum. C. By the end of the decade, the United States petroleum industry’s cost of meeting environmental regulations is projected at ten percent of the price per barrel of refined petroleum. D. To meet environmental regulations, the cost to the United States petroleum industry is estimated at ten percent of the price per barrel of refined petroleum by the end of the decade. E. The United States petroleum industry’s cost by the end of the decade to meet environmental regulations is estimated at ten percent of the price per barrel of refined petroleum. --------------------------------------------------------------------------------------------------------- 正确答案为B 不解的是为何需要把原选项的“projected"改为”estimated“ 这一题cost以被动方式描述就不好么？ 另外B中的用法cost to the United States petroleum industry of meeting environmental regulations总觉得别扭，是否用限定性定语从句来修cost更好些？ 选D有何错误？ 谢谢斑斑~

求指导
B 中 “cost to ...industry of meeting "
是什么结构呢？
B.It is estimated that (by the end of the decade) the cost (to the United States petroleum industry of meeting environmental regulations) will be ten percent of the price (per barrel of refined petroleum).
可以简化为It's estimated that the cost will be ten percent of the price.
不知道我表述的到不到位？
关于the cost (to the United States petroleum industry of meeting environmental regulations)，后面的纯粹是后置定语。
