30. GWD-31-Q30

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.

我选的是E，答案是B

另外，E有什么问题？

1.C的问题是，同位语没有紧邻修饰对象，造成修饰模糊。对于MM说的原则，我认为不可取，一切还是要从逻辑意义出发考虑。但是全句划线的情况倒装的正确率MS蛮高。

2. cost说是什么的成本时，用cost of. 说明cost的属性。cost to do没有这种说法。OG有两例都说了这个问题。to the United States 这里的to是介词，表示一个范围，这也就说明了为什么A的所有格是错的。

E的问题是，is estimated at 不对，应该是 is estimated to be；另外by the end of the decade 位置导致修饰模糊，不是它本来修饰全句的意思。
