感觉B紧跟着cost, 修饰起来更清晰吧，至于楼上的 修饰了is projected...不明白......我觉得by the end of the decade是修饰了is projected 前面的所有东西吧，就是主语。 这个就是opening modifier吧。所以可能by the end of the decade只是想修饰cost而已。所以C 修饰了整个的主语就不对了吧

By the end of the decade 修饰对象错了。。修饰了“ is projected”，而逻辑上应该修饰“**的成本应该是多少”...
好像说得不是很让人明白。。换句话讲，is projected应该是当前发生的事情，而不是by the end of the decade发生的事情。
