42. Twenty-two feet long and 10 feet in diameter, the AM-1 is one of the many new satellites that is a part of 15 years effort of subjecting the interactions of Earth's atmosphere, oceans, and land surfaces to detailed scrutiny from space.
(A) satellites that is a part of 15 years effort of subjecting the interactions of Earth’s atmosphere, oceans, and land surfaces
(B) satellites, which is a part of a 15-year effort to subject how Earth's atmosphere, oceans, and land surfaces interact
(C) satellites, part of 15 years effort of subjecting how Earth’s atmosphere, oceans, and land surfaces are interacting
(D) satellites that are part of an effort for 15 years that has subjected the interactions of Earth’s atmosphere, oceans, and land surfaces
(E) satellites that are part of a 15-year effort to subject the interactions of Earth’s atmosphere, oceans, and land surfaces

请教各位大侠：
1）为何B的which不能跳跃之前的介词词组而指代AM-1，句子开头就在修饰AM-1，逻辑上应该指AM-1才对。
2）OG解释 presenting the object of the verb subject as a phrase beginning with how and ending with the verb interact produces a sentence that seems to be about how various conditions ract to detailed scrutiny from space. 这个解释我没太看明白，逻辑有问题了？句子最后那个to bla bla我没太看明白什么意思。
3）答案是E
谢谢大家

这里不好呢，因为which前面有个 part 还有 effort都是单数，不能使用单复数的规则去确定哪个是被修饰的，而且加了逗号是non-essential的，不好，这里必须是essential的。

to bla bla bla 是题目啊

恩，no-essential，这个有道理
