不需要的。一定要从语法机构的底层逻辑来看待这个问题。我们一般管介词短语也叫介宾短语。这个意思就是介词后面一定加名词（所有的宾语都是名词性的）。名词是没有所谓逻辑主语的概念的。譬如，table就没有主语，只有动作才有主语。同时，英语中也规定，如果想给动名词添加主语的话，需要用所有格的形式，例如：people's preparing。

另外，ABC里边in preparation/preparing for ...用的是介宾短语做状语，没有逻辑主语的概念，所以不能依据这个来看句子主语来排除选项。
为地震做准备，不是为预测做准备
E： To prepare for a major earthquake ， prepare的对象应该是prediction而不是earthquake, 杀掉
剩下BC只有C的 to identify和后面未划线部分的and to pinpoint 结构和语义平行
d，prepare的逻辑主语只能是California office，不能是a satellite
rest of it. The opening phrase claims to describe preparations for a
prediction, whereas the latter part of the sentence indicates that the
preparations are for a predicted earthquake.
the California Office is preparing for a prediction, but later in the sentence it
becomes clear that the preparations are targeted to the aftermath of a
possible earthquake, not its prediction.
