请教曼哈顿上所说的warmup如何辨别（结合ron讲解的prep08.sc2.200）

Many financial experts believe that policy makers at the Federal Reserve, now viewing the economy as balanced between moderate growth and low inflation, are almost certain to leave interest rates unchanged for the foreseeable future.

A. Reserve, now viewing the economy as balanced between moderate growth and low inflation, are
B. Reserve, now viewing the economy to be balanced between that of moderate growth and low inflation and are
C. Reserve who, now viewing the economy as balanced between moderate growth and low inflation, are
D. Reserve, who now view the economy to be balanced between that of moderate growth and low inflation, will be
E. Reserve, which now views the economy to be balanced between moderate growth and low inflation, is

答案是A
viewing the economy..修饰的是谁呢？因为千行语法上说subject,verbing,verb结构中，verbing一律修饰subject,那么subject到底是 financial experts还是policy makers呢？我认为是financial experts。
但是ron是这样说的：(note that "Many financial experts believe that" is a completely disposable "warm-up" and can be disregarded without changing or restricting the grammar of the sentence at all.)  所以这个subject就应该是policy makers了
但是关键是这个所谓的warm up是怎么辨别的呢？（我看曼哈顿上也出现过）

这里很明显是修饰makers的，首先一个问题是那个从句没有结束，只有主语，now结构作为定语修饰makers，更简单的说法是句子层级不一样，处在从句那一级中逻辑主语为该从句的主语，还有一个最简单的判断，不管状语还是定语成分都是就近修饰，如果view部分想修饰前面的提前到句首
