prep 113 里passage的用法

113. The 151 member governments of the World Bank are expected to increase the bank’s funding by $175 billion, though some United States legislators cite an obstacle to congressional passage being the concern that the bank’s loans will help foreign producers compete with American businesses.

A. an obstacle to congressional passage being the concern

B. a concern as an obstacle to congressional passage

C. as an obstacle to congressional passage the concern

D. the concern, an obstacle to congressional passage

E. as an obstacle for Congress to pass it the concern

D中的passage用法很困惑，开始选E，IT是错的，可是D，怎么解释？

谢谢大家

应该是C

原文原来的结构应该是cite a concern....as an obstacle to congrational passage.的结构吧

因为that修饰concern太长，这里调整了一下顺序吧

我是看了半天才觉得应该是这样的

主要还是要理解原文的意思，否则是看不出所以然：）
