Q23: GWD-11-33

After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.

A.      tested that could eventually propel aircraft anywhere in the world within two hours or help

B.      tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help

C.      tested, eventually able to propel aircraft anywhere in the world within two hours, or helping

D.     tested, and it eventually could propel aircraft anywhere in the world within two hours or helping

E.      tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help

虽然BCD的动词都不平行不能选，E选项could和have the capability重复，只能选A。
但是请问A选项的that从句，可以不与先行词engine紧挨着而被tested隔开吗？

不知道你是否读过Manhattan SC分册
第12章写明Modifier有四种情况可以不满足靠近原则
第二种就是本例，即把短谓语提前，靠近主语，而把长修饰语放到后面，目的是美观、可读性强；
正常语序是这样：
a new type of jet engine that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit is being tested.

是不是看起来很痛苦？

再给你一个例句

•        A new CEO has been hired who will transform the company by decentralizing authority to various division heads while increasing their accountability through the use of public scorecards.
