Once positioned in space, the Bubble Space Telescope will capture light from sources twenty times fainter compared to those that can be detected by ground based instruments.

(B) compared to those they can detect
(C) than that can be detected
(D) than those that can be detected
(E) than those detecting

Ans: D

LZM解释说those指sources，但是为什么还用that呢？

我的看法是 that can be detected by ground based instruments 用來補充說明those.
尤其,未畫線部分有by, 所以不選 e.

that是用来引导定语从句的，和单数复数无关的。

以下是引用海蓝在2003-8-24 21:08:00的发言：

惭愧啊
