Because these galaxies' mass is spread out over larger areas, they have far fewer stars per unit volume than do conventional galaxies.
A:they不能指代studies吗?
選項C ,老師講解不對 (副词只能修饰动词,不能修饰名词)
the investors's speculation that... === the investors speculate that ...
先說D選項: 加了and , 說明了兩件事 1: findings lend support to the theory of black hole 2: many of the 100 billion other galaxies estimated to exist in the universe. 兩件事沒有相關性

two-year level中两年做定语,变成了level的固有性质;而in two years则是做状语,修饰整个句子。在这题中,做状语更合适。
D 錯誤 :his garden in a vase. in a vase 是 garden的定語 , 花園不會在花瓶裡. 只會花瓶出現在花園裡
