1. 选 B.
B.    wild animals have less total fat than (这里助动词do省略) livestock fed on grain and more of a kind of fat thought to be (less... and more...并列,共同作为have的宾语)(they thought代词they单独出现无指代,改为过去分词)

2. 选 A.   of which 当中的which修饰system,无错误。整个句子是一个大的平行对称结构,Researchers have announced that.... and that.... 也就是announce了两件事情。这里是两个并列的that引导的宾语从句,因此and后面的that不可省略。

2.以前说there be结构不对,是因为there be结构表示的是自然存在的东西,这里的磁场肯定是自然存在的东西,there be结构用在这里就合理了

所以我觉得不能用there be结构排除ABC
