The 19th-century proponents of the school of thought known as mechanism held that life process are not the products of some mysterious life force, but are the same chemical and physical processes that operate in inorganic systems, which is still a subject of debate between biologists today.
(A) systems, which is still a subject of debate between
(B) systems, which are still debated between
(C) systems still debated among
(D) systems, a theory still debated by
(E) systems, a theory still debated between
答案是D，我选的是B。a theory是同位语吗？为什么不在它之后加个is？谢谢！

我解答这道题的思路是这样的，不知道对不对。首先，这句子的主干是“这个理论是当今biologists争论的话题”。我觉得介词between用得不对，要么不用，要么用among，因为between用于两者之间。排除A.B.E 其次，C是缺少逗号的，况且debated的是theory，而不是systems，怎样都有错。
再提一下B，主谓不一致，因为主语是一个理论，不是systems，所以不能用are
再看D，a theory 指的是前面整个句子，后边是一个独立主格结构，是不能出现谓语的，a theory就是debated的逻辑主语。如果非要加is，那就不要用独立主格，改为定语从句。a theory that is still debated by
