(A) Europeans have long known that eating quail sometimes makes
(B) Europeans have long known quail eating is sometimes able to make
(C) Eating quail has long been known to Europeans to sometimes make
(D) It has long been known to Europeans that quail eating will sometimes make（A）
(E) It has long been known to Europeans that quail, when it is eaten, has sometimes made

A固然是对的，但D看起来虽然啰嗦，但和句子后面的形式更为对称~~为什么不选择D呢

首先，根据主动优先原则在同时有主动和被动的情况下，要优先选择主动地形式
其次，D选项前面用的是have long been known to 的完成形式后面却用了will 应该用would
最后，是关于eating quail 和 quail eating, 个人感觉这和中外思维有差距有关。是eating quail 才是人生病，而不是quail eating本身使人生病。
我是这么理解的，非牛人。请大家多多指教。
