they 指代不清 首先比较答案, 用and 还是不用and, 如果用and, A, they指代不清,B不是完整句子,C 比较对象不平fossile 和 dinosaur types, 再看DE, E比较对象不平.所以,选择D.. 此类题型 that 不轻易使用 因为前面名词较多 容易混淆 同时 and前面不常加逗号 所以 应该首先怀疑 如果是announced that...and that...这个句子就是并列的,而",and that"就表示这个是非必要成分,是从属的,明显逻辑不对。

1. they指代不清楚 -- paleontologists,fossils,or dinosaurs? 2. was found 时态不正确,被发现的fossils是一个事实,不需要用过去时

2 errors: 1. use of third person pronoun 'they' is ambiguous - fossils or dinosaurs. 2. They announced that X and that Y - latter that is missing in A, 且不需要逗号

主要错误原因在于they指代不清,可能指代paleontologists,fossils或者dinosaurs。故而视作病句,一个小问题是fossils做主语,谓语动词用单数还是复数?

1)-they指代不清,是paleontologists还是fossiles还是dinosaurs. 2)-比较是they 与types比较。
