还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
in studying。。。。的这句话后面是evidence，所以是evidence在studyding？逻辑不合理，应该是科学家是主语，所以B不对登录 或 注册 后可以参加讨论
B.同A,介词短语后主语是DNA evidence，this用法错
C.being做修饰不简洁，这里表伴随和结果逻辑都不对，this用法错
D.Skeletons allowed scientists to recover evidence,逻辑有问题，骨骼让科学家去恢复证据？？ and they里的指代主句主语，(svo, and it),骨骼没有能力去推断。it多余
E.主干是Scientists （修饰：啥样的科学家） recovered DNA evidence from which they were able to deduce，就是they were able to deduce from evidence，科学家能去推断，正确。
再不济自己写呀， 不要搬运考满分或者雷哥的啊，里面很多观点都是错的

C后面好像没有they吧~
我觉得是this 不可以指代前面的事情
this 在GMAT中不能当代词用 不过C你也可以理解this的位置容易引起歧义： that后面的从句看起来似乎是同位语修饰this 但是其实根据意思应当是deduce的宾语从句
不是。一个是being able多余，一个是from this太口语化，不正规登录 或 注册 后可以参加讨论
