请教XDF蓝皮书27题

搜了各种资料，包括大全，都没有找到这道题，请哪位帮我解释一下或者链接一下以往的贴，谢谢！

27. A medieval manuscript called L contains all eighteen extant tragedies by the Greek playwright Euripides. Of course, ten called the 'select plays', are accompanied in L by ancient commentaries and also appear in other medieval manuscripts; this group includes some of Euripides' best-known works, including the Medea. The other eight, which appear in alphabetical order, without commentary. The Electra is one of the alphabeticals.

Which of the following can be reliably concluded on the basis of the statements given?

A. Only Euripides' best-known works are accompanied by ancient commentaries in extant medieval manuscripts.

B. The select plays are accompanied by ancient commentaries because they were the best known of Euripides' works.

C. No commentaries were written about Euripides' Electra in ancient times.

D. Euripides' Medea never appears in medieval manuscripts unaccompanied by ancient commentary.

E. Euripides' Electra does not appear accompanied by a commentary in any extant medieval manuscript.

答案是E，但是从原文，如何推出Electra在any现存的中世纪手稿中都没有评论呢？（原文只说它在L中没有评论）

如果把18个戏剧看作分析主体，而不是L手稿，就应该能理解了。10个剧本，在L中有评论且出现在其他手稿中；另外8个，没有评论。觉得这里的without commentary的范围应该是所有的手稿。

另外，用排除法，ABCD肯定不对, 只有E还能凑合着理解下了，呵呵。

谢谢，有点道理。

但还是无法完全说服我：－）原文可以这样省略吗？呵呵
