GWD-26-18 what's the best answer?

Q18

A medieval manuscript called L contains all eighteen extant tragedies

by the Greek playwright Euripides. Of these, 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 com-

mentary in any extant medieval manuscript.

I think all answers are wrong, help me out!

E吧

Electra本身没有评论，自然其它的书里也不会有。

注意限定词

A medieval manuscript called L contains all eighteen extant tragedies by the Greek playwright Euripides

L包含了所有的希腊剧作家Euripides写的。【all】

但是E只是说any other啊~~而文中只说它在L里面没有评论啊~~

I also think all the answers are wrong.

appear in other medieval manuscripts;

From the above statement, I will only have to pick E even though it is not perfect.

结论题，

背景信息说，L里有评论的十个select plays,在其它的书里都有

然后告诉我们说，E是L里没有评论的8个palys之一

问能得出什么结论

我们只能说E在其它地方也没有评论。结论题是单向的思维，抓住信息点，不需要去反驳它
