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. 答案是E，但我觉得D更可靠。因为E中概念放大了，原文只说在L中not accompanied by a com- mentary mentary |
