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's 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.

Passage Statement Visualization and Linkage
A medieval manuscript called L contains all eighteen extant tragedies by the Greek playwright Euripides. Establishes total scope:
  • Manuscript L = Complete collection
  • Total plays = 18 tragedies
  • This is the universe of all surviving Euripides tragedies
Of these, ten called the "select plays," are accompanied in L by ancient commentaries and also appear in other medieval manuscripts Defines Group 1 - "Select Plays":
  • Count: 10 plays
  • Have ancient commentaries in L
  • Appear in other medieval manuscripts
  • Pattern: Popular/widely preserved works
this group includes some of Euripides' best-known works, including the Medea Confirms select plays' status:
  • Medea = example of select play
  • Best-known works fall into the "select" category
  • Reinforces pattern of popularity/preservation
The other eight, which appear only in L, are called "alphabeticals", because they appear in alphabetical order, without commentary. Defines Group 2 - "Alphabeticals":
  • Count: \(18 - 10 = 8\) plays
  • Appear ONLY in manuscript L
  • NO ancient commentaries
  • Arrangement: Alphabetical order
  • These are rarer, less popular works
The Electra is one of the alphabetical. Categorizes specific play:
  • Electra = alphabetical play
  • Therefore: Electra appears only in L
  • Therefore: Electra has no ancient commentary
  • Electra is among the less widely preserved works
Overall Implication Key Pattern Revealed: Manuscript L preserves a complete spectrum of Euripides' works - both the popular plays that survived in multiple manuscripts (10 select plays with commentary) and the rare plays that survived nowhere else (8 alphabeticals without commentary). This creates two distinct categories based on historical preservation and scholarly attention.

Valid Inferences

Inference: The Electra does not appear in any medieval manuscript other than L.

Supporting Logic: Since the passage states that alphabetical plays "appear only in L" and that "The Electra is one of the alphabetical," we can definitively conclude that Electra exists exclusively in manuscript L. This directly contrasts with the select plays, which "also appear in other medieval manuscripts."

Clarification Note: While we know Electra appears only in L, the passage does not provide information about why this occurred or whether Electra might be well-known despite its limited manuscript presence.

Answer Choices Explained
A
Only Euripides' best-known works are accompanied by ancient commentaries in extant medieval manuscripts.
'Only Euripides' best-known works are accompanied by ancient commentaries in extant medieval manuscripts.' This goes too far beyond what we can conclude. While we know that some of Euripides' best-known works (like Medea) are among the select plays with commentaries, the passage doesn't give us information about ALL best-known works or whether ONLY best-known works have commentaries. We can't make this sweeping generalization.
B
The select plays are accompanied by ancient commentaries because they were the best known of Euripides' works.
'The select plays are accompanied by ancient commentaries because they were the best known of Euripides' works.' This assumes causation that isn't established in the passage. We know the select plays include some best-known works and have commentaries, but the passage doesn't tell us that being well-known is the reason they have commentaries. We can't conclude the 'because' relationship.
C
No commentaries were written about Euripides' Electra in ancient times.
'No commentaries were written about Euripides' Electra in ancient times.' This is too absolute and goes beyond what we can conclude. The passage only tells us that Electra appears without commentary in medieval manuscripts. We have no information about whether commentaries were written in ancient times but simply didn't survive or weren't included in medieval manuscripts.
D
Euripides's Medea never appears in medieval manuscripts unaccompanied by ancient commentary.
'Euripides's Medea never appears in medieval manuscripts unaccompanied by ancient commentary.' The passage tells us Medea is one of the select plays, which are accompanied by commentaries in L and appear in other manuscripts. However, we don't know definitively whether Medea appears with commentary in ALL other medieval manuscripts where it appears. The word 'never' makes this conclusion too strong.
E
Euripides' Electra does not appear accompanied by a commentary in any extant medieval manuscript.
'Euripides' Electra does not appear accompanied by a commentary in any extant medieval manuscript.' This is exactly what we can reliably conclude. Since Electra is an alphabetical play, it appears only in manuscript L and without commentary. Therefore, it doesn't appear with commentary in L, and it doesn't appear at all in any other medieval manuscript. This conclusion follows directly and completely from the given information.
