Syllogism — Players, Spectators, Theatres, Dramas Statements: • All players are spectators. • Some spectators are theatres. • Some theatres are dramas. Conclusions: I. Some dramas are spectators. II. Some players are dramas. III. Some theatres are players. IV. All spectators are players.

Difficulty: Easy

Correct Answer: None follows

Explanation:


Introduction / Context:
This problem mixes one universal inclusion with two independent “some” statements. The key insight is that independent “some” overlaps may concern different elements, so you cannot automatically combine them to create a new intersection.



Given Data / Assumptions:

  • Players ⊆ Spectators.
  • There exists Spectator ∩ Theatre.
  • There exists Theatre ∩ Drama.


Concept / Approach:
Two separate “some” statements about Spectator∩Theatre and Theatre∩Drama do not ensure a common theatre element linking spectators to dramas. Without that shared witness, you cannot deduce “Some dramas are spectators.” Similarly, derived claims about players (a subset of spectators) also fail.



Step-by-Step Solution:

I. “Some dramas are spectators” — not forced; the theatre that is a spectator may be different from the theatre that is a drama.II. “Some players are dramas” — not forced; even if some spectators were dramas, they might not be players.III. “Some theatres are players” — not forced; the “some spectators are theatres” could involve spectators who are not players.IV. “All spectators are players” — false converse of the given inclusion.


Verification / Alternative check:
Model two distinct theatre elements: T1 that is a spectator and T2 that is a drama; keep T1 ≠ T2. All premises hold and none of the four conclusions is compelled.



Why Other Options Are Wrong:

  • Any option asserting I–III assumes a shared witness not provided.
  • IV reverses the subset and is invalid.


Common Pitfalls:
Chaining “some” statements as if they were “all”; reversing subset relations.

None follows
