Answer

Correct Answer: Neither Conclusion I nor II follows

Explanation

Introduction / Context:This item checks whether you draw “some” conclusions from purely universal premises without an existence claim.

Given Data / Assumptions:

  • Pots ⊆ Rings ⊆ Paints.
  • Bangles ⊆ Rings ⊆ Paints.
  • No “some” premise asserting that pots or bangles actually exist.

Concept / Approach:A universal such as “All A are B” does not guarantee that A exists. Therefore we cannot assert “Some B are A” unless existence is independently supplied.

Step-by-Step Solution:C1: “Some paints are pots.” This fails in a model where there are no pots.C2: “Some bangles are paints.” This fails in a model where there are no bangles.Since both conclusions can be false while all premises remain true, neither conclusion necessarily follows.

Verification / Alternative check:Empty-set countermodels: Let Pots = ∅ and Bangles = ∅, Rings = Paints = any set. All universals hold; both “some” conclusions fail.

Why Other Options Are Wrong:Any option claiming I, II, or both follow ignores the need for existential import.

Common Pitfalls:Illicit conversion of universals into particulars (assuming existence without a “some” premise).

Final Answer:Neither Conclusion I nor II follows.
