Difficulty: Medium
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:
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.
