Difficulty: Easy
Correct Answer: Only conclusion I follows
Explanation:
Introduction / Context:The task is to deduce what must be true from two premises linking politicians, intelligence, and women.
Given Data / Assumptions:
Concept / Approach:Chain subsets: if some women are politicians, and all politicians are intelligent, then those women are intelligent. Conversely asserting that all intelligent persons are women reverses the direction without support.
Step-by-Step Solution:
Step 1: Pick w with w ∈ Women ∩ Politicians.Step 2: From (a), Politicians ⊆ Intelligent, hence w ∈ Intelligent.Step 3: Therefore, 'Some women are intelligent' holds.Step 4: Nothing implies Intelligent ⊆ Women, so II fails.Verification / Alternative check:Countermodel for II: there can be intelligent men; II is thus not necessary.
Why Other Options Are Wrong:
Common Pitfalls:Confusing subset direction in universal statements.
Final Answer:Only conclusion I follows.
