Answer
Correct Answer: Only II can be concluded
Explanation
Introduction / Context:This is a standard syllogism with a particular affirmative and a universal conditional. We test which conclusions necessarily follow without committing illicit conversions.
Given Data / Assumptions:
- Some Indians are educated (∃x: Indian(x) ∧ Educated(x)).
- All educated persons like small families (Educated(x) → LikesSmallFamily(x)).
Concept / Approach:Chain the particular instance with the universal rule: if some Indians are educated and all educated like small families, then those particular Indians like small families. Be careful: from “All educated like small families,” you cannot infer “All who like small families are educated.”
Step-by-Step Solution:1) From A: pick an Indian who is educated.2) From B: that person likes small families.3) Therefore, there exists at least one Indian who likes small families ⇒ Conclusion II follows.4) Conclusion I (“All small families are educated”) reverses the conditional and overgeneralizes; it does not follow.
Verification / Alternative check:A simple Venn/arrow diagram confirms: Indian ∩ Educated maps into LikesSmallFamily; existence is preserved.
Why Other Options Are Wrong:“Both” wrongly accepts the illicit converse; “Only I” is invalid; “Neither” ignores the valid existential inference.
Common Pitfalls:Confusing “all A → B” with “all B → A”; forgetting that “some” is enough to derive “some Indians like small families.”
Final Answer:Only II can be concluded.
