Difficulty: Medium
Correct Answer: Neither I nor II follows
Explanation:
Given data
Concept/Approach (why this method)
Premise 2 tells us only that the Horses set intersects Tigers somewhere; it does not say that it intersects the particular subset 'Jungles'. Either overlap or disjointness with 'Jungles' is possible.
Step-by-Step calculation / logic
1) If the Horses subset inside Tigers coincides with Jungles, I could be true; if it sits outside Jungles, I is false.2) Because both I and its negation are possible under the premises, neither I nor II is a necessary conclusion.
Verification/Alternative
Two models consistent with premises: (A) Horses ∩ Jungles ≠ ∅ (I true); (B) Horses ∩ Jungles = ∅ (II true). Since truth varies by model, neither follows.
Common pitfalls
Final Answer
Neither I nor II follows.
